Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging is used to charge mobile devices, then charging convenience is improved, but power transmission capacity is insufficient
Solution Approach 1:
The patent combines multiple wireless charging devices into a collaborative charging network where devices can share and aggregate their power transmission capabilities. By merging the charging capacities of multiple devices, the system achieves sufficient power transmission while maintaining wireless charging convenience.
Solution Approach 2:
Mobile devices are designed to serve dual functions: as power consumers during normal operation and as power transmitters during collaborative charging. This multi-functionality allows any device in the network to contribute its charging capacity, effectively increasing the total power transmission capacity available to the group.
2Productivity
If multiple devices charge simultaneously using wireless charging, then charging parallelism is improved, but power supply capacity is insufficient
Solution Approach 1:
The patent segments the power supply task by assigning different roles to different devices in the network. Some devices act as primary chargers while others serve as secondary chargers or power relays. This segmentation allows multiple devices to charge simultaneously by drawing from different power sources within the network, effectively increasing total power supply capacity.
Solution Approach 2:
The system introduces a power management intermediary that coordinates power distribution among multiple charging devices. This intermediary optimizes the allocation of power resources, ensuring that multiple devices can charge simultaneously while preventing power conflicts and maximizing the utilization of available power capacity in the network.
3Adaptability or versatility
If power is transmitted wirelessly from one device to another, then charging flexibility is improved, but power loss increases
Solution Approach 1:
The system performs preliminary power aggregation by collecting excess power from multiple devices before transmission to the target device. By pre-assembling the required power quantity from multiple sources, the system reduces the total transmission distance and number of wireless power transfer operations needed, thereby minimizing cumulative power losses while maintaining charging flexibility.
