Knit Design Apparatus Pattern Distortion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing knit design methods for flatbed knitting machines face distortion issues when there are differences in knitting stitch structure or length between specified and base areas, leading to pattern collapse when extra knitting is added to compensate for these differences.
Innovation Solution
A method and apparatus that allow for the specification of a target area with a constant knitting width, partitioning it from a base area, sliding it to form a rectangular shape, appending extra knitting to address structural differences, and reconnecting it to the base area to minimize distortion and maintain pattern integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If extra knitting is added to compensate for length difference between specified area and base area, then distortion is decreased, but pattern regularity is damaged and pattern design collapses
Solution Approach 1:
The knitting design is divided into a specified area and a base area that can be independently processed. The specified area is separated, deformed into a rectangular target area, and processed independently before being reconnected to the base area, allowing extra knitting to be added without affecting the overall pattern regularity.
Solution Approach 2:
Extra knitting is added to the specified area before pattern design is finalized. By performing the extra knitting operation in advance on the separated specified area, the system compensates for length differences and distortion before the pattern is fully established, preventing pattern collapse.
2Ease of operation
If specified area is deformed to simple rectangular shape for easy design, then design ease is improved, but distortion increases due to difference in knitting stitch structure
Solution Approach 1:
The knitting design is segmented into a specified area and a base area. The specified area can be independently deformed into a simple rectangular target area for easy pattern design, while the base area maintains its original structure. This segmentation allows local deformation without affecting the overall fabric integrity.
Solution Approach 2:
Different areas of the knitting design have different properties: the specified area is transformed into a rectangular shape with modified knitting stitches to facilitate easy design, while the base area retains its original knitting structure. This local differentiation allows each area to have optimal characteristics for its specific function.
3Adaptability or versatility
If knitting stitches are made different between specified area and base area to accommodate structural differences, then adaptability is improved, but device complexity increases
Solution Approach 1:
The knitting design is divided into a specified area and a base area that can have different knitting stitch structures. The specified area uses knitting stitches adapted to its specific requirements (e.g., different loop lengths or stitch types), while the base area uses standard stitches. This segmentation allows structural adaptability without requiring the entire knitting system to become complex.

AI summary
[Problem to be solved] There is provided a knit design method and a knit design apparatus which make it possible to easily append extra knitting and prevent a pattern from collapsing in a state where the extra knitting is appended. [Solution] In Fig. 1(a), a specified area 2 to which a purl knitting is applied is set to have a constant knitting width of ten stitches from an end, for example, on a knitting stitch image 1. In Fig. 1(b), a start position 4f is set and the specified area 2 is slid in a course direction so as to be deformed to a target area 2a having a simple shape. In Fig. 1(c), a pattern 4 is developed from the start position 4f on the target area 2b to which extra knitting 5 have been appended based on the difference between the length 1c of the outer edge 1a and the length ld in the wale direction such that distortion generated due to the difference is decreased. The target area 2b on which the pattern 4 has been developed is returned so as to be connected to the base area 3, so that the pattern 4 such as a purl pattern can be prevented from collapsing.
