Solution Overview
Problem
Conventional radio power supply systems face challenges in selecting an optimal frequency for radio power supply, leading to interference with existing radio communication systems, as they typically use specific microwave frequencies without a method to determine the most suitable frequency for power supply.
Innovation Solution
A radio power supply system that includes a power-fed terminal and a microwave transmission terminal, where the terminal receives and measures energy across multiple frequency candidates, selects an optimum frequency for maximum energy conversion, and communicates this frequency for efficient power supply, minimizing interference with other communication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a specific microwave frequency is used for radio power supply, then power supply can be performed, but interference with radio communication systems occurs
Solution Approach 1:
The patent changes the frequency parameter of the microwave used for power supply. Instead of using a fixed frequency, the system transmits power supply requests containing frequency information and receives responses with available frequency candidates, then selects an optimal frequency from multiple options to avoid interference with communication systems.
Solution Approach 2:
The system dynamically adjusts the microwave frequency based on real-time availability information from communication systems. The power-fed terminal and microwave transmission terminal engage in a negotiation process where frequency information is exchanged and updated, allowing the system to adapt to changing spectral conditions.
2Object-affected harmful factors
If multiple frequency candidates are available, then interference with radio communication can be reduced, but a method for selecting the optimum frequency for power supply is needed
Solution Approach 1:
The patent implements a feedback mechanism where the power-fed terminal sends a power supply request with frequency information, the microwave transmission terminal responds with available frequency candidates, and the power-fed terminal selects and confirms the optimal frequency. This closed-loop feedback process enables intelligent frequency selection without excessive complexity.
