Sewing Machine Coordinate Data Adding Unit for Natural Seam Fluctuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sewing technologies struggle to create a hand-drawn aesthetic in sewing patterns, particularly for simple shapes, as fluctuations in needle location points can result in linear expressions that lack naturalness, especially when the distance between points is large, leading to a mechanical appearance rather than a warm and comfortable one.
Innovation Solution
A coordinate data creating device and program for sewing machines that generate new needle location points on a line connecting continuous points, adjusting X and Y coordinates with independent values to create a natural fluctuation, ensuring the original pattern style is maintained while adding comfort and warmth to the seam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fluctuation is added to needle location points to create hand-drawn taste, then comfort and warmth are improved, but linear expression becomes remarkable when distance between points is long
Solution Approach 1:
The patent divides the line segment between two needle location points into multiple smaller segments by inserting intermediate points. This segmentation allows fluctuation to be applied locally at each segment rather than across the entire long distance, preventing excessive linear expression while maintaining the overall hand-drawn aesthetic.
Solution Approach 2:
The patent applies different fluctuation characteristics to different segments of the line. By calculating intermediate points based on the distance from endpoints and applying fluctuation locally at each segment, the system creates natural-looking variations without imposing uniform linear expression across the entire path.
2Ease of manufacture
If fluctuation is added to create natural taste, then comfort and warmth are improved, but mechanical impression is enhanced when distance between points is large
Solution Approach 1:
By segmenting the long distance into multiple smaller intervals through intermediate points, the patent reduces the visual impact of mechanical straight-line connections. Each short segment can exhibit natural fluctuation, while the cumulative effect maintains the overall pattern shape without creating a mechanical appearance.
Solution Approach 2:
The patent introduces intermediate dimensionality by adding intermediate points that are not just on the straight line but positioned to create natural fluctuation patterns. This adds a dimensional aspect to the path that breaks the mechanical straight-line perception while maintaining the original pattern's overall shape.
3Shape
If intermediate points are added to reduce linear expression, then natural fluctuation is improved, but sewing time increases
Solution Approach 1:
The patent applies fluctuation and intermediate points selectively rather than uniformly across all segments. By calculating intermediate points only where necessary based on the distance between original points, the system achieves natural fluctuation in key areas without excessively increasing the number of sewing operations throughout the entire pattern.
