Route Editing Assistance Device for Simultaneous Navigation Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation route editing techniques, such as the instant track technique, are limited by distance constraints and require multiple user actions, leading to time lag and inability to simultaneously display the original and edited routes for comparison.
Innovation Solution
A route editing assistance device and method that accepts position information for both the original and edited routes, allowing for simultaneous display on a user interface, enabling efficient editing of navigation routes without distance limitations and minimizing time lag through a single user action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the instant track technique is used for route editing, then a temporary track can be created to deviate from or return to the navigation route, but the technique is limited by distance constraints (destination must be within 50 miles) and requires multiple user actions causing time lag
Solution Approach 1:
The system pre-calculates and stores multiple alternative routes along with their conning information before navigation begins. When route editing is needed, the system immediately retrieves pre-computed alternative routes based on current position and vessel characteristics, eliminating the time lag associated with calculating routes in real-time during navigation.
Solution Approach 2:
The system dynamically adjusts the display and selection of alternative routes based on the vessel's current position, speed, and heading. As the vessel moves along the navigation route, the system updates which alternative routes are relevant and displays them accordingly, allowing flexible route changes at any point without distance limitations.
2Adaptability or versatility
If the instant track technique is used for route editing, then a temporary track can be created, but the technique doesn't provide display of both the navigation route under monitoring and the newly created route for comparison
Solution Approach 1:
The system displays alternative routes overlaid on the same navigational chart as the current navigation route, using visual differentiation (such as different line styles or colors) to distinguish between the active route and alternative routes. This allows captains to compare multiple routes spatially on the same display without losing contextual information about the current navigation path.
Solution Approach 2:
The system segments the display to show different route information simultaneously - the navigation route under monitoring is displayed with its conning information, while alternative routes are displayed with their respective conning information, allowing side-by-side comparison of multiple route options without information overload.
3Ease of operation
If the instant track technique is used for route editing, then route deviation can be achieved, but the technique requires several user actions before creating a new route
Solution Approach 1:
The system automatically retrieves and displays alternative routes based on the vessel's current position and pre-stored route data. When a captain initiates route editing, the system self-services by immediately presenting relevant alternative routes without requiring the captain to manually input parameters or navigate through multiple configuration steps, thereby simplifying the operation.
Solution Approach 2:
The system performs preliminary calculations and stores multiple alternative routes with complete conning information before navigation begins. This pre-computation allows the system to immediately present ready-to-use alternative routes when editing is requested, eliminating the need for multiple user actions to configure and calculate routes during critical navigation situations.

AI summary
A route editing assistance device for editing a first route is provided. The route editing assistance device includes an input interface, and processing circuitry. The input interface is configured to accept position information indicating positions of a first set of waypoints representing the first route. The processing circuitry is configured to accept position information indicating positions of a second set of waypoints, wherein the second set of waypoints defines a second route, and generate display data for simultaneously displaying the first route and the second route on a display.
