Rotary Sealing Block Gap Adjustment for Pouch Battery Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secondary battery sealing apparatuses require frequent insertion and removal of shim rings to adjust the gap between sealing blocks, leading to inefficiencies and high costs due to the need for multiple shim rings of varying heights.
Innovation Solution
A gap adjustment device with supporting pieces and rotatable gap adjustment pieces having multiple height levels, allowing for stepwise adjustment of the gap between sealing blocks without the need for multiple shim rings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If shim rings of various heights are provided to adjust gaps between sealing blocks, then gap adjustment capability is improved, but device complexity and cost increase
Solution Approach 1:
The gap adjustment piece is designed to be rotatable relative to the sealing block, transforming a static set of multiple shim rings into a dynamic single component that can assume multiple positions. Each rotational position presents a different height profile to the supporting piece, enabling continuous gap adjustment without changing parts.
Solution Approach 2:
A single gap adjustment piece performs the function that previously required multiple shim rings of different heights. The circumferential surface with varying heights allows one component to provide multiple gap adjustment levels, eliminating the need for multiple specialized components.
2Adaptability or versatility
If shim rings are inserted or removed to adjust sealing portion thickness, then gap adjustment is achieved, but productivity decreases due to work discontinuity
Solution Approach 1:
The rotatable gap adjustment piece allows operators to switch between different gap settings by simply rotating the component in place, rather than stopping production to insert or remove shim rings. This dynamic adjustment mechanism maintains workflow continuity.
Solution Approach 2:
Multiple height profiles are pre-configured on the circumferential surface of the gap adjustment piece, allowing operators to select the appropriate gap setting in advance by rotating to the correct position, eliminating the need for preliminary selection and physical replacement of shim rings during the adjustment process.
3Adaptability or versatility
If multiple shim rings of varying heights are provided, then stepwise gap adjustment is enabled, but manufacturing cost increases
Solution Approach 1:
Multiple gap adjustment functions that previously required separate shim rings are merged into a single integrated gap adjustment piece. The component consolidates what would have been multiple discrete parts into one manufacturable element, reducing material costs, assembly complexity, and inventory requirements.
Solution Approach 2:
One gap adjustment piece provides the functionality of multiple shim rings through its circumferential height variations. This universal component eliminates the need to manufacture, store, and manage multiple specialized shim rings of different heights, significantly reducing overall manufacturing costs.
