Solution Overview
Problem
The increased resistance of conductive subsidiary members in electronic devices can lead to malfunctions of integrated circuit chips and electrical components, affecting the performance of multimedia devices with complex functions.
Innovation Solution
A conductive member is designed with an elastic member and a conductive plate, where the elastic member is partially accommodated in a mechanical support part, and the conductive plate is electrically connected to a panel conductive layer, featuring a base region surrounding the elastic member and wing regions to maintain electrical connectivity while absorbing shocks and maintaining rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conductive subsidiary member is used to connect the display and mechanical support part, then electrical connectivity is achieved, but resistance increases causing malfunctions and performance degradation
Solution Approach 1:
The conductive member is constructed as a composite structure combining an elastic member (first material) and a conductive plate (second material different from the first). This composite design allows the elastic member to provide mechanical compliance and shock absorption while the conductive plate ensures low-resistance electrical connectivity, thereby reducing vertical resistance and preventing signal degradation without compromising connection reliability
Solution Approach 2:
The elastic member is at least partially accommodated within the mechanical support part, creating a nested configuration. This nesting allows the conductive plate to extend from the elastic member and establish direct electrical contact with both the display and mechanical support part, providing multiple parallel conduction paths that reduce overall resistance and prevent desense while maintaining structural compactness
2Ease of manufacture
If the conductive member structure is simplified, then manufacturing is easier, but electrical connectivity and shock absorption performance deteriorate
Solution Approach 1:
The conductive member is segmented into two functional parts: an elastic member for mechanical support and shock absorption, and a conductive plate for electrical connectivity. This segmentation allows each component to be optimized independently for its specific function while maintaining ease of manufacture through modular assembly, preventing the need for complex monolithic structures that would compromise reliability
