Battery Module Label-Handle Structure for Easy Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional secondary battery modules are cumbersome and difficult to exchange due to large handles, which increase the overall volume and interfere with devices, and require separate handle fabrication, making them hard to install and replace.
Innovation Solution
A secondary battery module design where a label serves as a handle, integrated with a case having insert openings, allowing the label to function as both a label and a handle, eliminating the need for a separate handle and reducing the module's volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a large handle is attached to the case for easy gripping, then the ease of operation is improved, but the volume of the secondary battery module increases and interference with devices occurs
Solution Approach 1:
The patent merges the label and handle into a single integrated component. The label is formed to include both a label body (for identification) and a handle portion (for gripping), eliminating the need for a separate handle attachment. This integration reduces the overall volume while maintaining ease of operation.
Solution Approach 2:
The label serves multiple functions: it provides identification information (traditional label function) and simultaneously serves as a gripping handle for easy exchange. This multi-functionality eliminates the need for a separate handle component, resolving the contradiction between ease of operation and volume.
2Ease of operation
If a large handle is attached to the case for easy gripping, then the ease of operation is improved, but the device complexity increases due to separate handle fabrication
Solution Approach 1:
The label and handle are combined into a single integrated component formed from the same material (e.g., paper, plastic, or metal). This eliminates the need for separate handle fabrication, assembly, and attachment processes, thereby reducing device complexity while maintaining ease of gripping.
Solution Approach 2:
The label performs dual functions as both an identification label and a gripping handle. This multi-functionality simplifies the overall structure by eliminating the need for separate handle components and their associated fabrication and assembly processes.
3Volume of moving object
If a small handle is used to reduce volume, then the volume of the secondary battery module is reduced, but the ease of operation deteriorates as it becomes difficult to grip
Solution Approach 1:
The label is designed with different local qualities: the label body portion is optimized for identification (flat, information-bearing surface), while the handle portion is specifically designed with extended length and appropriate dimensions for comfortable gripping. This local differentiation allows the handle to be optimally sized for gripping without increasing the overall module volume.
Solution Approach 2:
The handle portion of the label extends in the longitudinal direction (length dimension) rather than increasing the transverse dimensions. This dimensional approach allows the handle to achieve sufficient length for easy gripping while maintaining a compact overall volume of the secondary battery module.
