Pre-Assembled Hose Adapter Coupling for Single-Worker Pipe Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging for a single worker to align and secure pipe elements within slip-on pipe couplings efficiently, often requiring multiple workers, which reduces efficiency and increases assembly time in piping systems.
Innovation Solution
A pre-assembled coupling assembly featuring a coupling with a gasket and a hose adapter with a raised lip and groove configuration, allowing the coupling to be retained in a relaxed position, facilitating easy alignment and secure attachment to a pipe element without the need for multiple workers.

If slip-on pipe couplings are used to connect pipe elements, then the piping system can be assembled, but it requires multiple workers to align and secure the pipe elements, which reduces assembly efficiency and increases man hours
Solution Approach 1:
The hose adapter is pre-assembled with the coupling, and the coupling is retained on the hose adapter in a relaxed position before being installed on the pipe. This preliminary assembly allows the coupling to be easily attached to the pipe by a single worker without requiring alignment of multiple components during installation, thereby improving assembly efficiency while maintaining ease of operation
Solution Approach 2:
The coupling is nested on the hose adapter, with the coupling bore receiving the hose adapter. The coupling includes a gasket that engages with the hose adapter to retain it in position. This nested configuration allows compact assembly and enables single-worker installation while maintaining ease of operation
