Battery Cover Regulating Portion Prevents Terminal Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery covers can cause damage to the battery post and terminal when the terminal cover part is excessively closed due to interference, leading to potential damage during assembly and disassembly.
Innovation Solution
A battery cover design featuring a regulating portion on the terminal cover part that contacts the upper surface of the battery to prevent excessive closure, combined with an operating portion for opening and closing, which includes an extension portion to manage the movement and prevent interference with the battery post and terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal cover part is made movable for opening and closing, then ease of operation is improved, but reliability deteriorates due to potential excessive movement causing damage
Solution Approach 1:
The patent applies preliminary anti-action by providing a regulating portion that prevents excessive movement of the terminal cover part before damage can occur. The regulating portion includes a regulating surface that contacts the battery upper surface to limit the closing movement, and a regulating groove that guides the movement, thereby preventing the harmful effect of excessive movement that would cause interference with the battery post or terminal.
2Manufacturing precision
If the terminal cover part is designed to close completely, then manufacturing precision is improved, but object-affected harmful factors worsen due to interference with battery components
Solution Approach 1:
The regulating portion is designed to prevent excessive movement before it causes harmful interference. The regulating surface and regulating groove work together to limit the closing movement to a safe range, ensuring that the terminal cover part does not contact the battery post or terminal even when closed, thereby eliminating the harmful effect while maintaining precise manufacturing.
3Ease of operation
If the terminal cover part is made extendable beyond the recess, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The terminal cover part is segmented into functional zones: the main cover portion within the recess, the extension portion protruding from the recess, and the regulating portion with regulating surface and groove. This segmentation allows the extension to provide ease of operation while the regulating portion controls the movement to prevent excessive extension, managing complexity through functional division.
