Jet Regulator Grid Network Aeration Swirl Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jet regulators face challenges in distributing incoming water flow effectively into individual jets without excessive swirling, which can interfere with air suction for aeration, leading to compromised functionality.
Innovation Solution
The jet regulator incorporates a grid network with criss-crossing grid bars where individual jets impinge nodal points, causing multi-axial jet fractionation, and includes deflector portions to prevent swirled water jets from reaching aeration openings, ensuring efficient distribution and aeration without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the jet fractionating device distributes incoming water flow into individual jets, then the water flow distribution is improved, but excessive swirling occurs which interferes with air suction for aeration
Solution Approach 1:
The jet fractionating device divides the incoming water flow into multiple individual jets through a perforated plate with multiple openings. This segmentation allows the water flow to be distributed effectively while reducing the intensity of swirling in each individual jet, thereby minimizing interference with air suction at the aeration openings.
Solution Approach 2:
The patent introduces an intermediary structure (the specific arrangement of the perforated plate and housing features) that mediates between the incoming water flow and the aeration openings. This intermediary design allows water to be fractionated into jets while preventing excessive swirling from reaching the air intake areas, thus protecting the aeration function.
2Productivity
If a grid network with criss-crossing grid bars is used for jet fractionation, then multi-axial jet fractionation occurs improving distribution, but device complexity increases
Solution Approach 1:
The grid network is segmented into criss-crossing grid bars that create multiple nodal points. This segmentation approach achieves multi-axial jet fractionation by directing individual jets through different orientations of bars, improving distribution effectiveness while maintaining a modular structure that can be manufactured relatively simply.
Solution Approach 2:
The grid network introduces an additional dimensional aspect to jet fractionation by using criss-crossing bars in multiple orientations. This multi-axial arrangement enhances the fractionation effect beyond what a single-direction grid could achieve, improving water distribution without requiring complex three-dimensional structures.
3Reliability
If deflector portions are added to prevent swirled water jets from reaching aeration openings, then aeration functionality is protected, but device complexity increases
Solution Approach 1:
Deflector portions are introduced as intermediary elements positioned between the jet fractionating device and the aeration openings. These deflectors intercept swirled water jets and redirect them away from the air intake areas, protecting the aeration functionality while maintaining a relatively simple structural addition rather than a complete system redesign.
4Stability of the object's composition
If the jet fractionating device is followed by a flow rectifier with stacked metal screens, then individual jets are recombined into a uniform stream, but manufacturing cost increases
Solution Approach 1:
The flow rectifier is constructed from multiple stacked metal screens, each with patterns of openings. This segmented approach allows the gradual recombination of individual jets into a uniform stream through multiple stages, achieving stable flow composition while using simple, manufacturable metal screen components that can be produced and assembled relatively easily.

Function Achieved in This Case
This design enhances the distribution and aeration of water jets by preventing excessive swirling and ensuring a uniform, bubbling jet formation, improving the overall performance and cost-effectiveness of the jet regulator.
Implementation Method 1
a jet fractionating device, which distributes the incoming water flow into a plurality of individual jets
Implementation Method 2
at least one of the individual jets formed in the jet fractionating device impinges a nodal point of individually crossing grid bars of a grid network arranged downstream. Due to the fact that at least some of the individual jets coming from the jet fractionating device impinge a nodal point formed by the criss-crossing grid bars another multi-axial jet fractionation of each individual jet occurs in this area.
Implementation Method 3
in the circumferential direction and at the interior housing circumference, in the flow direction downstream of the aeration openings, is provided with at least one deflector portion to keep the eddied water jets away from the aeration openings
Implementation Method 4
Through the aeration openings provided on the housing perimeter of the jet regulator housing, the air necessary for aerating the water jet can be suctioned in through the aeration openings provided at the housing perimeter of the jet regulator housing.
