Virtual Course Creation for Small Boats Using GPS Positional Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Creating and reproducing a loop course for small boats on the water surface is challenging due to the need for buoys that can maintain fixation on varying sea depths, and accurately recreating the course at different locations is difficult.
Innovation Solution
A system that uses positional information acquisition, user interface, and control means to create virtual course data by virtually installing buoys on the water surface, allowing users to easily create and reproduce virtual courses without actual buoy installations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If actual buoys are installed on the water surface to create a loop course, then the course can be physically marked for navigation, but the installation becomes extremely difficult on seas with certain depth and the process requires equivalent labor each time
Solution Approach 1:
The patent uses GPS positional information to create virtual copies of buoy installation positions, storing coordinate data that reproduces the course layout without requiring physical buoys. This digital copying approach eliminates the need for repeated physical installation while maintaining course accuracy.
Solution Approach 2:
The patent replaces the mechanical system of physical buoy installation with an electronic/digital system using GPS receivers, data processing units, and display devices. This substitution eliminates manual labor and physical deployment while maintaining course marking functionality.
2Adaptability or versatility
If physical buoys are used to mark course positions, then the course can be established on the water surface, but accurate reproduction of the course at different locations becomes extremely difficult
Solution Approach 1:
The patent creates a universal course data format using GPS coordinates that can be transported and reproduced at any location. The digital course data can be transferred between different systems and locations, enabling the same course to be recreated universally without site-specific physical installation constraints.
3Reliability
If buoys are installed to create a loop course, then the course structure is established, but the process requires significant labor and time for each installation
Solution Approach 1:
The patent performs preliminary action by capturing and storing GPS positional data during the initial course creation. This pre-captured digital information serves as a template that can be instantly reproduced without repeating the installation process, eliminating repeated time investment while maintaining course structure integrity.

AI summary
The system accepts an operation to be carried out to virtually install installation objects on a water surface, acquires positional information about each point, and creates course data of a course passing through areas to be determined on the basis of installation positions of the installation objects in the order of installation. The system installs installation objects as buoys, creates a guide image to be used to indicate a buoy to be passed next and a direction from the buoy to be passed next to a buoy to be passed further next by using the course data while intending the guide image for a user of a boat configured to travel along the course on the water surface, and displays the created guide image on a display unit arranged on a hull of the boat.
