Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional communication circuits (infrared or Bluetooth) are added for bidirectional communication, then signal transmission capability is improved, but device complexity and number of parts increase
Solution Approach 1:
The wireless power supply system is designed to perform both power transmission and bidirectional communication functions using a single integrated system. The power supply circuit serves dual purposes: delivering electrical power and transmitting control signals, thereby eliminating the need for separate communication circuits and reducing overall system complexity.
Solution Approach 2:
The communication function is merged with the power supply function by superimposing communication signals onto the power supply waveform. This combination allows bidirectional communication to occur through the existing power transmission infrastructure without requiring additional dedicated communication hardware.
2Device complexity
If communication signals are superimposed on power supply waveform, then additional parts are eliminated, but noise generation and stable operation become problematic
Solution Approach 1:
The system performs preliminary actions by establishing a feedback mechanism that monitors power consumption levels before initiating signal transmission. This allows the system to adjust transmission parameters in advance, ensuring stable operation and minimizing noise interference by operating within optimal power ranges.
Solution Approach 2:
A feedback control mechanism is implemented where the power receiving side transmits power consumption information back to the power transmission side. This feedback loop enables dynamic adjustment of transmission parameters, ensuring stable operation and reducing noise by maintaining optimal operating conditions throughout power transfer.
3Device complexity
If unidirectional communication is used without feedback mechanism, then system simplicity is maintained, but power consumption increases due to continuous high power transmission
Solution Approach 1:
The system implements feedback by enabling the power receiving side to transmit power consumption information back to the power transmission side through the wireless power supply link. This feedback mechanism allows the transmission side to adjust power levels dynamically, reducing unnecessary power consumption while maintaining system simplicity without adding complex communication hardware.
Solution Approach 2:
The power transmission system transitions from static continuous high-power transmission to dynamic adaptive transmission. By receiving feedback on actual power consumption, the system can dynamically adjust transmission parameters to match actual needs, thereby reducing overall power consumption while maintaining operational simplicity.
