Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple separate energy transfer systems are used to charge multiple mobile devices, then each device can be charged independently, but the device complexity and setup time increase significantly
Solution Approach 1:
The patent combines multiple transmitting units into a single modular energy transfer system where multiple transmitting units can be connected in series to form an extended energy transfer area. This allows multiple mobile devices to be charged simultaneously through one integrated system rather than requiring separate charging systems for each device, thereby reducing overall system complexity while maintaining high charging capacity.
Solution Approach 2:
The system is divided into modular transmitting units that can be independently configured and then connected in series. Each transmitting unit can be optimized for specific charging requirements, and the modular design allows flexible arrangement to match the number and positioning of mobile devices, reducing setup complexity while maintaining productivity.
2Reliability
If mobile devices are placed at predefined positions with high accuracy, then energy transfer efficiency is maximized, but the ease of operation decreases
Solution Approach 1:
The patent implements dynamic adjustment mechanisms that automatically adapt the energy transfer parameters based on the actual positioning of mobile devices. The system can dynamically adjust transmitting coil activation, power distribution, and synchronization to maintain optimal energy transfer efficiency even when devices are not precisely positioned, thereby improving ease of operation without sacrificing reliability.
Solution Approach 2:
The system incorporates feedback mechanisms that detect the position and status of mobile devices and automatically adjust the energy transfer parameters accordingly. This feedback loop ensures that the system maintains high energy transfer efficiency by adapting to actual device positions rather than requiring precise pre-positioning, making the system easier to operate.
3Productivity
If multiple transmitting units operate simultaneously without synchronization, then energy transfer capacity increases, but harmful interference increases
Solution Approach 1:
The patent implements synchronization communication between transmitting units that uses feedback mechanisms to coordinate their operation. Each transmitting unit receives synchronization signals from others and adjusts its transmitting phase and power level accordingly, allowing multiple units to operate simultaneously at high capacity while minimizing radiated interference through coordinated phasing and power management.
Solution Approach 2:
The system employs periodic synchronization cycles where transmitting units exchange status information and coordinate their operation in synchronized phases. This periodic coordination allows multiple units to maintain high overall energy transfer capacity while reducing interference through structured, phased operation rather than random simultaneous transmission.
