The present invention relates to an article of sports apparel being optimized for a data profile and to a method of manufacturing such an article of sports apparel, e.g., footwear.
Articles of sports apparel such as shoes are usually manufactured as ready-made, mass-produced finished products. They are usually not custom tailored according to measurements, but rather generalized according to anthropometric studies. Thus, athletic shoes are generally made with a single tread pattern, not optimized for a particular individual's needs or to a specific data profile, but with an approximation of the activity and aesthetic considerations (e.g., trail running shoes may have larger lugs and more traction elements than running flats, but neither are informed by objective and customized data).
In professional and ambitious amateur sports, it is known to customize sports apparel up to a certain point. Such customization is often done based on a static analysis, e.g., length and size measurements of the athlete's body. Based on those measurements, customized sports apparel, for example a soccer shoe is then manufactured.
Dynamic analyses are rare. An athlete may be equipped with one or more sensors which are, e.g., attached to one or more of the athlete's limbs while engaged in a typical athletic activity. Video analysis of the athlete engaging in the athletic activity may also occur—a video of the athlete can be recorded and analyzed. For example, a runner may be filmed while running on a treadmill. An orthopedically trained person may then extract information (e.g. supination and pronation) from the filmed video which is then used for manufacturing a customized running shoe having particular cushioning, etc.
However, the mentioned techniques for customizing sports apparel may have disadvantages if used in isolation. These techniques generally require personnel trained in sports medicine and/or orthopedics. And these techniques do not account for traction customization. As such analyses are usually performed during a limited amount of time, they do not show long-term evolution of the athlete's performance characteristic and are prone to day-to-day variations in such performance characteristics—much less variation in the equipment over time, such as a tread wear pattern. Furthermore, as they are generally performed in a laboratory-like environment, such analyses do not provide any context information, i.e. information about the environment in which the athlete typically performs sports activities.
An objective then is producing an article of sports apparel, e.g., a shoe, that is customized for a person, or optimized to a particular data profile, at moderate additional manufacturing costs taking into account long-term variations in performance characteristics and environmental information. Particular advantages can be obtained when providing for individualized traction customization or optimization.
This objective is met by the sports apparel (e.g., shoe) being customized for a person, or optimized to a particular data profile, wherein the sports apparel is manufactured based on an individual profile built based on received sensor data. In other embodiments, the apparel is manufactured based on a profile built from data for more than one person. In still other embodiments, the data may be obtained not from a person, e.g., from a robotic test machine but by other testing and data collection means. The sensor data may include data related to traction, pressure, gait feedback, etc. Additionally, specific data related to an individual's particular movement (e.g., specific activity-related movements) may also inform the sensor data and be integrated into the individual profile. Once the individual profile is created, it may be translated onto a variety of digital geometries (e.g., outsole geometries) such that a customized digital model is created. The digital model, such as an outsole model, may then be translated into machine language to form a physical outsole for use in a finished custom article.
Deriving pressure data from an individual is also known. However, utilizing light intensity and transforming it into data to accurately determine a wearer's pattern of performance, whether it's banking and cutting in basketball, or sprinting 100 yards, is something that has not been perfected.
Indeed, algorithmic solutions disclosed herein may be used such that a data driven input may produce a digital outsole that can be then translated into a physical outsole, with a customized physical traction pattern is based on at least in part a computational traction profile. In this way, sensor and research data on loading profiles for varied running and sports movements (e.g., linear & multidirectional movements) may be applied to produce customized outsoles with improved traction characteristics. For example, data related to direction and magnitude vectors of force or pressure may be applied to alter a digital visual traction pattern in response to the construction of a computational traction profile based on received and analyzed data.
In recognizing that aesthetics may be important to an individual, a novel design of a visual outsole, such as a visual outsole pattern created in a three-dimensional space may be created with attention given to aesthetic and artistic elements. These aesthetic and artistic elements may take the form of traction elements such as projections, protrusions, recesses, apertures, lugs, and other surfaces or features of an outsole. Once a computational traction profile is produced it may be used to alter these aesthetic artistic elements such that they are functionally improved for particular use (e.g., giving the outsole to be produced a more optimized traction characteristic across the outsole). In some embodiments, a visual outsole may not be required, and only data may be required to produce a physical outsole.
The digital representation of an outsole (e.g., a visual outsole pattern) may be used to run simulations or open molds and testing prior to production. The visual outsole pattern may be manufactured the one or more manufacturing processes, such as laser cutting, 3-D printing, 3-D molding, etc.
A full digital model may be a three-dimensional model of the apparel (e.g., complete shoe including midsole, insole, upper, last, etc.) including a functional description. The functional description can include information such as which materials are used, where materials are placed, which sensors are used and where sensors are placed, etc.
The accompanying figures, which are incorporated herein, form part of the specification and illustrate embodiments of the present invention. Together with the description, the figures further serve to explain the principles of and to enable a person skilled in the relevant arts to make and use the invention.
The present invention will now be described in detail with reference to embodiments thereof as illustrated in the accompanying drawings. References to “one embodiment”, “an embodiment”, “an example embodiment”, “some embodiments”, etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.
The term “invention” or “present invention” as used herein is a non-limiting term and is not intended to refer to any single embodiment of the particular invention but encompasses all possible embodiments as described in the application.
Various aspects of the present invention, or any parts or functions thereof, may be implemented using hardware, software, firmware, non-transitory tangible computer readable or computer usable storage media having instructions stored thereon, or a combination thereof, and may be implemented in one or more computer systems or other processing systems.
As described above, deriving pressure data for an individual is known, for example with instrumented insoles. However, utilizing light intensity and transforming it into data to accurately determine a wearer's pattern of performance, whether it's banking and cutting in basketball, or sprinting 100 yards, is something that has not been perfected. The inventors have provided improved systems and methods related to generating an outsole pattern—and manufacturing said outsole pattern—based on a wearer's profile using a wearer's pressure data and/or step profile.
The phases of the system and process are described herein—initially, an individual's movement pattern is used to generate a profile for the individual. This entails measuring and analyzing a wearer's movement pattern, for example using sensor modules. Specifically, traction-specific sensor modules may be used, such as a sensor module using a frustrated total internal reflection (“FTIR”) system. A computational traction profile may be generated based on data from the FTIR system. Once generated, the computational traction profile may be used to generate and/or optimize a visual outsole pattern (e.g., in a 3-D CAD or CAM system).
The visual outsole pattern may be based on at least one characteristic from the individual's profile. For example, parametric modeling may be applied such that the computational traction profile may adjust a shape, size, or number of traction elements to be applied to a visual outsole pattern. Once generated or optimized, the custom visual outsole pattern may be translated into a machine language for manufacturing. In this way, the visual outsole pattern may be used to manufacture the physical outsole pattern.

During data capture, individual 100 may perform one or more movements on the surface of sensor module 102. These movements may include, but are not limited to, running, sprinting, walking, banking, cutting, lunging, squatting, side-stepping, balancing, exercise movements, pronation and supination, foot strike profiles, and hard stop movements. In some embodiments, the movements may correspond to sports specific activities. For example, in the context of basketball, individual 100 may perform game related movements for data capture, such as shooting free throws, jump shots, driving a lane, jump stops, and pivoting.
As shown in
Other movements are contemplated, specific movements such as drives, catching and shooting a ball, picking-and-rolling, off-the-ball screen, pull-up jumper, rebound, etc. In some embodiments, sensor module 102 may be configured as a playing surface for an activity. In some embodiments, sensor module 102 may be embedded in an article of athletic apparel, such as a shoe. Individual 100 may perform movements in a lab setting. In some embodiments, individual 100 may perform movements in an athletic activity setting, for example a sports-specific activity such as a game. Weighting factors 112 may be applied, for instance to denote relative importance of a particular movement to be factored into the computational traction profile of the individual.
When individual 100, or an article worn by individual 100, such as a shoe, makes contact with sensor interface surface 108, the total internal reflection is frustrated at interface zone 122. Based on the data captured by infrared camera 116 coupled with the principle of critical angle index reflection, the data may be processed to provide a relative profile that may correlate with a gradient pressure map of contact area over a given time when multiple images are captured by infrared camera 116. Examples of such data being captured can be found in
The frustrated internal reflection occurs when light travels from a material with a higher refractive index in the direction of a lower refractive index at an angle greater than its critical angle. It becomes “frustrated” when a third object comes into contact with the surface and alters the way the waves propagate, and the capture of which may be used to produce a surface pattern. FTIR is able to detect contact area at a very high resolution through image processing. Through software, measured light intensity can be sorted into a gradient of high to low intensity pixels, yielding a measurement of relative pressure. The light intensity data may thus be correlated with traction characteristics of an outsole.
Images captured by camera 116 may be analyzed by a data system 200, further described with reference to
In some embodiments, sensor module 102 may be one or more separate sensors. For example, an instrumented insole (such as those made by Pedar ®) may be provided in addition to or as a replacement for an FTIR system. In any case, athlete movement data may be collected, such as plantar pressure distribution data during movements related to that athlete needs. In some embodiments, it can be compared to and used with previous data captured. Types of data which may be analyzed include but are not limited to force, plantar pressure distribution, and direction of movements, such as but not limited to angle and/or magnitude. These movements may correlate with common sports movements.
In some embodiments, on-field/in-game data may be acquired separately from any FTIR analysis. Data acquired by sensor module 102 is used to determine the location of a relative need of traction based on movement requirements and frequency. In some embodiments on-field data may be collected such that various movements are quantified, e.g. by counting which movements are done most often during a game. In this way replication of those movements may be performed within FTIR system not during a game to gather more accurate data. By counting which movements are done most often, key variables may be weighted (e.g., maximum plantar pressure data), and input to produce a computational traction profile that is used in the generation of a visual outsole pattern. Additional examples of techniques that may be used are described in commonly owned U.S. patent application Ser. No. 13/543,428, filed Jul. 6, 2012, now U.S. Pat. No. 9,317,660, Ser. No. 13/797,361, filed Mar. 12, 2013, now U.S. Pat. No. 9,500,464, Ser. No. 15/016,665, filed Feb. 5, 2016, now U.S. Pat. No. 9,802,080, and Ser. No. 15/716,171, filed Sep. 26, 2017 and published as U.S. 2018/0015329, each of which are incorporated by reference herein for all purposes.
FTIR systems and other optical contact area measurement systems may be used and disclosed systems and methods. Other mechanical traction tests may also be applied in creating a customized computational traction profile, such as the use of force plates, potentially integrated into an FTIR or other optical systems. Other methods, such as slip imaging using high frame rate image subtraction techniques, dynamic center of pressure mapping to better understand loading over time, edge analysis quantifying the number of edges in contact at a given time, and optical shear measurement may also be data input into data system 200 to create the computational traction profile.

In some embodiments, collecting a computational traction profile may include obtaining previously collected and stored data for an individual. In some embodiments, a standard profile for individuals having a certain shoe size, weight, height, arch shape, stability characteristic, and/or touchdown characteristic may be retrieved and then customized based on data obtained through sensor module 102.
In some embodiments, computational traction profiles 600 may be one or more maps generated based on data collected for an individual. In some embodiments, computational traction profiles 600 may be customized profile maps for a group of individuals. For example, computational traction profiles 600 shown in
Computational traction profile 600 may include various stress areas 602 associated with a particular individual 100. Computational traction profiles 600 may include various stress areas 602 associated with different groups of individuals, based on information from sensor module(s) 102. For example, as shown in

As illustrated in
In order to be able to measure the angle of the outsole at the point of time when the heel hits the ground 33, the running shoe 31 may be equipped with an accelerometer and a gyroscope. Data from the accelerometer allows to determine the impact of the heel on the ground, whereas data from the gyroscope allows to determine the orientation of the shoe during such impact.
Typically, ground contact time can give the runner a feedback about his running style. Based on the ground contact time it also possible to derive, possibly based on a calibration, the speed, distance, and/or pace of the person. These parameters can be used to let the person know when the shoe is worn out or to provide the person with performance data, like speed, distance, pace, etc. Furthermore, during times of no contact with the ground, a processor in the shoe may be put into sleep mode, and battery power can be conserved.
These parameters may inform the type of friction element to be used in an outsole. These friction elements may be applied during the generation of the computational traction profile, which in turn is used to generate a visual outsole pattern, and finally a physical outsole. Turning to

Taken together, computational pressure matrix 904 includes a plurality of different zones located, sized, and shaped to provide desired characteristics. The zones may be correlated to a particular traction pattern and may be made from one or more elements. Once a computational traction profile is obtained and built using data from sensor module 102, a visual outsole pattern is generated based on the profile. The visual outsole pattern may be generated using computer modeling program such, as but not limited to Grasshopper 3D, Rhinoceros 3D, Modo 3D CAD software or the like.
Data system 200 may receive data from sensor module 102, for example FTIR data. This data may be captured and stored for analysis by data system 200. Data system 200 may utilize computational pressure matrices or pressure map, and data from sensor module 102 in order to create a customized computational traction profile. In this way, measuring and analyzing an individual's movement pattern can be applied to the creation of the visual outsole pattern, further optimizing an outsole produced for a particular traction profile.
Data system 200 may evaluate data from sensor module 102. For example, the sensor module 102 data may be preprocessed to remove noise, identify particularly relevant sections of the sensor data corresponding to sports activities, etc. To this end, techniques of preprocessing, digital filtering, feature extraction, statistical processing, machine learning, etc. may be used. In the case of using additional data outside of FTIR or other optical methods, data system 200 may also derive information from the sensor module 102 data such as usage (e.g. lifetime distance) of the previous product (e.g. shoe), average speed on a run, difference in altitude, average pace of the shoe, maximum speed, temperature in the product (e.g. shoe) or on the skin of the person, pressure points within the product (e.g. shoe), etc. System 200 may include components such as a processor, microcontroller, ASIC, DSP, etc., to carry out such processing and analysis, or the analysis may be performed on a different device, e.g. a server, desktop computer, cloud server, etc. In the latter case, the sensor data may have been transmitted to the different device as described above.
Data translation system 300 may receive processed data from data system 200, including a computational traction profile. Then, data translation system 300 may generate or optimize a visual outsole pattern. As described above, the visual outsole pattern may be generated using computer modeling program such, as but not limited to Grasshopper 3D and/or Rhinoceros 3D CAD software. In some embodiments, the software is used to translate and convert the data to geometries for outsole patterns. In some embodiments images may be converted to a color image, for example an RGB image. In this way colors may correspond to estimated force, pressure, service area values, etc. data may be translated via the images brightness, for example converting the RGB values into a single value. Data translation system 300 may then use these values to generate, or optimize, local elements of a visual outsole pattern. In this way, particular elements may be shaped, sized, and placed according to local optima for traction purposes.
Machine instructions may be provided by data translation system 300, or manufacturing system 400. In this way, a physical outsole may be produced based on generated visual outsole pattern provided by data translation system 300. Manufacturing system 400 may include machine instructions, and/or manufacturing components required for producing a physical outsole based on the optimized computational traction profile. Several different manufacturing methods are contemplated and may be used alone or together to create a physical outsole. In some embodiments, outsole pattern may be molded onto a block outsole blank. In some embodiments, laser-cutting or etching may be used such that slip-like patterns may be cut into a block outsole blank. In some embodiments, thermo-molding or similar processes may be used to create the physical outsole. In the case of thermo-molding, the outsole may be molded on a relatively flat surface, or three-dimensional form such as a last. In some embodiments, an outsole may be 3-D printed. Additional examples of manufacturing techniques that may be used are described in commonly owned U.S. patent application Ser. Nos. 15/156,062, filed May 16, 2016 and published as U.S. 2017/0325545, Ser. No. 15/156,104, filed May 16, 2016 and published as U.S. 2017/0325546, Ser. No. 15/470,570, filed Mar. 27, 2017 and published as U.S. 2018/0271213, Ser. No. 15/898,000, filed Feb. 15, 2018 and published as U.S. 2018/0271211, and Ser. No. 15/588,433, filed May 5, 2018 and published as U.S. 2018/0317606, each of which are incorporated by reference herein for all purposes.
At this time a decision may be made as to whether a new outsole is desired and if so revert back to one or more of the previous method steps 1102, 1104, 1106, or 1108. So, if updates or refinements to the outsole are required new updates and changes can be made in a new outsole produced. In some embodiments, a finished product such as a shoe may be produced having a custom outsole based on the computational traction profile as well as an instrumented insole, for example pressure sensitive insole that may measure or augment pressure mapping data during use. In some embodiments, this data may be fed into the method 1100 at one or more points along the method steps.
In some embodiments, the base type of outsole may be selected by an individual for production. For example, the standard traction profile may be selected based on factors including but not limited to type of sport/activity, type of foot profile, body type, weather, environment, type of surface, type of outsole material, type of footwear, type of manufacturing, gait characteristics, degree of waterproofness desired, mechanical load requirements, thickness, size, weight, etc. Once the standard traction profile selection has been made to produce a customized outsole, the computational traction profile may be used to customize the visual outsole pattern. In some embodiments, the shape, design, dimensions of the traction profile, etc., and are manipulated based on the received data within the computational traction profile.
In some embodiments, the outsole is formed from a material that may be cut, e.g., laser cut, such as rubber, thermoplastic polyurethane (TPU), polymeric materials, and the like. In this way, an outsole blank may be produced having general contours of footwear, without any traction pattern cut into them. Once the computational traction profile is produced in step 1104 and a visual outsole pattern is created at step 1106, the pattern may be laser cut into an outsole blank, thus producing a finished outsole. In some embodiments, additional testing (e.g., FTIR testing, biomechanical testing, or mechanical testing (e.g., wear life of the produced outsole) may be conducted. In some embodiments, results can be compared to prior studies or based on new criteria—for example the use of in-shoe measuring devices such as instrumented insoles in order to evaluate the effectiveness of the finished outsole having the custom traction pattern.
In some embodiments, based on testing with a created physical outsole, treatments may be made to traction pattern by feeding data into method steps 1102, 1104, 1106, or 1108. Once improvements are made, the same physical outsole may be recut, e.g. via a laser cutting process. In this way, the custom computational traction profile may take advantage of and incorporate new information from data collected, may change relative weighing of variable importance, and may investigate additional, new variables for testing and incorporation into the computational traction profile. In this way, individualized outsoles may be produced and improved upon. Indeed, the traction patterns produced by the systems and methods disclosed herein may achieve higher degrees of traction for particular movements than otherwise possible with traditional outsole design.
Advantageously, through this operation no new mold need be created. Testing, optimization, and production of the finished outsole, or even finished article of footwear, may be completed for example at a point-of-sale location such as a retail store. This simplifies the supply chain and decreases shipping costs, e.g. overseas shipping. Additionally, embodiments that use laser cutting to produce the outsoles, environmental gains are possible in that as the outsole begins to wear down an individual may take the outsole to the manufacturing location (or otherwise ship it to the manufacturing location) and this sole traction pattern may be recut, without using a new, fresh outsole blank. Other methods of cutting that may provide similar advantages include water cutting, knife cutting, and needle cutting.
In some embodiments, the pattern of the tread may be adjusted to account for variables such as areas of high wear, high traction requirements, directional loading requirements (e.g., athlete needs), etc. In response to these variables changing, features of a particular visual outsole pattern may be adjusted. For example, traction elements may be raised, lowered, changed in size, and changed in shape. Moreover, the thickness of a given region of an outsole may be adjusted, for example to reduce abrasion. These and other varying features are described further with reference to
With reference to
In some embodiments, selection of the outsole is based at least in part on received sensor data obtained by at least one sensor module 102. Individual 100 may select an existing sole material (such as EVA, eTPU, ePEBA, TPU). As described above, various parameters may be used to suggest which type of outsole blank or standard outsole to begin with, prior to customizing a physical outsole using the custom computational traction profile to create the visual outsole pattern. For example, if the person is outdoors most of the time, an outdoor outsole may be pre-selected. If the person is indoors most of the time, an indoor outsole may be pre-selected. If the shoe is exposed to a lot of water a waterproof/water resistant outsole may be pre-selected. If the person is a forest runner, a thin outsole may be pre-selected as forest ground is flexible. If the person is a street runner, a thick outsole may be pre-selected as resilience is required. If the person is a heel striker, the heel of the outsole may be stronger. If the exact size of the foot of the person is known the outsole can be manufactured according to this size and is not limited to traditional, discrete shoe sizes.
In some embodiments, bending of the outsole, e.g., its general stiffness may be selected based on one or more parameters. For example, whether the user is a forefoot or heel striker and whether they typically perform indoor or outdoor sports may influence the stiffness of the outsole. The bending of the shoe may be adjusted by an appropriate placing of patches—for example as described in co-owned German Pat. App. DE 10 2015 224 885, incorporated in its entirety herein by reference for all purposes. In order to complete an article of footwear having a custom physical outsole, other components may be selected either automatically or through user input, such as an insole, upper, etc., each of which may be further customized to produce a custom article footwear for individual 100. As described above, additional details of component selection for a finished footwear product they be found in commonly owned U.S. patent application Ser. No. 15/416,185, filed Jan. 26, 2017, and German Patent App. No. 102016201151.0, filed Jan. 27, 2016, each of which are incorporated by reference herein for all purposes.
In some embodiments, a biometric data profile may be collected using a physiological and personal characteristic collection and analysis system. In some embodiments, the biometric data profile may be collected using the data collection and analysis system described in U.S. patent application Ser. No. 14/579,226, filed on Dec. 22, 2014 and published as US 2016/0180440, which is hereby incorporated by reference in its entirety by reference thereto.
In some embodiments, the custom apparel such as custom shoes with customized outsoles may be provided by a locker outfitter service system. For example, if the person forgot his/her sport clothes but has an urgent need for them, the locker outfitter service may deliver the needed sports clothes, in particular sports shoes, to the desired location (e.g. a gym) within a certain period of time (e.g. 8 hours). To this end, the sports clothes (for example shoes) may be produced (e.g. by using fully automated production techniques including 3D printing, placement of components by robots, knitting machines, etc.) based on a digital model that includes a custom computational traction profile in, which may be stored in a database, server, computer, or cloud for example. The shoes may for example be produced in a shop or retail store near the person's current location to minimize delivery delay. A customized sports product (e.g. apparel) according to the invention may be obtained—the product indeed may be a customized sports shoe. However, the present invention is not limited to sports shoes. Other footwear is contemplated, as well as other products that require a particular traction/friction profile.
One or more of the steps in method 1100, or system shown in
Once the visual outsole pattern is created, e.g., as a digital model in a CAD or CAM system, the outsole may be created and integrated into a custom article of footwear. The model may comprise information about which materials are used, their shape and dimensions, the kind and number of traction elements, and their placement on the outsole. In some embodiments, updating an existing digital model may be performed prior to or after manufacturing the outsole based on the computational traction profile.
In some embodiments, the individual may search in a database for existing shoe models or may get recommendations of existing shoe from the system. The parameters of the selected shoe (e.g. shape of the shoe, materials used, patch placement, etc.) may then be updated based on the sensor module 102 data obtained. In some embodiments, more than one custom outsoles may be manufactured, having a different traction pattern. However, each traction pattern may be customized using the computational traction profile that alters the visual outsole pattern.
The details for the article such as the shoe may also be customized according to the user's input. For example, the person may be asked which sensor(s) to include. Design comment such as colors, logos, etc. may also be customized. In some embodiments, functional properties may be customized (e.g. waterproofness, cushioning, etc.). In step 1108, a customized product (e.g. a shoe) is produced based on the digital model. This allows the shoe to be manufactured by partially or fully automated production techniques including 3D printing, placement of components by robots, knitting machines, weaving, braiding, etc. Such techniques are able to produce customized sports shoes at moderate costs and high throughput. Furthermore, it is possible to manufacture such customized sports shoes based on digital models not only in a factory, but also e.g. in a store. Additionally, manual methods of constructing such as an outsole or finished product such as a shoe are contemplated.
The customized sports product (e.g. shoe) obtained in step 1108 may be equipped with at least one sensor module 102, in this case a sensor module such as an instrumented insole, accelerometer, or the like. Thus, this product (e.g. shoe) may be then used in sports activities to obtain additional sensor data for a next generation of the product (e.g. a sports shoe) with further improved and customized characteristics. By this iterative process, the person may obtain a better product (e.g. sports shoe) in each generation of products (e.g. shoes). Furthermore, the products (e.g. sports shoes) may adapt to variations of the person's characteristic over time.
In some embodiments, an individual may order a sports shoe on a website of a sports equipment distributor. That individual may already have login data from a previous purchase and enters this login data, e.g. user name and password into a user interface such as a graphical user interface. The individual may be identified by his/her username or other appropriate identification information, such that client data may be loaded into one or more of a sensor module 102, data system 200, data translation system 300, and manufacturing system 400. The client data may be loaded from a database maintained by the sports equipment distributor or from a server which may be located in a cloud-based storage solution. This database may store all of the user data as described, including for example previous shoes constructed, individual computational traction profiles associated with the individual, a visual outsole patterns of previous outsoles created, and the like. This and other user data may form the basis for building the new shoe model, and physical shoe.
In some embodiments, gait cycle analysis may be performed in the shoe itself. In this case, a CPU may be integrated into the shoe which is capable of performing more advanced calculations as need by a gait cycle analysis. It is alternatively possible to store the sensor data in a memory in the shoe, transmit (e.g. via Bluetooth, BTLE, Wi-Fi, NFC, a cellular network transceiver or other transmission protocols) the sensor data to a different device (like a smartphone, table computer, desktop computer, server computer, cloud computer, etc.) and have the gait cycle analysis done there.
In some embodiments, a 3D view of the shoe model, or even simply be visual outsole pattern may be presented to the person on a display screen, for example in a window of a web browser or another suitable program (e.g., in an app running on a smartphone, smartwatch, tablet computer, digital media player, laptop computer, desktop computer or the like).
The customized article such as a sports shoe may be equipped with pronation support, supination support, or may be a neutral running shoe. Furthermore, the customized shoe can also be built with specific insole, midsole and/or outsole material, specific cushioning material in specific areas or a specific profile on the outsole, all based on the data received by sensor module 102 and adapted to the computational traction profile generated. For example, the insole may be made from a soft foam material, a stiff foam material, or a combination of both, eTPU/ePEBA material, EVA material, or any combination of several materials. Likewise, the midsole may be made from a soft foam material, a stiff foam material, or a combination of both, eTPU/ePEBA material, EVA material, or any combination of several materials. The outsole may be made from rubber having certain properties, e.g. sticky, non-marking, non-sticky, etc.). Different combinations of material and/or material properties may be used for the outsole.

In some embodiments, planar traction pattern 1200 may include recesses 1204. Recesses 1204 similarly may be organized into arrays and may be disposed protruding inward into planar traction pattern 1200. In some embodiments, recesses 1204 may be of uniform shape and/or size or may vary along planar traction pattern 1200. Recesses 1204 may vary in depth, width, and length for example. In some embodiments, various clusters of recesses may be formed in different arrangements. Recesses 1204 may be formed as slits, concave features, apertures, or through holes. In some embodiments, projections 1202 may be disposed within recesses 1204 and may provide a tooth like visual impression. In some embodiments, recesses 1204 or projections 1202 may be cut, such as laser cut, embossed, engraved, or the like.
In some embodiments, planar traction pattern 1200 may include a fin element 1208 extending from a reference plane on the surface.

As with projections 1202 and recesses 1204, fin elements 1208 may be formed in arrays, may be linear or nonlinear and structure, and may take the form of complex shapes and curves/splines across the planar traction pattern 1200. In some embodiments, the arrangement of these features may be a repeating or nonrepeating pattern along planar traction pattern 1200. In some embodiments, the pattern may be symmetric or asymmetric about a particular axis.
Certain elements of planar traction pattern 1200 may be fixed in a particular geometry or shape in some embodiments and are not altered by a generated computational traction profile in some embodiments. Alternatively, some embodiments, some or all of the elements of planar traction pattern 1200 may be altered by computational traction profile, prior to finalizing a visual outsole pattern and manufacturing the physical outsole. As used herein, “planar” may generally refer to an extended surface, and may not necessarily reflect only a flat plane, that is, the planar traction pattern 1200 may be curved, rent, angle, warped, etc. in three-dimensional space. In some embodiments, this shaping of planar traction pattern 1200 may depend in part or in whole on the computational traction profile. For example, projections may be raised in particular zones and recesses may be lowered in others, for example.
Some or all of the elements of planar traction pattern 1200 may be grouped together in different arrangements, for example a larger group of recesses 1204 may be disposed in one region as opposed to another. In some embodiments, some or all of the elements of planar traction pattern 1200 may be interconnected to form a continuous pattern. In some embodiments, some or all of the elements of planar traction pattern 1200 may be intermittent. Some embodiments one or more continuous patterns may be formed from some or all of the elements planar traction pattern 1200. One or more of the elements of planar traction pattern 1200 may be formed from various polygon shapes. In some embodiments, the frequency of the elements disposed on planar traction pattern 1200 may vary along the surface of planar traction pattern 1200.
Some or all of the features in each traction profile shown in the figures, including those shown in whole or partial outsole embodiments, may be applied in each of the other figures without limitation. For example, features, elements, and properties discussed with reference to planar traction pattern 1200 may be used in planar traction pattern 1300, or in outsole 1600, for example.

In this document, the terms “computer program medium” and “computer usable medium” are used to generally refer to media such as removable storage unit 2918, removable storage unit 2922, and a hard disk installed in hard disk drive 2912. Computer program medium and computer usable medium may also refer to memories, such as main memory 2908 and secondary memory 2910, which may be memory semiconductors (e.g. DRAMs, etc.).
Computer programs (also called computer control logic) are stored in main memory 2908 and/or secondary memory 2910. Computer programs may also be received via communication interface 2924.

Embodiments of the inventions also may be directed to computer program products comprising software stored on any computer useable medium. Such software, when executed in one or more data processing device, causes a data processing device(s) to operate as described herein. Embodiments of the inventions may employ any computer useable or readable medium. Examples of computer useable mediums include, but are not limited to, primary storage devices (e.g., any type of random access memory), secondary storage devices (e.g., hard drives, floppy disks, CD ROMS, ZIP disks, tapes, magnetic storage devices, and optical storage devices, MEMS, nanotechnological storage device, etc.).
Additionally, in addition to optical sensors such as FTIR systems, sensor modules 102 may be embodied as sensors 50 and 500, shown in
The sensor device 50 in the example of
To transmit the sensor data, results of a gait cycle analysis, etc. from the shoe to another device for creating a digital model of a customized shoe or processing performance data out of the sensor data, the sensor device 50 comprises a transceiver 54. The transceiver 54 could be a Bluetooth, BTLE, Wi-Fi, NFC, cellular network transceiver or the like. It would also be possible to exchange the transceiver with a transmitter to transmit the data like described above. Also, it is possible to transmit the data via a wired connection in which case the transceiver 54 would be a driver for a USB or serial connection for example.
In a minimal setup, the shoe may include a step counter 55 which is able to count the steps taken by the user while he/she is running or walking. Using data from the step counter 55 it is at least possible to determine whether the user is an intensive runner, e.g., how often he/she runs and how long such a run lasts on average. Furthermore, it is possible to extract the pace, i.e. steps per minute. This information may be used in the context of the present invention to build a digital model of a customized sports shoe and to manufacture such a customized shoe based on the digital model, e.g., by altering a custom computational traction profile. If, for example, the user turns out to be an intensive runner with a high pace, the customized shoe could be provided with more or less cushioning characteristics to avoid injuries. Additionally, more traction elements could be added, moved, re-shaped, resized, etc., in order to provide particular traction patterns for specific movements. The step counter may be based on an accelerometer and/or at least one piezo element.
In a more advanced setup, the shoe is equipped with an acceleration sensor 56 and a gyroscope 57 as indicated by the dashed boxes. Data from these sensors allow a more advanced analysis of the person's gait cycle. Such a setup uses the lowest power for a gait cycle analysis. The power for such a setup could be provided by energy harvesting techniques as described above. In an alternative setup the shoe comprises an acceleration sensor 56 and a magnetometer 58 to allow for a gait cycle analysis. It is also possible to have all three sensors, i.e. acceleration sensor 56, gyroscope 57 and magnetometer 58 integrated into a shoe which would deliver best results for a gait cycle analysis. In general, it is possible to use only one of the sensors shown
Additional sensors such as bending sensor 59 may be included. Such a sensor is able to measure the bending of the shoe, e.g. of its sole. A temperature sensor 510 may measure the outside air temperature and/or the temperature of the person's body or the temperature in the shoe when wearing the shoe.
Pressure sensor 511 is a pressure sensor matrix as described herein. Using such a pressure sensor matrix, it is possible to obtain a series of “pressure maps” (similar to so-called “heat maps”) that encode the dynamics of how the foot behaves while moving, e.g., the distribution of pressure over time. This information may enable real-time interactions with the user like for example advises to correct movement while running to prevent injuries.
Moisture sensor 512 is able to measure the moisture inside the shoe and/or outside. Moisture data from inside the shoe may provide information about the person's perspiration. If perspiration is high, the customized shoe may be provided with moisture wicking materials and/or good air ventilation. Moisture data from outside the shoe may indicate whether the person typically runs in bad weather conditions such as rain. If this is the case, the customized shoe may be provided with water repellent coatings.
Heart rate (HR) sensor 513 is able to measure the person's heart rate which may allow to infer the person's fitness level.
Gas sensor 514 may give an indication about the sweat consistence. This may give an indication whether the person is sick (e.g. having athlete's foot (Fuβpilz in German)). In a shirt, the gas sensor 514 could give an indication about the smell level, which then could an indication for the health status.
The physiological characteristics collected by the system may include, but are not limited to, gait characteristics, such as foot strike type (e.g. heel, midfoot, forefoot, etc.), rate of pronation or supination, and degree of pronation and supination.

Personal information may include information such as their name, prior injury information, height, weight, gender, shoe size, an athletic goal, intended athletic environment or terrain, intended athletic activity duration, intended athletic activity frequency, intended athletic activity distance, quantitative or qualitative preferences about athletic equipment or footwear (such as level of cushion, preference of weight, materials and the like), and current athletic footwear.
In some embodiments, the system may receive biometric data via a local wired or wireless connection. In some embodiments the system may monitor and receive data from an individual in real time during an athletic activity, such as jogging.
Sensor module 102 may include one or more temperature sensors, a heart rate monitoring device, a pedometer, and/or an accelerometer-based monitoring device. Accelerometer, pressure sensor, force sensor, optical stress/strain sensor, temperature sensor, chemical sensor, global positioning system, piezoelectric sensor, rotary position sensor, magnetometer, gyroscopic sensor, heart-rate sensor, goniometer, electrocardiogram (ECG) sensor, electrodermograph (EDG) sensor, electroencephalogram (EEG) sensor, electromyography (EMG) sensor, feedback thermometer sensor, photoplethysmograph sensor, plethysmograph sensor, moisture sensor(s), skin conductance sensor, galvanic skin response (GSR) sensor, electrodermal response (EDR) sensor, psychogalvanic reflex (PGR) sensor, skin conductance response (SCR) sensor, skin conductance level (SCL), sensor or the like.
Sensors of sensor module 102 may be capable of measuring a variety of athletic performance parameters. The term “performance parameters” may include physical parameters and/or physiological parameters associated with the individual's athletic activity. Physical parameters measured may include, but are not limited to, time, distance, speed, pace, pedal count, wheel rotation count, rotation generally, stride count, stride length, airtime, stride rate, altitude, temperature, strain, impact force, jump force, force generally, and jump height. Physiological parameters measured may include, but are not limited to, heart rate, respiration rate, blood oxygen level, blood lactate level, blood flow, hydration level, calories burned, or body temperature.
Data collected by sensor module 102 may classify individuals based on their running style, utilizing data analysis such as an anterior-posterior plot angle vs. time; medial-lateral plot angle vs. time; and the like. Calculations of these characteristic many be used to group individuals into different categories (groups), such as a heel striker, a mid foot striker, a forefoot striker, a pronator, supinator, a neutral individual, or some combination of characteristics. In some embodiments, gait analysis may utilize personal information of individual 102, such a gender, shoe size, height, weight, running habits, and prior injuries.
In some embodiments, a regression analysis can be used to determine gait characteristics such as foot strike type, rate of pronation, degree of pronation, and the like based on acceleration data obtained from sensor module 102. In some embodiments, the regression analysis can be used to determine gait characteristics such as foot strike type, rate of pronation, degree of pronation, and the like based on other data such as magnetometer data, angular momentum sensor data, or multiple types of data. In some embodiments, the analysis can include other user-input information such as prior injury information, an athletic goal, intended athletic environment or terrain, intended athletic duration, and current athletic footwear.
Athletic goals may be, for example, training for a race, to stay healthy, to lose weight, and training for sports. Other examples of athletic goals may include training for a race, or other sporting event, improving individual fitness, simply enjoy running, or the like. Frequency intervals may include for example about 1 to 2 times per week, about 3 to 4 times per week, about 5 to 7 times per week, or the individual doesn't know. Length intervals may include for example about less than about 5 miles per week, about 5 to 10 miles per week, about 10 to 20 miles per week, greater than about 20 miles per week, or the individual doesn't know. Examples of intended athletic terrain environments may include roads, track, treadmill, trail, gym, or particular athletic fields designed for a specific sport. Examples of athletic equipment preferences may include for example more cushioning, less weight, better fit, strength, durability, intended athletic activity range, balance, weight balance, more color choices, and the like.
