Wireless Power Transmitter Remote Charging Status Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of an efficient method for users to check the charging status of devices or batteries using wireless power chargers, as existing technologies do not provide a reliable way to obtain charging information remotely.
Innovation Solution
A wireless power transmitter system that includes a power transmitting module, a communication module, and a processing module, which allows for the transmission of charging information to a remote mobile device upon request, using communication interfaces like Bluetooth Low Energy or Load Modulation, enabling users to monitor the charging status of wireless power receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless power charging is implemented without remote monitoring capability, then power transmission function is achieved, but user convenience and charging status tracking are deteriorated
Solution Approach 1:
The patent implements a feedback mechanism where the wireless power transmitter sends charging status information (battery level, charging state, temperature) to the remote mobile device. This allows users to monitor charging progress remotely, resolving the information loss problem while maintaining ease of operation through automatic status reporting
Solution Approach 2:
The patent introduces a communication module as an intermediary between the wireless power transmitter and the remote mobile device. This intermediary enables bidirectional communication, allowing the transmitter to send charging status information and the mobile device to send control commands, thereby solving the problem of remote monitoring without complicating the user interface
2Ease of operation
If charging information is always transmitted to remote device, then user convenience is improved, but energy consumption and communication overhead increase
Solution Approach 1:
The patent implements periodic transmission of charging status information at predetermined time intervals rather than continuous transmission. The processing module determines whether to transmit information based on whether a preset time interval has elapsed since the last transmission, reducing energy consumption while maintaining adequate monitoring capability
Solution Approach 2:
The patent establishes a communication connection between the wireless power transmitter and the remote mobile device before the charging process begins. This preliminary connection setup allows for efficient subsequent communication and enables the system to respond quickly to user requests without repeated connection handshakes, reducing overall communication overhead

AI summary
A wireless power transmitter that includes a power transmitting module, a communication module and a processing module is provided. The power transmitting module provides a wireless power to a wireless power receiver. The processing module receives a first request message from a remote mobile device through the communication module to request charging information of the wireless power receiver, determines whether the charging information is available, transmits available information to the remote mobile device under a condition that at least first part of the charging information is available, receives provided information from the wireless power receiver through the communication module under a condition that at least second part of the charging information is not available, and transmits the provided information through the communication module to the remote mobile device.
