Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If transmission power is increased to compensate for low transmission efficiency in wireless energy charge, then energy charge efficiency is improved, but device complexity and operation management difficulty increase
Solution Approach 1:
The terminal dynamically adjusts its operation mode based on the overlap between energy charge and communication time resources. The control unit determines whether to prioritize energy charge reception or communication based on real-time resource allocation, enabling flexible adaptation to different operational scenarios and resolving the complexity of managing both functions simultaneously
Solution Approach 2:
The time resources are segmented into distinct energy charge time resources and communication time resources. By dividing the operational timeline into separate segments for each function, the system manages the complexity of coordinating wireless energy charge and communication operations through structured time division
2Productivity
If wireless energy charge and communications are performed simultaneously, then productivity is improved, but transmission efficiency decreases due to resource conflicts
Solution Approach 1:
The system employs periodic time-division multiplexing where energy charge and communication operations are allocated to alternating time periods. This periodic structure allows both functions to operate efficiently in sequence while maintaining overall system productivity, preventing resource conflicts that would reduce transmission efficiency
3Power
If higher transmission power is used for wireless energy charge, then energy charge rate is improved, but harmful factors increase due to radio wave interference
Solution Approach 1:
The harmful interference effect is extracted and managed by separating energy charge and communication into different time resources. By removing the simultaneous operation requirement, the system eliminates the interference problem while maintaining high power transmission for energy charge during dedicated time periods
