Sanitary Water Conduit Fitting Jet Regulator Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water pipe fittings with jet regulators face manufacturing complexity due to the need for precise screw holes and additional components, making assembly cumbersome.
Innovation Solution
Integration of a molded seal with dual functionality for sealing and fastening, utilizing a shoulder and groove design within the fitting body, where axial pressure from connecting screws secures the jet regulator, eliminating the need for additional fastening means on the fitting body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw holes are provided in the cast body for fastening the jet regulator, then the jet regulator can be securely fastened, but the manufacturing complexity and assembly difficulty increase significantly
Solution Approach 1:
The patent merges the sealing function and fastening function into a single molded seal component. The molded seal simultaneously seals the jet regulator to the fitting body and provides fastening through radial expansion into the groove, eliminating the need for separate fastening means and reducing assembly complexity
Solution Approach 2:
The molded seal performs multiple functions: it seals the jet regulator against the fitting body, provides axial abutment for the fastening plate, and secures the assembly through radial expansion into the groove. This multi-functionality reduces the number of components needed
2Reliability
If an intermediate holder is used to receive the jet regulator, then the jet regulator can be securely mounted, but additional components must be manufactured and stored, increasing device complexity
Solution Approach 1:
The patent eliminates the intermediate holder by integrating the fastening function directly into the molded seal and fitting body groove. The molded seal expands radially into the groove to provide both sealing and fastening, removing the need for separate intermediate holding components
Solution Approach 2:
The patent extracts and eliminates the intermediate holder component from the assembly. The fitting body groove directly receives the molded seal, which in turn secures the jet regulator, simplifying the component structure while maintaining mounting security
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
Simplifies the assembly process by using a single component for both sealing and fastening, reducing manufacturing complexity and allowing easy replacement of the molded seal, while ensuring secure attachment of the jet regulator.
Implementation Method 1
when the appropriate axial pressure is exerted, the molded seal expands radially into the groove provided for this purpose in the fitting body and digs into the groove

AI summary
A water conduit fitting with a water outlet and a jet regulator inserted therein and connected to the fitting body is characterized in that, to secure the jet regulator (18) in the water outlet (11), a fastening plate (14) and a moulded seal (16) arranged, between the jet regulator (18) and the fastening plate (14) and expanding radially when pressure acts axially, can be inserted into the water outlet (11) in addition to the jet regulator (18), and in that the fitting body (10), in the region of the water outlet (11), has on the inside a step (12) as a stop for the inserted fastening plate (14) and a groove (13) for accommodating an outer section of the moulded seal (16) expanding radially when pressure acts axially.
