Bus Bar Grip Structure for Easy Battery Module Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical energy storage modules lack an efficient method for separating bus bars from the energy storage devices, making recycling and maintenance difficult.
Innovation Solution
Incorporating a grip part, either as a projection or penetration hole, into the bus bar design allows for easy separation by pulling the grip part, facilitating the disassembly of the module and improving recyclability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the bus bar is integrated into the electrical energy storage module without a separation structure, then the structural integrity and electrical connection are improved, but the difficulty of separation and recyclability worsen
Solution Approach 1:
The bus bar is segmented into a main body portion and a grip part. The grip part is designed as a separate functional element that protrudes from the bus bar surface, allowing it to be pulled independently. This segmentation enables the bus bar to maintain structural integrity during operation while facilitating easy separation during maintenance or recycling by applying force to the grip part.
2Ease of manufacture
If the bus bar is designed with a simple linear shape, then the manufacturing complexity is reduced, but the ease of separation and handling worsens
Solution Approach 1:
The bus bar features a local quality change where the grip part has a different geometric configuration compared to the main body. The grip part includes protrusions or extended sections that provide optimal gripping surfaces, while the main body maintains a simple linear shape for easy manufacturing. This local differentiation improves handling and separation ease without significantly complicating the overall manufacturing process.
