Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless energy transmission is performed on multiple receiving devices in a sharing manner, then the system can charge multiple devices simultaneously, but the ability to prioritize specific devices for urgent charging needs is lost
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different receiving devices based on their specific charging needs. The sending device identifies preferential receiving devices and allocates energy transmission resources differently for each device according to its priority level, allowing simultaneous charging with differentiated service quality.
Solution Approach 2:
The patent implements dynamics by enabling the sending device to dynamically adjust energy transmission parameters (such as power allocation, beamforming weights) based on real-time identification of preferential devices and their remaining energy levels. This allows the system to adapt charging priorities dynamically during the charging process.
2Reliability
If the system charges all devices equally in a sharing manner, then fairness is maintained, but devices with urgent charging needs cannot receive preferential treatment
Solution Approach 1:
The patent applies preliminary action by having the sending device perform preliminary identification and classification of receiving devices into preferential and non-preferential categories before initiating energy transmission. This preliminary sorting allows the system to establish priority-based charging strategies in advance, ensuring urgent devices receive timely attention.
Solution Approach 2:
The patent implements feedback mechanisms where receiving devices transmit information about their charging status and energy needs to the sending device. The sending device uses this feedback to continuously adjust energy allocation, ensuring that preferential devices receive adequate power while maintaining overall system fairness.
3Productivity
If phase calibration is performed for optimal energy transmission, then transmission efficiency is maximized, but the system cannot adapt to changing priority needs of different devices
Solution Approach 1:
The patent applies dynamics by making the phase calibration process adaptive rather than static. The sending device performs phase calibration specifically for preferential receiving devices and can re-calibrate when priority conditions change. This dynamic approach maintains high transmission efficiency while adapting to changing charging priorities.
Solution Approach 2:
The patent segments the phase calibration process by applying it selectively to different groups of receiving devices based on their priority levels. Rather than uniform calibration for all devices, the system performs targeted calibration for preferential devices, optimizing efficiency for high-priority transmissions while reducing overhead for others.
