Underwater Mass Storage Device Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for transferring data from underwater pressure hulls are time-consuming due to the need to open and reseal the pressure hull or rely on radio transmission, which is slow for large data sets.
Innovation Solution
A mass storage device with a pressure-resistant, water-impermeable insulating body that can be detachably connected to a connecting device outside the underwater pressure hull, allowing data transfer without opening the hull, using a detachable connection element that prevents electrical short circuits and allows data to be read/write both inside and outside the hull.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mass storage device is arranged inside the underwater pressure hull, then the data can be protected from water ingress, but the transfer of data requires opening and resealing the pressure hull which takes a lot of time
Solution Approach 1:
The system is divided into two separate pressure-resistant components: the underwater pressure hull containing the computing unit, and the detachable mass storage device with its own insulating body. This segmentation allows the mass storage device to be independently connected and disconnected without affecting the integrity of the pressure hull, enabling rapid data transfer while maintaining protection from water ingress.
Solution Approach 2:
The insulating body acts as an intermediary between the mass storage device and the underwater environment. It provides pressure resistance and water impermeability, allowing the mass storage device to function both inside and outside the pressure hull while maintaining data protection. This intermediary enables the device to operate in harsh underwater conditions without requiring the hull to be opened.
2Ease of operation
If the mass storage device has a hermetically sealed housing with air volume, then the device can be removed from the pressure hull, but it takes considerable time to open the body to remove the mass storage device
Solution Approach 1:
The connecting element is designed to be detachable, transforming the static hermetically sealed housing into a dynamic structure that can be quickly connected and disconnected. This dynamic design allows the mass storage device to be easily removed and reattached without time-consuming opening operations, while the insulating body maintains pressure resistance and water impermeability throughout the process.
3Device complexity
If data is transferred wirelessly via radio waves, then the mass storage device can remain in place, but the transfer time depends on transmission properties and data size which is slow for large data sets
Solution Approach 1:
The mass storage device is extracted from the underwater pressure hull and connected to the computing unit via a detachable connecting element. This extraction allows for direct physical access to the storage device, enabling rapid data transfer by removing the storage device itself rather than transferring data through wireless transmission or opening the pressure hull.
4Productivity
If the mass storage device is detachably connected outside the pressure hull, then data transfer is rapid and independent of data size, but the device must be pressure-resistant and water-impermeable
Solution Approach 1:
The insulating body is designed to provide multiple functions simultaneously: pressure resistance, water impermeability, and electrical insulation. This multi-functionality allows the mass storage device to operate independently both inside and outside the pressure hull, enabling rapid data transfer while maintaining protection from underwater conditions. The connecting element provides both mechanical attachment and electrical connection functions.

AI summary
The invention relates to an apparatus for transferring data and to a method for transferring data from or to an underwater pressure body 30 having a bulk storage apparatus 10. The bulk storage apparatus 10 is normally located within the underwater pressure body 30, such that only by means of a time-consuming disassembly of the underwater pressure body 30 can the bulk storage apparatus 10 be disconnected from a computation unit 32 of the underwater pressure body 30, and the data of the separate bulk storage apparatus 10 can be transferred by passing on to the bulk storage apparatus 10. The problem of time-consuming transfer of data is solved by means of an apparatus according to the invention which comprises the bulk storage apparatus 10, which has a pressure-resistant insulation body 24 through which water cannot pass and which has no air in it, and which can be detachably connected to a connecting apparatus 36 which is arranged on the outside of the underwater pressure body 30. There is therefore no need to disassemble the underwater pressure body 30 in order to remove the bulk storage apparatus 10, and the time for transferring the data is substantially shortened.
