Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual navigation and delivery methods are used in marine vessels, then operational flexibility and human control are maintained, but automation capability and delivery efficiency are insufficient
Solution Approach 1:
The unmanned delivery system is divided into distinct functional modules: acquisition unit for destination information, automatic navigation unit for path planning and vessel control, and controller for coordination. This segmentation allows each module to be optimized independently while working together to achieve automated delivery, resolving the contradiction between automation and complexity.
Solution Approach 2:
The automatic navigation unit serves multiple functions including path planning, collision avoidance, and coordination with the controller, making it a multi-functional component that reduces overall system complexity while maintaining high automation capability.
2Productivity
If automated navigation systems are implemented in marine vessels, then delivery efficiency and accuracy are improved, but system complexity and implementation difficulty increase
Solution Approach 1:
By segmenting the automated delivery system into specialized units (acquisition unit, automatic navigation unit, controller), each with focused functionality, the system achieves high delivery efficiency through coordinated specialization while managing complexity through modular architecture.
Solution Approach 2:
The automatic navigation unit receives destination information from the acquisition unit and executes navigation while the controller coordinates their operations, creating a feedback loop that optimizes delivery efficiency while managing system complexity through structured information flow.
3Loss of time
If manual cargo handling procedures are used, then system simplicity is maintained, but delivery time and operational efficiency are insufficient
Solution Approach 1:
The system separates cargo delivery operations into distinct automated phases: destination acquisition, navigation to destination port, and controlled arrival. This segmentation enables unmanned operation that reduces delivery time while managing automation complexity through structured process division.
Solution Approach 2:
The acquisition unit obtains destination information in advance, allowing the automatic navigation unit to plan and execute the navigation route beforehand, reducing actual delivery time while maintaining manageable automation levels through preparatory processing.

AI summary
An unmanned delivery system in a marine vessel includes an acquisition unit to acquire destination information of a cargo to be delivered, an automatic navigation unit to cause a marine vessel to automatically navigate in an unmanned manner to a destination port indicated by the destination information, and a controller configured or programmed to issue an arrival notification and perform a fixed point holding of the marine vessel when the marine vessel arrives at the destination port.
