Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If acid cleaning is used to address bio-growth, then bio-fouling is removed, but the process becomes expensive, time-consuming, and hazardous
Solution Approach 1:
The system performs preliminary action by continuously generating biocide in advance to prevent bio-fouling accumulation, eliminating the need for periodic acid cleaning operations
Solution Approach 2:
The system converts the harmful effect of continuous biocide generation into a benefit by using flow sensors and control algorithms to optimize biocide production, preventing over-generation while maintaining effective bio-fouling prevention
2Reliability
If biocide generation is continuously maintained, then bio-fouling is prevented, but biocide overproduction occurs during flow transitions
Solution Approach 1:
The system uses flow sensors to provide real-time feedback on water flow conditions, and the controller adjusts biocide generation accordingly, reducing or stopping biocide production during flow transitions to prevent overaccumulation
Solution Approach 2:
The system dynamically adjusts biocide generation based on real-time flow conditions, transitioning from continuous generation to adaptive generation that responds to changing operational states
3Speed
If flow sampling frequency is increased to quickly detect flow transitions, then biocide generation can be adjusted faster, but system complexity and energy consumption increase
Solution Approach 1:
The system uses partial action by sampling flow at optimized intervals (e.g., every half second or second) rather than continuously, providing sufficient detection capability while reducing energy consumption and system complexity
