Solution Overview
Problem
Existing winders face difficulties in quickly and easily injecting electrolytic solution into the gap between separating films and electrodes in battery or capacitor production, often resulting in air entry and wrinkle formation on the films, which complicates the process and requires extensive manual effort.
Innovation Solution
A winder equipped with a chamber that uses vacuum pumps to maintain low air pressure, allowing the winding process to occur in a vacuum environment, ensuring that the gap between the films and electrodes remains sealed, and an electrolytic solution can be naturally injected into this vacuum state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If winding is performed in atmospheric conditions, then the winding process is simple and quick, but air enters the gap between separating films and electrodes causing wrinkles and excess current
Solution Approach 1:
The patent applies vacuum environment (inert atmosphere principle) to prevent air from entering the gap between separating films and electrodes during winding. By maintaining negative pressure in the winding chamber, the system eliminates harmful air infiltration that causes wrinkles and electrical defects, while still allowing high-speed automated winding to proceed efficiently.
2Reliability
If manual air removal work is performed during electrolytic solution injection, then air can be removed from gaps, but the process becomes troublesome and requires extensive man-hours
Solution Approach 1:
The patent performs air removal in advance by maintaining vacuum conditions during the winding process itself. This preliminary action eliminates the need for subsequent manual air removal operations during electrolytic solution injection, reducing both process complexity and time requirements while ensuring reliable air-free gaps.
Solution Approach 2:
The vacuum system automatically removes air from the winding process without requiring manual intervention. The negative pressure environment self-regulates to prevent air entry into gaps, eliminating the need for separate air removal steps and extensive manual work during later processing stages.
3Manufacturing precision
If vacuum pumping is applied during winding, then air is prevented from entering gaps and wrinkles are prevented, but the device complexity increases
Solution Approach 1:
The patent introduces a vacuum chamber with pumping equipment to create an inert (vacuum) environment during winding. This prevents air from entering the gap between separating films and electrodes, eliminating wrinkles and electrical defects. The added complexity of the vacuum system is justified by the significant improvement in product quality and elimination of subsequent air removal operations.
