Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a manager device is added to control transmitters for radio power transmission, then power transmission efficiency is improved, but system cost increases
Solution Approach 1:
The patent makes existing radio communication devices perform dual functions: they simultaneously handle communication signals and power transmission signals. The transmitter and receiver are configured to process both types of signals through the same hardware components, eliminating the need for separate dedicated power transmission control devices while maintaining transmission efficiency
Solution Approach 2:
The patent combines the communication signal processing path and power signal processing path into a unified system. The transmitter transmits both communication signals and power signals through the same antenna and amplifier, while the receiver processes both signal types through shared components, thereby reducing overall system complexity and cost
2Area of stationary object
If multiple transmitters are used for radio power transmission, then coverage area is improved, but system cost increases
Solution Approach 1:
Existing communication transmitters are configured to provide both communication service and power transmission service. By utilizing the same hardware infrastructure for dual purposes, the system expands coverage area without proportionally increasing the number of dedicated power transmission devices, thereby controlling system cost

AI summary
A radio power transmission system and a radio power transmission method are provided. The radio power transmission system includes a first radio device and a second radio device including a control signal generator and an antenna. The control signal generator generates a control signal for synchronizing frequencies and phases of power waves, based on signals indicating reception intensities of the power waves in a receiving device receiving the power waves. The antenna transmits the control signal to a plurality of the first radio devices. In the radio power transmission system, the plurality of first radio devices radiate, toward the receiving device, the power waves having the frequencies and phases set to a predetermined value based on the control signal.
