Sanitary Insert Unit with Elastic Flow Regulator and Tamperproof Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sanitary insert units with a jet regulator, attachment screen, and throughflow-quantity regulator face issues when installation parts are randomly combined, leading to a risk of dirt particles entering the throughflow-quantity regulator, resulting in poor performance and lower output capacity.
Innovation Solution
The solution involves a regulating body with connecting crosspieces that act as holding-down parts, ensuring the throughflow-quantity regulator is always installed with the jet regulator and attachment screen, forming a tamperproof seal, and using a holder with latching mechanisms to secure the parts together, preventing incorrect assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the installation parts (jet regulator, attachment screen, throughflow-quantity regulator) are provided separately with matching connectors for easy assembly, then the ease of operation is improved, but the reliability deteriorates due to random combination leading to dirt particles entering the throughflow-quantity regulator
Solution Approach 1:
The patent combines multiple installation parts (attachment screen, throughflow-quantity regulator, jet regulator) into a single integrated unit with a common housing. This merging ensures that all components are pre-assembled in the correct configuration, eliminating the risk of random combination while maintaining ease of installation as a single unit. The integrated design guarantees that the attachment screen is always positioned to protect the throughflow-quantity regulator from dirt particles.
2Ease of repair
If the installation parts are connected in a releasable manner for maintenance purposes, then the ease of repair is improved, but the reliability worsens due to potential incorrect reassembly
Solution Approach 1:
The patent segments the installation unit into distinct modular components (attachment screen, throughflow-quantity regulator, jet regulator) that can be independently removed and reinstalled. Each component has specific connection interfaces that ensure proper reassembly, maintaining reliability while enabling easy maintenance and repair operations.
3Adaptability or versatility
If the throughflow-quantity regulator is designed with a flow-restricting body made of elastic material to adjust water flow, then the adaptability is improved, but the device complexity increases due to the additional control mechanism
Solution Approach 1:
The patent uses an elastic flow-restricting body that changes its physical parameters (shape, volume, position) in response to water pressure and temperature variations. This automatic parameter adjustment provides adaptability to different water conditions without requiring complex external control mechanisms, valves, or actuators, thereby maintaining system simplicity while achieving versatile flow control.
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
This configuration ensures optimal functioning of the sanitary insert unit by ensuring correct assembly, preventing dirt particles from entering the throughflow-quantity regulator and maintaining performance, while allowing for easy and secure connection of the installation parts.
Implementation Method 1
the throughflow-quantity regulator has an annular flow-restricting body which is made of elastic material and encloses, between itself and a regulating profiling provided on a circumferential wall, a control gap which changes under the pressure of the water flowing through

AI summary
A sanitary insert unit having a jet regulator, an attachment screen arranged upstream of the jet regulator, and a throughflow-quantity regulator, provided between the jet regulator and attachment screen, having an elastic flow-restricting body that encloses, between itself and a regulating profiling provided on a circumferential wall, a water pressure changeable control gap. The throughflow-quantity regulator is releasably retained on the jet regulator and the attachment screen is releasably retained on the throughflow-quantity regulator. The regulating profiling is provided on the circumferential wall of a regulating body that is connected to a holder via at least one connecting crosspiece that acts as a holding-down part for the flow-restricting body, which is arranged between the connecting crosspiece and the jet regulator. The holder's inflow-side end periphery region is releasably fastened on the attachment screen and its outflow-side end periphery region is releasably fastened on the inner circumference of the regulator housing.
