Electrode-Wiring Cloth via Single Conductive Linear Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrode-wiring-equipped cloth materials for wearable devices suffer from defective connections between the electrode section and the wiring section due to repeated deformation, such as distortion, bending, and elongation, which leads to cracking of connecting materials or members.
Innovation Solution
The solution involves integrating the same single conductive linear body into both the electrode section and the wiring section, eliminating the need for connecting materials or members. This is achieved by weaving, knitting, or embroidering the conductive linear body into the cloth material, ensuring that the electrode and wiring sections are connected seamlessly without external connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrode section and wiring section are connected via a connecting material (e.g., solder or conductive paste) or connecting member (e.g., caulking or connector), then the connection between electrode and wiring sections is achieved, but the connecting part deteriorates due to repeated deformation causing cracking and defective connection
Solution Approach 1:
The patent merges the electrode section and wiring section into a single integrated conductive linear body that extends continuously through the cloth material. This eliminates the separate connecting parts (solder, connectors, etc.) that were previously vulnerable to cracking during repeated deformation. The conductive linear body is formed as one continuous element that is woven, knitted, or embroidered into the fabric, ensuring that no discrete connection points exist to fail under mechanical stress.
2Strength
If a connecting member is used to connect conductive linear bodies, then durability against repeated deformation is improved, but the flexibility of the cloth material is deteriorated due to reduced flexibility at the connecting part
Solution Approach 1:
The patent combines the entire conductive path from electrode to wiring section into a single flexible conductive linear body that moves and deforms uniformly with the cloth material. This eliminates rigid connecting members that would restrict the fabric's natural movement. The continuous conductive element maintains electrical connectivity while allowing the cloth to flex, stretch, and conform to body movements without creating stress concentration points.
