Terminal-Securing Auxiliary Member for Battery Fuse Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery terminal and battery-direct-attached type fuse unit attaching structures may lead to interference with the battery side surface if the terminal is inclined, causing damage to the fuse unit, and existing solutions require redesigning the terminal and fuse unit.
Innovation Solution
A terminal-securing auxiliary member with a terminal securing portion, a battery joining portion that engages with irregular height features on the battery surface, and a connecting portion with thin hinge portions that adjust the separation distance, preventing inclination and interference without modifying the existing terminal or fuse unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the battery terminal is attached without an auxiliary securing member, then the attaching structure is simple, but the terminal may become inclined causing the fuse unit to interfere with the battery side surface
Solution Approach 1:
The patent introduces a terminal-securing auxiliary member as an intermediary component between the battery terminal and the battery. This auxiliary member includes a terminal securing portion that fastens to the battery post and a terminal engaging portion that secures the battery terminal, preventing inclination and ensuring proper orientation without requiring complex redesign of the terminal or fuse unit itself
2Reliability
If the terminal-securing auxiliary member is added to prevent inclination, then the terminal orientation stability is improved, but the device complexity increases
Solution Approach 1:
The terminal-securing auxiliary member is segmented into distinct functional portions: a terminal securing portion for fastening to the battery post, a connecting portion for structural support, and a terminal engaging portion for securing the terminal. This segmentation allows each portion to perform its specific function efficiently while keeping the overall design manageable and not excessively complex
3Reliability
If the terminal structure is redesigned to prevent inclination, then the terminal orientation stability is improved, but the manufacturing cost and complexity increase
Solution Approach 1:
Rather than redesigning the terminal structure itself, the patent uses a terminal-securing auxiliary member as a mediator that attaches to the existing terminal and battery post. This approach maintains the original terminal design and manufacturing processes while achieving the desired orientation stability, avoiding the need for complex terminal redesign
Solution Approach 2:
The terminal-securing auxiliary member serves multiple functions: it secures the terminal to the battery post, prevents inclination, ensures proper orientation, and provides a mounting surface for the fuse unit. This multi-functionality eliminates the need for separate components or redesigns, simplifying both manufacturing and assembly
