Solution Overview

Problem

The existing CCS assembly process for battery modules is cumbersome, has a long processing cycle, and incurs high processing costs due to the need for different molds and UV glue application.

Innovation Solution

The integrated busbar is designed with a split structure comprising a mounting bracket and an installation bracket, allowing flexible adjustment and replacement of parts, reducing the complexity of installation and lowering replacement costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If an integral one-piece tray design is used for the integrated busbar bracket, then the structural strength and stability are improved, but the adaptability to different CCS structures is reduced and replacement costs increase

Engineering Contradiction:
Improvestructural strengthVSAvoidadaptability to different CCS structures
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The integrated busbar bracket is divided into multiple independent components including mounting brackets, installation brackets, and connection brackets. Each bracket can be independently selected and replaced based on different CCS structure requirements, thereby improving adaptability while maintaining structural integrity through proper connection designs.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If an integral one-piece tray design is used for the integrated busbar bracket, then the manufacturing simplicity is improved, but the ease of repair and replacement is reduced

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidease of replacement
Core Design Contradiction:
Ease of manufactureVSEase of repair

Solution Approach 1:

The bracket system is segmented into multiple replaceable components. When damage occurs to a specific part, only the damaged bracket needs to be replaced rather than the entire one-piece structure, significantly reducing repair time and costs while maintaining manufacturing simplicity for each individual component.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If different molds and UV glue are used for the CCS assembly process, then the manufacturing precision and protection are improved, but the processing complexity and cycle time increase

Engineering Contradiction:
Improveassembly precisionVSAvoidprocessing complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The mounting bracket and installation bracket are designed to work together as an integrated system that combines positioning, mounting, and protection functions. This merged design eliminates the need for separate UV glue application steps and multiple molding processes, reducing processing complexity while maintaining assembly precision through precise mechanical配合 between the bracket components.

Inventive Principle:
Principle #5Merging (Combining)
