Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If microwave power transmission is used to transmit large capacity power from space to ground, then power transmission capability is improved, but transmission distance is limited to visible range only
Solution Approach 1:
The patent changes the fundamental parameter of electromagnetic wave frequency from microwave range to radio wave range. This parameter change enables the transmission distance to extend beyond visible range while maintaining power transmission capability, resolving the contradiction between power transmission capability and transmission distance.
2Reliability
If separate transmission/reception devices and base station construction are used for microwave power transmission, then power transmission reliability is improved, but device complexity increases
Solution Approach 1:
The patent makes mobile communication devices serve dual functions: both data communication and power reception. The existing mobile device infrastructure (antennas, processors, power management circuits) is utilized for power reception, eliminating the need for separate dedicated power transmission/reception devices and base stations, thus reducing device complexity while maintaining reliability.
3Reliability
If dedicated microwave power transmission system is constructed, then power transmission stability is improved, but adaptability decreases due to restriction to special use
Solution Approach 1:
The patent enables mobile devices to simultaneously perform data communication and power reception functions using the same radio wave infrastructure. This multi-functionality approach allows the system to adapt to various applications (mobile phones, tablets, laptops, wireless sensors) without requiring dedicated power transmission infrastructure, thereby improving adaptability while maintaining stability through established communication protocols.
4Weight of moving object
If battery charging is required for mobile devices, then portability is improved, but continuous power supply capability deteriorates
Solution Approach 1:
The patent implements continuous power supply to mobile devices through wireless power transmission via radio waves. Devices can receive power continuously while in use, eliminating the need for periodic battery charging. This maintains portability by removing or reducing battery requirements while providing uninterrupted power supply, resolving the contradiction between portability and continuous power capability.
