Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless power transmitting devices and receiving devices are manufactured according to different version standards, then each device can operate according to its own standardized technical specification, but compatibility between legacy version products and new version products deteriorates
Solution Approach 1:
The patent applies preliminary action by having the wireless power receiving device transmit version information (packet structure type) before the actual power transmission begins. This allows the transmitting device to identify the receiving device's version in advance and adjust its communication protocol accordingly, preventing compatibility issues during operation. The version identification occurs during the initial communication phase, enabling the system to adapt to different standards before power transfer starts.
Solution Approach 2:
The patent implements dynamics by making the communication protocol flexible and adaptive based on the detected version information. The transmitting device dynamically adjusts its packet structure and communication method according to whether the receiving device supports legacy or new version standards. This dynamic adaptation allows the system to switch between different protocol versions seamlessly, maintaining compatibility while supporting multiple standards.
2Adaptability or versatility
If version information is always transmitted by the wireless power receiving device, then compatibility information is always available, but communication overhead increases
Solution Approach 1:
The patent applies the taking out principle by extracting version information transmission to occur only when necessary - specifically, during the initial connection and authentication phase. The version information is embedded within existing communication packets rather than being transmitted as separate dedicated data. This extraction approach provides version information when needed while minimizing additional communication overhead by utilizing existing communication channels efficiently.
