Battery Module Housing Cushioning for Protruding Member Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery modules suffer from damage to protruding members, such as voltage detection connectors, due to external impacts, which occur when the electrode body and protruding members displace relative to the housing, leading to collisions that cause damage.
Innovation Solution
Incorporating an impact mitigation part, such as a slide member or deformation member, at the interface between the housing and protruding members to absorb or deflect the impact, preventing direct collision and subsequent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protruding member is arranged to protrude from the electrode body and be interposed in the housing, then the protruding member can perform its function (e.g., voltage detection), but when an impact is applied from the outside, the protruding member may collide with the housing and suffer damage
Solution Approach 1:
A cushioning member is provided between the protruding member and the housing to absorb impact energy before it reaches the protruding member. The cushioning member deforms under impact force, reducing the transmission of shock to the voltage detection connector and preventing damage while maintaining functional reliability.
Solution Approach 2:
The cushioning member acts as an intermediary element between the protruding member and the housing. It mediates the interaction during impact events, providing a buffer zone that protects the electrical connector from direct contact with the housing structure.
2Stability of the object's composition
If the electrode body and housing are rigidly structured to maintain position, then structural stability is improved, but under external impact, the rigid structure transmits full impact force to the protruding member causing damage
Solution Approach 1:
The cushioning member is locally positioned at the specific location where the protruding member interfaces with the housing, rather than making the entire structure flexible. This localized compliance maintains overall structural stability while providing impact protection only where needed.
Solution Approach 2:
The cushioning member is pre-positioned between the protruding member and housing to provide ahead-of-time protection. When impact occurs, the cushioning material already in place absorbs the shock, preventing force transmission to the protruding member while the rigid housing maintains its structural integrity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The impact mitigation part effectively reduces the likelihood of damage to protruding members by absorbing or deflecting the force of external impacts, ensuring the integrity of the battery module components.

AI summary
A battery module, including: an electrode body; a housing that covers a periphery of the electrode body; a protruding member that is disposed protruding from the electrode body and that is interposed in the housing; and an impact mitigation part at a position at which the housing and the protruding member face each other, the impact mitigation part mitigating an impact caused by a collision between the housing and the protruding member.
