Battery Cell Case Tool-Free Assembly via Integrated Holders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery cell cases require separate fastening tools and processes, increasing assembly time and reducing productivity due to asymmetrical case plates that need to be manually fastened with screws or bolts.
Innovation Solution
The battery cell case design features symmetrical or asymmetrical case plates with integrated holders and locking mechanisms, allowing for tool-free assembly by inserting and locking the plates together, reducing the need for separate fastening means and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional battery cell cases use asymmetrical case plates with separate fastening means (screws or bolts), then the structural integrity and protection of the battery cell is ensured, but the assembly time increases and productivity decreases due to manual fastening processes
Solution Approach 1:
The patent combines the case plate structure with integrated holders that serve dual functions: protecting the battery cell and fastening the case plates together. The holders are formed as integral parts of the case plates, eliminating the need for separate fastening means and manual assembly processes while maintaining structural integrity.
2Reliability
If conventional battery cell cases use separate fastening means (screws or bolts), then secure coupling of case plates is achieved, but the device complexity increases due to additional fastening components and assembly steps
Solution Approach 1:
The case plates are designed with integrated holders that are formed as single integral structures. This merging of the holder and case plate eliminates multiple separate components (case plates, holders, screws, bolts) and simplifies the overall device structure while maintaining secure coupling through the integrated holder design.
3Productivity
If symmetrical case plate structures with integrated holders are used, then tool-free assembly is enabled and productivity increases, but the manufacturing precision requirements increase to ensure proper alignment and coupling
Solution Approach 1:
The patent employs asymmetrical holder structures where the front case plate holder and rear case plate holder have different configurations. This asymmetry includes different positioning of coupling protrusions and recesses, which guides the assembly process and ensures proper alignment during tool-free assembly, thereby reducing the impact of manufacturing precision variations.

AI summary
Disclosed herein is a battery cell case. The battery cell case includes a front case plate and a rear case plate which are separably coupled to each other. The structures of the front and rear case plates are symmetrical structures, so that the battery cell case can be easily assembled in such a way that the front and rear case plates are coupled to each other with the battery cell disposed therebetween and are fastened to each other by holders fitted over the opposite ends of the case plates. In another embodiment, the structures of the front and rear case plates may be asymmetrical structures so that the front and rear case plates can be coupled with each other in an insert coupling manner without using a separate tool or fastening means.
