Submarine Rescue Device External Drive Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing submarine designs require complex pressure hull modifications and risk jamming issues when storing and deploying submarine rescue devices (URGs) between the pressure hull and outer skin, which can impede emergency use.
Innovation Solution
A submarine design featuring a URG mounted between the pressure hull and outer skin with a linear drive outside the pressure hull contour, utilizing a pneumatically actuable lifting cylinder and a chain drive mechanism to move the URG to a position outside the outer skin, along with a storage rack and holding elements to prevent jamming and ensure secure deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the URG is stored between the pressure hull and outer skin with a linear drive inside the pressure hull, then the URG can be deployed, but the pressure hull structure becomes complex requiring recesses that compromise pressure resistance
Solution Approach 1:
The linear drive mechanism is extracted from the interior of the pressure hull and relocated to the exterior surface. This allows the URG to be actuated from outside the pressure hull, eliminating the need for internal recesses that would compromise the pressure-resistant structure. The drive mechanism operates independently on the outer surface while still enabling URG deployment.
Solution Approach 2:
The solution transitions the linear drive from a three-dimensional interior space-consuming arrangement to a two-dimensional surface-mounted configuration. By placing the drive on the outer surface of the pressure hull rather than inside, the system utilizes the external surface area instead of internal volume, avoiding interference with the pressure hull's structural integrity.
2Adaptability or versatility
If the URG is moved through a small opening in the outer skin, then the URG can be deployed, but jamming risk increases during movement
Solution Approach 1:
The linear drive mechanism is extracted and positioned externally, allowing the URG to be actuated from the outside without needing to pass through restrictive openings in the pressure hull or outer skin. The URG can move more freely in the external environment, reducing jamming risks associated with constrained movement through small apertures.
3Ease of operation
If the linear drive is arranged inside the pressure hull, then the URG can be actuated, but the pressure hull design becomes more complex
Solution Approach 1:
The linear drive is extracted from the pressure hull interior and repositioned on the external surface. This simplifies the pressure hull design by removing the need for internal mounting structures, recesses, and associated complexities, while the URG can still be effectively actuated through the externally positioned drive mechanism.

AI summary
The boat has a press-body (2) and an outer shell surrounding the press-body. A submarine boat rescue device (6) is supported between the press-body and the shell. A linear drive is arranged outside an outer contour of the press-body for processing the rescue device from a bearing position into a position outside the shell. A movable bearing (8) is movably coupled with the drive. The bearing is arranged in a bearing frame (4) that is reinforced to the press-body. The rescue device is flexibly fixed in a bearing position in a direction transverse to an extended direction.
