Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sewing machines and data processing devices face challenges in efficiently aligning and sewing patchwork patterns due to difficulties in verifying the position of boundary lines between divided patterns, making the operation complex and inconvenient for users.
Innovation Solution
A processing data generation device that includes a processor and memory, which acquires and divides patterns into pieces, sets offset lines for adjacent pieces, and generates processing data to guide the sewing machine in aligning and sewing the pieces along these lines, eliminating the need for users to manually verify sewing positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If boundary lines are printed between divided patterns to indicate sewing positions, then users can identify where to sew, but it becomes difficult to verify the position of boundary lines and the operation becomes complex
Solution Approach 1:
The patent introduces offset lines as intermediary elements that are offset from the actual boundary lines by a predetermined distance. These offset lines serve as mediators between the printed boundary lines and the sewing position, allowing users to easily identify where to sew without directly verifying boundary line positions. The offset lines are printed on adjacent pattern pieces at positions that correspond to the sewing line when pieces are aligned, thus simplifying the operation.
2Manufacturing precision
If users manually verify boundary line positions to ensure proper alignment, then sewing accuracy can be maintained, but the operation becomes time-consuming and complex
Solution Approach 1:
The patent applies preliminary action by pre-calculating and pre-printing offset lines at positions that are offset from boundary lines by a predetermined distance. This preliminary positioning allows users to directly use the offset lines as sewing guides without needing to manually verify boundary line positions during the sewing process, thus maintaining precision while reducing time consumption.
3Ease of operation
If offset lines are set at positions separated from adjacent portions by a predetermined distance, then users can easily identify sewing positions without verifying boundary lines, but additional processing steps are required
Solution Approach 1:
The patent replaces manual mechanical verification of boundary line positions with an automated computational system. The processor automatically calculates offset line positions by offsetting from boundary lines by a predetermined distance and generates processing line data accordingly. This substitution of mechanical verification with computational processing simplifies the user operation while managing the complexity through automation.
