Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless power delivery systems use multiple transmitters to improve power transmission capacity, then productivity increases, but system complexity increases and reliability decreases when transmitters are damaged
Solution Approach 1:
The system divides the transmitter array into independently controllable segments or groups. When damage occurs to one transmitter or group, only that segment is affected while other segments continue operating. This is achieved through independent control channels and modular architecture that allows selective activation/deactivation of transmitter elements without bringing down the entire system.
Solution Approach 2:
The system dynamically adjusts transmission parameters such as phase, amplitude, and frequency of individual transmitters to optimize power delivery. When transmitters are damaged, the system changes parameters of remaining functional transmitters to compensate for losses and maintain reliable power transmission. This includes real-time beamforming adjustments and power level modifications.
2Productivity
If wireless power delivery systems use multiple transmitters to scale power transmission, then productivity increases, but device complexity increases due to frequency synchronization requirements
Solution Approach 1:
The system employs feedback mechanisms where transmitters exchange frequency and phase information with control channels. Each transmitter receives feedback about the overall system state and adjusts its own frequency accordingly to maintain synchronization. This closed-loop control automatically handles frequency alignment without requiring complex manual coordination.
Solution Approach 2:
Transmitters are designed with autonomous frequency synchronization capabilities, where each transmitter independently adjusts its frequency based on local measurements and pre-established synchronization protocols. The system self-regulates frequency alignment through distributed control algorithms, reducing the need for centralized complex synchronization management.
