Vessel Display System Automatic Berthing Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vessel display systems for small vessels face challenges in seamlessly transitioning from autopilot mode to automatic berthing mode, particularly when approaching a berthing target position, as they require manual intervention and lack clear, useful information for the user regarding the planned route and berthing target position.
Innovation Solution
A vessel display system that includes an autopilot screen for course control, an automatic berthing control screen for propulsion and steering, a destination approach condition judging unit, and a screen transition control unit to automatically switch between these modes based on predefined conditions, providing detailed maps and allowing touch panel operations for setting and changing destinations and berthing targets without coordinate input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the autopilot screen is displayed with a standard map scale, then the current position and destination are visible, but the berthing target position cannot be clearly distinguished when close to the destination
Solution Approach 1:
The map display scale is made dynamically adjustable based on the vessel's proximity to the destination. When the vessel approaches the destination, the system automatically switches from a standard overview scale to an enlarged scale, allowing the berthing target position to be clearly distinguished while maintaining context awareness through historical scale storage and switching.
Solution Approach 2:
The system pre-stores historical map display scales before enlargement occurs. When the vessel approaches the destination and scale enlargement is needed, the system restores the previous scale after the enlargement period, ensuring smooth transitions and maintaining user orientation without manual intervention.
2Ease of operation
If manual screen switching is required between autopilot and automatic berthing modes, then system control is precise, but operation convenience deteriorates
Solution Approach 1:
The system continuously monitors the vessel's real-time position relative to the destination and provides feedback by automatically triggering screen transitions when predefined conditions are met. This feedback mechanism eliminates manual switching requirements while maintaining precise control through condition-based automation.
Solution Approach 2:
The display system performs self-service by automatically detecting when the vessel approaches the destination and autonomously switching between autopilot and automatic berthing mode screens, eliminating the need for manual operator intervention while maintaining system precision.
3Ease of operation
If coordinate input is required for destination setting, then positioning precision is high, but ease of operation deteriorates
Solution Approach 1:
The system replaces manual coordinate input (mechanical operation) with touch panel-based graphical interaction. Users can directly touch or drag the destination point on the map interface, which automatically converts the visual position into precise coordinate data, maintaining accuracy while dramatically improving ease of operation.

AI summary
A vessel display system includes a display device, an autopilot screen display unit displaying on the display device an autopilot screen for an autopilot mode, an automatic berthing control screen display unit displaying on the display device an automatic berthing control screen for an automatic berthing mode of automatically controlling a propulsion device and a steering mechanism to make the vessel berth at a berthing target position, a destination approach condition judging unit judging whether or not a predetermined destination approach condition, indicating that the vessel has come close to the destination, is satisfied, and a screen transition control unit automatically making the display on the display device transition from the autopilot screen to the automatic berthing control screen when the destination approach condition judging unit judges that the destination approach condition is satisfied.
