Segmented Pipe Coupling With Split Rings for Leak-Resistant Assembly

Solution Overview

Problem

Existing pipe coupling designs are difficult to install and require multiple steps, often necessitating the disassembly of the apparatus and stretching of a gasket to join pipe elements, which can lead to leaks and separation under internal or external forces.

Innovation Solution

A pipe coupling system featuring coupling segments with ring grooves and split ring connection rings that compress radially to secure the gasket in place, allowing for easier assembly and secure sealing of pipe elements without the need for extensive disassembly or gasket stretching.

1Ease of operation

If traditional pipe coupling designs are used, then the joint can be sealed, but the installation process becomes difficult and time-consuming requiring disassembly and gasket stretching

Engineering Contradiction:

Improveease of installationVSAvoidinstallation time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The coupling device is divided into multiple coupling segments (e.g., first coupling segment, second coupling segment) that can be independently positioned and assembled. Each segment has its own gasket engagement features, allowing sequential installation without requiring complete disassembly of the apparatus. This segmentation enables the coupling to be installed in simpler steps while maintaining sealing integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The coupling segments are designed with pre-formed gasket engagement features (such as grooves, channels, or contact surfaces) that are prepared in advance during manufacturing. This preliminary configuration eliminates the need for on-site gasket stretching or complex assembly operations, allowing the gasket to be simply positioned and secured between the coupling segments during installation.

Solution Approach 2:

The coupling segments are designed to work together as an integrated system where the gasket is secured between multiple segments that collectively provide the sealing function. The segments are combined through fastening mechanisms (such as fasteners, welds, or mechanical interlocks) to form a unified coupling structure that maintains reliable sealing while simplifying the overall installation process compared to traditional single-piece couplings.
