Waypoint-Based Navigation Publication Retrieval for Route Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route planning devices require manual searching through nautical charts and paper books for navigation information, which is time-consuming and lacks clarity on previous route settings, making it difficult to easily confirm past navigation publications.
Innovation Solution
A route planning device with a navigation publication database that associates navigation publications with positions on a chart, allowing for easy retrieval and display of relevant publications based on set waypoints, along with a display control module to organize publications by similarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual searching through nautical charts and paper books is used for route planning, then navigation information can be obtained, but it takes a lot of time and is inefficient
Solution Approach 1:
The system pre-stores navigation publication information (such as nautical charts, tide tables, and weather data) in a database before route planning begins. When a user sets waypoints, the system automatically retrieves relevant pre-stored publications instead of requiring manual searching, significantly reducing the time needed to obtain navigation information.
Solution Approach 2:
The system creates a digital copy of navigation publications and stores them in an electronic database. Instead of using physical paper books and charts, the system uses electronic copies that can be quickly searched and retrieved, eliminating the need for manual physical searching and improving efficiency.
2Loss of information
If past route planning information is stored in paper books, then navigation publications can be referenced, but it is not clear on what grounds routes were set and difficult to confirm past publications
Solution Approach 1:
The system creates digital copies of past route planning data including the specific navigation publications used, and stores them in an electronic database. This allows users to easily retrieve and view the exact publications and reasoning behind past route decisions, providing both clarity and ease of access that paper records cannot provide.
Solution Approach 2:
The system provides feedback by automatically displaying relevant past navigation publications and route planning information when users query historical data. This feedback mechanism makes it clear what grounds were used for past route settings and how to access them, resolving the uncertainty about past decision-making bases.
3Loss of information
If navigation publications are stored in paper books, then they can be referenced during route planning, but searching through them is time-consuming
Solution Approach 1:
The system converts physical navigation publications into digital copies stored in an electronic database. These digital copies can be instantly searched and retrieved using computer algorithms, eliminating the time-consuming process of manually flipping through paper books while preserving all the navigation information.
Solution Approach 2:
The system pre-organizes navigation publication data in a structured electronic format with indexes and keywords before route planning begins. This preliminary organization allows for rapid retrieval during route planning without requiring manual searching through unorganized paper materials.

AI summary
A route planning device is provided with a display configured to display a chart on a screen, an operation interface configured to specify a position on the screen, a storage configured to store navigation publication related to a book referred to during past route planning in association with the position, a waypoint setting module configured to set a waypoint on the chart in response to a user's operation received by the operation interface, a navigation publication acquisition module configured to acquire navigation publication within a range of the set waypoint as a reference from the storage, and a display control module configured to display the acquired navigation publication on the screen of the display.
