Battery Case Insulating Member Prevents Short Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in preventing short circuits between the elastic member and the battery module or protective circuit module in battery packs, which is difficult due to the elastic member's separation during attachment and detachment, affecting the stability and safety of the battery pack.
Innovation Solution
An insulating member is formed between the elastic member and the battery module, and the protective circuit module, preventing direct contact and ensuring the elastic member's proper operation to avoid short circuits, thereby enhancing the stability and safety of the battery pack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the elastic member is positioned between the front case and the battery module to enable attachment and detachment, then the ease of operation is improved, but the risk of short circuit between the elastic member and battery module increases
Solution Approach 1:
An insulating member is introduced as an intermediary component positioned between the elastic member and the battery module. This insulating member prevents direct contact between the conductive elastic member and the battery module, thereby eliminating the short circuit risk while preserving the attachment and detachment functionality of the elastic member.
2Reliability
If the insulating member is added between the elastic member and battery module to prevent short circuits, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The insulating member is integrated with the front case structure, merging the insulation function into the existing case design. This integration approach adds the necessary insulation capability while minimizing the increase in overall device complexity, as the insulating member becomes part of the case assembly rather than a separate independent component.
3Ease of operation
If the elastic member is allowed to separate during operation to maintain flexibility, then the ease of operation is improved, but the stability of the battery pack deteriorates
Solution Approach 1:
The insulating member acts as a mediator that maintains a controlled separation between the elastic member and the battery module. This ensures the elastic member can flex and move during attachment and detachment operations while preventing excessive separation or displacement that would compromise battery pack stability.
Solution Approach 2:
The insulating member is designed as a thin film or flexible structure that accommodates the elastic member's movement while maintaining its insulating function. This flexible insulating structure allows the elastic member to operate freely within defined limits while preserving battery pack stability and preventing short circuits.
