Rotary Gap Adjustment for Pouch Battery Sealing Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing secondary battery sealing apparatus requires frequent insertion or removal of shim rings to adjust the gap between sealing blocks, leading to inefficiencies and high costs due to the need for various shim ring heights for stepwise adjustments.
Innovation Solution
A gap adjustment device with supporting pieces on one sealing block and rotatably coupled gap adjustment pieces on the other, featuring multiple adjustment surfaces of different heights, allowing for simple stepwise adjustment of the gap between sealing blocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If shim rings with various heights are provided to adjust gaps between sealing blocks in a stepwise manner, then the gap adjustment precision is improved, but the device complexity and cost increase
Solution Approach 1:
The gap adjustment piece is designed with multiple adjustment surfaces of different heights integrated into a single component. This single piece can provide multiple gap adjustment levels (e.g., first gap, second gap, third gap) without requiring multiple separate shim rings, thus achieving multi-functionality and reducing device complexity while maintaining gap adjustment precision
Solution Approach 2:
Multiple adjustment surfaces that would traditionally require separate shim rings are merged into a single gap adjustment piece. This consolidation reduces the number of parts needed and simplifies the overall device structure while preserving the ability to adjust gaps in a stepwise manner with precise control
2Manufacturing precision
If shim rings are inserted or removed between sealing blocks for gap adjustment, then the gap between sealing blocks can be adjusted, but the productivity and operational continuity deteriorate
Solution Approach 1:
The gap adjustment piece is designed to be rotatably coupled to the sealing block rather than being fixed or requiring insertion/removal. By rotating the adjustment piece, different adjustment surfaces are brought into contact with the supporting piece, enabling dynamic gap adjustment during operation without stopping the sealing process, thus maintaining productivity and operational continuity
Solution Approach 2:
The gap adjustment piece is pre-configured with multiple adjustment surfaces at different heights before operation begins. This preliminary preparation allows the operator to simply rotate the piece to select the desired gap setting without needing to insert or remove components during operation, eliminating downtime and maintaining continuous productivity
3Adaptability or versatility
If multiple shim rings of different heights are used for gap adjustment, then various pouch thicknesses can be accommodated, but the cost increases
Solution Approach 1:
A single gap adjustment piece integrates multiple adjustment surfaces that correspond to different pouch thickness requirements. This universal component can accommodate various pouch thicknesses (first thickness, second thickness, third thickness) without requiring multiple separate shim rings, significantly reducing material costs and manufacturing complexity while maintaining full adaptability
Solution Approach 2:
Instead of creating multiple physical shim rings for different gap settings, the invention uses a single gap adjustment piece with multiple surfaces that replicate the functionality of multiple shims. This approach reduces the number of parts to be manufactured, inventoried, and managed, thereby lowering overall costs while preserving adaptability to different pouch thicknesses
