Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a conventional wireless power connector system uses a closed magnetic loop configuration between transmitting and receiving connectors, then power transmission efficiency is improved, but the system loses flexibility and cannot support multiple receiving connectors
Solution Approach 1:
The magnetic core is segmented into multiple independent sections, each capable of forming a closed magnetic loop with a respective receiving connector. This allows the transmitting connector to maintain efficient power transmission to multiple receiving connectors simultaneously, rather than requiring a single unified magnetic loop.
Solution Approach 2:
The transmitting connector is designed with a universal magnetic core structure that can simultaneously serve multiple receiving connectors. Each receiving connector can independently form a closed magnetic loop with the transmitting connector, enabling the system to adapt to different configurations while maintaining high transmission efficiency.
2Loss of energy
If a wireless power connector system is designed for high efficiency through close magnetic coupling, then power transmission efficiency is improved, but the system requires a 1:1 relationship between transmitting and receiving connectors
Solution Approach 1:
The magnetic coupling is segmented into multiple independent coupling paths, each maintaining the close magnetic coupling required for high efficiency. This segmentation allows one transmitting connector to couple with multiple receiving connectors without compromising the efficiency of individual coupling paths.
Solution Approach 2:
The system transitions from a single-dimension 1:1 connector relationship to a multi-dimensional configuration where one transmitting connector can simultaneously engage with multiple receiving connectors. This is achieved through the spatial arrangement of multiple magnetic core sections that can each independently form closed loops.

AI summary
The invention relates to a wireless power connector and a wireless power connector system including at least one wireless power connector for contactlessly receiving electric power from a second connector and for contactlessly supplying electric power to a third connector. In order to enable the wireless power connector to inductively forward electric power received from the second connector, the invention suggests providing a first and a second mating end respectively connectable to the second and the third connector and a magnetic core extending between the first and the second mating end. A coil is wound around the magnetic core and configured to output, as an alternating current, at least parts of the electric power received from the second connector. The magnetic core interconnects the first and the second mating end such that, in a connected state, the magnetic core inductively forwards electric power to the third connector.
