Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a buoy mechanism with a lever is used to control water flow, then the water level control function is achieved, but the shaft of the lever is prone to mechanical damage reducing usage life
Solution Approach 1:
The patent replaces the traditional mechanical buoy-lever system with an electromagnet-based magnetic control system. The electromagnet uses magnetic field forces to control the opening and closing of the water flow path, eliminating the need for a mechanical lever shaft that is prone to damage. This substitution of mechanical components with electromagnetic components directly resolves the contradiction by improving reliability while avoiding mechanical strength limitations.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the control signal and the water flow regulation. Instead of direct mechanical contact through a lever shaft, the electromagnet generates a magnetic field that acts on magnetic components (such as a magnetic ball or valve) to control water flow. This intermediary magnetic field transmission mechanism eliminates mechanical stress on lever shafts, thereby improving durability and usage life.
2Device complexity
If a traditional buoy control mechanism is used, then water flow control is achieved, but the structure becomes complex and requires additional mechanical components
Solution Approach 1:
The patent simplifies the overall structure by replacing the complex mechanical buoy-lever-shaft assembly with a more compact electromagnet-based system. The electromagnet, combined with magnetic control components, achieves the same water flow control function with fewer moving parts and less mechanical complexity, while maintaining or improving control reliability through electromagnetic actuation.
3Ease of operation
If mechanical components are used for water path control, then the control mechanism is established, but mechanical stress leads to component damage
Solution Approach 1:
The patent replaces mechanical control components with an electromagnet-based system that uses magnetic fields to control water path opening and closing. This eliminates mechanical stress on control components while maintaining ease of operation through electrical control signals. The magnetic control mechanism provides durable, stress-free actuation that improves component longevity while preserving operational simplicity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The magnetic control assembly effectively prolongs the usage life of the water controller by preventing mechanical damage to the lever and allowing for precise water level management, while also simplifying the structure and saving resources by eliminating the need for a pumping device.
Implementation Method 1
a magnetic control assembly, a water trough, and an electromagnet; when the electromagnet is in a power-on state, a path between the first water outlet and the water inlet is in a connected state under a control of the control assembly; and when the electromagnet is in a power-off state, the path between the first water outlet and the water inlet is in a blocking state under the control of the control assembly
