Fuse Unit Holding Mechanism Reduces Battery Post Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fuse units mounted on vehicles do not effectively suppress the load acting on battery posts, leading to inefficiencies in connection and potential damage.
Innovation Solution
A fuse unit design featuring a fusible link connected to a battery terminal with a holding mechanism and locking mechanism that includes a base portion, holding portion, and locking claws, which are configured to securely attach the fusible link above the battery post, reducing the load on the post and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the battery terminal is directly connected to the battery post, then the connection is simple, but the load acting on the battery post cannot be suppressed
Solution Approach 1:
The connection structure is divided into multiple components: a holding mechanism with base portion and holding portion, a locking mechanism with locking claws, and a fusible link. This segmentation allows the load to be distributed across multiple attachment points rather than concentrated on the battery post alone, reducing the force on the post while maintaining connection simplicity.
Solution Approach 2:
The holding mechanism acts as an intermediary between the battery terminal and the battery post. It includes a base portion that contacts the post standing surface and a holding portion that secures the fusible link, thereby mediating the connection and suppressing the direct load on the battery post.
2Force
If the fusible link is held above the post standing surface, then the load on the battery post is suppressed, but the attachment structure becomes more complex
Solution Approach 1:
The holding mechanism integrates multiple functions into a single structure: the base portion provides mounting on the post standing surface, the holding portion secures the fusible link, and the side wall provides structural support. This merging reduces the number of separate components needed, simplifying the attachment structure while maintaining the load-suppressing configuration that holds the fusible link above the post standing surface.
Solution Approach 2:
The holding mechanism serves multiple purposes simultaneously: it anchors the fusible link above the post standing surface to reduce load, provides a mounting interface on the post standing surface, and includes side walls that offer structural support and positioning. This multi-functionality achieves the desired load suppression without requiring additional separate components.
3Stability of the object's composition
If the holding mechanism includes a side wall extending toward the lower side, then the attachment stability is improved, but the manufacturing complexity increases
Solution Approach 1:
The side wall is integrated into the holding mechanism as a unified structure rather than a separate component. This merging allows the side wall to be formed simultaneously with the base portion and holding portion during manufacturing, improving attachment stability through the extended side wall structure without significantly increasing manufacturing complexity.

Function Achieved in This Case
The design effectively suppresses the load on battery posts, ensuring reliable attachment and protection of the fusible link, even in constrained spaces, thereby improving the overall performance and durability of the fuse unit.

AI summary
A fuse unit includes a fusible link, a holding mechanism, and a locking mechanism. The fusible link is connected to a battery terminal and includes a fusible element that melts when an overcurrent flows through the fusible link. The holding mechanism includes a base portion disposed between a post standing surface of a battery housing and the battery terminal in a state where the battery terminal is fastened to a battery post provided on the post standing surface, and a holding portion that is formed next to the base portion and that holds the fusible link above the post standing surface. The locking mechanism locks the holding mechanism onto the post standing surface. With this configuration, the fuse unit can suppress a load acting on the battery post.
