Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The manufacturing cost of batteries is high due to the need to redesign and remanufacture the housing when battery module specifications change, as the fixed positions of screw holes/bolts in the structural beam cannot accommodate variations in battery cell configurations.

Innovation Solution

A battery design that includes a positioning member connected to the structural beam, allowing the battery module to be positioned within the housing without redesigning the entire housing, by using interchangeable positioning members that adapt to changing specifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the housing is redesigned when battery module specifications change, then the battery module can be properly positioned in the housing, but the manufacturing cost increases

Engineering Contradiction:

Improveadaptability to battery module specification changesVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The housing is segmented into a main housing body and a separate positioning member. The positioning member is further segmented into a positioning plate and a positioning block. This segmentation allows the positioning member to be independently modified or replaced without redesigning the entire housing, enabling adaptation to different battery module specifications while avoiding high redesign costs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The positioning member is designed as a low-cost, easily replaceable component compared to the housing. When battery module specifications change, only the positioning member needs to be modified or replaced, not the entire housing. This approach treats the positioning member as a disposable or easily renewable part, significantly reducing manufacturing costs.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Manufacturing precision

If the positioning member is redesigned to accommodate different battery module specifications, then the positioning accuracy is maintained, but the device complexity increases

Engineering Contradiction:

Improvepositioning accuracyVSAvoidstructure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The positioning member is divided into a positioning plate and a positioning block, where the positioning plate provides a mounting surface and the positioning block provides the actual positioning function. This segmentation simplifies the design of each component while maintaining overall positioning accuracy, avoiding the need for a complex integrated structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The positioning member is designed with universal features that can accommodate different battery module specifications. The positioning plate can be configured with different positioning blocks for different module types, making the same basic structure adaptable to multiple specifications without requiring complete redesign, thus maintaining simplicity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
