Pipe Connector Assembly for Stable Mechanical Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection devices for tubular elements fail to provide a stable mechanical seal and are often complex, requiring additional components and difficult maintenance, especially under high-pressure fluid conditions.
Innovation Solution
A connection device comprising a hollow external body, an internal adapter element, and an entirely elastic internal clamping element with anchoring portions that cooperate to form a single body, ensuring a stable coupling and easy installation/uninstallation without additional components or complex operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connectors with multiple components (nut, elastic ring, guiding element) are used, then the connection can be established between pipes, but the mechanical seal becomes unstable over time and components may detach
Solution Approach 1:
The patent combines multiple separate components (nut, elastic ring, guiding element) into a single integrated connector body. The connector comprises a body with an internal cavity that houses both the elastic ring and guiding elements, eliminating the need for separate nuts and reducing component detachment risks while maintaining mechanical seal stability.
Solution Approach 2:
The connector body is segmented into functional zones: an external portion for pipe engagement, an internal cavity for housing components, and specific regions for the elastic ring and guiding elements. This segmentation allows each component to perform its function while being securely positioned within the integrated structure.
2Reliability
If additional components and complex workings are used to connect the nut and elements, then the connection can be established, but maintenance and replacement operations become difficult
Solution Approach 1:
By integrating all connection components into a single connector body, the patent simplifies maintenance operations. The entire connector can be removed and replaced as one unit, eliminating the need to disassemble and reassemble multiple separate components, thereby facilitating easier maintenance and replacement while maintaining connection stability.
3Device complexity
If the elastic ring acts as a passive gripping element only, then the structure is simple, but the mechanical seal is poor and components can detach
Solution Approach 1:
The patent merges the passive elastic ring with active guiding elements and the connector body structure. The elastic ring works in conjunction with guiding elements that actively position and secure the pipe, transforming the system from a simple passive grip to an integrated active-sealing mechanism that prevents component detachment while maintaining reasonable structural simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a reliable and stable mechanical seal between the pipes and connection device components, facilitating easy installation and maintenance while maintaining the connection under pressure.
Implementation Method 1
the second element disposed coaxial with the elastic ring, to guide the correct positioning of the first pipe. The screwing of the second pipe on the nut causes an axial movement of the second element inside the first pipe, with consequent narrowing of the elastic ring so as to clamp the latter axially with the first pipe.
