Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-capacity battery module assemblies face challenges in maintaining a compact structure while ensuring stable fixation of unit modules, leading to increased volume and complexity due to the need for multiple combining members like extension bolts and brackets.
Innovation Solution
A battery module assembly design that incorporates a module array body with unit modules closely attached on all sides, supported by a combination-type module housing with a first space for support and a second space for fixation, allowing for compact integration by eliminating separate fixing spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple combining members (extension bolts, brackets, combining bars) are used to maintain structural stability of large-capacity battery module assembly, then the structural stability is improved, but the device complexity and volume increase
Solution Approach 1:
The patent integrates the fixing bracket directly into the module housing structure, merging two separate components (housing and fixing mechanism) into a single integrated unit. This eliminates the need for separate extension bolts and combining bars, thereby reducing device complexity while maintaining structural stability of the battery module assembly
Solution Approach 2:
The module housing is designed to serve multiple functions: it provides structural enclosure for the battery modules and simultaneously acts as the fixing mechanism through the integrated fixing bracket. This multi-functionality reduces the number of separate components needed, simplifying the manufacturing process while ensuring stable fixation
2Stability of the object's composition
If multiple combining members are used to fix unit modules in large-capacity battery module assembly, then the fixation stability is improved, but the volume of the assembly increases due to additional space required for engagement
Solution Approach 1:
The fixing bracket is integrated into the module housing, eliminating the need for separate fixing components that would require additional engagement space. This merging of functions reduces the overall volume of the battery module assembly while maintaining stable fixation of unit modules through the housing's own structural features
3Volume of stationary object
If a compact structure with simple combination of constituent elements is desired, then the volume is reduced, but the fixation stability of unit modules deteriorates
Solution Approach 1:
The module housing performs dual functions as both the structural enclosure and the fixing mechanism. By making the housing itself the fixing element through the integrated bracket, the design achieves compact volume without compromising fixation stability, as the housing's inherent structural strength is utilized for both protection and securement
4Strength
If extension bolts and combining bars are used to combine unit modules and external members, then the structural integrity is improved, but the number of parts increases leading to increased assembly complexity
Solution Approach 1:
The patent consolidates multiple separate fastening components (extension bolts, combining bars) into a single integrated fixing bracket that is part of the module housing. This merging maintains structural integrity through the housing's own rigidity and the bracket's design, while dramatically reducing the number of parts from multiple separate components to a unified structure
