Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high power levels are transmitted to all wireless power receivers, then sufficient power is provided for large receivers, but power is wasted when small receivers are charged
Solution Approach 1:
The wireless power transmitter dynamically adjusts the power transmission level based on the receiver class information obtained through communication. The system transitions from a static high-power transmission mode to a dynamic adaptive mode where power levels are modulated according to the specific receiver requirements, thereby eliminating energy waste while maintaining sufficient power delivery capability.
Solution Approach 2:
The system changes the power transmission parameter (power level) based on the receiver class. By categorizing receivers into different classes and adjusting the transmitted power parameter accordingly, the system optimizes energy efficiency while ensuring each receiver receives appropriate power levels for its size and requirements.
2Productivity
If a single power transmission unit is used, then device complexity is reduced, but charging efficiency is insufficient for different receiver types
Solution Approach 1:
The wireless power transmitter is segmented into multiple power transmission units, each capable of operating independently. This segmentation allows the system to selectively activate only the necessary number of units based on receiver requirements, improving charging efficiency for different receiver types while managing overall system complexity through modular architecture.
Solution Approach 2:
Multiple power transmission units are designed with universal functionality to handle different receiver classes. Rather than creating specialized transmitters for each receiver type, the system uses multi-functional units that can adapt their operation through communication-based classification, achieving high charging efficiency without proportionally increasing device complexity.
3Loss of energy
If communication protocols are implemented for receiver classification, then power transmission efficiency is improved, but system complexity increases
Solution Approach 1:
The communication protocol implements a feedback mechanism where receivers provide class information to the transmitter, and the transmitter adjusts power transmission accordingly. This feedback loop enables efficient energy transmission by matching supply to demand, with the added benefit of standardized communication protocols that manage system complexity through established interaction frameworks.
