Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional valve structure with flexible element is used to control water flow, then the valve can be opened and closed, but the compressed flexible element generates reverse damper causing non-smooth movement of the rod body
Solution Approach 1:
The patent removes the flexible element from the valve structure entirely. Instead of using a flexible element to push the rod body, the invention uses a magnetic field generated by an electromagnetic coil to directly drive the rod body, eliminating the source of reverse damper effect and achieving smooth valve operation.
Solution Approach 2:
The patent replaces the mechanical flexible element pushing system with an electromagnetic driving system. The electromagnetic coil generates a magnetic field that directly acts on the magnetic rod body, substituting mechanical contact and elastic deformation with non-contact electromagnetic force, thereby eliminating reverse damper and friction.
2Reliability
If multiple parts are assembled to create a conventional magnetic control valve, then the valve can function, but the manufacturing cost and labor cost increase
Solution Approach 1:
The patent combines multiple components into an integrated structure. The valve body, seat, and magnetic control elements are merged into a unified design where the rod body itself is magnetic and directly interacts with the electromagnetic coil, reducing the number of separate parts and assembly steps while maintaining full valve functionality.
Solution Approach 2:
The rod body serves multiple functions: it acts as both the mechanical component that opens/closes the valve and as the magnetic element that responds to the electromagnetic field. This multi-functionality reduces the need for separate magnetic components and simplifies the overall structure.
3Reliability
If conventional valve structures are designed with sufficient length for control mechanisms, then the valve can operate reliably, but the overall size becomes extremely large and heavy
Solution Approach 1:
The electromagnetic driving system replaces lengthy mechanical linkages and control mechanisms with a compact magnetic field generation system. The electromagnetic coil and magnetic rod body can achieve full control stroke in a much shorter distance compared to mechanical spring or cam-based systems, significantly reducing valve size and weight.
Solution Approach 2:
The invention changes the fundamental operating parameter from mechanical displacement through long linkages to magnetic field-driven direct displacement. This allows the same control function to be achieved with much shorter dimensional parameters, creating a compact and lightweight valve design.

AI summary
A magnetic control valve is to block an outlet end of a water inflow passage (41) and an inlet end of a water outflow passage (42) of a connection pipe (40) by using a rubber ring (50). A valve of the rubber ring is opened or closed by a magnetic control switch. The magnetic control switch mainly takes a valve rod (90) 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 (501) capable of being sucked by magnetic force is combined with the rubber ring (50) to allow both to generate magnetic sucking effect, thereby firmly closing.
