Conductive Line Stitching in Smart Clothing Hem
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductive lines in smart clothing are uncomfortable due to being visible on the surface or embedded through adhesive films or hemming, which complicates integration with sewing processes and requires additional processing steps, making it difficult to achieve a one-time sewing operation.
Innovation Solution
A method where a metal line is arranged in a protection layer to form a conductive line, positioned on the edging parts of stacked cloth sheets, stitched inside the sewing line, and connected with a device for data transmission, allowing for one-time sewing and concealment of the conductive line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conductive lines are attached to the surface layer by adhesive plastic films, then the conductive line can be mounted, but it forms a projection that impresses the skin and causes discomfort
Solution Approach 1:
The conductive line is nested within the hemmed edge structure of the clothing, specifically positioned inside the folded edge and secured through stitching. This nesting approach eliminates the projection effect that causes skin discomfort while maintaining the conductive line's functionality for signal and power transmission.
Solution Approach 2:
The conductive line is transitioned from a surface-level attachment (2D plane) to a three-dimensional integration within the hemmed edge structure. By embedding the conductive line within the folded edge and securing it through stitching, the solution moves the conductive line into a different spatial dimension that eliminates skin contact while maintaining functionality.
2Object-affected harmful factors
If conductive lines are coupled inside the clothing through hemming, then the conductive line is concealed, but additional processing steps are required and one-time sewing operation cannot be achieved
Solution Approach 1:
The conductive line attachment process is merged with the existing hemming and stitching operations. The conductive line is positioned within the folded edge and secured using the same stitching mechanism that attaches the hem to the main fabric, eliminating the need for separate attachment steps and enabling one-time sewing operation.
Solution Approach 2:
The stitching operation is given multiple functions: it simultaneously attaches the hem to the main fabric and secures the conductive line within the hemmed edge. This multi-functional approach eliminates the need for separate processing steps while achieving both concealment and functional integration of the conductive line.
3Object-affected harmful factors
If conductive lines are stitched inside the stitching line, then the conductive line is concealed and comfortable, but the integration process becomes more complex
Solution Approach 1:
The conductive line is pre-positioned within the folded edge of the hem before the stitching operation begins. This preliminary positioning ensures that the conductive line is correctly placed and concealed within the hemmed edge, while the subsequent stitching operation simply secures it in place without requiring complex integration procedures.

AI summary
A conductive line stitching method is disclosed, in which a metal line (11) is arranged in a protection layer (12) to form a conductive line (10), which is subjected to the steps of forming conductive line, disposing cloth (20), conducting stitching (30), combining device (40), and connecting conductive line (10) to have the conductive line located in edging parts (21) to facilitate a subsequent operation for connection with a device (40), thereby achieving effect of being processed with a one-time process and concealing the conductive line.
