Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signal contactors that connect flat cables and printed circuit boards face a trade-off between mechanical and electrical performance, where improving mechanical performance often compromises electrical performance due to their single-member design.
Innovation Solution
A contact terminal design featuring independent pressing and electrical connection members, allowing for improved mechanical design without compromising electrical performance. The pressing member is designed with elastic deformation parts, and the electrical connection member includes a flexible printed circuit board with insulating layers to maintain constant electrical length during deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the signal contactor is designed as a single member performing both electrical and mechanical functions, then the structure is simplified, but improving mechanical performance results in decreased electrical performance
Solution Approach 1:
The contact terminal is divided into three independent members: a pressing member for mechanical pressing, a contact part for electrical contact, and an electrical connection member for signal transmission. This segmentation allows each component to be optimized for its specific function without compromising other performance aspects.
Solution Approach 2:
The electrical connection member is extracted as a separate component from the pressing member. The electrical connection member includes a flexible printed circuit board with conductive paths that are electrically connected to the contact part, allowing electrical functions to be independent of mechanical pressing functions.
2Length of moving object
If the pressing member is designed with increased spring stroke for better mechanical performance, then the electrical length of conductive paths may vary, degrading electrical performance
Solution Approach 1:
The pressing member is separated from the electrical connection member, allowing the pressing member to have a flexible pressing structure with adequate spring stroke while the electrical connection member maintains stable electrical characteristics independent of mechanical deformation.
Solution Approach 2:
The electrical connection member uses a flexible printed circuit board design where the conductive paths are configured to maintain constant electrical length even when the pressing member deforms. This allows the pressing member to achieve greater spring stroke without affecting electrical performance.
