Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual detection and intervention methods are used for contamination mitigation, then device complexity is reduced, but productivity and reliability of contamination response deteriorate
Solution Approach 1:
The system automatically detects contamination through sensors monitoring water quality parameters (turbidity, pH, ORP) and self-initiates mitigation actions by adjusting chemical dosing rates without requiring manual intervention. The controller autonomously responds to contamination events by modifying sanitizer and chlorine dioxide dosing based on real-time sensor data
Solution Approach 2:
The system continuously monitors water quality parameters through sensors and feeds this information back to the controller, which automatically adjusts chemical dosing rates. The closed-loop feedback mechanism enables real-time optimization of contamination mitigation by comparing actual water quality against target parameters and dynamically adjusting dosing accordingly
2Device complexity
If manual detection and intervention methods are used for contamination mitigation, then device complexity is reduced, but reliability of ensuring complete decontamination deteriorates
Solution Approach 1:
The system continuously monitors water quality parameters (turbidity, pH, ORP) and automatically adjusts chemical dosing rates based on real-time feedback. This closed-loop control ensures reliable decontamination by dynamically responding to contamination levels and maintaining water quality within safe parameters
Solution Approach 2:
The system replaces manual mechanical intervention with automated electronic sensing and control. Sensors detect contamination parameters and the controller automatically manages chemical dosing, eliminating human response delays and ensuring consistent, reliable decontamination through electronic automation
3Productivity
If automated contamination mitigation system is implemented, then productivity and reliability of contamination response are improved, but device complexity increases
Solution Approach 1:
The controller integrates multiple functions into a single device: it manages chemical dosing rates, processes sensor data from multiple sources (turbidity, pH, ORP sensors), stores operational parameters, and provides user interfaces for monitoring and control. This multi-functionality reduces the need for separate dedicated devices for each function
4Reliability
If continuous monitoring and automated response are implemented, then reliability of water quality safety is improved, but use of energy increases
Solution Approach 1:
The system employs periodic sampling of water quality parameters through sensors rather than continuous monitoring. The controller periodically reads sensor data and adjusts dosing rates accordingly, maintaining water quality safety through intermittent measurement and response rather than constant operation, thereby reducing energy consumption
