Abstract

Computer based systems and methods for designing and manufacturing consumer products, including knit footwear uppers, and the like. The system simulates deformations of knit structures and allows the user to control and visualize compensations in the structure(s) of the knitted component to better match between an intended knit design and the actual physical knitted component outcome. The system may modify a knit design of a knitted component to compensate for a predicted/estimated deformation behavior of the knitted component, for example, by duplicating one or more portions of a knit structure associated with the knit design.

First claim

The invention claimed is:

1. A method, comprising:
predicting, by a computing device and based on a simulation model for a plurality of knit structures of a knit design, a deformation of a knit structure of the plurality of knit structures;
modifying, by the computing device, the knit design to compensate for the deformation associated with the knit design, wherein the modifying comprises duplicating one or more portions of the knit structure; and
sending, to a knitting machine, knitting instructions associated with the modified knit design.

2. The method of claim 1 , further comprising:
generating, by the computing device and prior to fabricating a knitted component associated with the knit design, a visual representation of the deformation associated with the knit design.

3. The method of claim 1 , wherein the deformation comprises a deformation of a knitted component, associated with the knit design, under a resting condition-.

4. The method of claim 1 , further comprising:
determining, by the computing device, an allocation of the plurality of knit structures of the knit design.

5. The method of claim 4 , wherein the determining of the allocation of the plurality of knit structures further comprises:
generating, by the computing device, a data structure indicating the knitting instructions for the knitting machine; and
distributing, to the data structure, a plurality of rubrics associated with the plurality of knit structures.

6. The method of claim 1 , wherein the modifying of the knit design further comprises:
determining, based on one or more compensation routines, a plurality of predicted compensation results corresponding to the knit design; and
determining, based on scores associated with the plurality of predicted compensation results, a compensation routine, of the one or more compensation routines, to compensate for the deformation.

7. The method of claim 1 , further comprising:
determining first aspect ratios associated with the knit structures;
determining, via one or more compensation routines, one or more other knit structures, of the plurality of knit structures, of the knit design; and
determining scores for the knit structures, based on a comparison of the first aspect ratios and second aspect ratios, wherein the second aspect ratios are associated with the one or more other knit structures.

8. The method of claim 1 , wherein the modifying of the knit design further comprises adjusting a stitch density associated with one or more knit structures, of the plurality of knit structures, of the knit design.

9. An apparatus comprising:
one or more processors; and
memory storing instructions that, when executed, cause the apparatus to:
predict, based on a simulation model for a plurality of knit structures of a knit design, a deformation of a knit structure of the plurality of knit structures;
modify the knit design to compensate for the deformation associated with the knit design, wherein the modifying comprises duplicating one or more portions of the knit structure; and
send, to a knitting machine, knitting instructions associated with the modified knit design.

10. The apparatus of claim 9 , wherein the instructions, when executed, further cause the apparatus to:
generate, prior to fabricating a knitted component associated with the knit design, a visual representation of the deformation associated with the knit design.

11. The apparatus of claim 9 , wherein the instructions, when executed, further cause the apparatus to determine an allocation of the plurality of knit structures of the knit design by:
generating a data structure indicating the knitting instructions for the knitting machine; and
distributing, to the data structure, a plurality of rubrics associated with the plurality of knit structures.

12. The apparatus of claim 9 , wherein the instructions, when executed, further cause the apparatus to:
receive design input data indicating at least one of a set of visual attributes and a set of physical attributes associated with the knit design.

13. The apparatus of claim 9 , wherein the instructions, when executed, further cause the apparatus to modify the knit design by:
adjusting a stitch density associated with one or more knit structures, of the plurality of knit structures, of the knit design.

14. A non-transitory machine readable medium storing instructions that, when executed, cause a computing device to:
predict, based on a simulation model for a plurality of knit structures of a knit design, a deformation of a knit structure of the plurality of knit structures;
modify the knit design to compensate for the deformation associated with the knit design, wherein the modifying comprises duplicating one or more portions of the knit structure; and
send, to a knitting machine, knitting instructions associated with the modified knit design.

15. The non-transitory machine readable medium of claim 14 , wherein the instructions, when executed, further cause the computing device to:
generate, prior to fabricating a knitted component associated with the knit design, a visual representation of the deformation associated with the knit design.
