Three-Piece Pipe Coupling for Easier Sealing and Assembly
Find Innovative SolutionsGenerate Solutions
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 inefficiencies in sealing and preventing separation under internal or external forces.
Innovation Solution
A 3-piece pipe coupling system with pivotal mounts and fastener pads that allows for easy alignment and tightening of pipe elements using a method involving a gasket and pipe connection rings, ensuring secure sealing and resistance to separation forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional pipe coupling design is used, then the pipe elements can be joined, but the installation process becomes difficult and time-consuming
Solution Approach 1:
The pipe coupling is divided into multiple segments (first coupling segment, second coupling segment, third coupling segment) that can be assembled in a modular fashion. Each segment has specific functions (pivotal mounts for alignment, fastener pads for securing) that simplify the overall installation process while maintaining structural integrity
Solution Approach 2:
The coupling segments are pre-configured with pivotal mounts and fastener pads in specific positions before installation. This preliminary arrangement of components allows for easier alignment and assembly during installation, reducing the complexity of the installation process
2Reliability
If a traditional pipe coupling design is used, then the pipe elements can be joined, but the sealing effectiveness is compromised
Solution Approach 1:
The coupling is segmented into multiple parts that work together to create effective sealing zones at each joint. The gasket interacts with each coupling segment independently, ensuring reliable sealing without requiring complex stretching or disassembly operations
Solution Approach 2:
The gasket serves as an intermediary sealing element between the coupling segments and pipe elements. The pivotal mounts and fastener pads work together to position and secure the gasket effectively, ensuring reliable sealing while simplifying the installation process
3Strength
If a traditional pipe coupling design is used, then the pipe elements can be connected, but the resistance to separation forces is insufficient
Solution Approach 1:
The fastening mechanism is divided into multiple fastener pads distributed across different coupling segments. Each fastener pad provides localized securing points that collectively resist separation forces from internal or external pressures, achieving high strength without requiring a single complex fastening system
Solution Approach 2:
The pivotal mounts and fastener pads are combined into an integrated system where the pivotal mounts enable alignment and the fastener pads provide securing. This combination of functions in a unified coupling structure achieves high resistance to separation forces while maintaining reasonable complexity

AI summary
A method of installing a 3-piece pipe coupling to connect a first pipe element to a second pipe element includes the steps of bringing the 3-piece pipe coupling into engagement with a first connection groove located proximate a first pipe element end of the first pipe element and with a second connection groove located proximate a second pipe element end of the second pipe element, the 3-piece pipe coupling comprising three pieces; and tightening the 3-piece pipe coupling about the first and second pipe element ends with a fastener extending through a first fastener pad and through a second fastener pad formed at respective distal ends of two pieces of the three pieces comprising the 3-piece pipe coupling.
