Push-Fit Piping Joint with Release Pusher for Reusable Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing piping systems face challenges in connecting different materials like copper, CPVC, and stainless steel, and lack the ability to repair or reuse fittings without damaging them, as they often require soldering, threading, or coining, which are labor-intensive and costly, and do not allow for the connection of unlike materials.
Innovation Solution
A push-fit piping joint assembly using a one-piece retaining ring and release pusher that creates a leak-free seal without tools, clamps, or glues, allowing for the connection of both like and unlike materials without coining or threading, and enabling the reuse of fittings by exposing the clamping and sealing mechanisms for easy removal and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional soldering or threading methods are used to connect piping, then the connection strength is improved, but the labor intensity and manufacturing cost increase significantly
Solution Approach 1:
The patent replaces traditional mechanical connection methods (soldering, threading, coining) with a push-fit mechanical system consisting of a fastening ring with gripping elements and a sealing ring. The fastening ring engages with the pipe through friction and mechanical interlocking, eliminating the need for thermal processes or complex machining operations.
Solution Approach 2:
The patent changes the connection mechanism from permanent (soldering/threading) to reversible by introducing a release pusher that can deform the fastening ring to release the pipe. This allows the connection to be made and broken repeatedly without damage, transforming the connection parameter from permanent to temporary/reusable.
2Ease of operation
If push-fit technology is used to simplify connection, then the ease of operation is improved, but the ability to repair and reuse fittings deteriorates
Solution Approach 1:
The patent introduces a dynamic release mechanism where the fastening ring can be deformed by the release pusher to transition from a gripping state to a releasing state. This allows the fitting to be easily disassembled and reused, transforming a static permanent connection into a dynamic reversible one.
Solution Approach 2:
The patent separates the fitting into distinct functional components: the body, the fastening ring, the sealing ring, and the release pusher. This segmentation allows individual components to be replaced or repaired independently, improving the overall reusability and ease of repair of the fitting system.
3Adaptability or versatility
If conventional fittings are used for connecting different materials, then the adaptability is limited, but the device complexity increases when attempting to connect unlike materials
Solution Approach 1:
The patent creates a universal fitting system where the same basic design can connect different pipe materials (copper, CPVC, stainless steel) by adjusting the gripping elements and sealing ring material. The fastening ring's flexible gripping mechanism adapts to different pipe surfaces, and the sealing ring material can be selected to match the pipe material, providing multi-material compatibility without increasing overall system complexity.
