Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a power transmitting apparatus uses a first wireless power transmission method with a lower power limit (5W) to ensure compatibility with power receiving apparatuses that only support this method, then compatibility is improved, but the maximum transmission power is limited and cannot charge devices requiring higher power
Solution Approach 1:
The power transmitting apparatus is designed to support multiple wireless power transmission methods (first and second methods) simultaneously, making it universally compatible with different types of power receiving apparatuses. By incorporating both transmission methods, the system can adapt to devices that only support the first method while also being capable of high-power transmission using the second method when needed.
Solution Approach 2:
The system dynamically selects between the first and second wireless power transmission methods based on the capabilities of the connected power receiving apparatus. The selection is not fixed but changes according to the detected device type, allowing the system to optimize between compatibility and power transmission capability in real-time.
2Productivity
If the power transmitting apparatus transmits power using the first wireless power transmission method to a power receiving apparatus placed first on the charging stand, then the first device is charged, but devices supporting only the first method cannot be charged when the second method is used for other devices
Solution Approach 1:
The power transmitting apparatus includes detection means that identifies the type of power receiving apparatus connected and provides feedback to the determination means. This feedback mechanism enables the system to make informed decisions about which transmission method to use, ensuring that the selected method is compatible with the connected device while optimizing charging efficiency.
Solution Approach 2:
The system performs preliminary detection of the power receiving apparatus type before initiating power transmission. By detecting the device capabilities in advance and determining the appropriate transmission method beforehand, the system avoids compatibility issues during the charging process and ensures efficient power transfer from the start.

AI summary
A power transmitting apparatus transmits power by a first wireless power transmission method, transmits power by a second wireless power transmission method, detects a wireless power transmission method supported by a power receiving apparatus, and determines whether power is transmitted to a first power receiving apparatus by the first power transmission method or the second power transmission method, based on a detected wireless power transmission method supported by the first power receiving apparatus and a detected wireless power transmission method supported by a second power receiving apparatus.
