Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery modules with cartridge confinement suffer from vibration-induced movement of battery cells, leading to potential damage and reduced quality due to inadequate tolerance and assembly gaps, which can cause electrode lead connection issues.
Innovation Solution
A battery module design incorporating a frame cartridge assembly with a cell support member made of silicon, integrated through insert molding, which surrounds the battery cell to prevent movement and maintain assembly convenience, featuring various shapes such as circular, oval, rectangular, 'S', or repeatedly extending 'S' shapes to enhance support performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a predetermined gap is maintained between the battery cell and cartridge for assembly tolerance, then assembly convenience is improved, but vibration-induced movement of the battery cell increases
Solution Approach 1:
A cushioning member is introduced as an intermediary component between the battery cell and the cartridge. This cushioning member fills the gap required for assembly tolerance while providing vibration damping properties to prevent battery cell movement during operation, thus resolving the contradiction between assembly convenience and vibration resistance
Solution Approach 2:
The cushioning member is pre-installed in the cartridge before battery cell insertion, providing beforehand cushioning protection. This ensures that when the battery cell is assembled with necessary tolerance gaps, the cushioning member is already in position to prevent vibration-induced movement and damage to the battery cell and electrode leads
2Reliability
If the cartridge tightly confines the battery cell to prevent movement, then vibration resistance is improved, but assembly tolerance becomes difficult to accommodate
Solution Approach 1:
The cushioning member serves as a mediator that enables both tight confinement and assembly tolerance. It allows the cartridge to maintain a precise fit with the battery cell for vibration resistance while accommodating manufacturing tolerances through its compressible nature, facilitating easier assembly without compromising reliability
3Ease of manufacture
If the cartridge structure is simplified to reduce complexity, then manufacturing ease is improved, but vibration damping performance deteriorates
Solution Approach 1:
Rather than complicating the cartridge structure itself, a separate cushioning member is introduced as a specialized intermediary component. This allows the cartridge to remain simple and easy to manufacture while the cushioning member provides dedicated vibration damping functionality to protect against vibration damage
Solution Approach 2:
The vibration protection function is segmented from the cartridge structure and implemented through a separate cushioning member. This segmentation allows the cartridge to be manufactured simply while the cushioning member can be optimized specifically for vibration damping properties without affecting cartridge manufacturing complexity
