Capsize Rescue Signal Layout for Marine Vessels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transmission characteristics of rescue signals from marine vessels are compromised when capsized, as radio waves are attenuated underwater, making it difficult for the signal to reach the rescue destination.
Innovation Solution
A marine vessel is equipped with a transmission source located above the water surface, ensuring that the rescue signal can be transmitted effectively even when the vessel is capsized, using a cellular data communication module or a mobile terminal positioned above the water surface, and optionally an additional transmission source to enhance signal reach.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal or DCM is stored in a waterproof storage box on the hull, then the device is protected from water damage, but when the vessel is capsized the storage box is submerged below the water surface causing radio wave attenuation
Solution Approach 1:
The patent divides the transmission function into two separate transmission sources: one located on the hull (protected from water) and another located above the water surface (unsubmerged during capsizing). This segmentation allows the system to maintain reliable signal transmission regardless of vessel orientation.
Solution Approach 2:
The patent positions the second transmission source in a different spatial dimension (above the water surface) rather than just on the hull. This dimensional change ensures that at least one transmission source remains unsubmerged and capable of transmitting radio waves effectively during capsizing events.
2Ease of manufacture
If the DCM is provided at a location on the hull, then the communication module is easily integrated into the vessel structure, but when capsized the DCM is submerged causing signal attenuation
Solution Approach 1:
The patent segments the communication function across two locations: the DCM integrated into the hull structure for ease of manufacture, and an additional transmission source positioned above the water surface to ensure signal transmission during capsizing.
Solution Approach 2:
The patent changes the positional parameter of the transmission source from solely hull-mounted to including above-water positioning. This parameter change allows the system to maintain communication capability despite changes in vessel orientation and water submersion.
3Device complexity
If a single transmission source is used, then the system is simple and cost-effective, but the rescue signal cannot reach the destination when the transmission source is submerged
Solution Approach 1:
The patent divides the transmission function into two separate transmission sources positioned at different locations. This segmentation increases reliability by ensuring that at least one source remains unsubmerged and functional during capsizing, while keeping each individual source relatively simple.
Solution Approach 2:
The patent pre-positions a second transmission source above the water surface in advance, so that when capsizing occurs, the system immediately has an unsubmerged transmission source available without requiring real-time detection or repositioning actions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration improves the transmission characteristic of the rescue signal, ensuring it reaches the rescue destination without significant attenuation, even when the vessel is capsized, thereby facilitating timely rescue operations.
Implementation Method 1
a transmission source to transmit a rescue signal to a vicinity above a water surface both when the marine vessel is not capsized and when the marine vessel is capsized
Implementation Method 2
since the storage box is often submerged below the water surface when the marine vessel is capsized radio waves (the rescue signal) transmitted from the mobile terminal will be attenuated underwater

AI summary
A marine vessel to improve a transmission characteristic of a rescue signal when the marine vessel is capsized includes a transmission source to transmit a rescue signal to a vicinity above a water surface both when the marine vessel is not capsized and when the marine vessel is capsized.
