Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless power transmitting device transmits power to multiple candidate receiving devices, then power delivery capability is improved, but device complexity and authorization management difficulty increase
Solution Approach 1:
The system performs preliminary authorization checks and device identification before initiating power transmission. The transmitting device identifies candidate receiving devices and establishes authorization status in advance, so when multiple devices are present, the authorization management is already completed and does not add complexity to the power delivery process
Solution Approach 2:
The system segments the power delivery process into distinct phases: device identification phase, authorization determination phase, and power transmission phase. This segmentation allows complex multi-device scenarios to be handled through a structured sequence of simpler operations, reducing overall system complexity
2Ease of operation
If wireless power receiving device establishes communication link with audiovisual electronic device, then user interface control capability is improved, but loss of time for establishing connection increases
Solution Approach 1:
The communication link establishment and device pairing are performed preliminarily before power transmission begins. The transmitting device and receiving device exchange identification information and establish communication protocols in advance, so that when power delivery is needed, the connection is already established and no additional time is required
Solution Approach 2:
The patent merges the device identification, authorization, and communication link establishment processes into a single integrated procedure. By combining these steps that were previously separate, the system reduces the total time required while maintaining full user interface control capability

AI summary
A wireless power system may include a wireless power transmitting device and a wireless power receiving device. The wireless power transmitting device may have a wired connection to an audiovisual electronic device. When the wireless power receiving device is attached to the wireless power transmitting device, the audiovisual electronic device may enter a paired mode with the wireless power receiving device. In the paired mode, the wireless power receiving device may control a user interface of the audiovisual electronic device. If the wireless power receiving device is not yet authorized for a paired mode with the audiovisual electronic device, a request for authorization may be displayed for the user in response to the wireless power receiving device being attached to the wireless power transmitting device.
