Vehicle Battery Frame Structure With Reusable Cross-Frame Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery frame structures for vehicles require a large number of components, which hinders resource reusability and recycling, as they often need additional restraining members and protective elements to secure battery modules from external impacts.
Innovation Solution
A battery frame structure featuring removably fastened cross frames within the battery case that also serve to restrain battery cells between end plates, reducing the number of components and facilitating recycling by eliminating the need for separate restraining members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate restraining members and protective members are used to secure battery modules, then protection from external impact is improved, but the number of components increases and resource reusability deteriorates
Solution Approach 1:
The patent combines the protective member and restraining member into a single integrated protective member that performs both functions. The protective member directly restrains the battery module without requiring separate restraining members, thereby reducing component count while maintaining protection effectiveness.
Solution Approach 2:
The protective member is designed to serve multiple functions simultaneously: it protects the battery module from external impact and restrains the battery module in place. This multi-functional design eliminates the need for separate restraining members and brackets, reducing overall device complexity.
2Reliability
If multiple separate members (brackets, restraining members, protective members) are used, then protection and restraint functions are achieved, but resource reusability and recycling efficiency deteriorate
Solution Approach 1:
By merging the protective member and restraining member into a single component, the patent enables the entire assembly to be reused as one unit. This integration allows the protective member to be recovered and reused when the battery module is replaced, improving resource efficiency.
Solution Approach 2:
The integrated protective member is designed to be recoverable and reusable. When the battery module is replaced, the protective member can be removed and reused for the next battery module, reducing material waste and improving sustainability.
3Reliability
If brackets are used to suppress relative movement between battery modules, then protection from external input is improved, but the number of members increases
Solution Approach 1:
The protective member is designed to perform both protection from external input and suppression of relative movement between battery modules. This eliminates the need for separate brackets, as the protective member itself provides the necessary restraint function.
