Interchangeable Socket Ring Sealing for Multi-Diameter Pipe Couplings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary systems require multiple siphon models and connection sections to accommodate varying pipe diameters, leading to increased stock requirements and complex installations.
Innovation Solution
A coupling assembly with a socket and interchangeable ring, featuring internal and external seals, allows for adaptation to different pipe diameters through a single piece ring design with bi-injected seals, ensuring easy installation and secure connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple siphon models and connection sections are used to accommodate varying pipe diameters, then adaptability to different pipe sizes is improved, but device complexity and stock requirements increase
Solution Approach 1:
The socket is designed with a universal structure that can accommodate multiple pipe diameters (32mm, 40mm, 50mm) through the interchangeable ring mechanism. The main socket body remains the same while different rings are attached to adapt to various pipe sizes, making the system multi-functional without requiring multiple complete siphon models
Solution Approach 2:
The connection assembly is segmented into distinct components: a main socket body and interchangeable rings. This segmentation allows the ring portion to be changed independently to match different pipe diameters, while the main socket structure remains constant, reducing the need to stock multiple complete assemblies
2Adaptability or versatility
If multiple connection sections are used to accommodate varying pipe diameters, then adaptability is improved, but the number of parts and installation steps increase
Solution Approach 1:
The ring and seal are merged into a single integrated component. The seal is molded directly onto the ring, eliminating the need for separate seal pieces and reducing the total number of parts. This integrated design simplifies the assembly while maintaining adaptability to different pipe sizes through ring interchangeability
3Reliability
If multiple connection sections with different seals are used for different pipe diameters, then sealing effectiveness is improved, but device complexity and stock requirements increase
Solution Approach 1:
The seal is designed with local quality variations through its dual-seal structure: an internal seal for sealing against the pipe and an external seal for sealing against the socket. Each seal is optimized for its specific sealing location, ensuring reliable sealing effectiveness while using a single integrated ring component rather than multiple different connection sections

Implementation Method 1
an internal seal for sealing between the ring and a pipe to be inserted, the internal seal having a lip which extends between an anchoring end on the second outer face and a seal free end
Implementation Method 2
an external seal provided in compression in the socket between the ring and the socket for sealing between the ring and the socket
