Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Leakage issues in pipe coupling systems are prevalent, leading to inefficiencies and recurring problems in plumbing systems, particularly in under-sink drain systems, where leaks can account for up to 80% of issues, and existing solutions often require professional intervention or are not effective for DIY repairs.
Innovation Solution
A pipe coupling assembly featuring a socket with multiple sealing surfaces and a locking ring that compresses to form a liquid-tight seal, providing three points of contact to secure the pipe connection, ensuring a reliable and user-friendly sealing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional single-seal pipe coupling is used, then the device complexity is low, but the reliability of the seal is insufficient leading to leakage
Solution Approach 1:
The sealing mechanism is divided into multiple independent sealing surfaces (rim sealing surface, first socket sealing surface, and second socket sealing surface) that work together to provide redundant sealing. This segmentation allows each sealing surface to contribute to the overall seal reliability without requiring a completely complex integrated structure.
Solution Approach 2:
The locking ring is pre-configured with engagement features that automatically engage with the socket structure when the coupling is assembled. This preliminary positioning ensures that the sealing surfaces are properly aligned and compressed before the coupling is fully assembled, improving seal reliability without requiring complex adjustment mechanisms.
2Reliability
If a complex multi-component coupling system is used, then the seal reliability improves, but the ease of operation deteriorates requiring professional intervention
Solution Approach 1:
Multiple sealing functions are merged into a single integrated locking ring component that performs both sealing and locking functions simultaneously. This consolidation allows consumers to install the coupling using a simple single-component assembly process rather than coordinating multiple separate sealing components, improving ease of operation while maintaining reliable sealing.
Solution Approach 2:
The coupling design includes self-aligning and self-sealing features where the locking ring automatically positions itself to engage the sealing surfaces correctly during installation. This self-service mechanism eliminates the need for precise manual alignment or specialized tools, enabling consumers to perform DIY repairs successfully.
3Reliability
If traditional coupling methods are used, then the ease of manufacture is high, but the reliability of the connection is insufficient
Solution Approach 1:
The locking ring is designed as a universal component that simultaneously provides sealing, locking, and alignment functions. This multi-functionality allows a single standardized part to be manufactured using conventional processes while achieving reliable connections, rather than requiring multiple specialized components that would increase manufacturing complexity.
4Stability of the object's composition
If a locking mechanism with multiple engagement points is used, then the stability of the connection improves, but the device complexity increases
Solution Approach 1:
The locking ring features nested engagement structures where inner engagement features are positioned within or alongside outer engagement features. This nesting allows multiple engagement points to be achieved within a compact, simple-looking component structure, providing stable connection without apparent complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces leakage by creating multiple liquid-tight seals around the pipe end portion, enhancing the stability and sealing efficiency of the connection, making it easier for both professionals and consumers to achieve a secure and leak-free pipe coupling.
Implementation Method 1
rotation of the locking ring from the unlocked to the locked condition draws the flange toward the rim sealing surface. The flange compresses the rim sealing surface to form the liquid-tight seal around the first end portion
Implementation Method 2
The compressed rim sealing surface and the at least two socket sealing surfaces provide at least three liquid-tight seals around the first end portion of the first pipe

AI summary
A pipe coupling assembly for coupling a first end portion of a first pipe with a second pipe includes a socket formed on an end of the second pipe and a locking ring. The socket includes a rim defining an end opening through which at least a portion of the first end portion is inserted, the rim including a rim sealing surface adapted to form a liquid-tight seal around the first end portion. The socket also includes a sleeve portion having an exterior surface and an interior surface defining an interior space for receiving the first end portion, the interior surface comprising at least two socket sealing surfaces adapted to form a liquid-tight seal around the first end portion. The locking ring is adapted to cause the rim sealing surface to compress to form a liquid-tight seal around the first end portion.
