Battery Pack Housing With Integrated Cell Positioning and Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage power supplies have complex assembly processes, high costs, and low space utilization due to numerous structural parts and the need for extensive mounting space, leading to large product sizes.
Innovation Solution
The design includes a housing with cells and a busbar where electrodes are located on the same side, allowing for parallel and series connections, and a second housing with a positioning portion for direct cell insertion and fixation, reducing the number of parts and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a battery module is assembled from multiple parts (cell, cell support, busbar, collection plate, screw) and then fixed in the housing, then the battery pack can be assembled, but the assembly process becomes complex and cost increases
Solution Approach 1:
The patent combines the cell support and housing into an integrated structure, where the housing itself serves as the support structure. This merging eliminates the need for separate cell support components and reduces the number of parts that need to be assembled, thereby simplifying the assembly process and reducing manufacturing complexity while maintaining structural integrity
Solution Approach 2:
The housing is designed to perform multiple functions: it serves as both the protective enclosure and the structural support for the battery cells. This multi-functionality eliminates the need for dedicated support structures, reducing the number of components and simplifying the overall assembly process
2Quantity of substance
If mounting space is reserved for the battery module assembly, then the battery pack can be assembled, but the space utilization rate decreases and the overall product size increases
Solution Approach 1:
By merging the cell support function into the housing structure, the patent eliminates the need for additional mounting space that would be required for separate support structures. The housing walls themselves serve as the mounting surfaces, maximizing space utilization and reducing the overall product volume
