Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless power transmission is implemented without real-time monitoring, then power can be transmitted to devices, but power consumption efficiency cannot be optimized and shadow areas cannot be identified
Solution Approach 1:
The patent implements real-time feedback mechanisms where the wireless power transmitter continuously monitors power consumption data, charging efficiency metrics, and device status information. This feedback enables dynamic optimization of power transmission parameters and identification of shadow areas, resolving the contradiction by making the system self-regulating without requiring complex external management infrastructure.
Solution Approach 2:
The system performs self-monitoring and self-optimization of power transmission efficiency. The transmitter automatically collects statistical information about power consumption and charging efficiency, identifies shadow areas, and adjusts transmission parameters without external intervention, thereby improving productivity while maintaining acceptable system complexity.
2Area of stationary object
If multiple wireless power transmitters are deployed to cover larger areas, then power availability increases, but shadow areas with inadequate power transmission may still exist and become harder to identify
Solution Approach 1:
Each wireless power transmitter continuously monitors and reports power transmission effectiveness data to a central management system. This feedback mechanism enables the system to identify shadow areas where power transmission is inadequate, even in large-scale deployments with multiple transmitters, by aggregating and analyzing data from all transmitters to detect coverage gaps.
Solution Approach 2:
The management system performs multiple functions simultaneously: it monitors individual transmitter performance, identifies shadow areas, optimizes power distribution, and manages device connections. This multi-functional approach ensures reliable power transmission across large coverage areas by coordinating multiple transmitters effectively.
3Loss of energy
If real-time statistical information collection is implemented across all devices, then power consumption can be optimized, but data processing complexity and communication overhead increase
Solution Approach 1:
Each wireless power transmitter autonomously collects and processes statistical information about its own power consumption and charging efficiency. This self-service approach minimizes communication overhead by having devices report only essential aggregated data rather than raw continuous streams, optimizing power consumption while keeping data processing complexity manageable.
