Solution Overview

Problem

Conventional structures for fixing electrical junction boxes to batteries are not adaptable to different battery sizes and shapes, requiring separate designs for each battery type, limiting the universal use of the junction box.

Innovation Solution

A bracket system with a junction box fixing part and a battery fixing part, featuring slide locking walls and locking walls that can be adjusted to fit various battery sizes and shapes, allowing the same electrical junction box to be fixed to different batteries by changing the bracket configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the electrical junction box is fixed using conventional screw parts directly on the battery, then the fixing is simple, but the junction box cannot be commonly used across different battery sizes and shapes

Engineering Contradiction:
Improvecompatibility with different battery sizes and shapesVSAvoidfixing structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fixing structure is divided into two independent parts: a battery fixing part that attaches to the battery and a junction box fixing part that secures the junction box. This segmentation allows each part to be independently designed and adjusted for different battery configurations without redesigning the entire fixing mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bracket is designed with adjustable features including multiple through-holes at different positions and orientations, and locking walls that can engage with different battery surfaces. This universality enables the same bracket design to accommodate various battery sizes, shapes, and fixing positions, making the junction box commonly usable across different battery types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the fixing structure is designed to accommodate different battery sizes and shapes, then adaptability improves, but the number of parts and complexity increases

Engineering Contradiction:
Improvecompatibility with different battery configurationsVSAvoidnumber of fixing parts
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The battery fixing part and junction box fixing part are merged into a single integrated bracket structure. This combination reduces the total number of separate parts needed while maintaining the adaptability to different battery configurations through the bracket's adjustable features.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bracket incorporates adjustable and reconfigurable elements such as multiple through-holes that can be used in different combinations and locking walls that can be positioned to match different battery surfaces. This dynamic adaptability allows a single bracket design to serve multiple battery configurations without requiring multiple fixed parts.

Inventive Principle:
Principle #15Dynamics
