Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If in-band wireless power transfer communication is used, then wireless power transfer is achieved, but data transmission speed is limited to 1-3 kilobytes per second
Solution Approach 1:
The patent introduces a wired connection as an intermediary communication channel that operates in parallel with the wireless power transfer system. This wired connection serves as a mediator for high-speed data transfer, while the wireless in-band connection handles power transfer and basic communication, thus resolving the speed limitation without compromising wireless power functionality
Solution Approach 2:
The communication system is segmented into two separate channels: a wired connection for high-speed data transfer and a wireless in-band connection for power transfer and control communications. This segmentation allows each channel to optimize its function independently, with the wired channel handling bulk data transfer and the wireless channel maintaining power transfer operations
2Speed
If wired connections are used for faster data transmission, then data transfer speed improves, but system complexity increases due to requiring both wired and wireless connections
Solution Approach 1:
The wireless power transfer system is designed with multi-functionality to handle both power transfer and basic communications through the in-band wireless channel, while the wired connection serves as a supplementary high-speed data channel. This universal design allows the system to adapt to different communication needs without requiring completely separate systems
3Adaptability or versatility
If legacy communication protocols are maintained for interoperability, then compatibility with existing systems is ensured, but data transfer rates remain slow
Solution Approach 1:
The communication architecture is segmented into two protocol layers: the wired connection implements modern high-speed communication protocols for fast data transfer, while the wireless in-band connection maintains legacy protocols for compatibility and power transfer control, allowing each layer to operate at its optimal performance level
