Flat Jet Regulator Frictional Attachment Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary outlet fittings with non-circular water outlets face challenges in securely attaching flat jet regulators without visible fastening means, as traditional threads are not feasible and existing solutions restrict usability due to visible fasteners or excessive resistance.
Innovation Solution
A sanitary outlet fitting design where a flat jet regulator is positioned downstream of a cross-sectional enlargement in the flow guide, with a flow rate regulator or limiter upstream to manage water pressure, and a distribution surface with numerous flow holes followed by an impact surface and flow guide walls to create a homogeneous jet pattern, allowing for frictional attachment without additional fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a flat jet regulator is used in a non-circular water outlet, then the jet regulator can produce a flat band-shaped water jet, but the jet regulator cannot be attached with an external thread on the outer circumference
Solution Approach 1:
The jet regulator is divided into a flat plate-like body and a separate attachment component (flange or mounting structure). The flat plate produces the band-shaped jet while the separate attachment component provides the threaded connection interface, resolving the conflict between non-circular jet shape and threaded attachment requirement
Solution Approach 2:
The attachment interface is moved from the outer circumference (2D perimeter) to a separate dimensional plane, allowing the flat plate to maintain its non-circular shape for jet production while incorporating threading in a different spatial configuration that doesn't compromise the jet shape
2Ease of operation
If frictional attachment without threads is used, then the jet regulator can be easily attached and detached, but the attachment is not secure enough under high water pressure
Solution Approach 1:
The design merges frictional attachment (for ease of installation) with threaded fastening (for security under pressure) into a single integrated attachment mechanism. The threaded holes in the flange allow secure fastening while the overall design maintains simplicity and ease of operation
Solution Approach 2:
A flange or mounting bracket serves as an intermediary component between the jet regulator body and the water outlet. This intermediary provides the threaded attachment interface while allowing the main jet regulator body to remain a simple flat plate that is easy to attach and detach
3Reliability
If visible fastening means are used to secure the jet regulator, then the attachment is secure under pressure, but the fastening means appear disruptive to the appearance
Solution Approach 1:
The threaded attachment mechanism is extracted and integrated into the flange structure itself, allowing the fastening means to be concealed within the design rather than visible on the exterior. The flange's threaded holes provide secure attachment while remaining aesthetically acceptable
4Productivity
If a flow rate regulator is placed close to the jet regulator, then water pressure can be controlled, but the jet regulator experiences excessive resistance and requires stronger fastening
Solution Approach 1:
The flow control function is separated from the jet regulator body into a distinct flow rate regulator component positioned upstream. This segmentation allows the jet regulator to focus on jet production while the separate regulator handles pressure control, reducing the force requirements on the jet regulator's attachment

Function Achieved in This Case
This design reduces the effort required to secure the aerator, maintains a homogeneous and non-splashing jet pattern, and allows for easy detachment of the jet regulator without visible fastening means, even under high water pressure.

AI summary
The regulator (1) has a distributor surface comprising a set of through flow holes (4) for distributing water. The distributor surface and a deflector surface (5) are arranged in a central region of a beam cross section, and flow guidance walls (6) oriented in a flow direction are connected in series, where the regulator is provided directly downstream to a cross section extension of a flow guidance in the flow direction. The walls are arranged parallel to each other, and are connected by a central connecting wall (7), which run along a longitudinal axle of the guidance walls.
