Push-Fit Spigot Coupling for Leak-Free Stub-Out Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing a spigot or faucet on a stub-out face challenges such as limited space for tool operation, difficulty in achieving a liquid-tight seal, and increased installation time due to adjustments in stub-out length, leading to issues like leaks and breakage.
Innovation Solution
A spigot configuration featuring a valve body, coupling member, and removal plate for a push-fit connection to the stub-out, allowing for easy installation and removal with a mounting flange and fasteners, and utilizing a release mechanism for disengagement, ensuring a liquid-tight seal without excess stub-out length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional installation methods are used to install a spigot on a stub-out, then a liquid-tight seal can be achieved, but the installation time increases and the process becomes complex due to limited space for tool operation and the need to adjust stub-out length
Solution Approach 1:
The invention divides the connection system into separate components: a spigot assembly with push-fit coupling and a stub-out connection. This segmentation allows the spigot to be installed independently using the push-fit mechanism, eliminating the need for complex tool operations in limited spaces and reducing installation time while maintaining seal integrity through the dedicated push-fit coupling design
Solution Approach 2:
The push-fit coupling acts as an intermediary mechanism between the spigot and the stub-out. This intermediary component provides a simplified connection interface that requires minimal space for operation and eliminates the need for traditional sealing procedures, thereby reducing installation time and complexity while ensuring a liquid-tight seal
2Ease of manufacture
If traditional installation methods are used with limited space, then connections can be made, but the operation becomes difficult and installation time increases due to limited space for tool operation
Solution Approach 1:
The invention extracts the complex tool operation requirements from the installation process by implementing a push-fit coupling mechanism. This allows the spigot to be installed through simple insertion and release ring actuation, eliminating the need for complex tools that would be difficult to operate in limited spaces, thereby improving both ease of installation and ease of operation
Solution Approach 2:
The push-fit coupling mechanism is designed to be self-installing through the release ring and collar interaction. The collar automatically engages with the stub-out when the release ring is actuated, eliminating the need for external tools or complex manual operations in limited spaces, thus improving ease of operation and installation
3Shape
If the stub-out length is adjusted to provide an acceptable finish, then a clean appearance can be achieved, but the installation process becomes more complex and time-consuming
Solution Approach 1:
The invention changes the critical parameter from stub-out length adjustment to push-fit coupling engagement. The push-fit mechanism accommodates the stub-out at the optimal length for aesthetic finish without requiring complex adjustment procedures, as the coupling design inherently provides the proper engagement depth, thereby maintaining clean appearance while reducing installation complexity
4Adaptability or versatility
If traditional connection methods are used, then spigots can be installed, but removal and reinstallation becomes difficult and time-consuming
Solution Approach 1:
The invention implements a dynamic connection system through the release ring and collar mechanism. The release ring can be actuated to move the collar, which automatically disengages the push-fit coupling, enabling easy removal. The same mechanism allows for quick reinstallation by simply inserting the spigot and actuating the release ring, thereby improving adaptability while significantly reducing the time required for removal and reinstallation operations

AI summary
A push-fit spigot. The spigot includes a push-fit coupling member removably disposed within an internal passage of a body of the spigot. The coupling member enables simple push-fit installation of the spigot on a stub-out in a structure. The coupling member is retained within the internal passage of the spigot by a removable fastener. A removal plate is installed on the stub-out prior to making insertion of the stub-out into the coupling member. Removal of the spigot from an installation on the stub-out is simply performed by removing the fastener between the coupling member and the body to enable removal of the body. The removal plate is then useable to depress a release collar in the coupling member to disengage the push-fit mechanism therein from the stub-out.
