Electrochemical Cell Mounting Assembly for Individual Cell Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assembling and disassembling electrochemical cells in electric vehicle batteries do not allow for individual cell extraction without dismantling a significant part of the assembly, making mechanical assembly and disassembly inefficient.
Innovation Solution
A support system with movable bars and protuberances that allow for the secure assembly and easy disassembly of electrochemical cells, using a clamping mechanism to hold cells in place and facilitate individual cell removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cells are arranged aligned on a flat support and held by parallel plates, then mechanical assembly is achieved, but individual cell extraction requires dismantling significant part of the assembly
Solution Approach 1:
The fixing system is segmented into multiple independent fixing devices (first and second fixing devices) that can operate independently on each cell. Each fixing device has movable bars with protuberances that engage with lugs on individual cells, allowing one cell to be released without affecting the fixation of other cells in the module.
Solution Approach 2:
The fixing system incorporates movable bars that can transition between different positions (first and second positions) to dynamically adjust the fixation state. The bars can move to engage or disengage from cell lugs, enabling easy individual cell removal while maintaining secure assembly during operation.
2Stability of the object's composition
If a fixed rigid support structure is used to hold cells, then mechanical stability is achieved, but disassembly complexity increases
Solution Approach 1:
The support structure incorporates movable bars that can dynamically transition between engaged and disengaged states. These bars maintain stable cell fixation during operation but can be easily moved to release individual cells, reducing disassembly complexity without compromising mechanical stability.
Solution Approach 2:
The protuberances on the movable bars act as intermediaries between the fixed support structure and the cell lugs. They provide a simple engagement interface that maintains stability when engaged but allows easy release when disengaged, simplifying the overall disassembly process.
