The invention relates to a system and method for assisting an operator in creating an embroidered fabric from an embroidery design. In particular, the invention recommends a compatible combination of parameters for implementing the embroidery design as an embroidered fabric.
In order for an operator of an embroidery machine to know how well a design will sew, the operator must select various parameters which need to be compatible with each other and with the design. In order to confirm compatibility, the operator actually sews the design as a test. This process of selecting parameters and making a test design can be extremely time consuming, given that the average machine will sew at a rate of 400 stitches per minute, and designs typically contain 10,000-80,000 stitches. There is a need for a system and method which can assist the operator in selecting parameters and providing the operator guidance on the interrelationship between the selected parameters and other parameters that can affect the quality of the resulting embroidered design and on the effectiveness of producing the embroidered design. There is also a need for a system and method which minimizes or avoids the need for sewing all or part of the design as a test to determine the quality of the resulting embroidered design and the effectiveness of the embroidery process.
In one form, the invention comprises computer-implemented system for assisting an operator in analyzing embroidery design which will be used by an embroidery machine to create an embroidered fabric. A knowledge base contains a plurality of parameters which relate to embroidery designs and the process of making an embroidered fabric from an embroidery design. A rules base of rules interrelates two or more of the parameters. Selection software is responsive to the operator for permitting the operator to select a parameter and for defining an additional parameter from the plurality of parameters. The defined parameter is a function of the operator selected parameter. Analysis software applies the rules to the defined parameter and generates one or more recommended parameters from the plurality of parameters. The recommended parameter is a function of the defined parameter. Display software provides a display corresponding to the selected and defined parameters and corresponding to one or more recommended parameters such that the one or more recommended manufacturing parameters define parameters for the embroidery design using the embroidery machine.
In another form, the invention comprises a method for assisting an operator of an embroidery machine in analyzing an embroidery design using a knowledge base of parameters relating to embroidery designs and a rules base of rules interrelating the parameters. The method comprises the steps of designating selected and defined parameters relating to the embroidery design where the defined parameter is a function of the selected parameter; applying the rules to the defined parameter; generating one or more recommended parameters as a function of the application of the rules to the selected and defined parameters; and displaying the selected and defined parameters and the one or more recommended parameters such that the one or more recommended parameters define parameters for the embroidery design using the embroidery machine.
In another form, the invention includes a system for assisting an operator in analyzing an embroidery design which, will be used by an embroidery machine to create an embroidered fabric. The system comprises a personal computer which includes a memory which contains a knowledge base of parameters relating to embroidery designs and a memory of a rules base of rules which interrelate two or more of the parameters. The system also comprises a processor that executes selection software responsive to the operator for permitting the operator to select a parameter and for defining an additional parameter. The defined parameter is a function of the operator selected parameter. Analysis software applies the rules to the defined parameter and generates one or more recommended parameters as a function of the defined parameter. Display software displays the selected and defined parameters and the one or more recommended parameters such that the one or more recommended parameters define parameters for the embroidery design using the embroidery machine.
This expert system and method of the invention has a number of advantages over the prior art. The expert system and method provide direction and guidance to an operator of an embroidery machine to enable the operator to quickly, efficiently and effectively select parameters relating to an embroidery design to be created as an embroidered fabric so that the operator can effectively produce a quality embroidered fabric from the embroidery design.
Other objects and features will be in part apparent and in part pointed out hereinafter.
Computer Program Listing Appendix is an exemplary listing of one preferred embodiment of a software program according to the invention. As noted above, it is included with this Application on a CD-ROM.
Corresponding reference characters indicate corresponding parts throughout the drawings.
One purpose of the expert system and method of this invention is to allow operators who wish to produce an embroidered fabric from an embroidery design to have access to a knowledge base of parameters relating to the embroidery design and a rules base of rules for interrelating two or more of the parameters. The system and method interact with the operator and help the operator produce a quality embroidered fabric from the embroidery design. Generally, the operator will interact with an expert system and/or method which contains analysis software that allows the system to evaluate various combinations of selected and defined parameters based on the rule base. The invention assists the operator in selecting a compatible combination of parameters from a plurality of parameters including parameters from the categories of: hooping technique, stabilization technique, topping material, backing material, thread weight, thread type, needle type, needle size, embroidery density, project/fabric type, fabric thickness, fabric density, fabric stretch and design size.
The expert system and method of the invention analyzes the selected and defined parameters and recommends to the operator additional parameters for a quality embroidered fabric from an embroidery design. Additionally, the system provides the operator with comments related to the selected, defined and/or recommended parameters to provide the operator with additional information with regard to the application of the various parameters. The system may also provide the operator with photographs or multimedia presentations associated with one or more of the selected, defined and/or recommended parameters.
In a next step 104 the software defines one or more additional parameters referred to as the defined parameters. In this step, the expert system of this invention designates one or more additional defined parameters from a plurality of parameters which are a function of the operator selected parameter of step 102. Preferably, both the selected parameter selected by the operator at step 102 and the defined parameters defined at step 104 are parameters that are contained in a knowledge base which contains a plurality of parameters related to embroidery design. For example, where the selected parameter selected by the operator in step 102 is cotton/polyester woven, the parameters designated as the defined parameters in step 104 could be a medium fabric thickness and no fabric stretch. In an optional step 106, the system provides the operator the ability to modify the defined parameter as designated by the expert system in step 102. For example, where the selected parameter is cotton/polyester woven and the defined parameters are medium fabric thickness and no fabric stretch, the operator has the opportunity to select a modified defined parameter for the fabric thickness and/or the fabric stretch. The operator could select a heavy fabric thickness rather than the system designated defined parameter of medium fabric thickness.
In a next step 108, the rules base of rules is applied to the selected and the defined parameters. The rules base is a collection of rules that interrelate two or more of parameters in the embroidery process. The rules provide the various interrelationships between parameters and are preferably based on the experience of experts in the field of the art. The rules step 108 receives as input the selected parameter and the defined parameters, the latter either being as designated by step 104 or as modified by the operator in step 106. Based on the application of the rules to the selected parameter and the defined parameters, step 110 generates the recommended parameters which are a function of the defined parameter. These one or more recommended parameters are additional parameters that will assist the operator and provide direction for the creation of an embroidered fabric from an embroidery design. Where the selected parameter is cotton/polyester woven and the defined parameters are medium fabric thickness and no fabric stretch, the recommended parameters could include an embroidery needle type, a needle size of 11-12, a thread weight of 40 weight, and a tear-away backing type.
A next optional step 112 generates comments that are a function of the selected parameter, the one or more defined parameters and/or the one or more recommended parameters. The comments provide general embroidery parameter and process application comments intended to assist the operator in applying the parameters during the embroidery process and the creation of a quality embroidered fabric from an embroidery design. A final step 114 displays the one or more defined and one or more recommended parameters. The display step 114 also includes the displaying of any related text comments, photographs, or multimedia presentations if available. The display step 114 could also provide a printout of the parameters and/or the comments, or the storage of the information in a memory file or on a memory media such as a floppy-disk or CD-ROM.
As noted,
Next, as prompted by the expert system as shown on the screen shot at 203, the operator has the ability to modify the defined parameters as designated by the system in pull down menu 206 for fabric thickness and pull down menu 207 for fabric stretch. While not shown in
Referring again to
Finally, the screen shot of
In other embodiments of this invention, other screen shots would show other parameters that would be prompted as the initial selection parameter in prompt 201, as the defined parameters of fabric thickness 204 and fabric stretch 205, as the parameters displayed in the pull down menus of 202, 206 and 207, and as the recommended parameters 208. These parameters could be any parameters from the category of parameters including hooping technique, stabilization technique, topping material, backing material, thread weight, thread type, needle type, needle size, embroidery density, project/fabric type, fabric thickness, fabric density, fabric stretch and design size.
Additionally, in another embodiment of this invention, the operator may be presented with photographs or multimedia presentations in the screen shot that also assist the operator in applying the parameters and in the creation of the embroidered fabric.
Additionally, the processor 302 is connected to selection software 304, analysis software 312 and display software 314. The selection software 312 assists the operator in selecting a selected parameter and designates one or more related defined parameters from the plurality of parameters. Additionally, the selection software 312 enables the operator to modify the defined parameters as designated by the selection software 312. The analysis software 312 applies the rules to the defined parameters and generates one or more recommended parameters as a function of the defined parameter. The display software 314 provides a display 316 corresponding to the selected parameter, the defined parameter and the one or more recommended parameters. The display software may also provide for the display 316 of comments, photographs, or multimedia presentations which are a function of the selected parameter, the defined parameter, and/or the one or more recommended parameters. These comments, photographs or multimedia presentations may be obtained from the knowledge base of parameters memory 308 or from other sources.
Interconnected to the selection software 304 is one or more input devices. In
In other embodiments, processes and function described above may be performed by other software configurations, software modules or on an integrated basis. The identification of the software and memory components provided in
In operation, the operator starts the expert system and method by opening the expert system screen shot as depicted in FIG. 2. The operator is prompted in step 102 by the selection software 304 to select an initial selected parameter such as the project/fabric type 201. The operator selects the initial selected parameter from the pull down menu 202. These parameters are stored on the system in the knowledge base of parameters memory 308. In step 104, the selection software 304 designates the defined parameters which are a function of the operator selected parameter of step 102. In step 106, the selection software 304 enables the operator in pull down menus 206 and 207 to modify the system designated defined parameters. In step 108, once the operator either modifies the defined parameter or chooses to accept the system designated defined parameters, the analysis software 310 applies the rules base of rules from the rules base of rules memory 310 to the selected and defined parameters and generates in step 110 the recommended parameters. The recommended parameters are displayed on the screen as recommendations 208 as enabled by the display software 314 and on the display 316. Additionally, the display software 314 provides on the display 316 associated project notes 220 which may include comments as provided in step 112. Additionally, photographs or multimedia presentations may also be provided by the processor 302 to the display software 314 for display on the display 316.
Annotated Description of the Computer Program Listing Appendix on CD-ROM
The Computer Program Listing Appendix on CD-ROM is an exemplary listing of one preferred embodiment of a software program. The expert system and method of the invention assists an operator in creating an embroidered fabric from an embroidery design.
The expert system includes the knowledge base of parameters (see Computer Program Listing Appendix on CD-ROM, lines 1-130) related to embroidery designs. The expert system also includes a rules base of rules (see Computer Program Listing Appendix on CD-ROM, lines 132-211) that interrelate two or more of the parameters. In addition, the expert system may include selection software (Computer Program Listing Appendix on CD-ROM, lines 212-213) which provides the operator the ability to select the selected parameter and for the expert system to designate the defined parameters based on the operator's selection of the project/fabric type. Additionally, the selection software provides the operator the ability to modify the designated defined parameters.
The expert system includes analysis software (Computer Program Listing Appendix on CD-ROM, lines 214-288 and 290-324) that applies rules to the selected and defined parameters. The rules are based on the experience of experts in the field of the art. The expert system also provides comments, photographs or multimedia presentations which are a function of the selected parameter, the defined parameter and/or one or more recommended parameters. In one embodiment, the comments are contained in the knowledge base or parameters and retrieved by the analysis software to include in the recommendation or for forwarding to the display software. The expert system of this invention also includes display software (Computer Program Listing Appendix on CD-ROM, lines 131, 289, and 325-326) for providing a display corresponding to recommendations resulting from the application of the rules to the designated parameters.
Referring again to Computer Program Listing Appendix on CD-ROM, it can be seen that lines 1-59 specify the text string resources used for the knowledge base of parameters, lines 60-64 specify the general purpose string resources, lines 65-72 specify the hooping resources, lines 73-84 specify the stabilization resources, lines 85-88 specify other string resources, lines 89-102 specify needle and thread string resources, and lines 103-126 specify the project string table indexes. In addition, lines 137-209 specify the sample code function for designating a recommended parameter where there is no operator modification to the defined parameters. Lines 214-278 provide the rules for designating a recommended parameter where an operator modifies the defined parameters.
Referring again to
Once the rule base is applied, the analysis software recommends 208 the type of needle as an embroidery needle 210 and recommends a size of the needle as size 11-12 210 (Computer Program Listing Appendix on CD-ROM, line 93). The operator may modify the defined parameter of fabric thickness 206 and/or fabric stretch 207 by modifying the defined parameters. For example, if the thickness of the cotton/polyester woven project was modified to heavy, based on the rule base of rules, the expert system could recommend the needle type as been a “jean needle” (Computer Program Listing Appendix on CD-ROM, lines 219-220) rather than an embroidery needle. The analysis software also recommends a 40 weight thread weight (Computer Program Listing Appendix on CD-ROM, line 98). Finally, the display software presents comments 220 corresponding to the selected, defined and/or recommended parameters. The comments shown in
The exemplary computer code as provided in Computer Program Listing Appendix on CD-ROM is only one embodiment of the possible forms of this invention as provided by computer code. In other embodiments of this invention, computer program implementations of FIG. 3 and Computer Program Listing Appendix on CD-ROM can be written in different codes, different software code modules or on a fully integrated basis.
In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.
When introducing elements of the present invention or the embodiment(s) thereof, the articles “a,” “an,” “the,” and “said” are intended to mean that there are one or more of the elements.
