Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a rechargeable power source system is integrated into a water vessel, then operational range and sustainability are improved, but device complexity and integration requirements increase
Solution Approach 1:
The power source system is divided into modular components including battery packs, container systems, and interchangeable modules that can be independently managed and replaced, reducing overall system complexity while maintaining extended operational capability
Solution Approach 2:
The power source system is designed with universal interfaces and standardized configurations that can serve multiple functions including propulsion, auxiliary power, and energy storage, thereby extending operational range without proportionally increasing complexity
2Ease of operation
If battery packs are placed on the deck of marine vehicles, then accessibility and ease of replacement are improved, but deck space is reduced
Solution Approach 1:
Instead of placing battery packs only on the horizontal deck surface, the system utilizes vertical stacking arrangements and integrates batteries into the hull structure or dedicated compartments, thereby maintaining accessibility while preserving deck space for other uses
3Quantity of substance
If an autonomous barge is used for supplementing energy storage, then power source capacity is improved, but system complexity and coordination requirements increase
Solution Approach 1:
A standardized power transfer interface and control protocol acts as an intermediary between the autonomous barge and the main vessel, enabling seamless energy transfer while simplifying the coordination complexity through established communication standards
4Productivity
If payment terminals and swapping systems are integrated, then operational efficiency and convenience are improved, but device complexity increases
Solution Approach 1:
The payment terminal, swapping mechanism, and power transfer interface are merged into an integrated unit that performs multiple functions simultaneously, thereby improving operational efficiency while managing complexity through functional integration rather than separate components

AI summary
The invention relates to a marine rechargeable power source system (MPS) for water vessels at least partially electrically driven comprising a rechargeable power source, a source management system and a container which may be buoyant or nonbuoyant. The MPS may further comprise power transfer interfaces, power cables, thermal management systems, power sources, payment terminals, mobility devices. The MPS may provide data transmissions, may be a swappable power source and its container may be conveniently shaped. The MPS may be provided in a cloud-based communication system, a hydrogen gas powering system, a marine fuelling system and a modular system. An offshore swapping method using the MPS is proposed which can comprise a step of transferring power between the MPS and the water vessel at least partially electrically driven while stationary or in a motion. A swapping place may comprise charging apparatuses and power sources.
