Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless charging systems lack an efficient method for selecting the appropriate communication protocol between wireless power transmitters and receivers, leading to potential data transmission or reception issues due to unsupported protocols and protocol compatibility problems.
Innovation Solution
A method is introduced where the wireless power receiver transmits its supported communication protocols to the transmitter, and based on the received information, both devices decide on a suitable protocol for data transmission or reception, allowing for the selection of the best protocol from a list of supported options, including Zigbee, Bluetooth, and Near Field Communication, to ensure effective data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed communication protocol is used between wireless power transmitter and receiver, then the system structure is simple, but the adaptability to different communication standards is poor
Solution Approach 1:
The wireless power receiver pre-transmits its supported communication protocols to the transmitter before actual data communication. This preliminary action allows the transmitter to know which protocols the receiver supports, enabling automatic protocol selection without requiring complex real-time negotiation mechanisms.
Solution Approach 2:
The patent introduces an intermediary mechanism where the receiver's protocol information acts as a mediator between the transmitter and receiver. The transmitter uses this intermediate information to select an appropriate protocol from the list provided by the receiver, avoiding direct complex protocol compatibility checking between both devices.
2Adaptability or versatility
If multiple communication protocols are supported, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The patent segments the protocol support capability into two parts: the receiver maintains a list of supported protocols, and the transmitter selects from this list. This segmentation allows multiple protocols to be supported without requiring both devices to implement all protocols, reducing overall system complexity while maintaining versatility.
Solution Approach 2:
The patent implements dynamic protocol selection where the communication protocol is not fixed but can be changed based on the receiver's supported protocols. The system dynamically adapts the communication protocol according to the specific receiver's capabilities, allowing flexibility without requiring static support for all possible protocols in both devices.
3Reliability
If protocol information is exchanged before communication, then communication reliability improves, but the initialization time increases
Solution Approach 1:
The patent performs protocol information exchange as a preliminary action before actual data communication. The receiver transmits its supported protocols in advance, allowing the transmitter to select an appropriate protocol before data transmission begins. This ensures communication reliability by establishing protocol compatibility upfront while minimizing time loss by using a simple list-based approach rather than iterative negotiation.

AI summary
This specification provides a method for deciding a communication protocol between a wireless power transmitter and a wireless power receiver. To this end, a method for deciding a communication protocol by the wireless power receiver for data transmission or reception with the wireless power transmitter includes transmitting first communication protocol information indicating communication protocols supportable by the wireless power receiver itself to the wireless power transmitter, and deciding a communication protocol for the data transmission or data reception based on second communication protocol information, which indicates communication protocols selected based on the first communication protocol information, when the second communication protocol information is received from the wireless power transmitter.
