Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired control signals are used to control solenoid valves, then reliable signal transmission is achieved, but installation complexity and maintenance costs increase due to cables and additional devices
Solution Approach 1:
The patent replaces the mechanical cable-based signal transmission system with a wireless communication system. The solenoid valve control unit receives control signals wirelessly through an antenna, eliminating the need for physical cables and magnetic switches. This substitution maintains signal transmission reliability while significantly reducing installation complexity and maintenance requirements.
Solution Approach 2:
The patent extracts and removes the cable and magnetic switch components from the solenoid valve control system. By taking out these additional devices, the system achieves simpler installation and maintenance while still providing reliable control signal transmission through wireless communication.
2Reliability
If cables are used for signal transmission in outdoor facilities, then signal transmission is achieved, but maintenance time and costs increase due to cable damage from moving objects or animals
Solution Approach 1:
The patent replaces the mechanical cable system with a wireless communication system that uses electromagnetic waves for signal transmission. This eliminates the vulnerability of cables to damage from moving objects or animals, thereby reducing maintenance time and costs while maintaining signal transmission reliability in outdoor facilities.
3Measurement precision
If wired control systems are used for multiple solenoid valves, then precise control is achieved, but installation costs increase due to extensive cabling requirements
Solution Approach 1:
The patent replaces the extensive cabling system with wireless communication technology. Each solenoid valve control unit receives control signals wirelessly, eliminating the need for extensive cables while maintaining precise control capability. This significantly reduces installation costs for systems controlling multiple solenoid valves.
4Productivity
If cut cable positions are not found, then system operation is maintained, but replacement costs and time increase as entire cables must be replaced
Solution Approach 1:
The patent replaces the cable-based system with wireless communication, eliminating the problem of cable cuts entirely. The wireless system maintains operation continuity without requiring cable replacement, as control signals are transmitted through electromagnetic waves that are not susceptible to physical damage.

AI summary
A solenoid valve controlled by wireless communication, in which the operation of the valve is controlled by wireless communication, thereby reducing costs and labors necessary for installation and maintenance. The solenoid valve includes a valve body having an inlet port, through which fluid is introduced, and an outlet port, through which fluid is discharged; a plunger movably mounted inside the valve body to open or close one or both of the inlet and outlet ports; a solenoid, which drives the plunger to a position, in which the plunger opens or closes one or both of the inlet and outlet ports, when electric power is supplied; and a communication module provided on the valve body. The communication module receives a wireless control signal transmitted from outside and controls the electric power supplied to the solenoid valve depending on the wireless control signal.
