Submarine Rescue Device Nested in Torpedo Tube
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional submarine rescue devices require significant space and are exposed to high pressures, necessitating complex construction and frequent maintenance, as they are typically stored outside the pressure hull but inside the outer skin of the submarine.
Innovation Solution
Designing a submarine rescue device that fits within a torpedo tube, allowing it to be stored inside the pressure hull and deployed via the tube, with a cylindrical pressure-resistant container housing an automatic inflatable life raft and components, and using a predetermined breaking point for release at the water surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the submarine rescue device is stored outside the pressure hull but inside the outer skin, then it is accessible for deployment, but it requires a relatively large amount of space and is exposed to high diving pressures requiring complex design and frequent maintenance
Solution Approach 1:
The submarine rescue device is nested inside the torpedo tube, which is itself inside the pressure hull. This nested arrangement allows the rescue device to be protected from external pressure while utilizing existing internal space, eliminating the need for separate storage space between outer skin and pressure hull.
Solution Approach 2:
The torpedo tube serves dual functions: its original armament function and as a storage and deployment mechanism for the submarine rescue device. This multi-functionality eliminates the need for dedicated rescue device storage space while maintaining protection from pressure.
2Volume of stationary object
If the submarine rescue device is stored inside the pressure hull in a torpedo tube, then space requirements are reduced and protection from pressure is improved, but deployment complexity increases
Solution Approach 1:
The submarine rescue device is pre-positioned inside the torpedo tube in a ready-to-deploy state. All necessary components are pre-assembled and secured, requiring only the simple action of opening the torpedo tube hatch for deployment, thereby reducing operational complexity despite the internal storage location.
3Adaptability or versatility
If the submarine rescue device is designed to fit through a torpedo tube, then it can be deployed from a submerged state, but the device must have a specific cylindrical shape with limited dimensions
Solution Approach 1:
The submarine rescue device is designed with a cylindrical elongated shape that fits the torpedo tube's cross-sectional dimensions, utilizing the length dimension of the tube for storage. This dimensional adaptation allows the device to be stored internally while maintaining the capability for emergency deployment from submerged state.
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 reduces space requirements, protects the rescue device from external pressures, and enables immediate deployment in emergencies, while allowing the torpedo tube to be used for its original purpose when not needed for rescue operations.
Implementation Method 1
it is also state of the art to generate gas by means of a gas generator inside the submarine in order to provide the necessary buoyancy to lift the boat in an emergency
Implementation Method 2
When the submarine is submerged, this sphere can be released by opening a hatch. Due to its buoyancy, the sphere then floats to the water surface
