Solution Overview

Problem

Existing methods for mounting a 12V battery fuse box in vehicles are either space-consuming, expensive, or not robust enough, and are difficult to assemble and service.

Innovation Solution

A method involving a threaded connection between a fuse box and a vehicle battery using a fastening member that cuts thread in the battery cover, allowing for a secure, space-independent, and cost-effective mounting solution applicable to all H-type batteries, without requiring additional tooling or support structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional brackets or support structures are used to mount the fuse box, then the fuse box can be securely mounted, but the space required around the battery increases and the device complexity increases

Engineering Contradiction:

Improvemounting securityVSAvoidspace around battery

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The mounting function is merged with the battery cover itself. The cover is designed with integrated mounting holes and threaded inserts that directly provide the mounting capability, eliminating the need for separate brackets or support structures. This combines the protective cover function with the mounting function into a single integrated component.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The battery cover serves multiple functions: it protects the battery interior, provides structural support, and enables mounting of the fuse box through integrated threaded holes. This multi-functional design eliminates the need for additional dedicated mounting components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If additional brackets or support structures are used to mount the fuse box, then the fuse box can be securely mounted, but the device complexity and cost increase

Engineering Contradiction:

Improvemounting securityVSAvoidmounting structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The mounting capability is extracted directly into the battery cover design. Instead of adding external mounting components, the threaded holes and mounting features are built into the cover itself, removing the need for separate mounting hardware.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of manufacture

If the fuse box is mounted on the battery pole, then the mounting is simplified, but mechanical stress is introduced to the pole

Engineering Contradiction:

Improvemounting simplicityVSAvoidpole mechanical stress

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The mounting function is extracted from the battery pole and transferred to the battery cover. The cover is designed with dedicated mounting holes and threaded inserts that provide the mounting capability, removing the mechanical loading from the battery pole and its terminals.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The mounting function is separated from the battery pole structure and assigned to the battery cover. This segmentation allows the pole to maintain its primary electrical function without mechanical stress, while the cover handles the mounting function through its integrated threaded holes.

Inventive Principle:

Principle #1Segmentation

4Reliability

If conventional mounting methods are used, then the fuse box can be mounted, but the assembly and service difficulty increases

Engineering Contradiction:

Improvemounting capabilityVSAvoidassembly and service ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)
