Battery Module Cell Holder Blocking Structure for Empty Cell Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery modules face issues with leakage of urethane or silicone solutions due to missing cells in cell holders, which can lead to instability and reduced coupling strength between cells and wire bonding.
Innovation Solution
A battery module design that includes a cell holder with insertion regions and a blocking part that can be detachably attached to cover empty spaces, preventing leakage by using a combination of blocking blocks and sheets with adhesive properties to secure the solution and prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate cell holder is added to prevent leakage when a missing cell is present, then leakage prevention is improved, but device complexity increases
Solution Approach 1:
The blocking part is divided into a blocking body that covers the insertion hole and a blocking plate that seals the liquid solution, allowing each component to perform its specific function independently while simplifying the overall structure
Solution Approach 2:
The blocking part acts as an intermediary component inserted into the cell holder to seal empty insertion regions, preventing liquid solution leakage without requiring a separate additional cell holder structure
2Strength
If cells are firmly fixed in the cell holder, then coupling strength is improved, but ease of operation deteriorates due to difficulty in assembly and disassembly
Solution Approach 1:
The blocking part is designed to be detachably coupled to the cell holder, allowing it to be easily installed and removed based on whether insertion holes are empty, providing dynamic adaptability without compromising the firm fixation of cells during operation
Solution Approach 2:
The blocking part automatically serves its sealing function when inserted into the cell holder with empty insertion regions, eliminating the need for separate manual intervention to prevent leakage
