Solution Overview

Problem

Current methods for fixing wire harnesses in cell contact systems, such as using ties or wire harness grooves, increase production complexity, labor costs, and material requirements, leading to inefficiencies and higher defect rates.

Innovation Solution

A bracket with an elastic member and a position-limiting member that encloses a position-limiting space, allowing for adjustable fixation and anti-falling off of wire harnesses through elastic deformation, eliminating the need for ties and complex grooves.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ties are used to fix wire harnesses, then wire harnesses can be secured, but production processes increase and labor costs increase

Engineering Contradiction:
Improvewire harness fixationVSAvoidproduction efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The elastic member automatically secures wire harnesses through its elastic deformation properties without requiring manual tying operations. The bracket structure self-adjusts to accommodate and fix the wire harnesses, eliminating the need for separate tying processes and improving production efficiency while maintaining reliable fixation.

Inventive Principle:
Principle #25Self-service

2Reliability

If wire harness grooves are defined in plastic brackets, then wire harnesses can be fixed, but bracket structure complexity increases and mold-making difficulty increases

Engineering Contradiction:
Improvewire harness fixationVSAvoidbracket structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Instead of changing the bracket structure to include grooves, the invention changes the parameter of the fixing mechanism by using an elastic member that can deform to accommodate wire harnesses. This approach maintains the simplicity of the bracket structure while achieving reliable wire harness fixation through the elastic deformation capability of the member.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If wire harness grooves are defined in plastic brackets, then wire harnesses can be fixed, but material requirements increase and bracket weight increases

Engineering Contradiction:
Improvewire harness fixationVSAvoidmaterial requirements
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The invention extracts the wire harness fixation function from the bracket structure itself and transfers it to a separate elastic member. This allows the bracket to remain simple without integrated grooves, reducing material requirements and bracket weight, while the elastic member provides the necessary fixation capability through its elastic properties.

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If wire harness grooves are defined in plastic brackets, then wire harnesses can be fixed, but production costs increase

Engineering Contradiction:
Improvewire harness fixationVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention segments the wire harness fixation system into a separate elastic member and bracket structure. This segmentation allows the bracket to be manufactured simply without complex groove features, reducing mold-making costs and production expenses, while the elastic member can be independently produced and assembled to provide the required fixation function.

Inventive Principle:
Principle #1Segmentation

AI summary

The present application provides a bracket and a cell contact system assembly. The bracket includes a bracket body, an elastic member and a position-limiting member. A fixed end of the elastic member and a fixed end of the position-limiting member are assembled on the bracket body. The position-limiting member, the elastic member and the bracket body enclose to define a position-limiting space. An end of the elastic member away from the fixed end of the elastic member is a free end. An end of the position-limiting member away from the fixed end of the position-limiting member is a position-limiting end. A guiding opening defined between the free end of the elastic member and the position-limiting end of the position-limiting member is communicated with the position-limiting space. The guiding opening has a size being adjusted by changing a degree of deformation of the free end of the elastic member.
