Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple storage tanks are provided and sequentially switched to supply electrolyte, then the electrolyte can be continuously supplied to use points, but the electrolyte remaining in the pipe is not subjected to temperature control and quality cannot be guaranteed
Solution Approach 1:
The system performs preliminary temperature control on the electrolyte in the storage tank before it is supplied through the pipe. By pre-heating or pre-cooling the electrolyte to the target temperature range (10-30°C) before supply, the system ensures that even the electrolyte that remains in the pipe during switching maintains its quality, eliminating the need to control temperature of stagnant pipe electrolyte.
2Temperature
If a return pipe is provided to return unused electrolyte to the storage tank, then temperature control can be maintained, but lot management becomes complicated when tanks are switched
Solution Approach 1:
The system performs preliminary temperature control on the electrolyte in the storage tank before supply, ensuring the electrolyte is pre-adjusted to the target temperature. This eliminates the need for a return pipe to maintain temperature, thereby simplifying the system structure and lot management while maintaining temperature control effectiveness.
3Productivity
If the electrolyte is stored in large-scale tanks for mass production, then the manufacturing capacity is increased, but the temperature control of delivered electrolyte becomes more difficult
Solution Approach 1:
The temperature control system is designed to control temperature in the storage tank rather than attempting to control temperature throughout the entire large volume of electrolyte or in the distribution pipes. By segmenting the control focus to the storage tank where heating/cooling can be efficiently applied, the system can maintain temperature control in large-scale operations without proportionally increasing complexity.
Solution Approach 2:
The system performs preliminary temperature adjustment in the storage tank before the electrolyte is distributed to use points. This pre-control approach ensures that the electrolyte maintains its target temperature (10-30°C) throughout the distribution process, making temperature control feasible even in large-scale manufacturing environments.
4Temperature
If the electrolyte is stored indoors with little temperature change, then temperature stability is maintained, but the system cannot meet the requirements of large-scale outdoor storage
Solution Approach 1:
The system performs preliminary temperature control in the storage tank, pre-adjusting the electrolyte to the target temperature range (10-30°C) before supply. This allows the storage tank to be located outdoors while maintaining temperature stability through active control, enabling large-scale storage capacity without requiring indoor facilities.

AI summary
An electrolyte supply system for supplying an electrolyte to a use point, includes: a receiving storage tank configured to store the electrolyte that has been delivered; a supply storage tank to which the electrolyte is transferred from the receiving storage tank; a temperature control device configured to control temperatures of the electrolyte in the receiving storage tank and that in the supply storage tank; and a supply pipe that is laid from the supply storage tank to the use point. The electrolyte supply system is highly safe because the storage tanks are disposed in an outdoor location, and furthermore, performs a temperature control process for the receiving storage tank before the electrolyte is transferred to the supply storage tank. Thus, it can supply the electrolyte to the use point 24 hours a day even with little temperature control in the supply storage tank.
