Battery Terminal Cover With Tool Restricting Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery terminal covers do not effectively prevent tools from damaging vehicle bodies during battery maintenance, as the tool's rotation can contact and harm the vehicle when loosening or tightening bolts.
Innovation Solution
A battery terminal cover with a movable portion coupled via a hinge, featuring a tool restricting portion that interferes with the tool before it can contact the vehicle, and a lateral displacement restricting mechanism to ensure the tool cannot rotate further, combined with an angle setting portion to support the movable portion at an acute angle, allowing the tool restricting portion to be positioned safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the movable portion is opened to allow tool rotation for battery maintenance, then the ease of operation is improved, but the tool may contact and damage the vehicle body
Solution Approach 1:
The tool restricting portion acts as an intermediary element between the tool and the vehicle body. It is positioned to interfere with the tool's rotation path, preventing the tool from contacting the vehicle body while still allowing the movable portion to open for maintenance operations.
Solution Approach 2:
The tool restricting portion is pre-positioned to counteract the potential harmful action of tool rotation before it can occur. By being placed in the tool's rotation path, it preemptively stops the tool from reaching a position where it could damage the vehicle body.
2Reliability
If the tool restricting portion is positioned to effectively block tool rotation, then the reliability of protection is improved, but the pressing force may displace the movable portion from the body
Solution Approach 1:
The ceiling plate is segmented into a fixed ceiling plate and a movable ceiling plate that are coupled via a hinge. This segmentation allows the movable ceiling plate to rotate independently while the fixed ceiling plate remains stationary, providing a stable reference point for the tool restricting portion.
Solution Approach 2:
The hinge coupling is pre-designed to allow rotational movement while maintaining connection between the fixed and movable ceiling plates. This preliminary structural arrangement ensures that the movable portion can rotate for maintenance access while remaining connected to the stable body structure.
3Ease of operation
If the movable portion is designed to open fully for tool access, then the ease of operation is improved, but the tool restricting portion cannot be effectively positioned
Solution Approach 1:
The movable portion is designed to be dynamic, allowing it to rotate between a closed position (for protection) and an open position (for maintenance access). The tool restricting portion is positioned on the movable portion, so it moves with it, ensuring continuous effectiveness regardless of the movable portion's angle.
Solution Approach 2:
The tool restricting portion serves as a moving intermediary that maintains its protective function throughout the range of motion. As the movable portion rotates to allow tool access, the tool restricting portion rotates with it, continuously blocking the tool's path to the vehicle body.
