Solution Overview

Problem

Existing battery contact members in hybrid and electric vehicles suffer from poor assembly and separation of insulating and elastic components due to physical forces, leading to degraded compression performance and increased risk of separation during vehicle travel.

Innovation Solution

A battery contact member design featuring an insulating member with extension parts and guide bosses to securely couple with elastic members, ensuring firm contact between the cooling block and battery, and incorporating ribs for insulation and assembly tolerance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the insulating member and elastic member are assembled as separate components, then the assembly flexibility is improved, but the assembly stability deteriorates due to separation under physical forces

Engineering Contradiction:
Improveassembly flexibilityVSAvoidassembly stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The insulating member and elastic member are integrated into a single unified component. The elastic member is formed as an integral part of the insulating member, eliminating the need for separate assembly while maintaining both flexibility and stability. This resolves the contradiction by combining the benefits of separate components (flexibility) with the advantages of integrated structures (stability under vibration and physical forces).

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If the elastic member is fixed to the insulating member through slitting, then the assembly ease is improved, but the compression performance deteriorates due to hole formation

Engineering Contradiction:
Improveassembly easeVSAvoidcompression performance
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

Instead of joining components through slitting in the planar dimension, the elastic member is integrated into the insulating member through three-dimensional forming processes. The elastic member extends from the insulating member as a continuous structure, maintaining compression performance while achieving assembly ease through molded integration rather than post-assembly slitting operations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If the elastic member is assembled at only one point, then the device complexity is reduced, but the reliability deteriorates due to easy separation under vibrations

Engineering Contradiction:
Improveassembly complexityVSAvoidresistance to separation
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The elastic member is divided into multiple segments or zones of attachment along its length. Instead of a single assembly point, the elastic member is integrated with the insulating member at multiple locations, distributing the attachment points to prevent separation under vibration while maintaining relatively simple overall structure. This segmentation approach enhances reliability without significantly increasing device complexity.

Inventive Principle:
Principle #1Segmentation
