Sanitary Outlet Flow Regulator with Dynamic Pressure Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary outlet elements fail to maintain an optimal flow cross-section at both low and high water pressures, leading to insufficient water flow through the jet regulator at low pressures, resulting in an uncomfortable water jet.
Innovation Solution
The flow rate regulator is designed to move from an open to a closed position, resting on a ring disk support, ensuring water flows only through the regulator, with an elastic throttle body that narrows the annular gap as pressure increases, maintaining a specified maximum flow rate regardless of pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the flow regulator is designed with a fixed flow rate regulation mechanism, then the maximum flow rate is controlled, but at low water pressures insufficient water flows through the regulator
Solution Approach 1:
The flow regulator transitions from a static fixed-flow design to a dynamic two-position system. The regulator can switch between an open position (allowing free flow at low pressures) and a closed regulation position (controlling flow at higher pressures), resolving the contradiction between maintaining sufficient flow at low pressure and regulating flow at high pressure
Solution Approach 2:
The system changes the flow regulation parameter dynamically based on pressure conditions. At low pressures, the regulator remains open with no flow restriction. When pressure exceeds a threshold, the regulator moves to the closed position, changing the flow parameter from unrestricted to regulated through the elastic throttle body's pressure-dependent gap narrowing
2Productivity
If the regulator housing is surrounded by water in the open position, then water can flow freely, but water may leak through the support opening
Solution Approach 1:
The harmful leakage path through the support opening is eliminated by closing it when the regulator moves to the closed position. The support opening, which would allow unwanted leakage, is effectively removed from the flow path by the regulator housing sealing against the support structure in the closed position
Solution Approach 2:
The support opening's state changes dynamically with regulator position. In the open position, the support opening is accessible for structural support. In the closed position, the regulator housing seals against the support, closing the opening and preventing leakage, thus adapting the system to different operational requirements
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 design ensures reliable and adjustable operation, preventing leakage and maintaining a consistent water flow, even at low pressures, by using a restoring element to adjust the regulator's position and a ring seal for tight closure, effectively regulating water flow to a specified value.
Implementation Method 1
an annular throttle body (7) made of elastic material, which is arranged in an annular groove (8) in the regulator housing (5) and surrounds a housing core (10). At least one of the circumferential walls bounding the annular groove (8) has a control profile (11) into which the elastic throttle body (7) increasingly conforms as the pressure of the flowing water increases
Implementation Method 2
the flow regulator (4), with its regulator housing (5), can be moved from a closed position, in which the water flowing through the insertion housing (2) of the outlet element (1) to the aerator (3) can only flow through the flow regulator (4), against the restoring force of at least one restoring element (6) into an open position

AI summary
The invention relates to a sanitary outlet element (1) which, with its insertion housing (2), can be inserted into the water outlet of a sanitary outlet fitting and has a jet regulator (3) for shaping the emerging water jet, to which a flow rate regulator (4) or a flow throttle is connected upstream on the inflow side, which regulates or limits the amount of water flowing through per unit of time to a fixed value.The outlet element according to the invention is characterized in that the flow rate regulator (4) or the flow restrictor with its throttle or regulator housing (5) is slidably guided in the insertion housing (2) and can be moved from an open position, in which the throttle or regulator housing (5) is at least partially surrounded by water, against the restoring force of at least one restoring element (6) to a closed position, in which the water flowing to the aerator (3) flows through the flow rate regulator (4) or the flow restrictor (see Fig. 3).
