Connector Cap Elastic Impact Absorption for Battery Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with battery covers often experience unintended disengagement due to impact or fall, leading to battery exposure and potential power loss, as the battery cover can slide out, compromising convenience.
Innovation Solution
An electronic device design featuring a connector cap with a protrusion that engages with the battery cover's notch, preventing unintended slide movement by absorbing impact and ensuring the battery cover remains secured, thus eliminating the need for additional locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery cover is mounted using a simple sliding mechanism with convex and concave engagement parts, then the ease of operation is improved, but the reliability deteriorates because the battery cover can drop out due to impact or fall
Solution Approach 1:
The connector cap and battery cover are merged into a single integrated component. The connector cap serves dual functions: covering the connector and acting as a locking mechanism for the battery cover through its engagement parts (protrusion and recess) that interact with the battery cover's engagement parts to prevent unintended disengagement
Solution Approach 2:
The connector cap is designed with elastic material properties, allowing it to deform elastically under impact forces and then recover its original shape. This dynamic elasticity enables the connector cap to absorb impact energy while maintaining the locked state of the battery cover, preventing disengagement during drops or shocks
2Ease of operation
If the battery cover is designed to slide freely for easy mounting and removal, then the ease of operation is improved, but the stability deteriorates as the battery cover may slide in the opposite direction due to impact
Solution Approach 1:
The battery cover assembly is segmented into distinct functional parts: the battery cover itself for easy sliding installation, and the connector cap with engagement parts (protrusion and recess) that provide stable positioning. The engagement parts create a mechanical interlock that prevents reverse sliding while maintaining easy installation through the sliding motion
