Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity in equipping and deploying submersibles in submarines is due to the need for precise filling with protective liquids to manage pressure equalization, which can lead to membrane damage and reduced service life.
Innovation Solution
A pressure-resistant tubular storage container system that allows submersibles to be stored dry outside the pressure hull, using a piston-cylinder mechanism for deployment and a glycol-water mixture for pressurization, eliminating the need for protective liquids and enhancing service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the storage container is filled with protective liquid for pressure equalization, then the submersible body is protected from corrosion and pressure stress, but the device complexity increases due to precise fluid quantity measurement requirements and membrane sealing complexity
Solution Approach 1:
The invention extracts the submersible body from the protective liquid environment while maintaining pressure equalization through a dry storage container. The body is stored in a dry, pressurized environment rather than being immersed in protective liquid, eliminating the need for complex fluid filling and membrane sealing systems while still protecting against corrosion and pressure stress.
Solution Approach 2:
The invention changes the physical state parameter of the storage environment from liquid-filled to dry pressurized. By maintaining atmospheric pressure inside the dry container through pressure equalization systems, the submersible body is protected without requiring immersion in protective liquids, thereby simplifying the overall system.
2Reliability
If the storage container uses membrane sealing for pressure equalization, then the submersible body is protected from pressure stress, but the manufacturing precision requirements increase to prevent membrane damage
Solution Approach 1:
The invention removes the membrane sealing component entirely by using a rigid, pressure-resistant container structure. Pressure equalization is achieved through controlled ventilation systems rather than flexible membranes, eliminating the manufacturing precision requirements associated with membrane installation and sealing.
Solution Approach 2:
The invention replaces expensive, precision-critical membrane seals with simpler, more robust pressure equalization mechanisms that are easier to manufacture and maintain, reducing both initial manufacturing costs and long-term maintenance requirements.
3Adaptability or versatility
If the storage container is designed for pressure equalization with protective liquid, then the submersible can be deployed at various diving depths, but the loading time increases due to time-consuming filling procedures
Solution Approach 1:
The storage container is pre-filled with pressurized air or inert gas during manufacturing, eliminating the need for time-consuming on-site liquid filling operations. The pre-prepared pressurized environment allows for immediate loading of submersible bodies without waiting for fluid filling and pressure equalization.
Solution Approach 2:
The invention replaces the mechanical process of liquid filling and manual pressure equalization with a pre-pressurized gas system. This substitution eliminates the time-consuming steps of pumping liquid into the container and adjusting pressure levels, allowing for rapid loading while maintaining diving depth capability.
4Object-affected harmful factors
If the submersible body is stored in protective liquid, then corrosion is prevented, but the service life is reduced due to pressure stress and liquid exposure
Solution Approach 1:
The invention stores the submersible body in a dry, pressurized atmosphere filled with inert gas such as nitrogen or pressurized air. This inert environment prevents corrosion by eliminating contact with moisture and corrosive substances while the pressure equalization prevents pressure stress, thereby extending the service life of the submersible body.
Solution Approach 2:
The invention extracts the submersible body from the harmful protective liquid environment and places it in a benign dry pressurized atmosphere. This extraction eliminates both the corrosive effects of liquid exposure and the pressure stress caused by liquid immersion, significantly extending service life while maintaining corrosion protection.
