Boat Navigation System for Shore Arrival Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems for large boats cannot accurately guide them to shore arrival locations due to unknown shapes of piers or quays, requiring manual visual confirmation.
Innovation Solution
A navigation system equipped with a sensing device that generates environment information and an environment map creator, which creates a map indicating the shape of the shore arrival location, allowing for automatic guidance of the boat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic boat operation is used based on longitude and latitude, then the boat can arrive at the destination automatically, but the shape of the shore arrival location is unknown requiring manual visual confirmation
Solution Approach 1:
The system performs preliminary mapping of the shore arrival location's shape and surrounding structures before the boat arrives. The environment map is created in advance using sensing device data, allowing the automatic operation system to have advance knowledge of the destination geometry and plan the approach trajectory accordingly.
Solution Approach 2:
The system creates a digital copy (environment map) of the physical shore arrival location's shape and surrounding structures. This environmental map serves as a virtual representation that the navigation system can use for automatic guidance, eliminating the need for visual confirmation while maintaining complete information about the destination.
2Loss of information
If manual operation with visual confirmation is used, then the shape of the shore arrival location can be confirmed, but the boat cannot arrive automatically at the destination
Solution Approach 1:
The system creates a digital copy (environment map) of the physical shore arrival location's shape and surrounding structures. This environmental map serves as a virtual representation that the navigation system can use for automatic guidance, eliminating the need for visual confirmation while maintaining complete information about the destination.
Solution Approach 2:
The system replaces the mechanical visual confirmation process with an electronic sensing and mapping system. The sensing device captures environmental data and the environment map creator generates a digital representation, substituting human visual inspection with automated electronic detection and processing.
3Loss of information
If the environment map is created using sensing device, then the shape of the shore arrival location is known, but the system complexity increases
Solution Approach 1:
The sensing device serves multiple functions: it maps the shore arrival location shape, identifies surrounding structures, and provides navigation data. By making the sensing device multi-functional, the system avoids adding separate dedicated components for each function, thereby reducing overall system complexity while still achieving comprehensive environmental awareness.
