Industrial Conduit Quick Connector With Segmented Compression Leaves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compression fittings are not regularly used in heavy-duty applications, such as media blast systems, where high pressures up to 150 psi or higher are encountered, due to issues with ferrule deformation and frequent leaks or breakages, requiring frequent shutdown and repair.
Innovation Solution
A compression-type fitting system using a compression body with a plurality of arcuate plates or leaves instead of a ferrule, which compresses around the conduit to form a tight seal, and a stowable compression handle system for easy connection and disconnection, allowing for repeated use without deforming key components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional ferrule is used in compression fittings, then the joint can be sealed, but the ferrule deforms under high pressure causing leaks and breakages in heavy-duty applications
Solution Approach 1:
The single ferrule is divided into multiple segmented compression elements (C-shaped elements with resilient portions). Each segment independently compresses against the conduit, distributing the compressive force and preventing the deformation issues that occur with a single rigid ferrule under high pressure.
Solution Approach 2:
The compression elements are made from elastomeric material that changes its physical properties under compression. The material's resilient nature allows it to maintain sealing pressure without permanent deformation, even under the extreme pressures (up to 150 psi or higher) encountered in media blasting applications.
2Productivity
If compression fittings are used in heavy-duty applications, then connection can be made, but frequent shutdowns are required for repair or replacement due to leaks
Solution Approach 1:
The compression elements are designed to be resilient and dynamic rather than rigid. They can dynamically adjust to pressure changes and maintain sealing contact, preventing leaks that would otherwise require shutdowns for repair in traditional static ferrule designs.
Solution Approach 2:
The system uses composite construction with elastomeric compression elements combined with rigid body portions. This combination provides both the flexibility needed for reliable sealing under varying pressures and the structural integrity required for heavy-duty applications, eliminating the frequent failures seen with traditional materials.
3Ease of operation
If a traditional compression fitting system is used, then connection is made, but the process requires tools and significant time
Solution Approach 1:
The compression elements are designed to be self-installing. When the compression nut is tightened, the C-shaped elements automatically engage and compress against the conduit without requiring any additional tools or complex alignment procedures. The resilient portions self-adjust to seal against the conduit surface.
Solution Approach 2:
The compression elements serve multiple functions simultaneously: they provide mechanical attachment to the conduit, create the sealing interface, and accommodate pressure variations. This multi-functionality is achieved in a single integrated component that simplifies the overall connection process and eliminates the need for separate sealing elements or complex assembly steps.
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 system provides a quick, tool-free connection that reduces connection time by over 50% and maintains a durable, leak-proof seal even under extreme conditions, suitable for heavy-duty industrial applications.
Implementation Method 1
When the lock nut is tightened on the compression body, the compression assembly tightens around and engages the conduit to form a tight durable connection between the respective conduit ends
Implementation Method 2
A plurality or set of leaves or plates are utilized rather than a ferrule or compression ring. This replaces the ferrule and permits compression between the nut and the receiving fitting without having to compress or deform the compression component. The leaves are clamped around the conduit (e.g., pipe).
Implementation Method 3
The sharp internal ribs of each leaf function to grip the outside surface of the first conduit
Implementation Method 4
The sealing is done by two internally raised continuous rings which contact the outside surface of the conduit to create two airtight seals

AI summary
A compression-type fitting system for quick connection of two conduits. The system includes a compression body configured to receive a first conduit and a second conduit therein. The system includes a compression lock nut to engage an outer surface of the compression body. Upon tightening, a continuous ring within the compression body facilitates forming a seal between the compression body and the first conduit.
