Maritime Navigation Server Using Vessel Size Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional marine navigation systems are inadequate for small vessels, as they lack affordable and reliable navigation equipment, leading to increased accidents, particularly near coastal areas, due to the complexity of sea routes which vary by vessel size, water depth, and tidal conditions, and existing technologies require expensive AIS devices or measurement instruments for accurate route guidance.
Innovation Solution
A wireless communication terminal-based marine navigation system that includes a server system capable of receiving vessel position and size information to provide updated sea route maps, using past navigation records to adjust route guidance and reliability, allowing for safer navigation without the need for expensive AIS devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If expensive AIS devices or measurement instruments are used for accurate route guidance, then navigation reliability is improved, but device cost increases
Solution Approach 1:
The patent uses GPS position information from ordinary wireless communication terminals to create virtual navigation records that copy the functionality of expensive AIS devices. By accumulating and analyzing position data from multiple vessels, the system recreates navigable route information without requiring specialized expensive equipment on each vessel.
Solution Approach 2:
The system enables ordinary wireless communication terminals with GPS to serve their own navigation needs by automatically collecting position information and utilizing the server's processing capabilities. Vessels don't need specialized AIS equipment - they use their existing GPS-capable terminals to receive customized route guidance based on their vessel size and accumulated navigation data.
2Device complexity
If conventional land navigation technology is applied to marine vessels, then device simplicity is improved, but navigation accuracy deteriorates due to lack of vessel size consideration
Solution Approach 1:
The patent applies local quality by customizing navigation routes according to specific vessel characteristics, particularly vessel size (displacement). The server stores and processes navigation records segmented by vessel type, providing tailored route guidance that accounts for the specific navigational capabilities and requirements of each vessel category, rather than providing generic routes for all vessels.
Solution Approach 2:
The system changes the parameter of route guidance by incorporating vessel displacement as a key variable. The server creates separate navigable route information for different vessel size categories (e.g., under 5 tons, 5-10 tons, over 10 tons), dynamically adjusting recommended routes based on water depth, tidal conditions, and vessel-specific navigational constraints.
3Reliability
If detailed marine safety information is provided to all vessels, then navigation safety is improved, but information processing complexity increases
Solution Approach 1:
The patent extracts and separates the complex information processing function from individual vessels and concentrates it in a centralized server. The server accumulates position information from multiple vessels, processes marine safety data, tidal information, and weather conditions, then provides simplified customized route guidance to each vessel based on its specific characteristics and current location.
