Sewing Machine Partial Pattern Segmentation and Outline Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current overedging sewing machines can only perform either cutting or overedging based on edge data, limiting the ability to process specific parts of an embroidery pattern independently.
Innovation Solution
A non-transitory computer readable storage medium and sewing machine system that acquires and processes embroidery data to generate processing data for selected partial patterns, allowing for the generation of data to perform processing following the shape of specific parts of an embroidery pattern, enabling the sewing machine to cut or sew only part of the pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sewing machine processes the entire embroidery pattern based on edge data, then the completeness of the embroidery is ensured, but the ability to process only specific parts of the pattern is lost
Solution Approach 1:
The embroidery pattern is divided into multiple partial patterns, each with its own identification information. The system can selectively process individual partial patterns by identifying them through their embedded identification data, allowing partial processing without requiring complex manual positioning or pattern reconstruction
Solution Approach 2:
Identification information (such as markers or data tags) is embedded within the embroidery pattern data structure. This copied identification data allows the system to recognize and selectively process specific partial patterns without physically modifying the original pattern design, enabling flexible partial processing through data-based selection
2Manufacturing precision
If edge cutting is enabled with a knife needle, then the outline of the embroidering is cut precisely, but the ability to perform overedging is lost
Solution Approach 1:
The sewing machine system dynamically adjusts its operation mode based on the processed data. By generating separate processing data for different partial patterns, the system can switch between cutting mode (with knife needle) and overedging mode (with sewing needle) for different regions of the embroidery, allowing both operations to be performed on the same pattern without physical reconfiguration
3Adaptability or versatility
If the sewing machine uses a sewing needle for overedging, then the embroidering is completed with decorative stitching, but the ability to cut the outline is lost
Solution Approach 1:
The embroidery pattern is segmented into multiple partial patterns with identification information. This segmentation allows the system to generate distinct processing data for cutting operations versus overedging operations on different partial patterns, enabling both functions to be performed selectively without requiring a single needle type to perform both tasks
Data Source
AI summary
A sewing machine acquires embroidery data of the embroidery pattern formed from a plurality of partial patterns. The sewing machine selects, as a selected partial pattern, at least one partial pattern from among the plurality of partial patterns forming the embroidery pattern, on the basis of the acquired embroidery data. The sewing machine identifies, on the basis of the embroidery data, an outline of the selected partial pattern that was selected. The sewing machine generates processing data for performing processing following the shape of the selected partial pattern, on the basis of the identified outline.
