Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single charging station type is provided onboard, then the device complexity is reduced, but the adaptability to different electric vehicle types is insufficient
Solution Approach 1:
The water vessel is equipped with multiple charging station types including AC charging stations, DC charging stations, and wireless charging stations, allowing a single vessel to serve multiple electric vehicle types with different charging requirements, thereby achieving universal charging compatibility without requiring separate specialized vessels
2Adaptability or versatility
If fixed charging interfaces are used, then the ease of manufacture is improved, but the adaptability to different vehicle sizes and charging needs is reduced
Solution Approach 1:
The charging interfaces are designed to be adjustable and mobile rather than fixed, allowing the interfaces to be repositioned and reconfigured according to different vehicle sizes and charging requirements, providing dynamic adaptability while maintaining manufacturing feasibility through standardized interface components
3Loss of energy
If traditional power generation systems are used, then the reliability of power supply is ensured, but the environmental impact and energy efficiency are insufficient
Solution Approach 1:
The water vessel integrates multiple power generation sources including solar panels, wind turbines, and regenerative braking systems into a hybrid power system, combining renewable energy sources with traditional power generation to maintain supply reliability while significantly improving energy efficiency and reducing environmental impact
4Productivity
If conventional charging systems are used, then the ease of operation is maintained, but the productivity of charging operations is insufficient
Solution Approach 1:
The system incorporates wireless charging stations that replace traditional mechanical plug-and-play charging interfaces, enabling contactless power transfer and significantly improving charging speed and convenience while reducing mechanical wear and operational complexity through automated coupling mechanisms

AI summary
The invention relates to a marine charging system for an electric vehicle (MCS) comprising a water vessel providing one or more wired/wireless charging stations to charge/discharge the electric vehicle. The system may provide data transmissions and may be provided in cloud/fog/edge computing systems. The water vessel may be powered by various propulsion systems. It may provide power generators, use regenerative power, swap, provide rechargeable power sources/swappable rechargeable power sources and a thermal management system. The charging stations may provide charging interfaces and both may be provided at about defined naval constructions, be adjustable, mobile. The MCS may be provided in an electric vehicle charging system comprising coupled electric vehicles and in an offshore charging system comprising a coupled marine power source to provide power while the vessel be stationary or in a motion. The MCS may be provided in a modular system. Marine charging and swapping methods are proposed.
