Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual replacement of filter components is used, then system complexity is reduced, but maintenance efficiency and water quality consistency deteriorate
Solution Approach 1:
The system automatically monitors component degradation through sensors and triggers replacement without user intervention. The control circuit detects when filters or storage tanks need replacement and initiates the process autonomously, eliminating manual checking while maintaining high maintenance efficiency.
Solution Approach 2:
Sensors continuously monitor water quality parameters and component status, providing feedback to the control circuit. This feedback loop enables the system to detect degradation and automatically initiate replacement, resolving the contradiction between simplicity and maintenance efficiency.
2Device complexity
If manual monitoring of component degradation is used, then device complexity is reduced, but water quality reliability deteriorates
Solution Approach 1:
Manual monitoring is replaced with electronic sensors and control circuits that automatically detect component degradation. This substitution improves water quality reliability through continuous automated monitoring while keeping the system relatively simple through straightforward sensor-control architecture.
3Productivity
If automated component replacement is implemented, then maintenance efficiency is improved, but device complexity increases
Solution Approach 1:
The system performs self-monitoring and self-initiated replacement of components. Sensors automatically detect when filters or storage tanks need replacement and trigger the replacement process without requiring user intervention, achieving high maintenance efficiency with a relatively simple automated architecture.
4Reliability
If continuous monitoring of water quality parameters is implemented, then water quality reliability is improved, but use of energy increases
Solution Approach 1:
The system uses periodic sampling and event-triggered monitoring rather than continuous high-energy monitoring. Sensors check water quality parameters at intervals or when specific conditions are met, maintaining reliable water quality detection while minimizing energy consumption compared to continuous real-time monitoring.
