1Use of energy by moving object
If a transmitting device for wireless communication is used to transfer power, then power can be transmitted wirelessly over long distances, but circuit complexity increases and power efficiency decreases
Solution Approach 1:
The patent extracts and removes unnecessary communication-specific circuits from the transmitting device. By separating the power transmission function from data communication functions, the device eliminates complex modems, protocols, and processing units required for high-speed data transmission, retaining only the essential power amplification and modulation circuits needed for efficient wireless power transfer.
Solution Approach 2:
The patent uses a simplified transmitting device design that copies only the essential power transmission functionality from complex wireless communication devices. Instead of implementing full communication protocols and data processing chains, the invention creates a dedicated power transmission system that replicates the core electromagnetic transmission capability without the overhead of communication infrastructure.
2Speed
If complex circuits are used to transmit data streams at high speed, then data transmission capability is improved, but power efficiency decreases
Solution Approach 1:
The patent removes high-speed data transmission circuits including advanced modems, error correction encoders, and protocol processing units. By extracting these energy-intensive components, the device achieves high power efficiency while maintaining the capability to transmit power wirelessly, accepting that high-speed data communication is not the primary function.
Solution Approach 2:
The patent employs simpler, lower-cost circuit components that are adequate for power transmission but would be insufficient for high-speed data communication. These simplified circuits consume less power and are optimized for the specific task of wireless power transfer rather than general-purpose high-speed communication.
