Nautical Railing Post Assembly Kevel Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing railing systems for nautical vessels, such as barges, lack an efficient and easily installable solution for fall protection that can effectively secure flexible materials like wire ropes and chains, while ensuring structural integrity and safety against falls.
Innovation Solution
A post assembly system comprising a Rail post, Kevel clasp, and eyelets that securely attach to kevels, allowing for angled installation and supporting flexible materials like wire ropes, with a weldless connection to the barge deck, ensuring the system can withstand significant downward forces and maintain fall protection without direct contact with the deck.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional railing system is used on nautical vessels, then fall protection is provided, but the installation is complex and time-consuming
Solution Approach 1:
The railing system is divided into modular components including posts, rails, and connection elements that can be independently manufactured and assembled. The post assembly includes separate elements for attaching to kevels and deck structures, allowing for segmented installation rather than requiring complex monolithic structures to be installed as one piece.
Solution Approach 2:
Connection elements are pre-designed and pre-configured to match specific kevel and deck structures. The post assembly incorporates pre-formed attachment mechanisms that are prepared in advance for quick installation, eliminating the need for on-site fabrication or complex assembly procedures.
2Stability of the object's composition
If the railing system directly contacts the deck, then structural stability is improved, but the aesthetic appearance and corrosion resistance deteriorate
Solution Approach 1:
A kevel element serves as an intermediary component between the post assembly and the deck structure. The post assembly attaches to the kevel rather than directly to the deck, creating a protective layer that prevents direct metal-to-deck contact. This intermediary structure maintains structural stability while protecting against corrosion and improving aesthetic appearance.
3Adaptability or versatility
If flexible materials like wire ropes are used for rails, then adaptability and ease of installation are improved, but the ability to withstand forces deteriorates
Solution Approach 1:
The railing system separates the flexible rail elements from the structural support components. Wire ropes or other flexible materials are used for the rails themselves, while rigid post assemblies provide the structural framework. This segmentation allows flexible materials to be used where adaptability is needed while maintaining strength through the rigid support structure.
Solution Approach 2:
The post assembly is pre-engineered with connection elements that are prepared in advance to securely attach flexible rail materials. The connection design anticipates the need to accommodate flexible materials while maintaining structural integrity, allowing for easy installation of adaptable rail configurations without compromising force resistance.

AI summary
Fall protection structures are disclosed relating to nautical vessels that include a nautical vessel, a precipice, a first and a second kevel adjacent to the precipice, a first post structure connected to the first kevel, a second post structure connected to the second kevel, a top railing connecting the first post structure to the second post structure, and a middle railing connecting the first post structure to the second post structure such that the top railing and the middle railing limit access to the precipice.
