Sewing Data Generation Using Reference Line Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quilting data generation devices require significant time and effort to generate sewing data for echo quilting designs, which involves forming stitches along multiple wave-like lines surrounding a motif, making it inconvenient for users.
Innovation Solution
A non-transitory computer-readable medium and sewing machine that include a processor to generate sewing data by acquiring a reference line and arrangement conditions, allowing for the precise placement of multiple lines with different spacings, such as a first line, second line, third line, and fourth line, within a sewing region, using the reference line as a reference, thereby simplifying the process of creating echo quilting patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual method is used to generate sewing data for echo quilting, then flexibility in design is maintained, but time consumption and operational complexity increase significantly
Solution Approach 1:
The patent segments the echo quilting line arrangement into multiple independent components: a reference line, multiple target lines with different spacings, and automated positioning mechanisms. This segmentation allows the system to handle complex multi-line arrangements by processing each line independently according to its specific spacing requirements, thereby generating sewing data efficiently without overwhelming complexity.
Solution Approach 2:
The patent implements preliminary action by pre-establishing the reference line and pre-calculating the positions of multiple lines based on predetermined spacings before actual sewing operations. The system prepares the complete line arrangement configuration in advance, allowing the sewing machine to execute the echo quilting pattern without real-time complex calculations, thus significantly improving data generation speed.
2Loss of time
If automated line arrangement is implemented, then time consumption is reduced, but measurement precision requirements increase
Solution Approach 1:
The patent introduces the reference line as an intermediary element that mediates between the user's design intentions and the automated line positioning system. The reference line serves as a stable baseline from which all other lines are positioned using predetermined spacings. This intermediary approach simplifies the measurement requirements by transforming complex relative positioning problems into simpler distance measurements from the reference, thereby reducing the stringency of precision requirements while maintaining accurate line arrangement.
3Ease of operation
If multiple lines with different spacings are arranged automatically, then operational convenience is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by assigning different spacing characteristics to different lines in the echo quilting pattern. Each line is configured with its specific local spacing requirement (first spacing between first and second lines, second spacing between third and fourth lines) rather than using a uniform spacing throughout. This localized approach allows the system to handle varied line arrangements automatically while keeping the processing logic manageable through systematic handling of individual spacing parameters.

AI summary
A non-transitory computer-readable medium stores computer-readable instructions that are executed by a processor of a sewing data generation device. The computer-readable instructions causing the processor to perform processes. The processes include data generating of generating sewing data for forming stitches along a plurality of lines arranged inside a sewing region in accordance with an arrangement condition, using a reference line as a reference. The plurality of lines include first to fourth lines. The first line is arranged at a position spaced from the reference line in a predetermined direction by a first distance. The second line and the third line are arranged adjacent to each other further in the predetermined direction than the first line, and are spaced from each other by a second distance. The fourth line are arranged at a position spaced from the third line in the predetermined direction by a third distance.
