Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional manual inspection methods are used for fluid control valve switching time, then the inspection process is simple, but the measurement precision and reliability are insufficient
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated electronic inspection system. The inspector device uses electronic components including a counting unit, limited switches, timer, and display to automatically measure and record valve switching times, eliminating manual measurement and significantly improving precision while providing systematic automation.
Solution Approach 2:
The patent introduces limited switches as intermediary devices that detect the position of the travel pointer and trigger the timing function. These switches serve as mediators between the mechanical valve movement and the electronic timing system, enabling precise automated measurement without direct mechanical contact.
2Reliability
If automated inspection devices are implemented, then the measurement precision improves, but the device complexity and cost increase
Solution Approach 1:
The inspector device is designed as a multi-functional integrated system that can measure both turn-on and turn-off times of fluid control valves using the same hardware components. The counting unit, timer, and display serve multiple functions including time measurement, data processing, and result presentation, reducing the need for separate specialized devices.
Solution Approach 2:
The inspection system is designed to be self-contained and self-operating. The device automatically initiates timing when the travel pointer activates the limited switch, automatically records the switching time, and displays the result without requiring external intervention or complex external systems, making the system self-sufficient.
3Productivity
If manual timing methods are used, then the device complexity is low, but the productivity and inspection efficiency are reduced
Solution Approach 1:
The inspection device is pre-configured with the basic data of the fluid control valve before inspection begins. The counting unit and timer are ready to automatically capture switching times without requiring manual setup or configuration during the inspection process, enabling rapid consecutive inspections and improving productivity.

AI summary
A method of inspecting switching time with fluid control valve used for inspecting operating time to turn-on or turn-off a valve door of a fluid control valve is disclosed. The method comprises following steps: firstly provide an inspector with a counting unit, a timer, a first limited switch and a second limited switch. The counting unit electrically connects to the timer and a pneumatic module of fluid control valve, the first limited switch and second limited switch connect to the timer, and the first limited switch contacts the rod of the fluid control valve rod. Then, input basic data of corresponding fluid control valve, which comprises operating conditions of the fluid control valve. Next, activate the pneumatic module and start to time, and the axial shift generated by the rod of the fluid control valve triggers the second limited switch to stop timing. Lastly, record and display operating time.
