Solution Overview
Problem
Current wireless power transfer systems require different apparatuses for in-band and out-band communication methods, leading to decreased convenience due to the need for specific power transmission apparatuses based on communication methods used.
Innovation Solution
A power transmission apparatus with both in-band and out-band communication capabilities, where a deciding unit determines the appropriate communication method based on device information from the power reception apparatus, allowing for flexible communication method selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a power transmission apparatus uses only one communication method (in-band or out-band), then the device complexity is reduced, but the adaptability to different power reception apparatuses decreases
Solution Approach 1:
The power transmission apparatus is designed with both in-band communication unit and out-band communication unit, enabling it to perform multiple communication functions. This multi-functionality allows the apparatus to adapt to different power reception apparatuses that support different communication methods, resolving the contradiction between adaptability and device complexity by making the transmitter universal rather than requiring multiple specialized devices.
Solution Approach 2:
The power transmission apparatus dynamically selects between in-band and out-band communication methods based on the capabilities of the power reception apparatus. The deciding unit determines which communication method to use, allowing the system to adapt its behavior in real-time rather than being fixed to one method, thus achieving versatility without requiring parallel dedicated hardware for each method.
2Ease of operation
If different power transmission apparatuses are used for different communication methods, then the communication reliability is optimized for each method, but the ease of operation decreases
Solution Approach 1:
The patent combines both in-band and out-band communication units within a single power transmission apparatus. This merging allows the user to operate one unified device that can handle multiple communication methods, improving ease of operation while maintaining the reliability benefits of both communication approaches through the deciding unit's selection capability.
Solution Approach 2:
The deciding unit receives feedback about the power reception apparatus's communication capabilities and automatically selects the appropriate communication method. This feedback mechanism ensures that the most reliable communication method is chosen based on the specific receiver's capabilities, maintaining communication reliability while simplifying user operation to a single unified interface.

AI summary
A power transmission apparatus has a first communication function for communicating with a power reception apparatus and a second communication function for communicating with the power reception apparatus at a radio frequency different from a radio frequency used in the first communication function, and makes a decision as to whether to use the first communication function or the second communication function in communication for controlling wireless transmission of power, the decision being made on the basis of device information obtained from the power reception apparatus through communication using the first communication function.
