Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional water filtration systems are used, then water purification function is provided, but real-time monitoring of water quality and filter element status is not available
Solution Approach 1:
The patent introduces a cloud management device as an intermediary between the water purification device and users/maintenance personnel. The cloud device receives water quality information from sensing circuits, processes it, and provides notifications, thereby enabling remote monitoring without significantly complicating the local purification system structure.
Solution Approach 2:
The system implements feedback loops where sensing circuits continuously monitor water quality parameters (TDS, temperature, pressure) and transmit this information to the cloud management device. The cloud device then provides feedback to users about filter element status and water quality, enabling timely maintenance decisions.
2Reliability
If conventional water filtration systems are used, then basic filtration is provided, but timely detection of equipment problems is not possible
Solution Approach 1:
The water purification device performs self-diagnosis through integrated sensing circuits that automatically monitor water quality parameters, filter element status, and equipment conditions. The system generates maintenance notifications automatically without requiring manual inspection, enabling timely detection of problems.
Solution Approach 2:
The patent replaces manual inspection methods with electronic sensing circuits and wireless communication systems. Sensors automatically detect water quality parameters (TDS, temperature, pressure) and transmit data via wireless modules to the cloud, eliminating the need for physical inspection of filter elements and equipment status.
3Loss of time
If manual maintenance scheduling is used, then maintenance can be performed, but response time to problems is delayed
Solution Approach 1:
The system performs preliminary actions by continuously monitoring water quality and filter element status in advance. When parameters indicate approaching maintenance thresholds, the cloud management device sends notifications to users before actual problems occur, enabling proactive maintenance scheduling and reducing response time.
