Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual adjustment of angle stop is used, then device complexity is reduced, but measurement precision and control accuracy deteriorate
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated motorized adjustment device. The motor-driven mechanism automatically positions the angle stop valve based on feedback from flow sensors and control algorithms, eliminating the need for manual intervention while achieving precise control of valve position and water flow rate.
2Ease of operation
If manual adjustment of angle stop is used, then ease of operation is improved, but productivity and response time deteriorate
Solution Approach 1:
The system performs self-adjustment of the angle stop valve based on automated monitoring of water flow conditions. When abnormal conditions are detected (such as excessive flow rates or potential water damage scenarios), the control device automatically adjusts the valve position without requiring plumber intervention, enabling the system to service itself and respond immediately to conditions.
Solution Approach 2:
The patent implements a closed-loop control system where flow sensors continuously monitor water flow conditions and provide feedback to the control device. Based on this feedback, the controller automatically adjusts the angle stop valve position to maintain optimal flow rates or respond to abnormal conditions, eliminating the need for manual estimation and achieving precise, real-time control.
3Device complexity
If manual adjustment of angle stop is used, then device complexity is reduced, but adaptability to different conditions deteriorates
Solution Approach 1:
The patent transforms the static angle stop valve into a dynamic, automatically adjustable component. The motorized adjustment device can continuously modify the valve position in response to changing water flow conditions, enabling the system to adapt to various scenarios such as different flush volumes, maintenance requirements, or potential water damage prevention needs, rather than being fixed at a single manual setting.
