However, further and/or other applications are feasible.
The designing of components and parts is a central aspect of development processes performed in small and large scale manufacturing and/or producing industry. Specifically, in chemical industry, the designing of a shape of steam reforming catalysts is a conventionally performed procedure, typically aiming at improving catalyst performance. Thus, in general, a complex and elaborate designing of the shape of steam reforming catalysts is performed. Thus, in “Optimum dimensions of shaped steam reforming catalysts” by Kagyrmanova et al. published in the chemical Engineering Journal 134 (2007) 228-234 a theoretical optimization of shaped catalyst dimensions with technologically imposed constraints for operating conditions of a typical methanol reformer is described. Further, in “Catalyst shape as a design parameter—optimum shape for methane-steam reforming catalyst” by Soltan Mohammadzadeh and Zamaniyan published by the Institution of Chemical Engineers Trans IChemE, Vol 80, Part A in May 2002, a mathematical model for simulation of a catalytic terrace wall methane-steam reformer has been developed. Further, in “Optimal Shape Design of an Extrusion Die Using Polynomial Networks and Genetic Algorithms” by C.-Y. Wu et al. published in the International Journal of Advanced Manufacturing Technology 19 (2002) 79-87 a design method for the optimum shape design of extrusion die is described, wherein the extrusion die was modelled and analyzed by using the finite-element method, a polynomial network was applied to identify force and strain models and an improved genetic algorithm was used to optimize the identified model for optimal shape with minimum force and strain. Further, in “Application of a genetic algorithm to the optimal design of the die shape in extrusion” by J. S. Chung et al. published in the Journal of Materials Processing Technology 72 (1997) 69-77 an approach to the optimal design on the die shape in extrusion is described, wherein optimization of the design variable is conducted by a genetic algorithm, where the fitness values are evaluated on the basis of a finite element method analysis model. The approach is applied to the determination of the die shaped that are optimal with regard to various objective functions. Further, in “Multiobjective optimization design of porthole extrusion die using Pareto-based genetic algorithm” by Guoqun Zhao et al. published in the International Journal of Advanced Manufacturing Technology 69 (2013) 1547-1556 a multiobjective optimization for porthole extrusion die based on modern intelligence algorithm is described, aiming at achieving the uniform velocity distribution in the cross-section of the profile as well as decreasing the maximum stress on the extrusion die and the deflection of the mandrel. The Kringing model is established on the basis of Latin hypercube samplings, and above design variable are optimized using Pareto-based genetic algorithm. Further, in “Optimal Shape Design of an Extrusion-Forging Die Using a Polynomial Network and a Genetic Algorithm” by C.-Y. Wu et al. published in the International Journal of Advanced Manufacturing Technology 20 (2002) 128-137 obtaining an optimal shape of an extrusion-forging die in consideration of the influence of metal flow deformation in extrusion-forging processes is described, wherein finite-element method is used to analyze the effects of different die shapes on extrusion-forging deformation, a polynomial network is used to construct the relationship model and a genetic algorithm is used to obtain the optimal shape of the extrusion forging die. Furthermore, in “Metal-forming process optimisation by inverse evolutionary search” by C. A. Conceição António et al. published in the Journal of Material Processing Technology 121 (2002) 403-413 a development of new numerical techniques for the optimization of steady and non-steady forming processes is described, wherein the inverse problem formulation together with evolutionary search schemes are considered. Therein, numerical algorithms based on a genetic search supported by an elitist strategy are used.
Further, in general, shape optimization is performed in multiple development processes. As an example, US 2016/0004793 A1 describes a method for analysis of shape optimization including: setting, as a design space, a portion to be optimized in a movable portion; generating, in the set design space, an optimization block model formed of three-dimensional elements and is to be subjected to analysis processing of optimization; connecting the generated optimization block model with a structural body model; setting a material property for the optimization block model; setting an optimization analysis condition for finding an optimum shape of the optimization block model; setting a multi-body dynamics analysis condition for performing multi-body dynamics analysis on the structural body model with which the optimization block model has been connected; and executing, based on the set optimization analysis condition, the multi-body dynamics analysis on the optimization block model and finding the optimum shape of the optimization block model. US 2007/0050068 A1 describes an optimization method for optimizing a shape of a component including the steps of setting information including a shape of each part in the component to plural parameters, extracting a relationship between the plural parameters and a deformation of the component, changing a value of at least one of the plural parameters so as to reduce a deformation of the component, and adjusting a volume of the component.
In US 2003/0083763 A1 a method and a device enabling any operator even without skill to efficiently, constantly determine an optimum packaging specification of vehicle parts, or the like, is described.

Based on the protective property determined, at least one of packaging materials classified in property is determined for packaging the article, then a packaging form is determined from the determined packaging material and the article property, and a packaging order of the determined packaging form is determined according to packaging priorities preset for such packaging forms.

The method calculates the tangential inlet area for each throttleable stage. The method also uses correlation between the tangential inlet areas and delta pressure values to calculate the spring displacement and variable inlet geometry of a liquid rocket engine swirl injector.
Further, in DE 103 42 147 B4 a process for automatically calculating a deformation compensating geometry for a forming tool is described. The process comprises determining the starting geometry and altering it according to the deviation from a threshold value. The starting geometry is approximated by surface elements, and junction points are determined for each element. The difference vector for each starting point is calculated, along with an average vector, and the junction point is moved about the average vector. The surface elements are triangles.
However, constantly evolving manufacturing possibilities require alterations in the developing process of manufacturing processes. Thus, in designing components and manufacturing processes several technical challenges exist. Typically, in every phase of the developing process, specifically when designing and creating geometries of components and parts, input from technical experts is required, such as in the field of mechanical engineering, chemical engineering, chemistry, material sciences or physics, e.g. for constructing and interpreting models, simulations and calculations. In particular, designing methods and systems require the performance of complex calculations and intensive computing. Generally, designing methods and systems comprise iterative processes, wherein it is required to iteratively adapt calculations, models and simulations.
Thus, generally, the performing of such methods is very time-consuming, costly and complex.
It is therefore desirable to provide means and methods which address the above mentioned technical challenges of designing components and parts, such as shaped bodies and dies, or manufacturing processes for manufacturing such components. Specifically, methods computer programs and systems shall be proposed for improving the process of designing at least one shaped body or shaping tool, e.g. a die, and their respective manufacturing processes, compared to methods, computer programs and systems known in the art.

In particular, the shaped body may be produced or manufactured in a quantity ranging from 1 to 100000 kg per hour, preferably from 5 to 50000 kg per hour, more preferably from 50 to 20000 kg per hour. Thus, as an example, the shaped body may be configured to be produced or manufactured by one or more of an extrusion process and a tableting process, such as by using an extrusion machine or a tableting machine.
Specifically, the shaped body may be configured to be produced and/or manufactured by at least one of an extrusion process and a tableting process. However, parallel production, such as parallel production and/or manufacturing of the shaped body by more than one extrusion and/or tableting process may be possible. In particular, the above-mentioned manufacturing quantity for the shaped body may be valid for one extrusion process and/or one tableting process, specifically for one production unit, such as for one extruder of the extrusion process or for one press of the tableting process. Thus, as an example, the manufacturing quantity may multiply according to a number of production units used for production, such as according to the number of extruders and/or presses used in parallel within the extrusion process and/or the tableting process.
As an example, the shaped body may be or may comprise a molded body and/or a molded part, such as an object and/or component generated by making use of at least one forming process, e.g. a molding process.

In particular, the shaped body may be a molded body and/or part, molded by using at least one forming and/or molding process, such as for example an extrusion process and/or a tableting process.
The term “retrieving” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to a process of a system specifically a computer system, of generating data and/or obtaining data from an arbitrary data source, such as from a data storage, from a network or from a further computer or computer system. The retrieving specifically may take place by at least one computer interface, such as via a port such as a serial or parallel port. The retrieving may comprise several sub-steps, such as the sub-step of obtaining one or more items of primary information and generating secondary information by making use of the primary information, such as by applying one or more algorithms to the primary information, e.g. by using a processor. Further, the retrieving may comprise obtaining data from one or more of at least one measurement, at least one calculation, literature, at least one handbook, knowledge, experience and at least one reference simulation. In particular, the retrieving in step a) may be or may comprise providing the set of target criteria to at least one processor of a computer, such as of the computer on which the computer-implemented method is performed. Thus, the retrieving in step a) may be or may comprise providing the set of target criteria to the processor, such by using at least one interface, e.g. of the computer.
The term “target criterion” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to a characteristic or specification which is targeted and/or aimed at when designing an arbitrary object or element. In particular, the target criterion may be or may comprise at least one reference characteristic and/or property with which a characteristic of the object and/or element is compared. As an example, the target criterion may be compared with at least one simulated criterion of the shaped body. Specifically, the target criterion may be a characteristic or specification for an application of the object or element, such as for an application of the shaped body. Thus, as an example, the target criterion may be or may comprise at least one characteristic, such as a reference characteristic, according to which the parameter, e.g. comprising the at least one geometry parameter of the seed geometry, is adapted. In particular, a plurality of target criteria may be referred to as being a set of target criteria.
The term “seed geometry” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to an arbitrary primary and/or initial two-dimensional and/or three-dimensional form or shape. In particular, the seed geometry may be or may comprise a three-dimensional basic type of the shaped body. Thus, the seed geometry may, for example, be an initial geometry for the shaped body, when designing the at least one shaped body. As an example, the seed geometry may be a predefined basic type of the shaped body. In particular, the seed geometry may be a two-dimensional and/or three-dimensional structure which may be described by using geometric forms, such as, for example, a cylinder, a pyramid, or the like. Additionally or alternatively, other computer and/or mathematical methods may be used for describing the seed geometry, such as one or more of at least one equation, at least one vector and at least one matrix. Additionally or alternatively, the seed geometry may be a combination of two-dimensional and/or three-dimensional structures and/or geometric forms, such as, for example, a pyramid with a cylindrical hole, or the like.

The seed geometry may, for example, be or may comprise a computer-generated geometry, such as a geometry automatically generated by a computer, e.g. by using at least one algorithm dedicated to generating geometries.
Thus, in other words, the seed geometry may refer to a starting geometry for the shaped body, when designing the shaped body, such as a starting point of the shaped body geometry. Specifically, the seed geometry may refer to a geometry being the starting geometry in the method for designing the at least one shaped body, such as to a starting geometry for the shaped body in the process of designing. Thus, the seed geometry may specifically refer to an initial geometry, such as the geometry at a beginning or starting point of the method. Specifically, the seed geometry may be the initial geometry of the shaped body at the beginning and/or start of the designing method, such as at an initial point of the simulation and/or optimization, e.g. of the simulating of step d) of the method. In particular, the seed geometry may refer to a start-point in the described computer-implemented method, which may subsequently be altered, for example in a simulation and/or optimization process, in order to reach one or more adequate results, such as at least one lead candidate geometry, e.g. as outlined in further detail below.
As used herein, the term “defining the seed geometry” may refer to one or more of generating, selecting and determining the seed geometry.

Thus, the defining in step b) may comprise providing the seed geometry to the processor, such by using at least one geometry defining unit, e.g. of the computer.
The term “parameter” as used herein is a broad term and is to be given its ordinary and customary meaning to a person skilled in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to an arbitrary variable representing at least one physical property of an object or system, wherein a value of the variable determines at least one characteristic or behavior of the object or system. In particular, the parameter may represent at least one property of the seed geometry, specifically of the seed geometry for the shaped body, such as a measured, calculated, estimated or tabulated property. Thus, the set of parameters may specifically be or may comprise at least one geometry parameter of the seed geometry, such as a parameter relating to a geometry and/or shape of the seed geometry. The parameter may be at least one variable selected from the group consisting of: a geometry parameter, e.g. a length, a thickness, a horizontal expansion and/or a vertical expansion, a side crush strength, a bulk crush strength; a material parameter, such as a Young's modulus, a hardness, an elasticity, a shear strength, a tensile strength, a heat capacity and/or a thermal conductivity; a chemical parameter, e.g. a reaction rate, a chemical conversion, a reaction yield and/or a reaction selectivity. In particular, the parameter may be one or more of a bulk density, a packed density, a weight, a surface area, a pore structure, an attrition rate, a flowability index, a diffusion coefficient, and the like, e.g. as described in “Handbook of Heterogeneous Catalysis” by Schuth et al. second, completely revised and enlarged edition, volume 1, p. 676-698. As used herein, the term “generating a set of parameters” refers to determining a plurality of parameters from the seed geometry.
In particular, step c) of generating a set of parameters comprising at least one geometry parameter of the seed geometry may further comprise one or more sub-steps, such as a sub-step of providing the set of parameters to at least one processor of a computer, such as of the computer on which the computer-implemented method is performed. Thus, the generating in step c) may further comprise providing the set of parameters to the processor, such by using at least one parameter generating unit, e.g. of the computer.
In particular, the set of parameters of the seed geometry, such as a set of variables determining at least one characteristic or behavior of the seed geometry for the shaped body, may, for example, be adapted or changed according to the target criteria, when simulating the shaped body in step d). As used herein, the term “simulating” is a broad term and is to be given its ordinary and customary meaning to a person skilled in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to a process of applying at least one simulation tool, such as an algorithm and/or a neural network, to an arbitrary object, such as an input value or initial value, for the purpose of determining at least one expected value and/or characteristic of the object.
Thus, in other words, the simulating may be or may refer to a process of optimizing. In particular, the process of simulating by applying the at least one simulating tool, such as repeatedly and/or iteratively applying one or more simulating tools, e.g. as outlined above or as described in further detail below, to an arbitrary object may synonymously be referred to as a process of optimizing, such as an optimization of at least one input value.
Specifically, as used herein, the term “simulating the shaped body” may refer to a process of applying at least one simulation tool to the set of generated parameters for the purpose of determining at least one adapted set of parameters of the shaped body. In particular, simulating the shaped body may comprise iteratively varying values of the set of parameters and determining for each value of at least one parameter at least one simulated criterion of the shaped body. Further, the at least one simulated criterion may be compared with at least one target criterion of the set of target criteria, in order to determine the values of the set of parameters for which the shaped body fulfills, at least within predetermined tolerances, the set of target criteria. As an example, the purpose of simulating the shaped body may specifically be or may comprise generating at least one adapted set of parameters, for example identifying at least one form or shape for the shaped body, for which the target criteria are fulfilled.
As used herein, the term “varying values of the set of parameters”, may refer to a process of changing a value of at least one parameter of the set of parameters, which may specifically be performed iteratively. In particular, the values of the set of parameters may be varied by following one or more of a preset and/or a predetermined pattern, a preset and/or a predetermined algorithm, a preset and/or a predetermined mathematical set of rules, a preset and/or a predetermined method or a preset and/or a predetermined protocol. Alternatively, the values of the set of parameters may be varied randomly.
In particular, simulating the shaped body, specifically in step d), as outlined above, may be or may comprise an iterative process, specifically an optimization process. Thus, as an example, when simulating the shaped body, specifically in step d), the set of parameters of the seed geometry, such as the values of a set of variables determining at least one characteristic or behavior of the seed geometry for the shaped body, may be changed and/or varied, e.g. randomly and/or by following one or more predetermined patterns. These changed parameters, e.g. the changed and/or varied values of parameters, when simulating the shaped body in step d), may then be analyzed, e.g. subsequently, in order to determine whether or not for these changed parameters the shaped body fulfills the set of target criteria, e.g. falls within predetermined tolerances of the target criteria. Again, as outlined above, this procedure may be performed iteratively, such as in case the target criteria are not met, e.g. as is commonly known in optimization procedures. As an example, if the shaped body having the geometry of the changed and/or varied parameters, e.g. of the changed and/or varied values of the set of parameters, does not fulfill the set of target criteria, the parameters, e.g. the values of the set of parameters, may again be changed and/or varied. Thus, as outlined above, e.g. in the previous paragraph, when simulating the shaped body in step d), the varying of the values of the set of parameters may specifically be performed iteratively, e.g. until a set of parameters, specifically values of the set of parameters, are such that the shaped body fulfills the set of target criteria, at least within predetermined tolerances.
As used herein, the term “simulated criteria”, may refer to at least one value and/or characteristic to be expected of a simulated object, in particular of the simulated shaped body having a certain set of parameters. Thus, the simulated criteria, specifically the simulated criteria of the shaped body, may for example be or may comprise at least one value and/or characteristic of the shaped body to be expected, in case the geometry of the shaped body equals a simulated geometry, such as the geometry as described by the values of the set of parameters used in the simulation, e.g. as described by the simulated values.
As used herein, the term “adapted set of parameters”, may refer to at least one set of values describing the shaped body, e.g. the geometry of the shaped body, for which the target criteria are fulfilled at least within predetermined tolerances. Thus, the adapted set of parameters may specifically be or may comprise at least one outcome of simulating the shaped body. In particular, in step d), the set of parameters may be adapted by comparing simulated criteria, such as simulated characteristics or specifications, for varying values of the set of parameters with the set of target criteria. Thus, an adapted set of parameters may be generated, for which the target criteria are fulfilled at least within predetermined tolerances.
In other words, the adapted set of parameters may specifically refer to an adapted set of values of parameters. Thus, the adapted set of parameters, e.g. the set of adapted values of parameters, may specifically refer to a set of adapted parameter values for which the target criteria are fulfilled, e.g. at least within predetermined tolerances.
The term “fulfilled” as used herein is a broad term and is to be given its ordinary and customary meaning to a person skilled in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to an achievement of an arbitrary goal, such as complying with at least one predefined or preset criterion. Thus, the term “fulfilled at least within predetermined tolerances” specifically may refer, without limitation, to an arbitrary status of reaching a predefined goal by complying with the at least one predefined or preset criterion, wherein a predetermined tolerance may be applied when determining the achievement.
The term “the target criteria are fulfilled at least within predetermined tolerances” refers to the fact that the target criteria are completely fulfilled wherein deviations are possible within the predetermined tolerances. In detail, the adapted set of parameter as generated in step d) may define a geometry of the shaped body for which the target criteria may be fulfilled or achieved, wherein an optimum may be missed so long as a discrepancy or deviation is smaller than the predetermined tolerances. As an example, the target criteria may be considered being fulfilled so long as an optimum or maximum fulfillment of the target criteria may be reached. Specifically, the target criteria may be fulfilled so long as a maximum or minimum, for example a global maximum or a global minimum, of at least one target criteria is reached. Thus, the target criteria may be considered to be fulfilled or achieved so long as a minimum discrepancy and/or a minimum deviation is reached. Additionally or alternatively, the target criteria may be fulfilled at least within predetermined tolerances as long as a difference or discrepancy between the simulated criteria and the target criteria is smaller to or equals the predetermined tolerances. Specifically, the target criteria may be considered to be fulfilled so long as the simulated criteria and the target criteria differ from each other by no more than 50%, preferably by no more than 20%, more preferably by no more than 10%.
The term “geometry” as used herein is a broad term and is to be given its ordinary and customary meaning to a person skilled in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to a two-dimensional and/or three-dimensional form or shape of an arbitrary object. The geometry may specifically be described and/or defined mathematically, e.g. by a mathematical function. Additionally or alternatively, the geometry may be described by using at least one data format generally used by computers, e.g. computer methods for describing geometries, such as one or more of: a point cloud, at least one vector, at least one matrix, a constructive solid geometry (CSG) representation and a hybrid method.
The term “lead candidate geometry” as used herein is a broad term and is to be given its ordinary and customary meaning to a person skilled in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to a form or shape of the at least one shaped body for which the target criteria are fulfilled at least within predetermined tolerances. Thus, it may specifically be possible to determine multiple lead candidate geometries for all of which the target criteria are fulfilled at least within predetermined tolerances. In particular, the at least one lead candidate geometry may be determined from the adapted set of parameters as generated in step d). As an example, the lead candidate geometry may be determined from the adapted set of parameters by transforming the values of the adapted set of parameters into a mathematical description, such as into a mathematical function, describing the geometry of the shaped body for which the target criteria are fulfilled. In particular, the lead candidate geometry may be or may comprise a negative geometry of a starting geometry used when designing at least one die, e.g. for manufacturing the shaped body.
In particular, the lead candidate geometry may specifically be or may refer to a geometry being the result of the designing method, such as the outcome of the simulation and/or optimization. Specifically, the lead candidate geometry may be the result of the simulating of step d) of the method. Thus, the lead candidate geometry may be the resulting geometry for the shaped body, when performing the designing method, such as the outcome of the designing method. In particular, the lead candidate geometry may refer to an output of the described computer-implemented method. Specifically, the lead candidate geometry may be a two-dimensional and/or tree-dimensional structure, whose basic shape may be similar to the seed geometry. In particular, with respect to the seed geometry, the basic shape of the lead candidate geometry may remain unamended, such that e.g. a cylinder remains a cylinder, a pyramid remains a pyramid, a cube remains a cube, and the like. Thus, as an example, in case the target criteria are already fulfilled for the seed geometry, the lead candidate geometry may only slightly differ from the seed geometry or even equal the seed geometry.
The set of target criteria in step a) may be retrieved via at least one interface, specifically, via at least one web interface. The term “interface” as used herein is a broad term and is to be given its ordinary and customary meaning to the person skilled in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to an item or element forming a boundary configured for transferring information. In particular, the interface may be configured for transferring information from a computational device, e.g. a computer, such as to send or output information, e.g. onto another device. Additionally or alternatively, the interface may be configured for transferring information onto a computational device, e.g. onto a computer, such as to receive information. The interface, e.g. the web interface, may specifically provide means for transferring or exchanging information, in particular, online, such as via internal or external, for example by an Internet connection. In particular, the interface may provide a data transfer connection, e.g. Bluetooth, NFC, inductive coupling or the like. As an example, the interface or port may be or may comprise one or more of a network or Internet port, a USB-port and a drive disk. In particular, the web interface may be or may comprise one or more of a software interface, a script, a database interface.
Further, the at least one lead candidate geometry of the shaped body may be output via the at least one interface. The term “output” as used herein is a broad term and is to be given its ordinary and meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to the process of making information available to another system, data storage, person or entity. As an example, the output may take place via one or more interfaces, such as a computer interface, a web interface or a human-machine interface. The output, as an example, may take place in one or more of a computer-readable format, a visible format or an audible format.
The target criteria may specifically contain at least one constraint selected from the group consisting of: a geometry constraint, such as a production machine tolerance, a wall minimum thickness, a tabletability constraint, an extrudability constraint, a maximum and/or minimum diameter constraint, a maximum and/or minimum height constraint, specifically a geometric constraint referring to dimensions of existing shaping machines or existing application reactors, e.g. an adequate die filling height, a tableting pressing force, an adequate rotation speed, an adequate throughput, a long term stability of tableting parameters, an adequate ejection force, a maximum torque, an extrusion pressure, an extrusion throughput; a weight constraint, specifically a weight constraint referring to a maximum weight inside an application reactor in which the shaped body may be applied; a surface area constraint, such as a maximum surface area per weight, a maximum Brunauer-Emmett-Teller (BET) surface area; a density constraint; a mechanical strength constraint, a compressive crushing strength, a tensile strength, a shear strength, a bending strength, a torsion strength, a cutting strength, an attrition, an abrasion, an elasticity, a torsion strength; a pressure drop constraint; a heat transport constraint; a mass transport constraint; a productivity constraint; a shaping process constraint; an economic constraint, e.g. a production cost, a sales price, a profit margin, a line productivity. In particular the target criteria may for example contain at least one constraint coming from a shaping process or existing due to a shaping limitation of the shaping process.
In particular, the set of target criteria may comprise at least one mechanical strength constraint and/or at least one pressure drop constraint or may even consist of the at least one mechanical strength constraint and/or the at least one pressure drop constraint.
In particular, at least one of the target criteria of the set of target criteria may comprise at least one condition to be fulfilled by the shaped body. Thus, the shaped body, for example, may need to fulfill the at least one condition of the at least one target criterion in order for the target criteria to be considered fulfilled.
Further, as an example, the condition may be a condition to be fulfilled by a measurable property of the shaped body. Thus, the shaped body may specifically comprise at least one measurable property, wherein, in order for the shaped body to be considered to fulfill the target criteria, the at least one measurable property of the shaped body may, for example, need to fulfill the at least one condition of the at least one target criterion. The term “measurable property” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to an arbitrary qualitatively or quantitatively determinable characteristic or specification of an object or element. Thus, the measurable property of the shaped body may particularly refer to a qualitatively or quantitatively determinable characteristic of the shaped body.
In particular, the measurable property may be selected from the group consisting of: a geometry parameter of the shaped body; a weight of the shaped body; a surface area of the shaped body; a density of the shaped body; a pore structure of the shaped body; a mechanical strength of the shaped body; a pressure drop parameter; a heat transport parameter; a mass transport parameter; a productivity parameter; a elasticity property of a material of the shaped body, specifically a Young module of a material of the shaped body; a shape property, such as a side crush strength, a bulk crush strength, a tensile strength; a chemical conversion parameter, such as a reaction rate, a chemical conversion, a reaction yield, a reaction selectivity, a conveying parameter, such as a flow index.
Specifically, a test and/or a verification, if the condition is fulfilled, may specifically comprise a comparison of the measurable property with at least one numerical value. In particular, the test and/or verification of fulfillment of the condition may, for example, comprise a comparison of the measurable property with at least one of: a single numerical value, specifically a threshold value; a plurality of numerical values, specifically a range; a target value.
The condition may, for example, be a condition to be fulfilled by a qualitative property of the shaped body. Specifically, as an example, the condition may be a condition to be fulfilled by a qualitative property of the shaped body or of a variety of shaped bodies, such as of a variety of shaped bodies in a defined or undefined assembly.
The target criteria may comprise at least one suitability of the shaped body for at least one predetermined application purpose. Specifically, as an example, the target criteria may comprise at least one suitability of the shaped body selected from the group consisting of: a suitability for application in a predetermined reactor, a suitability for application under predetermined pressure, a suitability for application at a predetermined temperature, a suitability for application with at least one predetermined reactant, a suitability for application in a predetermined reaction, a suitability for application under at least one predetermined flow condition, a suitability for application in at least one predetermined mass flow, a suitability for application in at least one predetermined heat flow, a suitability for application under at least one predetermined mechanical stress.
The retrieving may comprise a preprocessing, specifically a preprocessing of at least one target criterion of the set of target criteria. As an example, step a), particularly the preprocessing, may further comprise weighing the target criteria. In particular, when retrieving the at least one set of target criteria for the shaped body in step a), the target criteria may further be weighed, such as ranked or given equal or different priorities. For example, in case individual target criteria from the set of target criteria may be considered more or less important than other target criteria, these individual target criteria may be given a higher or lower priority. Thus, the target criteria from the set of target criteria may be weighed individually. However, alternatively, each target criteria from the set of target criteria may be considered to be equally important. Thus, each target criteria from the set of target criteria may be weighed equally.
Step a) may further comprise retrieving at least one information on a material to be used for the shaped body. Thus, when retrieving the at least one set of target criteria from the shaped body in step a), additionally, at least one material to be used for the shaped body may be retrieved. Specifically, at least one material property of the at least one material to be shaped by the shaping tool may be retrieved. For example, the material property may be or may comprise one or more of a rheology parameter, e.g. a rheology of a catalyst paste, such as for extrusion, a compressibility compactability curve, such as for tableting, a density, such as a density of a powder to be tableted, e.g. a pill mix, or the like.
The adapted set of parameters in step d) may, for example, be generated by applying at least one operation, e.g. a mathematical and/or logical method, selected from the group consisting of: a non-linear algorithm; a stochastic algorithm; a genetic algorithm; an artificial intelligence algorithm; a gradient-based algorithm; a multi-criteria optimization function, specifically at least one of a weighted sum function or an E-constraint function; sequential quadratic programming; method of feasible directions; quasi-newton method; newton method.
In particular, the adapted set of parameters may, as an example, be generated by performing an optimization method, such as for example a multi-criteria approach optimization method. Specifically, constraints and/or boundary conditions may be used in the optimization method, such as in the multi-criteria approach. In particular, the at least one constraint may be or may comprise at least one mathematical function, such as a mathematical function constraining the optimization. Thus, as an example, a height being lower than a diameter may be considered a constraint. Further, the at least one boundary condition may specifically be understood as an allowable range, e.g. a range for the parameter space to be searched. Thus, the range between a minimum height and a maximum height may be considered a boundary condition. In particular, the at least one boundary condition may be or may comprise at least one boundary condition from the target criteria, e.g. from the target values and/or limitations due to a production process, such as a production process of the shaped body, or the like. Specifically, in the optimization method, e.g. in the multi-criteria approach optimization method, at least one minimum value and at least one maximum value for a response function may be pre-set, e.g. set as a boundary condition, as an example, for a pressure drop and/or a mechanical strength. As an example, in the multi-criteria approach, the set of parameters, specifically the set of parameters comprising the at least one geometry parameter, may be changed or varied once, repeatedly or in an iterative pattern, such as to determine the at least one adapted set of parameters.
As an example, step d) may further comprise simulating the shaped body by varying values of the adapted set of parameters.
The shaped body may specifically be an element selected from the group consisting of: a packed bed material, such as a packed bed material used in a scrubbing tower or scrubber; a tower packing, such as a wash tower packing; a catalyst, more specifically a catalyst pellet, a catalyst extrudate, a catalyst granulate; an adsorbent, more particularly an adsorbent pellet, an adsorbent extrudate, an adsorbent granulate; a filter. In particular, as an example, the shaped body may be or may comprise at least one or more than one elements of a packed bed, for example used in a scrubbing tower or scrubber, wherein specifically the shaped body may be configured for providing a maximum surface area for fluids, such as a maximum contact area between a gas to be cleaned and a scrubbing liquid. Further, the shaped body may, as an example, be used in a distillation procedure. Specifically, the shaped body may, for example, be applied in moving and/or fluidized and/or entrained bed reactors, such as in any possible packing of a solid phase, such as a solid phase coming into contact with a fluid phase, e.g. with one or more of a liquid phase, a gaseous phase and a supercritical phase.

The method may also be referred to as method, shaping tool designing method, die design method or die designing method. The method comprises the following steps, which may be performed in the given order. However, a different order may also be possible.
Further, one or more than one or even all of the steps may be performed once or repeatedly.
Further, the method steps may be performed in a timely overlapping fashion or even in parallel.
The method may further comprise additional method steps which are not listed.
The computer-implemented method for designing at least one shaping tool comprises the following steps:
The method for designing at least one shaping tool may be used for designing at least one shaping tool, e.g. at least one die, to be used in a granulation process and/or a tableting process, such as in a spray drying process, and/or in an extrusion process. In particular, the method for designing at least one shaping tool may be used for designing at least one shaping tool, e.g. die, to be used in an arbitrary shaping or manufacturing process, wherein various shaping methods, such as granulation and agglomeration, may be used. In particular, the shaping tool and/or die may, for example, be used in a molding process and/or in an additive manufacturing process.
Thus, in particular, the shaping tool and/or die may also be referred to as mold, specifically as a mold configured for being used in a molding process.
As an example, the shaping tool, e.g. the die, may be manufactured for example in a molding process and/or in a machining process and/or in an additive manufacturing process.
Specifically, the shaping tool may be or may comprise at least a part of one or more of a tableting tool and an extrusion die. In particular, the shaping tool may be or may comprise the extrusion die, such as a die used in an extrusion process.

In particular, the tableting process may be configured for transferring a negative form and/or geometry of the tableting tool onto the pressured material. Thus, the tableting process may be or may comprise a compacting process, in which the object or part is formed from the material by applying pressure onto the material, e.g. by compacting the material. In particular, the tableting process may be or may comprise a molding process, using a mold, such as a die, as a form giving entity.

The term specifically may refer, without limitation, to a procedure of planning and/or specifying at least one shaping tool, e.g. at least one die. In particular, the designing of at least one shaping tool may specifically be or may comprise developing and/or defining at least one property of the shaping tool, such as, for example, a geometry and/or shape of the shaping tool.
The term “shaping tool” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to an arbitrary form giving tool. The shaping tool may for example comprise a form or mold, such as a form giving matrix or frame. Specifically, the shaping tool may be used in a shaping process used for manufacturing the shaped body. The shaping tool may specifically be a form giving tool used in an arbitrary shaping or manufacturing process suitable for manufacturing the shaped body.
As an example, the shaping tool may be or may comprise one or more of a tableting tool, specifically a tableting tool comprising a die, and an extrusion die. The shaping tool may specifically be or may comprise the die. Thus, herein the term “die” specifically may refer to at least a part of the shaping tool. Additionally or alternatively, herein the terms “shaping tool” and “die” may be used interchangeably.
The term “shaping target criterion” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to a characteristic or specification which is targeted at when designing an arbitrary shaping object or element. In particular, the shaping target criterion may be or may comprise at least one reference characteristic or property with which a characteristic of the shaping object or element, e.g. a simulated criterion, is compared. Specifically, the shaping target criterion may be a characteristic or specification for an application of the shaping object or element, such as for an application of the shaping tool or die, e.g. for using the shaping tool for shaping or manufacturing the shaped body. Thus, as an example, the shaping target criterion may be or may comprise at least one characteristic, such as a reference characteristic, according to which the shaping parameter, e.g. comprising the at least one shape geometry parameter of the starting geometry, is adapted. In particular, a plurality of shaping target criteria may be referred to as being a set of shaping target criteria.
In particular, the retrieving of the at least one set of shaping target criteria for the die in step i) may be or may comprise providing the set of shaping target criteria to at least one processor of a computer, such as of the computer on which the computer-implemented method is performed. Thus, the retrieving in step i) may be or may comprise providing the set of shaping target criteria to the processor, such by using at least one interface, e.g. an interface of the computer.
The term “starting geometry” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to an arbitrary primary and/or initial two-dimensional and/or three-dimensional form or shape. In particular, the starting geometry may be or may comprise a two-dimensional and/or three-dimensional basic type of a shaping tool and/or die. In particular, the starting geometry for the shaping tool may, for example, be an initial geometry of the shaping tool and/or die, when designing the at least one shaping tool. As an example, the starting geometry for the shaping tool may be a predefined basic type of the shaping tool and/or die, such as a previously determined geometry, and/or a geometry of a previous generation of shaping tools and/or dies. Specifically, the starting geometry for the shaping tool and/or die may be or may comprise a raw form or shape of the shaping tool and/or die. Starting geometry may, for example, be or may comprise a computer-generated geometry, such as a geometry automatically generated by a computer, e.g. by using at least one algorithm dedicated to generating geometries. Additionally or alternatively, the starting geometry may be generated from previously defined starting geometries, such as from experience.
As used herein, the term “defining the starting geometry” may refer to one or more of generating, selecting and determining the starting geometry. The defining of the starting geometry may comprise generating the starting geometry depending on and/or in view of the at least one shaping target criteria. The starting geometry may be a pre-defined starting geometry stored in a data storage of the computer. The data storage may comprise at least one table or at least one lookup table comprising a plurality of different starting geometries. The defining of the starting geometry may comprise selecting one of the starting geometries for example depending on the at least one shaping target criterion.
In particular, step ii) of defining at least one starting geometry for the die, may further comprise one or more sub-steps, such as a sub-step of providing the starting geometry to at least one processor of a computer, such as of the computer on which the computer-implemented method is performed. Thus, the defining in step ii) may comprise providing the starting geometry to the processor, such by using at least one geometry defining unit, e.g. a geometry defining unit of the computer.
The term “shaping parameter” as used herein is a broad term and is to be given its ordinary and customary meaning to a person skilled in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to an arbitrary variable representing at least one physical property of a shaping object or system, wherein a value of the variable determines at least one characteristic and/or behavior of the shaping object or system. In particular, the parameter may represent at least one property of the starting geometry, specifically the starting geometry for the shaping tool. Thus, a set of shaping parameters may specifically be or may comprise at least one geometry parameter of the starting geometry, such as a parameter relating to a geometry or shape of the starting geometry for the shaping tool. In particular, the set of shaping parameters of the starting geometry, such as a set of variables determining at least one characteristic and/or behavior of the starting geometry for the shaping tool, may for example be adapted or changed according to the shaping target criteria, when simulating a shaping process using the shaping tool in step iv). In particular, shaping parameter may represent at least one property and/or behavior of the shaping tool when the shaping tool is used for shaping at least one object. Thus, the set of shaping parameters may specifically be or may comprise at least one shape geometry parameter of the starting geometry. The shaping parameter may be at least one variable selected from the group consisting of: a geometric parameter, e.g. a length, a thickness, a horizontal expansion and/or a vertical expansion, specifically of a cut out and/or a hole and/or a negative geometry, e.g. of a mold or matrix, of the shaping tool; a material parameter of the shaping tool, such as a Young's modulus, a hardness, an elasticity, a shear strength, a tensile strength, a heat capacity and/or a thermal conductivity; a material parameter of the object to be shaped by using the shaping tool, such as a hardness, an elasticity, a shear strength, a tensile strength, a viscosity, a heat capacity and/or a thermal conductivity; a process parameter, such as a pressure, specifically a tableting pressure, and/or a velocity, such as an extrusion velocity. Further, as an example, the shaping parameter may be or may comprise a surface quality, e.g. a roughness and/or smoothness; a shaping machine parameter, such as a boundary condition of a shaping machine, for example a maximum diameter of an extrusion die, e.g. the maximum diameter being limited by a size of an extrusion machine. As used herein, the term “generating a set of shaping parameters” refers to determining a plurality of shaping parameters from the starting geometry.
In particular, step iii) of generating a set of shaping parameters comprising at least one shape geometry parameter of the starting geometry may further comprise one or more sub-steps, such as a sub-step of providing the set of shaping parameters to at least one processor of a computer, such as of the computer on which the computer-implemented method is performed. Thus, the generating in step iii) may further comprise providing the set of shaping parameters to the processor, such as by using at least one shaping parameter generating unit, e.g. a shaping parameter generating unit of the computer.
Specifically, as used herein, the term “simulating a shaping process using the shaping tool” may refer to a process of applying at least one simulation tool to the shaping tool and/or die for the purpose of determining at least one adapted set of shaping parameters. In particular, simulating a shaping process using the shaping tool may comprise iteratively varying values of the set of shaping parameters and determining for each value of at least one shaping parameter at least one simulated shaping property of the shaping tool. Further, the at least one simulated shaping property may be compared with at least one shaping target criterion of the set of shaping target criteria, in order to determine the values of the set of shaping parameters for which the shaping tool fulfills, at least within predetermined tolerances, the set of shaping target criteria. As an example, the purpose of simulating the shaping process using the shaping tool may specifically be or may comprise generating at least one adapted set of shaping parameters, for example identifying at least one form or shape for the shaping tool, for which the shaping target criteria are fulfilled. In particular, as outlined above, the simulating may be or may refer to a process of optimizing.
Thus, the term simulating a shaping process using a shaping tool may specifically be or may comprise a process of optimizing a shaping process.
As used herein, the term “varying values of the set of shaping parameters”, may refer to a process of changing a value of at least one shaping parameter of the set of shaping parameters, which may specifically be performed iteratively. In particular, the values of the set of shaping parameters may be varied by following a preset and/or a predetermined pattern or protocol. Alternatively, the values of the set of shaping parameters may be varied randomly.
In particular, simulating the shaping process, specifically in step iv), as outlined above, may be or may comprise an iterative process, specifically an optimization process. Thus, as an example, when simulating the shaping process using the shaping tool, specifically in step iv), the set of shaping parameters of the starting geometry, such as the values of a set of variables determining at least one characteristic or behavior of the starting geometry for the shaping tool, may be changed and/or varied, e.g. randomly and/or by following one or more predetermined patterns. These changed parameters, e.g. the changed and/or varied values of shaping parameters, when simulating the shaping process in step iv), may then be analyzed, e.g. subsequently, in order to determine whether or not for these changed shaping parameters the shaping tool fulfills the set of target criteria, e.g. falls within predetermined tolerances of the target criteria. Again, as outlined above, this procedure may be performed iteratively, such as in case the shaping target criteria are not met, e.g. as is commonly known in optimization procedures. As an example, if the shaping tool having the geometry of the changed and/or varied shaping parameters, e.g. of the changed and/or varied values of the set of shaping parameters, does not fulfill the set of shaping target criteria, the shaping parameters, e.g. the values of the set of shaping parameters, may again be changed and/or varied. Thus, as outlined above, e.g. in the previous paragraph, when simulating the shaping process using the shaping tool in step iv), the varying of the values of the set of shaping parameters may specifically be performed iteratively, e.g. until a set of shaping parameters, specifically values of the set of shaping parameters, are such that the shaping process using the shaping tool fulfills the set of shaping target criteria, at least within predetermined tolerances.
As used herein, the term “simulated shaping properties”, may refer to at least one value and characteristic to be expected of a simulated object and/or process. Thus, the simulated shaping properties, specifically the simulated shaping properties of the shaping tool, may for example be or may comprise at least one value and/or characteristic of the shaping tool to be expected when using the shaping tool in the shaping process. In particular, the simulated shaping properties of the shaping tool may comprise at least one expected value of the shaping tool when using the shaping tool in the shaping process, in case the geometry of the shaping tool used in the shaping process equals a simulated geometry shaping tool and a simulated shaping process. Specifically, the simulated shaping properties, for example, may be or may comprise at least one expected value of the shaping tool in case the geometry as described by the values of the set of shaping parameters used in the simulation equals the simulated geometry.
As used herein, the term “adapted set of shaping parameters”, may refer to at least one set of values describing the shaping tool, e.g. the geometry of the shaping tool, for which the shaping target criteria are fulfilled at least within predetermined tolerances. Thus, the adapted set of shaping parameters may specifically be or may comprise at least one outcome of simulating the shaping process using the shaping tool. In particular, in step iv), the set of shaping parameters may be adapted by comparing simulated shaping properties, such as simulated characteristics or specifications, for varying values of the set of shaping parameters with the set of shaping target criteria. Thus, an adapted set of shaping parameters may be generated, for which the shaping target criteria are fulfilled at least within predetermined tolerances.
In other words, the adapted set of shaping parameters may specifically refer to an adapted set of values of shaping parameters. Thus, the adapted set of shaping parameters, e.g. the set of adapted values of shaping parameters, may specifically refer to a set of adapted shaping parameter values for which the shaping target criteria are fulfilled, e.g. at least within predetermined tolerances.
In particular, in step iv), the set of shaping parameters may be adapted by comparing simulated criteria, such as simulated characteristics or specifications, for varying values of the set of shaping parameters with the set of shaping target criteria. Thus, an adapted set of shaping parameters may be generated, for which the shaping target criteria are fulfilled at least within predetermined tolerances. The term “the shaping target criteria are fulfilled at least within predetermined tolerances” refers to the fact that the shaping target criteria are completely fulfilled wherein deviations are possible within the predetermined tolerances. In detail, the adapted set of shaping parameter as generated in step iv) may define a geometry of the shaping tool for which the shaping target criteria may be fulfilled or achieved, wherein an optimum may be missed so long as a discrepancy or deviation is smaller than the predetermined tolerances. As an example, the shaping target criteria may be considered being fulfilled so long as an optimum or maximum fulfillment of the shaping target criteria may be reached. Specifically, the target criteria may be fulfilled so long as a maximum or minimum, for example a global maximum or a global minimum, of at least one shaping target criteria is reached. Thus, the shaping target criteria may be considered to be fulfilled or achieved so long as a minimum discrepancy and/or a minimum deviation is reached. Additionally or alternatively, the shaping target criteria may be fulfilled at least within predetermined tolerances as long as a difference or discrepancy between the simulated criteria and the shaping target criteria is smaller to or equals the predetermined tolerances. Specifically, the shaping target criteria may be considered to be fulfilled so long as the simulated criteria and the shaping target criteria differ from each other by no more than 50%, preferably by no more than 20%, more preferably by no more than 10%.
The starting geometry may specifically be a negative geometry of the at least one lead candidate geometry, designed by using the computer-implemented method for designing at least one shaped body, as described above or as will be described in further detail below. Thus, for possible definitions of terms used herein, reference may be made to the description of the computer-implemented method for designing at least one shaped body as disclosed in the first aspect of the present invention.
The shaping target criteria may specifically comprise at least one suitability of the shaping tool for shaping at least one predetermined object. Thus, at least one shaping target criteria of the set of shaping target criteria may be or may comprise the at least one suitability of the shaping tool for shaping at least one predetermined object. The predetermined object may, for example, be or may comprise the shaped body designed by using the computer-implemented method for designing at least one shaped body, as described above or as will be described in further detail below. Thus, as an example, at least one shaping target criteria may be or may comprise the suitability of the shaping tool for shaping the shaped body.
The set of shaping target criteria in step i) may, for example, be retrieved via at least one interface, specifically via at least one web interface. Additionally or alternatively, the at least one geometry of the shaping tool may be output via the at least one interface.
The shaping target criteria may specifically contain at least one constraint selected from the group consisting of: a surface property constraint; a geometry constraint, specifically a geometry constraint of an object to be shaped by using the shaping tool; a pressure constraint; a shear force constraint; a compaction force constraint; an ejection force constraint; a die-filling constraint; a productivity constraint; an economic constraint, e.g. a price and/or a profit margin; a force distribution constraint; a velocity distribution constraint; a mechanical stability constraint; a strength constraint, such as a tensile strength constraint; a pore size constraint; a weight constraint; an attrition performance constraint; a production machine constraint, e.g. a dimension of the production machine; a production constraint, e.g. a limitation for the design due to the production technology.

As an example, the simulation unit 160 may be configured for simulating the shaped body 112. In
In particular, when designing at least one shaped body 112 with the designing system 152, a seed geometry may be described, for example, with geometric parameters. Further, the geometry defining unit 156 may be used for defining the seed geometry, e.g. a generated geometry. The seed geometry may then be evaluated by using the simulation unit 160 for performing simulations according to pre-defined performance criteria, such as by varying values of the set of parameters and by comparing simulated criteria for these values with the set of target criteria until an adapted set of parameters is generated for which the target criteria are fulfilled. In detail, as an example, according to the result of the comparison, the values of the set of parameters, e.g. the geometric parameters, may be varied in the simulation, e.g. during an optimization loop, in a way that firstly a new geometry may have a higher probability of fulfilling the pre-defined criteria, e.g. the target criteria, and secondly may reduce simulation resources and time. In particular, the optimization loop may be conducted until a best possible compromise among targets may be reached, wherein further target criteria, such as boundary conditions may be respected.
The target criteria may, for example, comprise constrains of geometry and weight. Thus, the target criteria may comprise pre-existing constrains of geometry, e.g. dimensions of existing shaping machines or existing application reactors, and weight, e.g. pre-existing constrain of a maximum and/or minimum weight inside application reactor. Further, the target criteria may, for example, comprise constrains of surface area, weight and density. Thus, the target criteria may comprise the geometric external surface area or weight of a single shaped body, the specific surface area of a single shaped body, e.g. a surface area divided by weight or its reciprocal, the surface or weight of the particles within reactor bed, the specific surface area of a reactor bed, e.g. a surface area of bed of shaped body divided by volume of empty reactor or its reciprocal, the loading density of a reactor bed, e.g. a weight of bed divided by surface area of bed or its reciprocal. Specifically, the target criteria may further include a BET surface area of a single particle or of the reactor bed, and/or the internal surface area of a single particle or of the reactor bed. Additionally or alternatively, the target criteria may include a pore structure of the shaped body or particle or of particles within the reactor bed.

Thus, the target criteria may comprise a pressure drop of a shaped body, specifically of a single shaped body and/or reactor bed, such as a reactor bed filled with shaped bodies. In particular, the pressure drop may be calculated by using, as an example, state-of-the-art mathematical correlations. Further, the pressure drop may be calculated and/or simulated by using, as an example, state-of-the-art tools such as computational fluid dynamics (CFD) and/or other methods. Specifically, the pressure drop may be calculated and/or simulated, for example, by using information on fluids and conditions, such as temperature, pressure and/or residence time, which may occur in a reactor. Additionally or alternatively, the pressure drop may be calculated and/or simulated, for example, by using estimated information on fluids and conditions. Additionally or alternatively, the pressure drop may be calculated and/or simulated, for example, by using similarity aspects, e.g. by estimating the pressure drop for similar geometries. These calculation and/or simulation approaches may, for example, allow for an absolute and/or relative comparison.
Additionally or alternatively, the target criteria may be or may comprise a heat transport, specifically a maximum and/or a minimum of heat transport. Thus, the target criteria may comprise a heat transport of a shaped body, specifically of a single shaped body and/or reactor bed, such as a reactor bed filled with shaped bodies. In particular, the heat transfer may be calculated by using, as an example, state-of-the-art mathematical correlations. Further, the heat transfer may be calculated and/or simulated by using, for example, state-of-the-art tools such as computational fluid dynamics (CFD), finite element method (FEM) and distinct element method (DEM), and/or other methods.

Additionally or alternatively, the productivity may be calculated and/or simulated by using manufacturing information, e.g. on production machines, such as production lines, and/or on product properties, e.g. product properties which may be needed to produce the desired geometry with the desired chemical composition and physio-chemical properties. Specifically, other target criteria, such as, for example, an extrusion pressure, an extrusion speed and/or a shear force upon extrusion, specifically for extrudates, and/or a compaction force, a machine rotation speed and/or an ejection force upon tableting, specifically for tablets, may be considered affecting the productivity, e.g. positively or negatively. Additionally or alternatively, the target criteria may be or may comprise any further criteria, such as for example, a technical criteria, such as a capacity of the shaped body to roll, an economic criteria, such as a market size or a market model, e.g. for a pre-determined group of geometries, a minimum and/or maximum expense, such as a production cost, e.g. a cost model for a pre-determined group of geometries.

The set of shaping target criteria may comprise a plurality of shaping target criteria, such as a first shaping target criterion Y1, a second shaping target criterion Y2, a third shaping target criterion Y3, and so on. As illustrated in
As an example, the simulation unit 178 may be configured for simulating a shaping process using the shaping tool 126. In
In particular, when designing at least one shaping tool 126 with the shaping tool designing system 170, a starting geometry may be described, for example, with geometric parameters. Further, the geometry defining unit 180 may be used for defining the starting geometry, e.g. a shaping tool geometry. The starting geometry may then be evaluated by using the simulation unit 178 for performing simulations according to pre-defined performance criteria, such as by varying values of the set of shaping parameters and by comparing simulated shaping properties for these values with the set of shaping target criteria until an adapted set of shaping parameters is generated for which the shaping target criteria are fulfilled. In detail, as an example, according to the result of the comparison, the values of the set of shaping parameters, e.g. the shaping tool geometric parameters, such as the geometric parameters, may be varied in the simulation, e.g. during an optimization loop, in a way that firstly a new geometry may have a higher probability of fulfilling the pre-defined criteria, e.g. the shaping target criteria, and secondly may reduce simulation resources and time.
Specifically, when designing at least one shaping tool 126 with the shaping tool designing system 170, the properties of the material to be shaped, e.g. a density and/or a viscosity, and/or further the shaping target criteria, such as boundary conditions of the machines used for shaping, e.g. a maximum extrusion pressure and/or a minimum rotation speed of tableting machine, may be taken into consideration.
As an example, the shaping tool designing method 124, may aim at identifying the geometry of shaping tools that allows the shaping of the starting material into the desired geometry, while maintaining the targeted product properties and manufacture productivity. In particular, the shaping tool designing method 124 may be used, as an example, to determine an optimized geometry of the shaping tool, e.g. the die, specifically for new geometries of shaped bodies. Additionally or alternatively, the shaping tool designing method 124 may be used for deriving new geometries of shaping tools for existing shaped bodies.
When simulating the shaping process using the shaping tool 126, for example by using the simulation unit 178, as an example, physical properties of the material to be shaped may need to be estimated and/or measured to be used in the simulation.
The shaping target criteria may, for example, comprise a material property of the material to be shaped. Thus, the shaping target criteria may comprise a viscosity, a powder bulk density, a compressibility, e.g. a compressibility-compactability curve. Additionally or alternatively, the shaping target criteria may, for example, comprise surface properties. In particular, a surface property of the shaping tool 126 may for example directly influence a surface of an object, e.g. of the shaped body 112, manufactured by using that shaping tool 126. Thus, the shaping target criteria may be or may comprise properties of the shaped body 112. In particular, the properties of the shaped body, e.g. a geometry, a weight, a mechanical strength, a porosity or the like, may be estimated from a measured and/or calculated and/or simulated results of a use of the shaping tool 126, e.g. as a shaping tool. Additionally or alternatively, the shaping target criteria may comprise boundary conditions of manufacturing machines, such as a machine geometry, a maximum allowed pressure, a maximum allowed shear force, a maximum allowed compaction force and/or a maximum allowed ejection force.
Additionally or alternatively, the shaping target criteria may be or may comprise a productivity, specifically a minimum and/or a maximum productivity. The productivity may specifically be estimated by using existing data of similar geometries. Additionally or alternatively, the productivity may be calculated and/or simulated by using manufacturing information, e.g. on production machines, such as production lines, and/or on product properties, e.g. product properties which may be needed to produce the desired geometry with the desired chemical composition and physio-chemical properties. Specifically, other shaping target criteria, such as, for example, an extrusion pressure, an extrusion speed and/or a shear force upon extrusion, specifically for extrudates, and/or a compaction force, a machine rotation speed and/or an ejection force upon tableting, specifically for tablets, may be considered affecting the productivity, e.g. positively or negatively. Additionally or alternatively, the shaping target criteria may be or may comprise any further criteria, such as for example, a technical criteria, such as a capacity of the shaped body to roll, an economic criteria, such as a market size or a market model, e.g. for a pre-determined group of geometries, a minimum and/or maximum expense, such as a production cost, e.g. a cost model for a pre-determined group of geometries. In particular, the productivity may be influenced by a geometry of the shaping tool, e.g. of the die, and may thus influence its design.

As an example, the illustration of step VI) 150 may show that information may flow from one step to another, such as between any one of steps I) 140 to V) 148. Additionally or alternatively, information could be centralized, such as in a common data lake, wherein information from any of one of steps I) 140 to V) 148 may be centralized and any one of steps I) 140 to V) 148 may be able to access said information. In particular, the information transfer and/or exchange, as illustrated in
Specifically, step III) 144, step IV) 146 (not illustrated) and step V) 148 may be performed individually and/or in combination with each other or in combination with step I) 140 and/or step II) 142. The method 138 for designing a manufacturing process for manufacturing at least one shaped body 112 may be initiated at any one of steps I) 140, II) 142, III) 144, IV) 146, V) 148 or VI) 150. In particular, each of the steps I) to VI) may provide a usable output.
As an example, the method 138 for designing a manufacturing process for manufacturing at least one shaped body 112 may be applied to shaped bodies such as tablet, extrudate, honeycomb, three-dimensional printed bodies, particles, or any other two-dimensional or three-dimensional structures. The method 138 for designing a manufacturing process for manufacturing at least one shaped body 112 may specifically be configured for designing a manufacturing process for manufacturing a catalyst geometry. However, the method 138 for designing a manufacturing process for manufacturing at least one shaped body 112 may be applied for designing, e.g. optimizing, the geometry of any two-dimensional or three-dimensional object or body.

Further, input information, such as general input information, for step III) 144, e.g. an input information from a need owner into step III) 144, for example, may be or may comprise one or more of: a boundary condition for the shaping tool 126, e.g. of at least one die, e.g. the geometry of the shaping tool 126; a prototyping information, e.g. a pressure; a requirement, such as a material requirement, e.g. for minimizing a corrosion. An output information from step III) 144, e.g. an output information from step III) 144 to a need owner, for example, may be or may comprise one or more of: the shaping tool 126, e.g. a prototyped die; a technical documentation, such as a technical drawing and/or a technical model.
Further, input information, such as general input information, for step V) 148, e.g. an input information from a need owner into step V) 148, for example, may be or may comprise one or more of: a material information, specifically a material combination, e.g. a material recipe, such as a recipe to be tested: a mechanical information on the shaped body and/or on the shaping tool, specifically a stability of the catalyst; an information on a sensitivity of the shaped body and/or of the shaping tool to production parameters; information on which experiments have been conducted; information on analytic parameters, specific on required analytical parameters; information on the safety aspect of at least one experiment. An output information from step V) 148, e.g. an output information from step V) 148 to a need owner, for example, may be or may comprise one or more of: a behavior upon shaping the shaped body 112 with the shaping tool 126, e.g. an extrusion pressure versus a speed; an evaluation of the shaped body 112 and/or the shaping tool 126, e.g. of the optimized geometry, such as an evaluation of the optimized geometry using analytic parameters.
In particular, the manufacturing process for manufacturing at least one shaped body 112 may be configured for fulfilling at least one need. In particular the need may, for example, be a combination of the target criteria of the designing method 110 and the shaping target criteria of the shaping tool designing method 124.
In particular the at least one need to be fulfilled by the manufacturing process for manufacturing at least one shaped body 112 may be considered in the manufacturing process designing method 138. Thus in particular, the need, e.g. a combination of the target criteria and the shaping target criteria, may be identified based on at least one consideration of one or more of: a technology available for the manufacturing process; a cost, such as a production cost for the shaped body 112 and/or for the shaping tool 126; a market. In particular, the target criteria may be or may comprise one or more of: a maximum and minimum allowed pressure drop; target productivity in tons/day; or the like. Specifically, the shaping target criteria may be or may comprise one or more of: a maximum allowed extrusion pressure; maximum allowed rotation speed of tableting machine; or the like. Further, both the target criteria and the shaping target criteria, for example a boundary condition for the simulations and optimizations, of step I) 140 and step II) 142, may further be relevant for performing step III) 144 and may specifically be or may comprise one or more of: an extrusion constraint, such as a maximum diameter of extrusion die; a tableting constraint, such as a maximum tablet height; a shaping constraint, such as a genera boundary of the shaping process.
As an example, a designing of the manufacturing process may specifically depend on the target criteria for the shaped body 112, such as on at least one required property of the shaped body. In particular, a geometry, e.g. a shape, and/or a material of the shaped body may determine the selection. In particular for complex shapes, new manufacturing technologies, such as for example, additive manufacturing, may be used. Dependent on the application, as an example, the additively manufactured parts may receive a finishing, such as a final treatment in order to smoothen the surface of the part. Thus, in case the shaping tool 126 may be prototyped or manufactured by using an additive manufacturing process, its surface may receive a finishing, e.g. a treatment in order to smoothen the surface. As an example, for finishing the surface of the shaping tool 126 one or more of the following technologies may be used: Electro Polishing, Plasma Polishing, Laser Polishing, Tumbling, Blasting, Hydro Erosive Grinding and MMP (Micro Machining Process).
