Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conductive fibers used in smart textiles lack elasticity and stretchability, and existing conductive materials face challenges with phase separation and reduced strength due to high carbon black content or poor processability, limiting their application in wearable devices.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If carbon black is mixed with resin to impart conductivity, then conductivity is improved, but strength is reduced due to high carbon black content (higher than 50%)
Solution Approach 1:
The patent changes the type of conductive agent from carbon black to one-dimensional metal materials (such as metal nanowires), which have different physical and chemical properties. This parameter change allows achieving high conductivity with lower filler content, thereby maintaining the strength of the resin matrix.
Solution Approach 2:
The patent creates a composite material system consisting of one-dimensional metal materials dispersed in a resin matrix. This composite structure combines the high conductivity of metal nanowires with the mechanical strength of the resin, resolving the contradiction between conductivity and strength.
2Reliability
If carbon black is mixed with resin to impart conductivity, then conductivity is improved, but phase separation occurs due to poor compatibility between carbon black and resin
Solution Approach 1:
The patent changes the chemical and physical parameters of the conductive agent from carbon black to one-dimensional metal materials. These metal materials have better compatibility with the resin matrix, preventing phase separation and ensuring uniform distribution, thus maintaining compositional stability while achieving conductivity.
3Reliability
If conventional conductive agents are used to improve conductivity, then conductivity is improved, but processability is poor
Solution Approach 1:
The patent changes the form factor of the conductive agent to one-dimensional metal materials (nanowires), which have unique properties such as high aspect ratio and flexibility. These parameters improve processability by allowing better dispersion and integration into the resin matrix during manufacturing, while maintaining high conductivity.
4Reliability
If conventional conductive materials are used, then conductivity is provided, but stretchability is poor and electrical properties change greatly when stretched
Solution Approach 1:
The patent changes the morphology of the conductive agent to one-dimensional metal nanowires, which have high aspect ratios and can deform elastically. This parameter change allows the conductive network to maintain connectivity during stretching, improving both stretchability and the stability of electrical properties under deformation.
Solution Approach 2:
The patent creates a dynamic conductive network using one-dimensional metal materials that can adapt their configuration during stretching. The nanowires can reorient and deform dynamically to maintain conductive pathways, allowing the material to maintain conductivity while being stretched, thus improving adaptability.
5Adaptability or versatility
If conductive material with specific conductive circuit structure design is provided to improve stretchability, then stretchability in one direction is improved, but the process becomes complicated and restricts stretching to only one direction
Solution Approach 1:
The patent changes the approach from designing specific circuit structures to using one-dimensional metal nanowires with inherent high aspect ratio and flexibility. This parameter change eliminates the need for complex circuit designs while achieving multi-directional stretchability, thereby reducing process complexity and increasing versatility.
