Engineering Contradiction Analysis
1Length of moving object
If traditional contact connector structure is used, then reliable electrical connection is achieved, but thickness and mounting space increase
Solution Approach 1:
The contact connector is divided into distinct functional segments: a substrate providing structural support, a metal elastic sheet providing contact pressure, and a connection contact providing electrical connection. This segmentation allows each component to be optimized independently, reducing overall thickness while maintaining connection reliability through the specialized function of each segment.
Solution Approach 2:
The metal elastic sheet acts as a flexible thin film component that provides the necessary contact pressure and electrical conductivity. Its flexibility allows it to deform and maintain reliable electrical connection even in a thinner profile, replacing traditional rigid contact structures that required more space.
2Device complexity
If traditional contact connector structure is used, then electrical connection is ensured, but number of parts and assembly complexity increase
Solution Approach 1:
The substrate and mounting portion are merged into a single integrated component, eliminating the need for separate housing and mounting brackets. The metal elastic sheet is directly fixed to the substrate, combining structural support and electrical connection functions in fewer parts, thereby reducing assembly complexity while maintaining connection reliability.
Solution Approach 2:
The substrate serves multiple functions: providing structural support, facilitating mounting to the electronic device, and serving as a base for fixing the metal elastic sheet. The metal elastic sheet simultaneously provides mechanical contact pressure and electrical conductivity. This multi-functionality reduces the number of separate parts needed while ensuring reliable electrical connection.
