Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible element is used to push the rod body in conventional magnetic control valves, then the valve can be controlled to open and close, but the compressed flexible element generates a reverse damper that causes shift phenomenon at the moving path, resulting in non-smooth operation
Solution Approach 1:
The patent removes the flexible element entirely from the system. Instead of using a flexible element to push the rod body, the invention uses a magnetic field generated by an electromagnetic coil to directly actuate the valve rod, eliminating the source of the reverse damper effect and achieving smooth operation.
Solution Approach 2:
The patent replaces the mechanical flexible element pushing system with an electromagnetic actuation system. The electromagnetic coil generates a magnetic field that directly moves the valve rod without mechanical contact or flexible elements, eliminating friction and reverse damper effects.
2Reliability
If many parts are assembled in conventional magnetic control valves, then the valve can achieve sealing and control functions, but the manufacturing costs and labor costs at installation increase
Solution Approach 1:
The patent combines multiple functions into fewer components. The valve body integrates the sealing surface and flow path, the electromagnetic coil serves as both the actuator and mounting structure, and the valve rod combines the magnetic material, sealing element, and actuating function in a single integrated component, reducing part count and assembly complexity.
Solution Approach 2:
The valve rod is designed with multi-functionality, incorporating magnetic material for electromagnetic actuation, sealing surfaces for leakage prevention, and structural support for the entire assembly. This multi-functional design eliminates the need for separate components and reduces manufacturing costs.
3Ease of operation
If higher lengths are reserved in structural design for controlling the valve in conventional magnetic control valves, then the valve can be fully actuated, but the size becomes extremely big and cannot be reduced to achieve light weight and small sizes
Solution Approach 1:
The patent transitions from linear actuation with long travel distances to radial or tangential actuation where the magnetic field acts perpendicular to the flow direction. This dimensional change allows full actuation with minimal displacement, dramatically reducing the overall valve size while maintaining complete opening and closing functionality.
Solution Approach 2:
The invention changes the actuation parameter from mechanical displacement over long distances to magnetic field strength variation. By controlling the electromagnetic coil current, the valve achieves full actuation through small physical movements, enabling compact design without sacrificing operational completeness.
Applied Scientific Principles

The design achieves smooth control motions, reduced manufacturing costs, and a compact size while maintaining effective sealing and operation, overcoming the limitations of prior art.
Implementation Method 1
an electromagnetic coil, wherein the electromagnetic coil is controlled by the magnetic pole switch to generate a positive pole magnetic field or a negative pole magnetic field
Implementation Method 2
The magnetic sucking element is contained inside the upper pipe body space without any movement. The valve rod is fit inside the lower pipe body space and can be properly displaced and regulated
Implementation Method 3
A bottom of the valve rod has a valve plug capable of completely sealing the valve of the rubber ring

AI summary
A magnetic control valve is to block an outlet end of a water inflow passage and an inlet end of a water outflow passage of a connection pipe by using a rubber ring. A valve of the rubber ring is opened or closed by a magnetic control switch. The magnetic control switch mainly takes a valve rod carrying permanent magnetic force that completely controls direction of electromagnetic pole as a power source for moving. When a valve plug at an end of the valve rod seals the valve, a metal plate capable of being sucked by magnetic force is combined with the rubber ring to allow both to generate magnetic sucking effect, thereby firmly closing.
