Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired power supply with electric brush contact points is used, then power transmission is achieved, but the power supply circuit breaks and service life reduces due to high-speed rotation friction
Solution Approach 1:
The patent replaces the mechanical wired power supply system with electric brush contact points with a wireless electromagnetic induction power transmission system. The transmitter coil on the stator and receiver coil on the rotor enable contactless power transfer, eliminating mechanical friction, noise, and contact wear, thereby resolving the contradiction between reliability and harmful friction factors.
2Power
If electric brush contact points are set on the fan shaft, then power supply is achieved, but friction noise is generated affecting user experience
Solution Approach 1:
The patent substitutes the mechanical electric brush contact system with an electromagnetic induction system. The transmitter coil mounted on the stator and receiver coil on the rotor enable wireless power transmission, completely eliminating mechanical contact and associated friction noise while maintaining effective power supply to the rotating fan blades.
3Power
If wired power supply circuit is used, then power transmission is achieved, but the circuit breaks under high-speed rotation conditions
Solution Approach 1:
The patent replaces the wired power supply circuit with a wireless electromagnetic induction power transmission system. The transmitter coil on the stator and receiver coil on the rotor enable contactless power transfer, eliminating the mechanical wear and circuit breakage issues that occur under high-speed rotation while ensuring stable and continuous power transmission.
4Productivity
If continuous high-speed rotation is required, then cooling efficiency is improved, but heat generation increases affecting service life
Solution Approach 1:
The patent replaces the mechanical electric brush power transmission system with wireless electromagnetic induction, eliminating frictional heat generation. The transmitter and receiver coils enable efficient power transfer without mechanical contact, reducing heat buildup and allowing the fan to operate at high speeds for improved cooling efficiency without excessive temperature rise.
