Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional hydraulic connector assemblies require two workers to install and often struggle with centering and reliable deformation of gaskets, especially when dealing with complex forms and tight spaces, such as within tanks with small entry points.
Innovation Solution
A gasket with inclined profiles and a centering portion that allows for single-sided installation and reliable deformation, ensuring precise and efficient sealing by guiding the deformation of the gasket portions and providing a secure seal with a tubular design and annular coupling elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connector assemblies use two ring nuts with gaskets inserted from opposite sides of the wall, then reliable sealing can be achieved, but installation requires two workers and is time-consuming
Solution Approach 1:
The gasket is segmented into a first portion and a second portion, where the first portion remains on the external side of the wall and the second portion is inserted into the tank through the connection seat. This segmentation allows the gasket to function effectively while being installed from a single side, eliminating the need for two workers.
Solution Approach 2:
The gasket transitions from a traditional annular shape to a three-dimensional configuration with inclined profiles. The inclined surfaces allow the gasket to deform and seal effectively against the connection seat while being compressed from the external side only, adding a dimensional aspect to the sealing mechanism.
2Reliability
If traditional gaskets have complex forms to ensure sealing, then sealing performance can be improved, but centering on the cylindrical connector body becomes difficult
Solution Approach 1:
The gasket incorporates inclined profiles that create curved, tapered surfaces. These inclined surfaces naturally guide the gasket onto the cylindrical connector body, self-centering it during installation. The curvature of the inclined profiles works with the cylindrical geometry to ensure proper alignment without requiring complex centering procedures.
3Reliability
If deformable gaskets are used to achieve sealing, then sealing can be obtained, but predictable and correct deformation is not guaranteed under various working conditions
Solution Approach 1:
The gasket's geometry is precisely controlled with specific inclined profiles defined by angular parameters. These parameter specifications ensure that the gasket deforms in a predictable and controlled manner when compressed, achieving reliable sealing across various working conditions including different pressures and installation tolerances.

AI summary
A gasket for use with a connector assembly apt to allow the sealed passage of a fluid through a wall (P) and suitable for installation realized from just one side of the wall, which gasket has a deformable region is provided. The gasket is configured to assume an installation configuration, in which the gasket can be introduced into a connector seat (D) formed in the wall (P), crossing it from side to side, and a sealing configuration, wherein the gasket is installed in the wall (P) and deformed, at the deformable region, to abut on an inside mouthpiece of the connector seat.
