Engineering Contradiction Analysis
1Productivity
If the water level in the electrode boiler chamber is high, then the heating efficiency is improved, but the current flowing through water increases rapidly causing power supply overload
Solution Approach 1:
The control apparatus continuously monitors the current flowing through water in the electrode boiler chamber and automatically adjusts the water level by controlling the intake and exhaust valves. When current exceeds a predetermined threshold, the system reduces water level to decrease current flow, preventing power supply overload while maintaining efficient operation within safe parameters.
Solution Approach 2:
The system dynamically changes the water level parameter in the electrode boiler chamber based on real-time current measurements. By adjusting the water level (a physical parameter), the system controls the contact area between water and electrode bars, thereby regulating the current flow to prevent overload while maintaining heating efficiency.
2Reliability
If the water level is lowered to reduce current flow, then power supply overload is prevented, but the heating efficiency decreases
Solution Approach 1:
The control apparatus operates in periodic cycles, adjusting the water level up and down based on current thresholds. When current exceeds the upper threshold, water level is reduced; when current falls below the lower threshold, water level is increased. This periodic adjustment maintains the system within optimal operating ranges, preventing overload while maximizing heating efficiency.
Solution Approach 2:
The system dynamically adjusts the water level rather than maintaining a fixed level. The intake and exhaust valves are controlled in real-time based on current measurements, allowing the water level to adapt continuously to changing operating conditions. This dynamic control ensures both power supply stability and heating efficiency are optimized simultaneously.
