Battery Cell Fixation Plate Structure for Vibration Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The service life of batteries is compromised due to unstable connection between battery cells and the case, leading to vibration and potential failure, as existing separation plates provide weak point connections that deform under stress.
Innovation Solution
A battery design featuring a case with a fixation plate that connects the first and second portions perpendicularly, with the fixation plate spaced apart to enhance connection strength and rigidity, and adhesive grooves for improved bonding, ensuring stable fixation of battery cells and reducing vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separation plate is used to connect battery cells to the case, then the battery cells can be fixed in position, but the connection strength is weak and the plate deforms under stress leading to unstable connection
Solution Approach 1:
The fixation plate is divided into multiple spacing structures that segment the single plate into several supported sections. This segmentation allows the plate to better distribute stress and prevents deformation, thereby improving connection stability and strength between battery cells and the case.
Solution Approach 2:
The fixation plate incorporates localized spacing structures at specific positions where support is needed. These local quality enhancements provide targeted reinforcement without requiring the entire plate to be thicker or more complex, optimizing the balance between connection strength and overall structure.
2Reliability
If the fixation plate connects both portions of the case, then the battery cells are securely fixed, but the structure becomes more complex
Solution Approach 1:
The fixation plate serves multiple functions simultaneously: it fixes battery cells in position, connects both portions of the case, and incorporates spacing structures for stress distribution. This multi-functionality reduces the need for additional separate components, thereby maintaining reliability while controlling structural complexity.
Solution Approach 2:
The spacing structures are integrated directly into the fixation plate rather than being separate components. This merging of functions into a single element simplifies the overall structure while maintaining the dual benefits of secure fixation and stress distribution.
