Sanitary Insert Unit Throughflow Regulator Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sanitary insert units with throughflow regulators face mounting issues due to construction height, particularly in retrofitting and environments with limited space, as they require a higher height than units with only jet regulators.
Innovation Solution
The throughflow regulator is arranged within the interior space below the upstream sieve, utilizing the previously unused space, and features a sloping surface with radial grooves to ensure water flow even with partial clogging, and is designed to fit within the existing height constraints, allowing for 100% geometrical compatibility and easy exchange or retrofitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a throughflow regulator is added to the insert unit, then water flow control and anti-clogging functionality are improved, but the construction height increases causing mounting problems
Solution Approach 1:
The throughflow regulator is nested within the interior space of the insert unit, specifically positioned below the upstream sieve and integrated into the existing structure. This nesting approach allows the throughflow regulator to be accommodated without significantly increasing the overall construction height, resolving the mounting problems while maintaining water flow control functionality
Solution Approach 2:
Instead of extending the throughflow regulator vertically (one dimension), the design utilizes the radial and axial dimensions within the existing cylindrical space. The throughflow regulator is arranged to fit within the interior space limited by the upstream sieve, effectively using three-dimensional space optimization to avoid height increase
2Length of stationary object
If the throughflow regulator is positioned to utilize interior space below the upstream sieve, then construction height is reduced, but space for water flow paths is limited
Solution Approach 1:
The interior space below the upstream sieve is segmented into functional zones: the throughflow regulator occupies the central region for flow control, while the sloping surface creates radial channels for water flow. This segmentation allows both compact positioning and adequate flow space within the limited volume
Solution Approach 2:
The sloping surface is designed with a curved, radially outward profile that efficiently utilizes the available cylindrical space. This curved geometry creates optimal flow paths from the periphery toward the center, maximizing water flow space while maintaining compact overall dimensions
3Reliability
If the upstream sieve becomes clogged, then water flow is blocked, but adding a throughflow regulator increases complexity
Solution Approach 1:
The throughflow regulator acts as an intermediary component between the upstream sieve and the downstream jet regulator. When the sieve clogs, the throughflow regulator provides an alternative flow path through its control gap, maintaining water flow continuity without requiring a completely redesigned complex system
Solution Approach 2:
The control gap of the throughflow regulator can be adjusted to change flow parameters. When the upstream sieve becomes clogged, the control gap can be enlarged to compensate for the reduced flow area, maintaining adequate water flow without increasing overall structural complexity

Function Achieved in This Case
This solution allows for seamless integration and functionality of sanitary insert units with throughflow regulators in limited spaces, maintaining water flow even with partial clogging, and preventing deformation of the upstream sieve, thus enhancing the stability and performance of the insert unit.
Implementation Method 1
inflowing water can be fed from the exterior region of the upstream sieve via the rising sloping surface to the throughflow regulator
Implementation Method 2
the rising sloping surface to be provided on its upper side with approximately radially aligned grooves to form individual inflow channels. Through the bundled water flow in the feeding channels, the inflow speed can be increased
Implementation Method 3
the bars located between the grooves to end close to or at the interior side of the upstream sieve and to serve as support elements for said upstream sieve. This way, the bars form supports for the upstream sieve so that the stability of the arrangement is improved and an undesired deformation of the upstream sieve, for example by excessive pressure of the inflowing water, can be avoided
Implementation Method 4
between the throttle body and the rising sloping surface a control gap is formed, with the cross-section of its opening being adjustable by the throttle body deforming under the pressure difference developing by the throughflow
