Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging technology is implemented to eliminate cables and improve portability, then ease of operation and portability are improved, but device complexity increases due to the need for power transmission and reception components
Solution Approach 1:
The patent combines power transmission and reception capabilities within a single electronic device system. The transmitting device integrates power transmission components (coil, controller) while the receiving device integrates power reception components (coil, battery management), merging charging functionality into the devices themselves rather than requiring external charging equipment.
Solution Approach 2:
The wireless charging system is designed to be universally applicable to different electronic devices. The communication interface and power transmission protocol are standardized to enable charging across device types, making the wireless charging solution multi-functional and broadly compatible rather than device-specific.
2Productivity
If power-related information is obtained and analyzed to determine optimal charging parameters, then charging efficiency is improved, but loss of time increases due to the additional communication and processing steps required
Solution Approach 1:
The transmitting device obtains power-related information from the receiving device before initiating power transmission. This preliminary action includes querying battery status, capacity, and charging requirements, allowing the system to pre-determine optimal transmission parameters and avoid delays during the charging process.
Solution Approach 2:
The system implements continuous feedback through the communication interface between transmitting and receiving devices. The receiving device provides real-time battery status information, and the transmitting device adjusts power transmission parameters based on this feedback, optimizing charging efficiency while minimizing time loss through adaptive control.

AI summary
A method for sharing, at a first electronic device, wireless power with a second electronic device is provided. The method includes performing connection with the second electronic device; obtaining power-related information of the second electronic device; determining a power state of the second electronic device based on the power-related information of the second electronic device; determining an amount of electric power to be transmitted to the second electronic device based on the power state of the second electronic device; and transmitting the electric power of the determined amount to the second electronic device. Charging is enabled anytime, anywhere, as long as there is an electronic device to share electric power, thereby increasing user convenience.
