Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If wireless power feeding is performed using a single transmitter with wireless LAN signals, then the system is simple and safe, but the transmission power is limited and charging efficiency is low
Solution Approach 1:
The patent divides the power transmission system into multiple independent transmitters (first transmitter, second transmitter, etc.) that can operate simultaneously. Each transmitter has its own transmission unit and control unit, allowing the system to achieve higher total transmission power while maintaining individual unit simplicity. The control unit coordinates multiple transmitters to work together without requiring complex reconfiguration of each transmitter.
2Productivity
If multiple transmitters are used to increase power, then transmission efficiency improves, but the control complexity increases
Solution Approach 1:
The patent combines multiple transmitters under a single control unit that manages power transmission coordination. The control unit receives power transmission requests, determines total required power, and allocates transmission tasks to appropriate transmitters. This centralized control approach simplifies management compared to having independent control for each transmitter, while enabling faster charging through parallel power delivery.
Solution Approach 2:
The control unit is designed to handle multiple functions: receiving power transmission requests from terminals, calculating required power levels, selecting which transmitters to activate, and coordinating simultaneous transmission. This multi-functional design reduces the need for separate specialized components for each function, maintaining system simplicity while achieving high productivity.
3Loss of time
If a single transmitter operates at maximum power, then charging time is reduced, but transmission efficiency decreases due to power limitations
Solution Approach 1:
The patent enables continuous power transmission by coordinating multiple transmitters to operate simultaneously or in coordinated sequence. Instead of a single transmitter operating intermittently at maximum capacity, multiple transmitters provide sustained power delivery, reducing charging time while maintaining efficient energy utilization through optimized power distribution across the terminal.
