Battery Pack Reinforcement Supporting Member for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs for vehicles face challenges in structural stability and space utilization due to external impacts and varying environmental conditions, leading to potential cracks and reduced internal space efficiency.
Innovation Solution
Incorporating a reinforcement supporting member between battery module assemblies to enhance structural stability by supporting the cover member for the base plate, allowing for reduced constraints on mounting space and increased internal space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If battery module assemblies are mounted with large separation distance, then structural stability is improved, but internal space utilization is reduced
Solution Approach 1:
A reinforcement supporting member is introduced as an intermediary element positioned between battery module assemblies. This mediator provides structural reinforcement at the separation part, enabling stable mounting of the cover member while allowing closer spacing of battery modules, thus resolving the contradiction between structural stability and space utilization
Solution Approach 2:
The reinforcement supporting member is strategically positioned only at the separation part between battery module assemblies where structural support is needed. This localized reinforcement approach provides necessary structural stability without requiring increased separation distance throughout the entire battery pack, thereby optimizing internal space utilization
2Volume of moving object
If battery module assemblies are mounted close together, then internal space utilization is improved, but structural stability deteriorates
Solution Approach 1:
The reinforcement supporting member acts as a mediator that enables close mounting of battery modules while preventing structural deterioration. It provides localized support at critical separation parts, allowing the battery pack to maintain structural integrity even when modules are positioned close together for optimal space utilization
3Stability of the object's composition
If reinforcement supporting member is added, then structural stability is improved, but device complexity increases
Solution Approach 1:
The battery pack structure is segmented into distinct functional zones: battery module assemblies, separation parts, and reinforcement supporting members. This segmentation allows the reinforcement element to be independently positioned and integrated, providing structural stability while maintaining clear functional separation and manageable device complexity
