Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manual connection and disconnection of external electronic devices is performed to check battery power, then battery charge state information can be obtained, but usability and convenience are reduced
Solution Approach 1:
The wireless charger automatically detects and provides battery charge state information of external electronic devices without requiring manual connection or user intervention. The system performs self-service by autonomously acquiring device information, checking battery states, and presenting charging guidance through the electronic device's interface.
Solution Approach 2:
The electronic device acts as an intermediary between the wireless charger and the user. It receives battery charge state information from the wireless charger and presents it through a charging guide interface, eliminating the need for direct manual connection between the user and external electronic devices.
2Loss of information
If external electronic devices are connected to check battery power, then charging information can be obtained, but the system complexity and operation steps increase
Solution Approach 1:
The patent extracts the battery charge state information acquisition function from the electronic device and places it in the wireless charger. The wireless charger now directly communicates with external electronic devices to obtain charging information, simplifying the overall system architecture by removing unnecessary connection steps.
3Loss of information
If individual checking of each external electronic device is performed, then accurate battery information is obtained, but time consumption increases
Solution Approach 1:
The wireless charger merges the detection and information acquisition processes for multiple external electronic devices into a single unified operation. It simultaneously detects all connected devices and retrieves their battery charge state information in one action, eliminating the need for sequential individual checking.

Magnetic coupling or resonant coupling may be formed between a source resonator of the wireless charger and a target resonator of the electronic device
Data Source
AI summary
A method of providing a wireless charging guide and/or an electronic device for performing the same are provided. The electronic device includes a display and at least one processor configured to determine whether the electronic device is in a charging area of a wireless charger, based on a determination that the electronic device is in the charging area, identify at least one external electronic device that is currently connected to the electronic device and/or has a record of being previously connected to the electronic device, acquire battery charge state information of the identified at least one external electronic device, and control the display to output a charging guide interface for the identified at least one external electronic device, based on a charge available state of the wireless charger and the acquired battery charge state information.
