Solution Overview
Problem
Conventional fuse units with fixed fusible links are not versatile enough to accommodate battery posts at different positions, requiring new designs for battery terminals and mounting members.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the fusible link is fixed to the mounting member, then the assembly structure is simple and stable, but the fuse unit cannot be assembled to batteries with battery posts at different positions, reducing versatility
Solution Approach 1:
The fusible link is designed to be movable relative to the mounting member in the planar direction, transforming the static fixed structure into a dynamic adjustable structure. This allows the fusible link to adapt its position to match different battery post locations while maintaining a relatively simple overall assembly structure.
Solution Approach 2:
The mounting member is divided into distinct functional regions: a positioning portion that provides lateral constraints and a fastening portion that provides axial constraints. This segmentation allows independent optimization of positioning and securing functions, enabling the fusible link to be positioned accurately without requiring complete redesign of the entire mounting structure.
2Adaptability or versatility
If the fusible link is made movable in the planar direction, then versatility is improved for different battery post positions, but the assembly structure becomes more complex
Solution Approach 1:
The fusible link is designed to be movable relative to the mounting member in the planar direction, transforming the static fixed structure into a dynamic adjustable structure. This allows the fusible link to adapt its position to match different battery post locations while maintaining a relatively simple overall assembly structure.
Solution Approach 2:
The positioning portion of the mounting member features an asymmetric U-shaped cross section with specific dimensional constraints that provide lateral positioning in one direction while allowing movement in the planar direction. This asymmetric design enables selective constraint that achieves versatility without requiring complex mechanisms.
3Reliability
If a new battery terminal and mounting member design is created for each battery post position, then precise fitting is achieved, but design time and cost increase
Solution Approach 1:
The mounting member is designed as a universal component that can accommodate battery posts at different positions through the movable fusible link mechanism. The positioning portion with its specific dimensional constraints provides reliable electrical connection for various battery configurations without requiring custom-designed mounting members for each position, significantly reducing design time and cost.
Solution Approach 2:
Instead of changing the physical structure of the mounting member for different battery post positions, the invention changes the positional parameter of the fusible link relative to the mounting member. This parameter adjustment approach maintains connection reliability while avoiding the need for multiple mounting member designs.

AI summary
A fuse unit includes a battery terminal to be electrically connected to a battery post of a battery, a fusible link having a fuse that is electrically connected to the battery terminal and is melted due to overcurrent, and a mounting member to be mounted to the battery, in which the fusible link to which the battery terminal is assembled is arranged. The fusible link is arranged to be movable with respect to the mounting member in a planar direction parallel to a plane from which the battery post of the battery protrudes.
