Sewing Machine Coordinate Data Creating Device for Hand-Drawn Aesthetic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sewing technologies struggle to create a hand-drawn taste in sewing patterns without significantly altering the original style, especially when the distance between needle location points is long, leading to a mechanical impression.
Innovation Solution
A coordinate data creating device and program that adds independent fluctuations to the X-coordinate and Y-coordinate values of needle locations, generating new coordinate data when the distance between sequential needle locations exceeds a predetermined value, allowing for the creation of a hand-drawn taste while maintaining the original pattern's style.
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 imparted to the sewing pattern, but the original style of the pattern is remarkably lost when distance between needle location points is long
Solution Approach 1:
The patent applies local quality by differentiating the processing of needle location points based on their spatial relationships. Intermediate points between sequential needle locations receive fluctuation additions to create hand-drawn taste, while endpoint points maintain stricter adherence to the original pattern coordinates. This localized differentiation allows hand-drawn aesthetic to be applied where appropriate without compromising the overall pattern fidelity.
Solution Approach 2:
The patent segments the needle location points into three categories: intermediate points (which receive fluctuation additions in both X and Y coordinates), endpoint points (which receive fluctuation only in one coordinate), and original pattern points (which maintain original coordinates). This segmentation allows selective application of fluctuation to achieve hand-drawn taste while preserving critical pattern structure.
2Ease of manufacture
If fluctuation is added to coordinate data to create hand-drawn taste, then comfort and warmth are imparted to the seam, but linear expression becomes remarkable when distance between needle location points is long
Solution Approach 1:
The patent applies dynamics by introducing random fluctuation values that vary for each needle location point. Instead of applying a fixed fluctuation amount, the system dynamically generates different fluctuation values (within a predetermined range) for each point, creating natural variations that mimic hand-sewing characteristics and prevent mechanical linear patterns.
Solution Approach 2:
The patent applies local quality by selectively adding fluctuation to intermediate needle location points while maintaining original coordinates for endpoint points. This localized approach ensures that hand-drawn taste is created in the middle sections of the pattern where natural variation is most desirable, while endpoints maintain the structural integrity and overall shape accuracy of the original pattern.
Data Source
AI summary
A data storage unit configured to store a coordinate data of a needle location and an added coordinate data creating unit configured to create a new coordinate data by adding independent original values respectively to an X-coordinate value or a Y-coordinate value for each of the coordinate data stored in the data storage unit are provided. The added coordinate data creating unit makes the independent original values added respectively to the X-coordinate value or the Y-coordinate value of the coordinate data in one needle location same as the independent original values added respectively to the X-coordinate value or the Y-coordinate value of the coordinate data in the other needle location when a distance between the coordinate data of the one needle location and the coordinate data of the other needle location stored in the data storage unit is within a predetermined distance.
