Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing fuse unit attachment structures risk damage when the battery terminal is inclined, as the resin housing of the fuse unit may hit the battery's lateral surface, requiring new designs for the battery terminal or fuse unit to prevent this, which is costly and not applicable to existing products.

Innovation Solution

A fuse unit attachment structure that includes a fuse bracket and a bracket connecting member, allowing the fuse unit to move perpendicular to the battery's lateral surface and restricting movement along the surface, using existing mounting holes on the battery, thus preventing the fuse unit from hitting the battery without modifying the existing terminal or fuse unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the battery terminal is mounted at an inclined angle from the proper mounting direction, then the installation flexibility is improved, but the resin housing of the fuse unit hits the lateral surface of the battery causing damage

Engineering Contradiction:

Improvemounting direction flexibilityVSAvoidfuse unit integrity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The fuse unit is nested within a protective bracket structure that is itself mounted on the battery terminal. The bracket acts as an outer container that shields the inner fuse unit from external impacts, allowing the assembly to accommodate inclined mounting angles without the fuse unit housing hitting the battery surface

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The protective bracket serves as an intermediary element between the fuse unit and the battery lateral surface. When the terminal is mounted at an incline, the bracket absorbs and redirects the potential impact forces, preventing direct contact between the fuse unit housing and the battery surface

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the structure of the battery terminal or fuse unit is modified to prevent the fuse unit from hitting the battery, then the reliability is improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:

Improvefuse unit protectionVSAvoidattachment structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The protective bracket is designed with multi-functionality: it provides mechanical protection for the fuse unit, enables accommodation of inclined mounting angles, and can be attached to standard battery terminals without modification. This universal design protects against hitting the battery while maintaining compatibility with existing terminal structures

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The protective bracket is designed as a simple, inexpensive component that can be easily manufactured and attached. Rather than modifying complex existing structures, the solution introduces a straightforward protective element that achieves reliability improvement at minimal cost and complexity

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

A fuse unit attachment structure includes a fuse bracket to be mounted on a fuse unit directly attachable to a battery and a bracket connecting member for connecting the fuse bracket to the battery. The fuse bracket has a unit supporting portion to support the fuse unit so as to be movable in a direction perpendicular to a lateral surface of the battery and a connecting member engaging portion to be engaged with the bracket connecting member so as to be movable in a direction along the lateral surface of the battery.
