Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless connection is used for data transfer between components, then reliability and resistance to mechanical stress are improved, but electromagnetic interference and alignment sensitivity worsen
Solution Approach 1:
A magnetic coupling intermediary is introduced between the transmitting and receiving coils to mediate the wireless energy and data transfer. This magnetic intermediary enables reliable contactless power and data transfer while being insensitive to misalignment and displacement, thereby resolving the contradiction between reliability improvement and electromagnetic interference reduction
2Productivity
If NFC communication is used, then wireless data transfer is achieved, but bandwidth and data transfer rate are limited
Solution Approach 1:
The patent merges power transfer and data communication functions into a single wireless system using magnetic coupling. By combining these functions and utilizing higher frequency signals for data modulation on top of the power transfer carrier, the system achieves high bandwidth and fast data transfer rates without requiring separate communication hardware, thus improving productivity while managing device complexity
3Speed
If optical communication is used, then high speed data transfer is achieved, but alignment precision requirements and system complexity increase
Solution Approach 1:
The patent replaces the mechanical alignment system required by optical communication with a magnetic field-based wireless coupling system. The magnetic coupling inherently tolerates misalignment and displacement without requiring precise mechanical positioning or complex beam control mechanisms, thereby achieving high-speed data transfer while eliminating stringent manufacturing precision requirements
4Reliability
If galvanic connection is used, then data transfer reliability is maintained, but functionality per unit volume decreases due to increased contact requirements
Solution Approach 1:
The patent extracts the physical contact requirement from the data transfer system by implementing wireless magnetic coupling. This eliminates the need for multiple contact pads and switching leads, removing the constraint that forced increased device volume to achieve desired functionality, while maintaining connection reliability through contactless magnetic field coupling
