Solution Overview
Problem
Current wireless power transfer technologies, particularly those following the WPC standard, face limitations in communication methods, as they are vulnerable to electrical and magnetic disturbances, provide only one-way communication, and have slow transmission speeds, making them unsuitable for applications requiring bidirectional information transfer and high data exchange.
Innovation Solution
A method that allows wireless power transmitters and receivers to dynamically select between different communication modes, including those beyond the standard WPC communication method, by determining the availability of alternative modes and initializing the communication status accordingly, enabling bidirectional communication and supporting various communication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the WPC standard communication method is used, then wireless power transfer compatibility is ensured, but communication reliability deteriorates due to vulnerability to electrical and magnetic disturbances
Solution Approach 1:
The patent introduces an intermediary communication channel that operates independently from the power transfer channel. This intermediary channel uses a separate communication protocol that is not susceptible to electrical and magnetic disturbances affecting the power transfer, thereby ensuring reliable bidirectional communication while maintaining compatibility with the WPC standard power transfer mechanism.
Solution Approach 2:
The communication system is segmented into two independent channels: one for power transfer control (maintaining WPC standard compatibility) and another for data exchange (ensuring reliability against disturbances). This segmentation allows each channel to be optimized for its specific function without interference from the other.
2Ease of operation
If the WPC standard communication method is used, then power transfer control is achieved, but information transfer capability deteriorates due to one-way communication limitation
Solution Approach 1:
The patent merges two communication approaches: the WPC standard one-way control channel and a supplementary bidirectional data channel. The control channel maintains ease of operation for power transfer, while the supplementary channel enables bidirectional information exchange, allowing the system to support both functions simultaneously.
3Ease of operation
If the WPC standard communication method is used, then power transfer is controlled, but data transfer speed deteriorates due to slow transmission speed
Solution Approach 1:
The communication system is divided into two segments: the WPC standard channel for power transfer control (maintaining ease of operation) and a high-speed data channel for information exchange (providing fast transmission speed). This segmentation allows each channel to be optimized for its primary function without compromise.
