Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in securely mounting to substrates without damaging the contacts or the substrate, especially when requiring repeated mating and unmating, and they often suffer from cross-talk issues at high frequencies.
Innovation Solution
The electrical connector features a resilient and flexible mating end that flexes to apply pressure against substrate contact pads, defining a separable interface that allows for repeated mounting and unmounting without damage, and is designed to minimize multi-active asynchronous cross-talk by optimizing contact configuration and shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the electrical connector uses a rigid mounting structure to ensure stable connection, then connection stability is improved, but the connector cannot accommodate repeated mating and unmating without damage
Solution Approach 1:
The electrical contact incorporates a resilient portion that can dynamically flex between engaged and disengaged states. This dynamic characteristic allows the contact to withstand repeated mating and unmating operations while maintaining stable electrical connection during use, resolving the contradiction between connection stability and repeated mating capability
2Reliability
If the electrical contact applies high pressure against the contact pad to ensure reliable electrical connection, then electrical reliability is improved, but the substrate or contact pad may be damaged
Solution Approach 1:
The resilient portion is designed with specific material properties and geometric dimensions that allow it to apply optimized contact pressure. The pressure is sufficient to ensure reliable electrical connection but controlled to prevent substrate damage, achieving the balance between electrical reliability and substrate protection
3Device complexity
If the electrical connector uses traditional mounting methods to simplify the structure, then device complexity is reduced, but cross-talk at high frequencies cannot be effectively minimized
Solution Approach 1:
The resilient portion is strategically positioned between adjacent electrical contacts to provide localized shielding. This localized approach minimizes cross-talk between specific contacts while maintaining overall structural simplicity, effectively reducing multi-active asynchronous cross-talk without significantly increasing device complexity
