Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If wireless power transmission is performed without additional detection signals, then energy efficiency is improved and device complexity is reduced, but the ability to detect objects in the transmission region deteriorates
Solution Approach 1:
The wireless power transmission system performs both power transmission and object detection using the same transmitted radiation signals. The system analyzes scattering signals returned from objects in the transmission region, allowing a single transmission system to fulfill multiple functions without requiring separate detection hardware or additional probe signals.
Solution Approach 2:
The system uses its own transmitted power signals to perform detection functions. By analyzing how the transmitted radiation scatters off objects in the transmission region, the system serves its own detection needs without external assistance or additional dedicated detection resources.
2Measurement precision
If scattering signals are analyzed to detect objects, then object detection precision is improved, but device complexity increases due to additional detectors and processing modules
Solution Approach 1:
The same transmission infrastructure is used for both power transmission and detection functions. The system incorporates detectors and processing modules that analyze scattering signals from the transmitted radiation, allowing the system to maintain high detection precision while avoiding the need for completely separate detection systems.
Solution Approach 2:
The scattering signals act as intermediaries that carry information about objects in the transmission region. By analyzing these naturally occurring scattering signals rather than requiring direct interaction with objects, the system achieves accurate detection without complex direct measurement mechanisms.
3Reliability
If adaptive power control is implemented based on detected objects, then safety is improved, but response time increases due to signal analysis processing
Solution Approach 1:
The system continuously monitors scattering signals from objects in the transmission region and uses this information to dynamically adjust power transmission levels. This feedback mechanism enables real-time safety control by comparing detected object positions against safety thresholds and immediately modifying transmission parameters when necessary.
Solution Approach 2:
The system performs continuous background scanning and object detection before initiating high-power transmission. By预先 identifying objects and establishing baseline safety conditions, the system can maintain faster response times during actual power transmission operations while still ensuring safety through pre-established detection capabilities.
