Pressure Vessel Lifting Ring With Nut-Seated Socket Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ring nuts used for securing objects in place, particularly in pressure vessels, often fail to withstand strong pulling forces and may not comply with necessary standards for pressure vessels, leading to potential equipment failure and irreversible damage.
Innovation Solution
A ring apparatus with a loop portion and a base portion featuring a socket with a lip for seating a nut, allowing secure attachment to pressure vessels without requiring threaded members, and utilizing nuts that meet compliance standards, such as DIN EN 10204, AD-W7-1, AD-W7-2, and PED2014/68/EU, ensuring robust and safe fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional ring nuts are used to secure objects in pressure vessels, then the structure is simple and easy to manufacture, but they fail to withstand strong pulling forces and may not comply with necessary standards
Solution Approach 1:
The ring apparatus is divided into distinct functional segments: a loop portion for attachment and a base portion with socket for securing to the pressure vessel. This segmentation allows each part to be optimized for its specific function, with the base portion providing structural strength and the loop portion providing attachment capability.
Solution Approach 2:
The ring apparatus serves as an intermediary component between the pressure vessel and external objects (chains, ropes, fasteners). It transfers and distributes pulling forces through its structured design, preventing direct stress concentration on the pressure vessel while providing secure attachment points.
2Reliability
If traditional ring nuts are used, then the device is simple to operate, but they may lead to equipment failure and irreversible damage due to non-compliance with standards
Solution Approach 1:
The ring apparatus incorporates specific geometric parameters and material specifications that meet pressure vessel standards. The socket geometry, lip design, and overall dimensional parameters are engineered to comply with standards such as AD-W7-1, AD-W7-2, and PED 2014/68/EU, ensuring reliable and compliant operation.
Solution Approach 2:
The lip structure in the socket provides a pre-engineered seating surface for the nut, distributing loads beforehand and preventing stress concentration that could lead to failure. This design feature anticipates and prevents potential failure modes before they occur.
3Strength
If a secure fastening system is implemented with socket and lip structure, then the fastening strength is improved, but the manufacturing complexity increases
Solution Approach 1:
The socket and lip structures are merged into a single integrated base portion, eliminating the need for separate components. This integration maintains the structural strength and compliance features while simplifying manufacturing by reducing the number of parts and assembly steps required.

AI summary
A ring apparatus (100) for use with a pressure vessel. The ring apparatus having a loop portion (110) that surrounds a loop axis and a base portion (120) connected to the loop portion. The base portion defines a base opening aligned along a base opening axis that is perpendicular to the loop axis. The base portion also defines a socket through which the base opening axis extends. The socket having an open side and a partially closed side. The open side faces toward an interior of the loop portion and receives a nut (200). The partially closed side having a lip on which the nut can seat. The lip defines the base opening. The base opening receives a threaded member of the pressure vessel.
