Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signal paths in electronic devices often lack sufficient elasticity, leading to damage from repetitive use and restricted movement when components are interconnected.
Innovation Solution
The implementation of stretchable fabric signal paths with conductive strands interposed between outer elastic and inner non-elastic fabric layers, allowing for expansion and contraction while maintaining the shape of the conductive strand through anchor points, enabling the path to accommodate stretching and bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rigid signal lines or cables are used to interconnect components, then signal transmission is stable, but the signal path lacks elasticity and becomes damaged after repetitive use
Solution Approach 1:
The signal path is divided into multiple conductive strands embedded within separate fabric layers. Each strand acts as an independent segment that can flex and stretch individually, allowing the overall signal path to accommodate repetitive movement without damage while maintaining electrical connectivity.
Solution Approach 2:
The signal path combines conductive materials (for electrical signal transmission) with elastic fabric materials (for stretchability and flexibility). This composite structure integrates the electrical functionality with the mechanical flexibility needed to prevent damage from repetitive use while maintaining reliable signal transmission.
2Adaptability or versatility
If stretchable fabric signal paths are used to provide elasticity, then movement is accommodated, but the conductive strand may lose its shape and functionality
Solution Approach 1:
The conductive strand is nested within fabric layers that provide structural support. The fabric layers act as protective sleeves that maintain the strand's shape and position during stretching and contracting, preventing the conductive material from deforming or becoming damaged while allowing the necessary elasticity.
Solution Approach 2:
The fabric layers surrounding the conductive strand act as flexible protective shells. These thin fabric structures conform to the strand's shape during movement while providing external support that helps maintain the conductive strand's integrity and functional geometry throughout repeated stretching cycles.

AI summary
A stretchable fabric signal path may include a conductive strand located between first and second outer fabric layers. The outer fabric layers may be formed from intertwined strands of elastic material. The conductive strand may have a wavy shape to accommodate stretching of the stretchable fabric signal path. First and second inner fabric layers may be located between the outer stretchable fabric layers. The inner fabric layers may be formed from intertwined strands of non-elastic material. The inner fabric layers may have strands that are intertwined with the outer fabric layers to serve as anchor points for maintaining the shape of the conductive strand as the stretchable fabric signal path expands and contracts. The outer fabric layers and inner fabric layers may be woven. The conductive strand may convey electrical signals such as audio signals, power signals, data signals, or other suitable signals.
