Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If electromagnetic power supply structure is disposed in the fan (as disclosed in CN110083007A), then the holographic display assembly can be powered, but the common structure of the fan is greatly changed
Solution Approach 1:
The power supply system is segmented into two independent coils: a power supply coil fixed on the frame and a power receiving coil on the rotating fan blade. This segmentation allows the stationary frame to house the power source while the rotating blade receives power inductively, avoiding the need to integrate complex power supply structures into the rotating assembly and thus preserving the simplicity of the fan's mechanical structure.
Solution Approach 2:
A magnetic field is introduced as an intermediary between the power supply coil and the power receiving coil. The power supply coil generates a magnetic field that inductively transfers power to the power receiving coil without direct physical or electrical contact. This intermediary approach enables power transmission while maintaining structural simplicity and avoiding direct integration of power supply components into the fan blade.
2Use of energy by moving object
If driving assembly design is greatly changed (as disclosed in CN207609586U), then the holographic display assembly can be powered, but the design is not conducive to use and manufacture of existing holographic projection cooling fans
Solution Approach 1:
The power supply system is divided into a stationary power supply coil on the frame and a rotating power receiving coil on the fan blade. This segmentation allows the driving assembly to maintain its conventional design with minimal modifications, as the power transmission function is separated from the mechanical driving function. The existing driving assembly can continue to drive the fan blade rotation while the inductive power supply system operates independently.
Solution Approach 2:
The power supply coil on the frame serves multiple functions: it generates the magnetic field for inductive power transmission and can be integrated with the existing frame structure without requiring separate dedicated components. This multi-functionality approach allows the driving assembly to maintain its conventional design while accommodating the power supply function, improving ease of manufacture and use.
