Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a connection cable is used to energize the working module, then the motor can be reliably powered, but the convenience for IoT applications is reduced
Solution Approach 1:
The patent extracts the power transmission function from the mechanical connection cable by implementing wireless power transmission through electromagnetic induction. The working module is powered wirelessly through an induction element that receives power from the rotating magnetic element, eliminating the need for physical cable connections while maintaining reliable power supply for IoT applications
Solution Approach 2:
The patent replaces the mechanical connection cable system with an electromagnetic field-based wireless power transmission system. The magnetic element generates a rotating magnetic field that induces current in the induction element, substituting the mechanical power transmission through cables with electromagnetic power transmission through space
2Ease of operation
If wireless power transmission is implemented, then the convenience for IoT applications is improved, but the device complexity increases due to additional components
Solution Approach 1:
The patent implements multi-functionality by making the magnetic element serve dual purposes: it acts as both the rotor component that rotates to drive the fan and as the power transmission element that generates the electromagnetic field for wireless power supply. Similarly, the induction element serves both as a shield case component and as the power receiving element, reducing overall device complexity through functional integration
Solution Approach 2:
The patent merges the power transmission function with existing structural components. The magnetic element is integrated into the rotor assembly, and the induction element is incorporated into the shield case structure, combining multiple functions into unified components rather than adding separate dedicated parts for wireless power transmission
