Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless power transmission is implemented using conventional methods, then power can be supplied to devices through fixed lines or direct charging, but the ability to relay power between devices without wired connection is limited
Solution Approach 1:
The electronic device is designed with dual functionality to both transmit and receive wireless power signals. The power transmission unit and power reception unit are integrated into the same device, enabling it to act as either a power source or a power recipient depending on operational needs. This multi-functionality allows the device to relay power between multiple devices without requiring separate dedicated charging devices for each function.
Solution Approach 2:
The electronic device serves as an intermediary in the power transmission chain by receiving power from a first apparatus and transmitting it to a second apparatus. This mediator role enables power relay functionality where the device bridges the gap between power source and power consumer, allowing indirect wireless power transfer without direct connection between the original power source and the target device.
2Adaptability or versatility
If devices are equipped with both power transmission and reception functions, then power relaying between devices is enabled, but communication resource usage becomes more complex
Solution Approach 1:
The controller receives power control messages from the second apparatus through the power conversion unit and uses this feedback to determine whether to activate the power transmission function. This feedback mechanism allows the device to dynamically adjust its power transmission status based on the actual power needs and communication resource availability, optimizing resource usage while managing the complexity of having dual power functions.
3Ease of operation
If wireless power transmission is used, then devices can operate without wired connections, but the range and reliability of power transfer are limited compared to wired connections
Solution Approach 1:
The controller determines whether to activate power reception or transmission functions in advance based on received power control messages and operational conditions. This preliminary determination allows the system to prepare and switch between modes proactively, ensuring reliable power transfer by establishing the optimal configuration before power transmission begins, thereby maintaining stability despite the wireless nature of the connection.
