Dynamic Connector Assembly for Impact-Resistant Electrical Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard electronic connectors are prone to damage from high impacts and loads, leading to reduced service life due to rigid connections that break under stress, especially in rugged and mobile environments.
Innovation Solution
A dynamic connector design featuring a movable pluggable connector relative to a housing, with protrusions and slots, and conductive contact springs that absorb impact while maintaining electrical communication, allowing the connector to move laterally and vertically without disconnecting from the substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid connection is used between the connector and substrate, then structural stability is improved, but the connector becomes prone to damage from high impacts and loads
Solution Approach 1:
The connector employs a dynamic design where the connector body can move relative to the substrate through protrusions sliding in slots, transforming the rigid static connection into a dynamic system that adapts to impact forces while maintaining electrical connectivity
Solution Approach 2:
The connector changes its positional parameters under impact by allowing the connector body to displace relative to the substrate, absorbing impact energy through controlled movement rather than rigid resistance
2Reliability
If the connector is made movable to absorb impact, then impact resistance is improved, but electrical connection stability may deteriorate
Solution Approach 1:
The protrusions and slots act as intermediary elements that guide and constrain the movement of the connector body, ensuring that displacement occurs in a controlled manner while maintaining continuous electrical contact with the substrate
Solution Approach 2:
The spring-loaded protrusions provide pre-compression force that cushions the connector body against impact forces, absorbing shock before it reaches the electrical contacts and maintaining stable connection during movement
3Reliability
If spring-loaded protrusions are added to enable movement, then impact absorption is improved, but device complexity increases
Solution Approach 1:
The spring-loaded protrusions serve multiple functions simultaneously: they provide electrical contact, enable guided movement, absorb impact forces, and maintain connection stability, eliminating the need for separate components for each function
