Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electromagnetic coupling is used to couple adjacent primary conductive paths, then power can be supplied from one power supply device to multiple primary conductive paths, but phase synchronization control is required to prevent magnetic field cancellation, increasing system complexity
Solution Approach 1:
The patent replaces electromagnetic coupling with electrostatic coupling to transfer power between primary conductive paths. By using an electrostatic coupler instead of magnetic coupling, the system eliminates the need for phase synchronization control while maintaining the ability to supply power from one power supply device to multiple primary conductive paths, thus reducing control complexity while preserving adaptability
2Device complexity
If electrostatic coupling is used to couple non-contact power supply devices, then phase synchronization is not required and control is simplified, but power transfer between devices must be achieved through electrostatic field
Solution Approach 1:
The patent introduces an electrostatic coupler as an intermediary component to enable power transfer between primary conductive paths. The coupler uses electrostatic field coupling through capacitive coupling to transfer power without requiring phase synchronization, simplifying control while maintaining acceptable power transfer efficiency through the intermediary electrostatic coupling mechanism
