Battery Cell Insulating Structure to Block Glue Flow at Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue with existing battery technologies is that glue tends to flow into the electrically connecting region at the end portion of the battery, affecting maintenance and leading to resource wastage due to bonding with the case, making after-sales service difficult.
Innovation Solution
A battery design featuring a first insulating component with a first and second extending portion, where the second extending portion is longer than the first, forming a gap that increases flow resistance and creates a glue receiving space, reducing the amount of glue that flows into the electrically connecting region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If glue is potted into the case to fix battery cells, then the battery cells are securely fixed, but glue flows into the electrically connecting region causing bonding with the case
Solution Approach 1:
The patent introduces an insulating component as an intermediary element between the battery cells and the case. This insulating component includes a substrate with extending portions that create a physical barrier and gap structure, preventing glue from directly reaching the electrically connecting region while still allowing battery cells to be fixed securely in position.
Solution Approach 2:
The insulating component is segmented into multiple functional portions: a substrate providing base insulation, extending portions creating gaps, and positioning structures. This segmentation allows the component to simultaneously perform multiple functions: fixing battery cells, preventing glue flow, and maintaining electrical isolation.
2Stability of the object's composition
If glue is used to fix battery cells, then positioning is achieved, but after-sales maintenance becomes difficult due to bonding
Solution Approach 1:
The insulating component serves as a removable intermediary that facilitates maintenance. During normal operation, it secures battery cells in position. During maintenance, the insulating component can be removed or accessed, allowing technicians to work on electrical connections without dealing with bonded glue, thus improving ease of repair.
3Object-generated harmful factors
If the insulating component has extending portions to prevent glue flow, then glue flow is reduced, but the structure becomes more complex
Solution Approach 1:
The insulating component is designed as a multi-functional element: the substrate provides electrical insulation, the extending portions prevent glue flow, and integrated positioning structures secure battery cells. By combining multiple functions into a single component, the patent reduces overall device complexity while achieving glue flow prevention.
