Modular Hose End Fitting for Replaceable High-Pressure Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible hoses used in wellhead sites fail prematurely due to operational conditions such as high pressures, vibrations, and corrosion, leading to increased operational inefficiencies and costs as the entire hose must be replaced when end components fail.
Innovation Solution
A modular end fitting apparatus for flexible hoses that allows for the replacement of end components without replacing the entire hose, featuring a monolithic end body with threaded engagement and sealing mechanisms, enabling easy installation and removal of removable end fittings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire flexible hose is replaced when end components fail, then the hose can be restored to full functionality, but the operational lifespan is shortened and costs increase
Solution Approach 1:
The hose assembly is divided into separable components: the flexible hose body and the end fitting. The end fitting can be independently replaced without replacing the entire hose, allowing the hose body to continue serving its function while only the failed end component is swapped out.
Solution Approach 2:
When the end fitting fails, only that specific component is discarded and replaced, while the functional hose body is recovered and retained for continued use. This selective replacement approach extends the overall operational lifespan of the hose system.
