Float-Triggered Vessel Flotation for Rapid Capsize Buoyancy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water vessel flotation systems fail to automatically and quickly provide buoyancy in response to capsizing or hull breaches, which can lead to sinking and potential loss of life and property.
Innovation Solution
A water vessel flotation system comprising inflatable bladders that can be automatically inflated with compressed gas using omni-directional float triggered valves, which are activated by a lever with a flexible link and float, ensuring rapid inflation in the event of capsizing or hull rupture, with the bladders anchored to the vessel's structure and connected to compressed gas storage tanks via manifolds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If manual operation is used to fill flotation tanks with compressed gas, then system complexity is reduced, but response time is too slow to prevent sinking
Solution Approach 1:
The flotation system automatically activates through a self-service mechanism: when water enters the vessel, it triggers the compressed gas tanks to automatically fill the flotation bladders without requiring manual operation. This resolves the contradiction by enabling rapid automatic response while keeping the system simple and reliable.
Solution Approach 2:
The compressed gas is pre-stored in high-pressure tanks before any emergency occurs. This preliminary preparation allows the system to respond immediately when triggered, achieving fast response time without complex real-time compression equipment.
2Reliability
If automatic float-triggered valves are used, then response time is reduced to 30-60 seconds, but device complexity increases
Solution Approach 1:
The patent replaces complex electronic or mechanical sensors with a simple float-triggered valve mechanism. The float responds to water level changes through basic buoyancy, mechanically opening the valve to release compressed gas. This achieves reliable automatic activation while minimizing device complexity through elegant mechanical simplicity.
3Quantity of substance
If multiple compressed gas tanks are installed, then sufficient buoyancy is ensured, but weight and space requirements increase
Solution Approach 1:
The system uses compressed gas stored at high pressure in relatively small tanks, changing the physical parameter of gas density to achieve large buoyancy capacity in compact form. This allows sufficient flotation capability while minimizing the weight and space required for gas storage.
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
The system rapidly inflates bladders to prevent sinking, providing effective buoyancy within 30-60 seconds, ensuring the vessel remains afloat even in severe conditions, and can be manually activated to prevent capsizing before significant damage occurs.
Implementation Method 1
A float is attached to the flexible link after exiting the eyelet allowing the buoyant action of the float in any direction to cause the flexible link to be pulled toward the eyelet
Implementation Method 2
A water vessel flotation system comprising a plurality of inflatable bladders disposed within a vessel. Inflation of the bladders can be performed by one or more omni directional float triggered valves coupled between the compressed gas tanks and the bladders
Data Source
AI summary
A water vessel flotation system is disclosed comprising a plurality of inflatable bladders disposed within a vessel. In the event of capsizing or hull rupture, the bladders can be automatically inflated with compressed gas. Inflation of the bladders can be performed by one or more omni directional float triggered valves coupled between the compressed gas tanks and the bladders. Each valve is operated by a lever having a flexible link (e.g. a chain) attached to its end. The flexible link extends somewhat perpendicularly away from the lever end to pass through an eyelet at distal point. A float is attached to the flexible link after exiting the eyelet allowing the buoyant action of the float in any direction to cause the flexible link to be pulled toward the eyelet and thereby pulling the lever end and opening the valve.
