Asymmetric Cell Mounting Jig for Error-Tolerant Battery Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery cell mounting process often results in damage to secondary battery cells due to thickness differences and position errors between the cells and the mounting jig, leading to potential electrolyte leaks and insulation failures.
Innovation Solution
A cell mounting jig with a base and vertically extended supports, where the second support is taller than the first and both are thinner at the top than the bottom, allowing for a gradual guide for cell insertion, and a cell alignment device with a jig connection member to stabilize the jigs and facilitate precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional cell mounting jig with uniform support height is used, then the mounting process is simple, but the battery cell appearance is damaged due to interference from thickness differences and position errors
Solution Approach 1:
The patent applies asymmetry by configuring the mounting jig with two supports of different heights: a first support and a second support that is higher than the first support. This asymmetric height configuration allows the higher second support to prevent interference with the battery cell appearance while the lower first support provides stable mounting, thereby resolving the contradiction between maintaining cell integrity and keeping the structure simple.
2Ease of operation
If the support thickness is uniform throughout, then the manufacturing is simple, but the cell insertion is difficult due to position errors and thickness variations
Solution Approach 1:
The patent applies local quality by making the support thickness non-uniform: the supports are thicker at the lower portion and thinner at the upper portion. This local variation in thickness creates a tapered structure that guides the cell during insertion, making the insertion process easier despite position errors, while maintaining relatively simple manufacturing requirements.
3Manufacturing precision
If the mounting jig does not have alignment features, then the device is simpler, but the cell positioning precision is insufficient due to position errors
Solution Approach 1:
The patent applies curvature by designing the supports with a tapered profile (thinner at the top, thicker at the bottom). This curved/tapered geometry naturally guides the cell into the correct position during insertion, providing alignment functionality without requiring additional complex alignment features, thus improving positioning precision while maintaining device simplicity.

AI summary
Discussed is a cell mounting jig that can include a base, a first support vertically extended from a side of the base, and a second support vertically extended from an opposite side of the base and spaced a predetermined distance apart from the first support, the first support and the second support facing each other. The second support can be extended higher than the first support.
