Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If slurry supply is interrupted at the target level to prevent excessive supply, then slurry level control precision is improved, but temperature stabilization time increases due to pipe length delay
Solution Approach 1:
The control system performs preliminary action by interrupting slurry supply in advance (at the first predetermined level) before the slurry actually reaches the target level in the supply tank. This anticipates the delay caused by pipe length and prevents excessive supply, while maintaining temperature stabilization efficiency.
Solution Approach 2:
The control system uses feedback from level detection to dynamically adjust supply interruption timing. By continuously monitoring the slurry level and using this feedback to control the supply interruption, the system optimizes both level precision and temperature stabilization without excessive supply.
2Productivity
If slurry supply starts at a level lower than target level to ensure continuous supply, then production continuity is improved, but temperature fluctuation increases due to excessive supply
Solution Approach 1:
The control system dynamically adjusts the slurry supply timing and duration based on real-time level detection. Instead of fixed supply schedules, the system adapts supply parameters to maintain optimal temperature while ensuring continuous production, resolving the contradiction between productivity and temperature stability.
3Device complexity
If proportional control is used for temperature adjustment during rapid temperature changes, then control simplicity is maintained, but temperature stabilization time becomes excessively long
Solution Approach 1:
The control system performs preliminary action by pre-adjusting supply parameters before rapid temperature changes occur. This anticipates temperature fluctuations and takes preventive measures, reducing stabilization time while maintaining relatively simple control logic.

AI summary
A method for controlling a supply amount of electrode slurry includes: (1) supplying the slurry from a first tank to a coater; (2) supplying the slurry from a second tank connected to the first tank to the first tank for a predetermined time, when the storage amount of the slurry in the first tank decreases and the level of the first tank reaches a first predetermined level; and (3) automatically interrupting the supply of the slurry from the second tank to the first tank after the predetermined time has elapsed.
