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 inefficiencies and potential leaks.
Innovation Solution
A pipe coupling system featuring coupling segments with ring grooves and split ring connection rings that compress radially to securely join pipe elements, allowing for easier assembly and sealing without the need for extensive gasket stretching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional pipe coupling designs are used, then the joint can be sealed and pipe elements can be connected, but the installation process becomes difficult and time-consuming requiring disassembly and gasket stretching
Solution Approach 1:
The coupling device is divided into multiple coupling segments (e.g., first coupling segment, second coupling segment) that can be independently positioned and assembled. Each segment has its own fastening mechanism, allowing for simplified installation where segments are attached to pipe elements separately and then connected together, eliminating the need for complex disassembly and gasket stretching operations.
Solution Approach 2:
The coupling segments are designed with movable and adjustable components including fasteners, bearing members, and positioning mechanisms that allow dynamic adjustment during installation. This enables the coupling to adapt to different pipe configurations and facilitates easier assembly without requiring forceful gasket stretching or complex disassembly procedures.
2Reliability
If traditional pipe coupling designs are used, then the joint can be sealed, but the installation time increases due to multiple steps and potential leaks requiring rework
Solution Approach 1:
The coupling segments are pre-configured with sealing surfaces, bearing members, and fastening mechanisms in their proper positions before installation. This preliminary arrangement ensures that when the segments are assembled onto the pipe elements, the sealing is immediately effective without requiring multiple adjustment steps or rework, thereby reducing installation time while maintaining sealing reliability.
Solution Approach 2:
The coupling device incorporates self-aligning and self-sealing features where the bearing members and sealing surfaces automatically position themselves during assembly. The fastening mechanism includes self-locking elements that ensure proper tightness without requiring additional adjustment steps, enabling reliable sealing to be achieved quickly and efficiently during the installation process.
3Strength
If coupling segments with bearing members are used, then the legs can angle from axial ends to provide structural support, but the device complexity increases
Solution Approach 1:
The bearing member is integrated directly into the leg structure of the coupling segment, merging the support function with the structural framework. The leg extends from the coupling segment body and incorporates the bearing member as part of its structure, allowing it to angle from the axial end while providing both structural support and bearing functionality in a single unified component, thereby reducing overall device complexity.
Solution Approach 2:
The leg structure serves multiple functions simultaneously: it provides structural support, incorporates bearing members for rotational movement, and maintains the angled configuration from the axial end. This multi-functional design consolidates several components into one, reducing device complexity while maintaining the required structural strength and support capabilities.

AI summary
A pipe connection ring for a pipe coupling includes a ring body defining a first circumferential end and a second circumferential end opposite the first circumferential end; a first stepped portion extending from the first circumferential end of the ring body; and a second stepped portion extending from the second circumferential end of the ring body, the second stepped portion contacting and overlapping the first stepped portion in an uncompressed configuration; wherein the second stepped portion is unconnected to the first stepped portion and is configured to slide relative to the first stepped portion as the pipe connection ring is compressed.
