Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a vacuum hopper precharger is used to discharge gas from secondary batteries, then gas removal is achieved, but excessive time is required to create and release the vacuum
Solution Approach 1:
The heating part is activated before the vacuum degassing process to pre-warm the electrolyte and activate the battery chemistry. This preliminary heating ensures that gas bubbles are more readily formed and discharged during the vacuum phase, reducing the overall time required for effective degassing.
Solution Approach 2:
The system changes the temperature parameter of the electrolyte by applying heat through the heating part. This temperature increase modifies the physical and chemical properties of the electrolyte, enhancing bubble formation and discharge efficiency during vacuum degassing, thereby reducing the time required for effective gas removal.
2Productivity
If electrolyte is supplied to secondary batteries in the vacuum hopper precharger, then partial charging is achieved, but additional charging processes are still required
Solution Approach 1:
The vacuum hopper precharger is designed to perform multiple functions: vacuum degassing, heating, and complete electrolyte charging. By integrating the heating part and ensuring proper vacuum sealing, the device can now fully charge the electrolyte without requiring separate charging equipment, making the precharger a universal device for battery preparation.
Solution Approach 2:
The heating part pre-activates the electrolyte and battery components before the electrolyte is supplied and charged. This preliminary heating ensures that the electrolyte reaches optimal temperature for complete impregnation and charging during the vacuum phase, enabling full charging in a single operation rather than requiring follow-up charging processes.
3Productivity
If heating is applied to improve electrolyte activity, then gas and impurity discharge is enhanced, but energy consumption increases
Solution Approach 1:
The heating part operates continuously during the vacuum degassing process, maintaining optimal temperature throughout the entire operation. This continuous heating ensures sustained electrolyte activity and bubble discharge efficiency without requiring intermittent heating cycles, optimizing energy utilization while maintaining high productivity.
Solution Approach 2:
The system applies controlled temperature changes to the electrolyte through the heating part. By optimizing the heating temperature and duration parameters, the system achieves maximum electrolyte activity and gas discharge efficiency while minimizing energy consumption. The heating is applied only for the duration necessary to achieve complete degassing and charging.

AI summary
The present invention provides a heating tray for a vacuum hopper precharger, wherein a heating part is configured in a tray having a secondary battery mounted thereon to allow heat generated from the heating part to be circulated inside a vacuum hopper precharger and to be transferred to the entire secondary battery so that the activity of an electrolyte inside the secondary battery is improved, and according thereto, a large amount of residual gas and impurities can be discharged so as to increase purity of the secondary battery. Particularly, the secondary battery can be fully charged with an electrolyte inside the vacuum hopper precharger, thereby improving productivity compared to a conventional configuration in which a secondary battery is charged with an electrolyte at 60% to 70% inside a vacuum hopper precharger and then charged with a remaining charge amount in another process so as to be fully charged.
