Dual Contact Member Vertical Gap Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna contact structures in electronic devices fail to ensure a vertical gap between components due to the height of single contact terminals and the thickness of the metal housing, leading to inadequate isolation between antennas and neighboring conductors, such as display panels.
Innovation Solution
A dual contact structure is implemented, comprising a flexible conductive member with a base and two flexible portions of different heights protruding towards the first and second plates, respectively, to establish an electrical path between conductive structures while maintaining a vertical gap, ensuring effective isolation.

Engineering Contradiction Analysis
1Reliability
If single contact terminals are used to connect antennas and printed circuit board, then electrical connection is established, but vertical gap between components cannot be ensured leading to inadequate isolation
Solution Approach 1:
The contact structure is divided into multiple independent contact members (first contact member and second contact member) instead of using a single contact terminal. Each contact member has a specific height and is positioned at a specific location, allowing them to independently establish electrical connections while maintaining vertical gaps between components. This segmentation enables better isolation between the antenna and display panel while still providing reliable electrical connections.
2Reliability
If contact terminal height is increased to ensure vertical gap, then isolation is improved, but device thickness increases
Solution Approach 1:
Different contact members have different heights tailored to their specific positioning requirements and isolation needs. The first contact member has a first height and the second contact member has a second height, allowing each to optimally maintain vertical gaps at their respective locations without uniformly increasing the overall device thickness. This local differentiation of contact member properties enables effective isolation while controlling overall device dimensions.
3Reliability
If multiple single contact terminals are used, then electrical connection reliability is improved, but vertical gap maintenance becomes difficult
Solution Approach 1:
Multiple contact members are integrated into a unified contact structure assembly that is mounted together on the printed circuit board. The first contact member and second contact member are positioned at specific locations and heights within this integrated structure, allowing them to simultaneously maintain vertical gaps while providing reliable electrical connections. This merging approach simplifies the overall implementation compared to separately managing multiple independent contact terminals.
