Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current marine navigation systems fail to recognize the entire marine navigation area surrounding the vessel, leading to inefficiencies in path recalculations and backtracking when encountering unrecognized objects, and lack user-friendly interfaces for adjusting navigation paths.
Innovation Solution
A system and method that allows user input to define a new navigation pathway through a marine navigation area, using touch or joystick inputs to adjust vessel direction, and generates a display image representing the area, enabling user confirmation and adjustment of the path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the navigation system automatically determines the entire marine navigation area and generates paths, then navigation automation is improved, but the system complexity and computational burden increase when encountering unrecognized objects
Solution Approach 1:
The patent introduces an intermediary mechanism where the system automatically determines the marine navigation area and generates initial paths, but provides a user interface as a mediator for users to intervene when unrecognized objects are encountered. This intermediary layer allows the system to maintain automation while reducing computational burden by leveraging user input for path adjustments.
Solution Approach 2:
The system performs self-service by automatically determining the navigation area and generating paths without requiring complete pre-programming of the entire marine environment. The system serves itself by dynamically creating navigation information as needed, reducing the complexity of having to pre-process and store all possible navigation data.
2Reliability
If the system performs path recalculations and backtracking when encountering unrecognized objects, then navigation reliability is improved, but time loss and navigation efficiency deteriorate
Solution Approach 1:
The system performs preliminary actions by automatically determining the marine navigation area and generating initial navigation paths before the vessel encounters unrecognized objects. This preliminary preparation reduces the need for extensive recalculation and backtracking when obstacles are encountered, as the system already has a framework to work with.
Solution Approach 2:
The patent implements feedback mechanisms where the system monitors for unrecognized objects and triggers user notifications. When users provide input about objects or path adjustments, this feedback is incorporated into the navigation system, allowing for efficient path modifications without requiring complete recalculation and backtracking, thus maintaining reliability while reducing time loss.
3Ease of operation
If the navigation system provides automatic path generation, then ease of operation is improved, but user control and adaptability to specific situations deteriorate
Solution Approach 1:
The patent applies dynamics by providing a user interface that allows users to dynamically adjust navigation paths and provide input about unrecognized objects. The system transitions from purely automatic operation to a dynamic state where user control can be activated when needed, maintaining ease of operation through automation while restoring adaptability when users encounter situations requiring human judgment.
Solution Approach 2:
The navigation system serves multiple functions: it automatically determines the marine navigation area, generates paths, monitors for objects, and provides a user interface for human intervention. This multi-functionality allows the system to maintain ease of operation through automation while also providing user control when needed, resolving the contradiction between automatic operation and user adaptability.
4Productivity
If users can directly input path directions via user interface, then navigation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent uses copying by creating a visual representation (display image) of the marine navigation area and the generated path on the user interface. Users interact with this copied visual representation to provide input about path directions, which is then translated into navigation commands. This copying approach simplifies user interaction while maintaining navigation efficiency.
Solution Approach 2:
The display image and user interface elements serve as intermediaries between the user and the navigation system. Users provide input through the interface about path directions, and the system processes this input to adjust navigation. This intermediary layer manages the complexity by providing a standardized interface while maintaining efficient navigation control.

AI summary
A method of controlling navigation for a marine vessel includes receiving a user input via a user input device identifying a path direction with respect to a vessel location of the marine vessel, defining a new navigation pathway through a marine navigation area based on the path direction indicated by the user input, wherein the new navigation pathway includes a set of geographical locations between the vessel location and a navigation target location, generating a display image representing the marine navigation area and the new navigation pathway, and displaying the display image on a user interface display.
