Small Watercraft Abnormality Positioning and Warning System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small watercraft operations are hindered by reduced visibility due to waves, leading to potential navigation errors and collisions, as there are no clear signs or warnings for abnormal situations like a passenger falling overboard or mechanical failures.
Innovation Solution
An operation assistance system for small watercraft that includes a position specification unit to identify abnormality occurrence positions, a transmission unit to send this information, and a processing circuit to create and transmit operation assistance data, which includes a storage unit, an information provision unit, and a warning unit to alert nearby navigational objects of potential hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If no navigation signs or warnings are provided on water, then the watercraft can operate freely without restrictions, but visibility deteriorates and navigational objects may unintentionally enter prohibited areas
Solution Approach 1:
The patent introduces an intermediary system consisting of floating bodies with light sources and communication devices that act as mediators between the watercraft and the environment. These floating bodies provide visual warnings and transmit information about abnormal situations without restricting watercraft operation, resolving the contradiction between navigation freedom and information loss
Solution Approach 2:
The patent replaces traditional mechanical navigation signs with optical signals (lights) and electronic communication systems. The light sources and communication devices transmit warning information electronically and optically, substituting physical mechanical signs with more effective information transmission methods that work better in water environments
2Ease of operation
If navigation prohibited areas are not marked, then watercraft can move freely across the water surface, but abnormal situations go unnoticed and safety is compromised
Solution Approach 1:
The patent implements feedback mechanisms where floating bodies detect abnormal situations (such as passengers falling overboard) and automatically transmit warning information to other watercraft and authorities. This feedback system maintains movement freedom while ensuring safety through automated detection and communication of abnormal conditions
Solution Approach 2:
The patent employs preliminary action by pre-positioning floating bodies in navigation prohibited areas and abnormal situation detection points before any incidents occur. These floating bodies are ready to provide warnings and detect abnormalities in advance, ensuring safety without restricting normal watercraft operations

AI summary
An operation assistance system for a small watercraft includes: a position specification unit that specifies an abnormality occurrence position, which is a position where an abnormality has occurred, when the abnormality has occurred in a small watercraft; a transmission unit that transmits information on the abnormality occurrence position specified by the position specification unit; and a processing circuit, in which the processing circuit includes a storage unit that stores information on the abnormality occurrence position transmitted from the transmission unit, and an information provision unit that creates predetermined operation assistance information based on information on the abnormality occurrence position stored in the storage unit and transmits the created operation assistance information.
