Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If power transmission is performed without prior parameter optimization, then power transmission can be initiated quickly, but power transmission loss increases significantly
Solution Approach 1:
The patent performs a calibration process before actual power transmission to determine optimal transmission parameters. This preliminary action includes calculating power transmission efficiency for multiple parameters, identifying the most efficient parameter, and setting it as the transmission parameter. By performing this optimization beforehand, the system achieves high efficiency power transmission without excessive loss.
2Loss of energy
If power transmission is performed without parameter optimization, then the transmission process is simple and quick, but unauthorized devices can receive power and efficiency decreases
Solution Approach 1:
The patent applies local quality by optimizing power transmission parameters specifically for the target device based on its position and characteristics. The system calculates power transmission efficiency for different parameters and selects the optimal one for the specific transmission scenario. This ensures that power is delivered efficiently and reliably to the intended target device while preventing unauthorized reception by other devices.
3Productivity
If multiple parameters are tested for optimization, then power transmission efficiency is maximized, but the calibration time and process complexity increase
Solution Approach 1:
The patent performs calibration by testing multiple power transmission parameters to identify the most efficient one. While this involves multiple tests, the system systematically evaluates parameters and selects the optimal one, balancing the need for high efficiency with acceptable calibration time. The calibration process determines the best parameter without requiring exhaustive testing of all possible parameters.

AI summary
A power transmission device includes a communication unit that transmits a power capability information transmission request via a communication channel and receives power capability information in response to the power capability information transmission request. The power transmission device also includes a processing unit that sets a parameter based on the power capability information. Further, the power transmission device includes a power transmission unit that wirelessly transmits power using the parameter. The communication unit transmits the power capability information transmission request before the power transmission unit wirelessly transmits the power.
