Segmented Coupling Device for Pipe Joint Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipe joints in underground water systems lack integrity due to misalignment and ground movement, leading to frequent disengagement and costly repairs, especially when using shorter pipes that require multiple connections and are difficult to maneuver.
Innovation Solution
A coupling device comprising encircling devices connected by spanning elements, which securely nest around the pipe corrugations to reinforce the joint, increasing the tightness and durability of pipe connections and facilitating easier installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If shorter pipes are used to facilitate transportation and maneuverability, then ease of operation and transportation efficiency are improved, but the number of pipe joints increases and joint integrity deteriorates
Solution Approach 1:
The coupling device is segmented into two separate pipe encircling devices that can be independently positioned on adjacent pipes and connected by a spanning element. This segmentation allows the device to be installed on shorter, more maneuverable pipes while maintaining joint integrity through the connecting spanning element that bridges the gap between pipe sections.
2Productivity
If multiple pipe connections are made using shorter pipes, then transportation and handling efficiency are improved, but the frequency of disengagement and maintenance requirements increase
Solution Approach 1:
The invention merges the function of multiple separate coupling devices into a single integrated spanning element that connects two pipe encircling devices. This combination reduces the total number of connection points and potential failure zones, thereby decreasing maintenance frequency while allowing the use of shorter, more manageable pipe sections that improve installation efficiency.
3Device complexity
If conventional pipe joints are used without reinforcement, then device complexity is reduced, but joint stability under ground movement and pressure variations deteriorates
Solution Approach 1:
The spanning element acts as an intermediary component that connects the two pipe encircling devices, providing additional structural support and stability to the joint. This intermediary element distributes mechanical stresses and resists ground movements and pressure variations without requiring complex reinforcement structures on the pipes themselves.

AI summary
A coupling device may increase the integrity of a pipe joint. The coupling device may include a first pipe encircling device and a second pipe encircling device connected across the pipe joint by a spanning element. The pipe encircling device may be made up of at least two approximately c-shaped segments. The multi-part nature of the pipe encircling devices may facilitate installation of the coupling device at an excavation site.
