Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If too many particles and less glue are arranged in the conductive adhesive to ensure electrical connection, then the electrical conductivity is improved, but the adhesion performance deteriorates and the conductive adhesive is easy to fall off
Solution Approach 1:
The patent changes the physical state of the conductive adhesive from a traditional paste with particles and glue to a gel状 conductive adhesive with specific viscosity (100-10000 cP) and gel content (20-80%). This parameter change allows the adhesive to maintain both good electrical conductivity and strong adhesion performance simultaneously, resolving the contradiction between conductivity and adhesion.
2Strength
If few particles and more glue are arranged in the conductive adhesive to ensure the adhesion performance, then the adhesion performance is improved, but the resistance is relatively large and the electrical connection performance is poor
Solution Approach 1:
The patent modifies the conductive adhesive to have specific gel content (20-80%) and viscosity (100-10000 cP), transforming it from a particle-glue mixture to a gel-based material. This parameter change enables the adhesive to achieve both strong adhesion and low resistance, simultaneously improving both adhesion performance and electrical connection performance.
3Adaptability or versatility
If the volume or shape of the conductive adhesive matrix changes under stress and climate conditions, then the stacking state of conductive particles changes, but the electrical connection performance becomes unstable
Solution Approach 1:
The patent uses a gel-based conductive adhesive that combines the properties of gel materials with conductive fillers. The gel matrix provides structural stability and resistance to volume/shape changes under stress and climate conditions, while maintaining stable electrical connection performance. This composite material approach resolves the contradiction between adaptability to environmental conditions and stability of electrical performance.
