Monolithic Pivot Pipe Coupling for Uniform Gap Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe coupling methods require time-consuming and difficult incremental tightening of nuts and bolts, especially when one end is not accessible, leading to inefficiencies and installation challenges.
Innovation Solution
A pipe coupling system featuring a pivot clip that maintains a separation distance between segments, allowing for easier installation by initially placing the pivot clip between the ends of the segments and then tightening the elements to draw the segments together, enabling the insertion of pipes and subsequent tightening to create a uniform gap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional pipe coupling methods are used with two fasteners tightened incrementally and alternatingly, then the coupling space between opposite ends can be kept substantially the same, but the installation process takes significant time and becomes difficult when one end is not accessible
Solution Approach 1:
The pivot clip is pre-installed on the coupling segment before the pipes are inserted. This preliminary positioning of the spacing element allows the coupling to be pre-configured with the correct gap, eliminating the need for time-consuming incremental tightening and enabling faster installation even when access is limited
2Reliability
If traditional pipe coupling methods are used requiring alternating tightening of fasteners, then the coupling can be properly assembled, but the process encounters difficulties when one end is not accessible
Solution Approach 1:
The coupling system is divided into distinct functional components: the coupling segment, the pipes, and the pivot clip spacing element. This segmentation allows the pivot clip to be independently positioned and installed on the coupling segment before pipe insertion, enabling proper assembly even when one end is inaccessible during installation
3Productivity
If pivot clip is used to maintain separation distance between segments, then installation becomes faster and more accessible, but an additional component is introduced to the assembly
Solution Approach 1:
The pivot clip serves as an intermediary component that simplifies the overall installation process. By introducing this dedicated spacing element, the system eliminates the need for complex alternating tightening procedures, and the pivot clip itself can be installed quickly as a preliminary step, improving productivity despite the additional component

AI summary
A coupling segment includes an arcuate segment body defining a first end and a second end opposite the first end; a first shoulder that is formed proximate to the first end and comprises a first fastener pad extending outwardly from the arcuate segment body, the first shoulder further defining an interior edge; and a first pivot extending from the first shoulder at the interior edge, wherein the first pivot is cast monolithically with the arcuate segment body and the first shoulder.
