Split Ring Pipe Fitting Assembly for Faster Joint Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical pipe couplings and fittings require time-consuming and labor-intensive installation processes due to the need for disassembly and reassembly, as they typically involve multiple piece parts and require manual lubrication and alignment of stiff sealing elements.
Innovation Solution
The design of pipe fittings with preassembled housing portions and split rings that maintain a spaced relation, allowing for easy insertion of pipe elements without disassembly, and adjustable connection members that tighten to secure the fitting while deforming the split rings for engagement with the pipe elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mechanical couplings are disassembled and reassembled during installation, then the sealing element can be properly positioned, but the installation time and labor intensity increase significantly
Solution Approach 1:
The coupling is pre-assembled with the sealing element positioned within the channels before installation. The housing portions are pre-bolted together and the sealing element is captured within the segments, eliminating the need for disassembly during installation. This preliminary preparation allows direct installation onto the pipe elements.
Solution Approach 2:
The invention combines multiple functions into a single integrated assembly: the housing portions, sealing element, and connection members are merged into a pre-assembled unit. This eliminates the separate steps of positioning the seal, assembling the housing, and securing the connection, reducing installation complexity and time.
2Ease of operation
If the sealing element is lubricated and stretched to fit pipe elements, then the seal can be installed, but the process becomes difficult and messy
Solution Approach 1:
The sealing element is pre-positioned within the channels of the housing portions during manufacturing, before installation at the job site. This eliminates the need for field lubrication and stretching operations that create messiness and handling difficulties.
Solution Approach 2:
The sealing element is nested within the housing portions during pre-assembly, captured inside the channels formed by the segments. This nested configuration protects the sealing element and eliminates the need for external manipulation, lubrication, and stretching during installation.
3Adaptability or versatility
If multiple piece parts are used in mechanical couplings, then the fitting can be adjusted and secured, but the installation process becomes complex and time-consuming
Solution Approach 1:
The invention merges multiple piece parts into a pre-assembled unit where the housing portions, sealing element, and connection members are combined before installation. While the individual components remain separate for manufacturing purposes, they are integrated into a single installable assembly, reducing the perceived complexity during installation.
Solution Approach 2:
The housing portions are pre-bolted together and the sealing element is pre-positioned during manufacturing, creating a partially assembled unit that maintains adjustability through the connection members while reducing the number of steps required during field installation.

Function Achieved in This Case
This solution reduces installation time and effort by allowing pipe elements to be inserted into preassembled fittings with split rings that deform to secure the joint, providing a more efficient and less messy process while maintaining mechanical integrity under pressure.

AI summary
A pipe fitting has housing portions attached in spaced relation to define non-coaxial receptacles that receive pipe elements. The housing portions are supported on split rings received within grooves in each housing portion. The housing portions are supported in spaced relation in a preassembled state to permit insertion of pipe elements into the receptacles without disassembly of the fitting. The grooves in the housing portions have a floor surface with three surface portions. Two of the surface portions on each groove of each housing portion engage the split rings when the housing portions are supported in spaced relation.
