Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-temperature processes and chemical reduction are used to form flexible electrodes, then electrical conductivity is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent changes the temperature parameter from high-temperature synthesis to room-temperature electroplating, and changes the chemical process from complex chemical reduction to simple electrochemical deposition. This resolves the contradiction by achieving good electrical conductivity through parameter optimization without requiring complex high-temperature equipment or multi-step chemical processes
Solution Approach 2:
The patent replaces the chemical reduction mechanism with an electrochemical plating mechanism. Instead of using chemical reducing agents and complex chemical reactions, the invention uses electroplating to deposit metal particles onto the fabric substrate, simplifying the manufacturing process while maintaining electrical conductivity
2Reliability
If high-temperature synthesis and chemical reduction are used, then electrical conductivity is improved, but manufacturing time increases
Solution Approach 1:
The patent changes the temperature parameter from high-temperature synthesis to room-temperature electroplating, and changes the chemical process from complex chemical reduction to simple electrochemical deposition. This resolves the contradiction by achieving good electrical conductivity through parameter optimization without requiring complex high-temperature equipment or multi-step chemical processes
Solution Approach 2:
The patent skips the time-consuming high-temperature synthesis and complex chemical reduction steps by directly applying electroplating at room temperature. This allows the manufacturing process to rush through to completion in a single deposition step, significantly reducing manufacturing time while maintaining electrical conductivity
3Reliability
If metal particles are coated on fabric substrate, then electrical conductivity is improved, but mechanical stability deteriorates due to poor bonding
Solution Approach 1:
The patent introduces an intermediary treatment of the fabric substrate surface before electroplating, which enhances the bonding between the metal particles and the substrate. This intermediary step ensures strong mechanical adhesion while maintaining the electrical conductivity provided by the metal coating, resolving the contradiction between electrical performance and mechanical stability
