Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If uncontrolled supply and discharge of fresh water, salt water, non-permeating water, and mixed water are used, then the system operation is simple, but energy usage becomes excessive and energy generation becomes unbalanced
Solution Approach 1:
The control unit receives detection signals from detection units that monitor flow rates and pressures of fresh water, salt water, non-permeating water, and mixed water. Based on this feedback information, the control unit adjusts the operation of regulation units to optimize energy generation while preventing excessive energy usage, thus resolving the contradiction between energy efficiency and control complexity.
Solution Approach 2:
The system uses detection units to automatically monitor and provide information about the actual operation state to the control unit, which then automatically adjusts regulation units without requiring external intervention. This self-regulating mechanism reduces energy waste while maintaining manageable system complexity through automated control.
2Reliability
If uncontrolled discharge of non-permeating water and mixed water occurs, then the operation procedure is simple, but system reliability deteriorates due to potential system failures
Solution Approach 1:
Detection units continuously monitor flow rates and pressures of non-permeating water and mixed water, providing real-time feedback to the control unit. The control unit uses this information to adjust regulation units, ensuring that discharge operations remain within safe and efficient parameters, thereby improving system reliability while maintaining automated operation.
Solution Approach 2:
The system replaces manual operation and monitoring with automated detection units and control units that use electronic sensing and processing to monitor and regulate water discharge. This substitution of mechanical/manual control with electronic automation improves reliability by providing consistent, precise control while simplifying operation through automated decision-making.
3Productivity
If uncontrolled supply of fresh water and salt water is used, then the system is easy to operate, but energy generation efficiency decreases due to generation imbalances
Solution Approach 1:
Detection units monitor the flow rates and pressures of fresh water and salt water supply, providing real-time feedback to the control unit. The control unit adjusts the operation of regulation units based on this feedback to optimize the balance between energy input and output, thereby improving energy generation efficiency while maintaining automated supply control.
Solution Approach 2:
The system automatically monitors and adjusts fresh water and salt water supply through detection units and control units that work together to optimize energy generation. This self-regulating mechanism improves productivity by ensuring optimal supply conditions while reducing the need for manual intervention, effectively balancing efficiency gains with operational simplicity.
