Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If an external power supply interface is added to the driving circuit, then the fan can be powered externally, but the device becomes more complex and inconvenient for use
Solution Approach 1:
The patent combines the power supply function with the existing fan structure by integrating an inductor into the fan blade assembly. The inductor serves dual purposes: it generates the magnetic field for fan operation and simultaneously acts as the power transmission component for the display function, eliminating the need for separate external power interfaces.
Solution Approach 2:
The inductor in the fan blade assembly performs multiple functions: it generates the rotating magnetic field for fan blade rotation and simultaneously transmits power wirelessly to the display circuit board. This multi-functionality reduces device complexity while maintaining power supply capability.
2Ease of operation
If a fixed driver program is pre-loaded in the driving circuit, then the display function is simplified, but the application becomes unitary and not adaptable to different needs
Solution Approach 1:
The patent transforms the static fixed program into a dynamic configurable system by adding a program loading interface. Users can selectively load different display programs (such as time display, date display, image display, or text display) according to their needs, making the system adaptable while maintaining ease of operation.
Solution Approach 2:
The patent pre-provides multiple display programs in a storage device and allows users to select and load them as needed. This preliminary preparation of multiple programs enables flexible adaptation without requiring complex real-time configuration, maintaining ease of operation while enhancing versatility.
3Adaptability or versatility
If the fan blade assembly is made more complex to include display functions, then the decoration effect is enhanced, but the manufacturing complexity increases
Solution Approach 1:
The patent merges the display function components (inductor, circuit board, light emitter array) with the existing fan blade assembly structure. The inductor is integrated into the fan blade, and the circuit board is installed on the fan blade assembly, allowing the display function to be added without completely redesigning the fan structure, thus controlling manufacturing complexity.

Implementation Method 1
An inductor set which is assembled by putting a emitter inductor and a receiver conductor close to each other but without contacting, whereof the said emitter inductor is firmly installed at the stator assembly
Implementation Method 2
A second circuit board which is firmly installed on top of the fan blade assembly, whereof its working power is generated after treating the high frequency electrical energy which is radiated by the emitter inductor and inducted by the receiver inductor

AI summary
A programmable controlled heat dissipating fan is comprised of a base, a stator assembly, a magnet frame assembly, a fan blade assembly, an inductor set, a first circuit board and a second circuit board. The stator assembly is firmly installed in the base, while the magnet assembly is sleeved into the periphery of the stator assembly. The fan blade assembly is rotated through the alternatively changing magnetic field produced by the stator winding and magnet frame, while the second circuit board is rotated and powered by electromagnetic coupling. The data content stored in the data repository is loaded by the microprocessor to drive the light emitting unit to display.
