Integrated Coupling Device for Underwater Rescue Submarine Evacuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current underwater rescue methods face challenges in quickly and safely evacuating personnel from submarines at great depths due to high ambient pressure, which can lead to buoyancy issues and increased risk of diving sickness, as well as the complexity of managing separate connections for breathing air and fixation during the rescue process.
Innovation Solution
A coupling device that integrates a mechanical connection and breathing air supply between the underwater rescue suit and the submarine, allowing for simultaneous detachment of both connections, reducing the time spent under high pressure and enhancing safety by automating the release mechanism, particularly through quick coupling and delay circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a rescue suit with high buoyancy (approximately 500 N) is used for rapid ascent, then the ascent speed and rescue time are improved, but the person becomes extremely difficult to secure during the lock process and may float up and block the lock
Solution Approach 1:
The patent combines the mechanical connection for securing the person and the breathing air supply connection into a single integrated coupling device. This allows both connections to be made and released simultaneously, simplifying the operation during the lock process and ensuring that the person remains securely positioned despite the high buoyancy force of 500 N.
Solution Approach 2:
The coupling device is designed with separate functional components: a mechanical connection element for force transmission and a breathing air supply element, both integrated into a single coupling mechanism. This segmentation allows independent optimization of each function while maintaining simultaneous operation.
2Adaptability or versatility
If separate connections for mechanical securing and breathing air supply are used, then each function can be optimized independently, but the release process becomes more complex and time-consuming
Solution Approach 1:
The patent merges the mechanical connection and breathing air supply connection into a single integrated coupling device that can be connected and disconnected as one unit. This reduces the complexity of managing multiple separate connections while maintaining the functional benefits of both systems.
3Extent of automation
If multiple separate connections need to be disconnected during release, then each connection can be independently controlled, but the total release time increases and exposure to high pressure is extended
Solution Approach 1:
The integrated coupling device allows simultaneous disconnection of both the mechanical connection and breathing air supply connection through a single release action. This dramatically reduces the release time and minimizes the person's exposure to high ambient pressure during the evacuation process.
4Reliability
If the mechanical connection is designed to withstand high buoyancy forces (500 N), then the securing reliability is improved, but the coupling device becomes more complex and difficult to operate
Solution Approach 1:
The patent integrates the high-strength mechanical connection into a compact coupling device that combines both securing and breathing air supply functions. This integration maintains the reliability needed to withstand 500 N buoyancy forces while simplifying the overall operation through a single coupling mechanism.
