Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sanitary installation elements in water lines, such as jet regulators, often fail to maintain optimal water flow at low pressures, leading to unpleasant water jets due to flow resistance and insufficient water quantity.
Innovation Solution
Incorporating an admixing device with a throttling or closing element that moves under water pressure to adjust the throughflow cross section, providing a larger cross section at low pressures and reducing it at high pressures, ensuring consistent water flow and jet quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a jet splitter and downstream functional units are provided to form a homogeneous water jet, then jet quality is improved, but flow resistance increases and water quantity becomes insufficient at low pressures
Solution Approach 1:
The patent employs a movable closing element that dynamically adjusts the throughflow cross-section based on water pressure. At low pressures, the element remains retracted to maximize flow area and ensure sufficient water quantity. At high pressures, the element moves into a throttling position to reduce flow area and prevent excessive flow, thereby maintaining optimal jet quality across varying pressure conditions.
Solution Approach 2:
The invention changes the flow resistance parameter adaptively by using a closing element that responds to pressure changes. The element transitions between different positional states (retracted at low pressure, throttling at high pressure), thereby dynamically adjusting the throughflow cross-section to maintain optimal water quantity and jet quality across the entire pressure range.
2Quantity of substance
If the throughflow cross section is kept large to ensure sufficient water quantity at low pressures, then water quantity is improved, but jet quality deteriorates at high pressures due to excessive flow
Solution Approach 1:
The closing element dynamically adjusts its position based on instantaneous water pressure conditions. At low pressures, it remains retracted to maintain a large throughflow cross-section for sufficient water quantity. At high pressures, it automatically moves to a throttling position to reduce the cross-section and optimize jet quality, eliminating the need for manual adjustment.
Solution Approach 2:
The system is self-regulating through the pressure-responsive closing element that automatically adjusts the flow characteristics based on the operating conditions. The element responds inherently to pressure changes without external control, maintaining optimal water quantity and jet quality across varying pressure ranges through its own mechanical response.
3Manufacturing precision
If a throttling element is introduced to control flow at high pressures, then jet quality is maintained, but device complexity increases
Solution Approach 1:
The closing element operates autonomously by responding directly to water pressure changes. It moves into the throttling position when pressure increases and returns when pressure decreases, eliminating the need for external actuators, sensors, or control systems. This self-regulating mechanism adds minimal structural complexity while effectively maintaining jet quality across pressure ranges.
Solution Approach 2:
The invention uses the water pressure itself as the actuating force for the closing element. The hydraulic pressure directly drives the element's movement between retracted and throttling positions, eliminating the need for separate mechanical actuation systems and keeping the device structure simple while achieving effective flow control.

Function Achieved in This Case
This solution ensures a consistent and comfortable water jet across a wide pressure range by optimizing the throughflow curve, allowing sufficient water quantity to flow through the jet regulator even at low pressures, maintaining a pleasant and homogeneous jet.
Implementation Method 1
the sanitary installation element has an admixing device with at least one throttling or closing element which can move, under the pressure of the inflowing water

AI summary
A sanitary insert, which is arranged in a water line, is provided. The sanitary insert includes a mixing device with at least one throttling or closing element, which can be moved under the pressure of the inflowing water from a mixing or open position into a throttling or closed position against a restoring force. The mixing device offers a relatively large clear flow cross section when the at least one throttling or closing element in the mixing or open position, and, by contrast thereto, a reduced clear flow cross section when the at least one throttling or closing element is in the throttling or closed position. The installation element always offers an optimum flow cross section both in low and high pressure ranges.
