Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual monitoring and maintenance of filters is performed, then filter cleaning can be carried out, but operational staff time and system downtime increase
Solution Approach 1:
The system performs self-diagnosis and self-maintenance by automatically detecting filter clogging through flow rate monitoring and initiating cleaning cycles without human intervention. The control unit continuously monitors water flow, identifies when the filter requires cleaning, and automatically executes the cleaning process, eliminating the need for operational staff to manually check and maintain filters.
Solution Approach 2:
The system uses feedback from flow rate measurements to trigger automatic filter cleaning. The control unit receives continuous data from flow sensors, compares actual flow against baseline values to detect clogging, and automatically initiates cleaning cycles when thresholds are exceeded, creating a closed-loop maintenance system that responds to actual filter condition.
2Productivity
If automatic flow monitoring and automatic cleaning cycles are implemented, then operational staff time is reduced, but system complexity increases
Solution Approach 1:
The control unit performs multiple functions within a single integrated system: it monitors water flow rates, detects filter clogging conditions, determines optimal cleaning timing, controls the cleaning cycle execution, and logs system data. This multi-functionality reduces the need for separate dedicated devices for each function, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The system replaces manual mechanical monitoring and maintenance operations with automated electronic sensing and control. Flow sensors electronically monitor water flow instead of manual inspection, and the control unit automatically manages cleaning cycles instead of manual intervention, substituting mechanical human operations with electronic automation.
3Reliability
If filters are cleaned frequently to maintain efficiency, then filtration performance is maintained, but water consumption and energy use increase
Solution Approach 1:
The system performs preliminary detection of filter clogging through continuous flow rate monitoring before the filter completely fails or requires manual intervention. By detecting gradual degradation trends and predicting when cleaning is needed, the system can schedule maintenance optimally to prevent complete clogging while avoiding unnecessary frequent cleaning cycles, thus reducing water and energy consumption.
Solution Approach 2:
The system dynamically adjusts cleaning cycle parameters based on actual filter condition data. Instead of fixed frequent cleaning schedules, the control unit modifies cleaning frequency and duration according to real-time flow rate measurements and clogging detection, optimizing the balance between maintaining filtration efficiency and minimizing water/energy consumption.
