Submarine Hatch Insert Frame Segmentation for Automated Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for opening and closing submarine hatches delimited by a shaft are complex and difficult to automate, requiring manual maneuvers and additional measures like hammer blows due to the wedge-shaped insert frame's secure attachment during pressure, which increases the risk of injury and reduces efficiency.
Innovation Solution
A method where the insert frame and wedge are designed to be removable separately from the shaft, allowing for easier handling and automation by using a combination of connecting means, shock clamps, and lifting devices to facilitate opening and closing, enabling the frame to be lowered into the submarine without complex turning maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insert frame is designed as a wedge-shaped bulkhead that fits precisely into the tapered shaft, then the hatch can be securely closed and the pressure hull stability is ensured, but the insert frame becomes firmly attached to the shaft during diving and requires additional measures like hammer blows for removal
Solution Approach 1:
The insert frame is divided into multiple segments or sections that can move relative to each other. During removal, these segments can shift or detach sequentially, allowing the insert frame to be extracted from the tapered shaft without requiring excessive force or additional tools like hammer blows.
Solution Approach 2:
The insert frame incorporates dynamic elements such as movable bulkheads or adjustable support structures that can change their position or configuration during removal. This dynamic capability allows the insert frame to adapt to the removal process, reducing friction and engagement with the tapered shaft, thereby facilitating easier extraction.
2Reliability
If the insert frame is designed as a wedge-shaped bulkhead, then it can be securely positioned in the shaft, but it requires complex turning and rotating maneuvers to be stowed inside the submarine during cargo loading
Solution Approach 1:
The insert frame is segmented into multiple sections that can be independently manipulated or reconfigured. This segmentation allows the insert frame to be folded, collapsed, or disassembled into a more compact form, eliminating the need for complex turning and rotating maneuvers during stowing operations.
Solution Approach 2:
The insert frame incorporates dynamic mechanisms such as telescopic sections, hinged bulkheads, or adjustable support structures that enable the frame to transform its shape and size. This dynamic capability allows the insert frame to be easily stowed in a compact configuration without requiring complex manual maneuvers, and can be rapidly deployed when needed.
3Ease of operation
If the insert frame is made shorter than the shaft dimensions to allow direct lowering into the submarine interior, then complex turning maneuvers are eliminated, but the structural integrity and stability of the pressure hull may be compromised
Solution Approach 1:
The insert frame incorporates dynamic elements such as telescopic sections, extendable bulkheads, or adjustable support structures that allow the frame to expand or contract. When deployed in the shaft, the insert frame can extend to its full length to provide adequate structural support and stability. When stowed, it can be compressed or folded to a shorter configuration, allowing direct lowering into the submarine interior without complex maneuvers.
Solution Approach 2:
The insert frame is constructed using composite materials or advanced structural designs that provide high strength-to-weight ratio and exceptional structural efficiency. This allows the insert frame to be made shorter while still maintaining the necessary structural integrity and stability when deployed, as the composite materials compensate for the reduced length through superior mechanical properties.
