Conductive Thread Sheet Connector Layout for Stable Garment Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reliability of electrical connections between conductive threads forming flexible conductors and contacts or wiring portions in smart garments is compromised due to small contact areas, affecting the stability of data transmission.
Innovation Solution
A sheet type conductive member with flexible conductors formed of conductive threads is designed to have larger exposure areas at the first and second end portions, ensuring reliable electrical connections by increasing the contact area with contacts and wiring portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible conductors are formed of conductive threads embroidered on or woven into a sheet body, then the garment maintains flexibility and comfort, but the contact area between the conductive threads and contacts/wiring portions becomes small, impairing electrical connection reliability
Solution Approach 1:
The conductive thread density is varied locally within the flexible conductor structure. The first and second end portions have higher conductive thread density (larger exposure area per unit area) to ensure reliable electrical connections, while the joint portion has lower density to maintain flexibility. This local differentiation allows the same conductor to simultaneously achieve good electrical contact at connection points and mechanical flexibility in the middle section.
2Reliability
If the exposure area of conductive thread per unit area is increased at end portions, then electrical connection reliability is improved, but the manufacturing complexity of the sheet type conductive member increases
Solution Approach 1:
The conductive thread density is varied locally within the flexible conductor structure. The first and second end portions have higher conductive thread density (larger exposure area per unit area) to ensure reliable electrical connections, while the joint portion has lower density to maintain flexibility. This local differentiation allows the same conductor to simultaneously achieve good electrical contact at connection points and mechanical flexibility in the middle section.

AI summary
A sheet type conductive member includes a flexible conductor formed of a conductive thread embroidered on or woven into a sheet body, the flexible conductor including a first end portion electrically connected to a wiring portion of a garment, a second end portion electrically connected to a contact, and a joint portion joining the first end portion and the second end portion together, an exposure area of the conductive thread per unit area in the first end portion and the second end portion being larger than an exposure area of the conductive thread per unit area in the joint portion.
