Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a motor is used to drive the fan blades, then the fan can achieve reliable rotation, but the structure becomes complex and difficult to disassemble for maintenance
Solution Approach 1:
The patent replaces the traditional motor-driven mechanical system with a magnetic field-based system. Coils generate a rotating magnetic field that directly acts on magnetic vanes attached to the blades, eliminating the need for a motor, output shaft, and associated mechanical components. This substitution resolves the contradiction by achieving reliable rotation through electromagnetic interaction while dramatically simplifying the mechanical structure.
Solution Approach 2:
The patent extracts and removes the motor component from the fan system. By taking out the motor and its associated mechanical drive train, the design eliminates the complex assembly that requires disassembly for maintenance. The magnetic vane rotor system operates without this extracted component, allowing direct access to blades for cleaning and maintenance.
2Ease of repair
If the protective cover is disassembled to access motor parts for cleaning, then maintenance can be performed, but the process becomes complicated and time-consuming
Solution Approach 1:
The patent extracts the magnetic rotor assembly from the protected mechanical enclosure. Since there is no motor to protect, the magnetic vanes and blades can be accessed directly by removing only the protective cover, without the need to disassemble motor housings or electrical components. This extraction principle significantly reduces maintenance time and complexity.
Solution Approach 2:
The fan assembly is segmented into easily separable components: the protective cover, the magnetic rotor assembly with blades, and the coil assembly. This segmentation allows the protective cover to be removed independently for maintenance access, while the magnetic rotor components can be further separated if needed, reducing the time and complexity of maintenance operations.
3Ease of operation
If motor components are exposed for user maintenance, then cleaning can be performed, but electric shock risks increase
Solution Approach 1:
The patent replaces the electric motor with a magnetic field generation system where coils create a rotating magnetic field. The magnetic vanes respond to this field without direct electrical contact. This substitution eliminates exposed electrical components that users might accidentally contact during maintenance, removing the electric shock hazard while maintaining cleaning accessibility.
Solution Approach 2:
The magnetic field acts as an intermediary between the electrical coils and the mechanical blades. The coils generate the magnetic field, which then drives the magnetic vanes without direct electrical-mechanical contact points exposed to users. This intermediary field-based interaction removes hazardous electrical components from user-accessible areas while preserving the ability to clean and maintain the blades.

AI summary
A fan assembly includes a fan cover. The fan cover is provided with a vane assembly and is fixed by a rotating shaft, which includes blades and magnetic vanes arranged along its outer contour. The coils are evenly arranged along the fan cover. The magnetic rotor blade and the alternating magnetic field generated by the coils can drive the blades to rotate, and the rotation speed can be adjusted by changing the speed of the alternating magnetic field. The coils are fixedly installed in the outer cover of the fan, and the vane assembly is only installed by the rotating shaft, which can easily disassemble from the vane assembly. The structure is simple and has higher reliability. So, it is not easily damaged, and has a longer service life. The fan assembly can be completely waterproof, so that the product can be used in high humidity and even water.
