Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic elements and magnetic sensors are used to detect faucet open state, then monitoring function is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the monitoring function from the faucet body and relocates it to the switch unit. The angle detector, microprocessor, and alert unit are integrated into the switch unit, separating the monitoring system from the main faucet structure. This reduces the complexity of the overall device while maintaining the monitoring function.
Solution Approach 2:
The switch unit is designed to serve multiple functions: it controls water flow by rotating the valve core and simultaneously performs monitoring functions through the integrated angle detector and microprocessor. This multi-functionality reduces the need for separate components, thereby simplifying the device structure.
2Reliability
If magnetic elements and magnetic sensors are disposed on grip and valve body respectively, then monitoring is enabled, but assembly difficulty increases due to precise registration requirements
Solution Approach 1:
The patent merges the angle detector, microprocessor, and alert unit into a single integrated monitoring device mounted on the switch unit. This consolidation eliminates the need for precise registration between separately disposed magnetic elements and sensors, significantly reducing assembly difficulty while maintaining monitoring accuracy.
3Reliability
If conventional monitoring device is used, then filter replacement tracking is achieved, but manufacturing cost increases
Solution Approach 1:
The patent employs an angle detector that is simpler and less expensive than magnetic sensors, integrated into the switch unit which is itself a relatively simple component. This approach uses cost-effective components to achieve the monitoring function, reducing overall manufacturing cost while maintaining the ability to track filter replacement needs.

AI summary
A faucet includes a faucet body, a switch unit and a monitoring device. The switch unit is coupled rotatably to the faucet body. The monitoring device is mounted to the switch unit and includes an angle detector, a microprocessor and an alert unit. The angle detector is for detecting angular rotation of the switch unit, and is for generating angle information. The microprocessor is for receiving the angle information, for recording a cumulative time period within which the switch unit is in an open state, and for calculating an outflow value accordingly. The microprocessor generates an alert signal for the alert unit upon determining that the outflow value has reached a predetermined threshold.
