Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary inserts experience pressure drops and undesirable steam generation when handling superheated liquids like boiling water, leading to uneven flow and jerky operation.
Innovation Solution
A sanitary insert with an inner water channel featuring a flow obstruction that generates both laterally and forward-directed outlet openings, combined with a mixing chamber and ventilation features to manage flow and prevent pressure drops, ensuring uniform jet patterns and reduced steam formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple water channel structure is used, then the device complexity is reduced, but pressure drops and steam generation occur when handling superheated liquids
Solution Approach 1:
The flow obstruction is positioned upstream in the inner water channel to pre-deflect the flow before it reaches the outlet. This preliminary action prevents excessive velocity and pressure build-up that would cause steam generation, while the gradual deflection through laterally directed outlets maintains flow stability without requiring complex downstream structures.
Solution Approach 2:
The flow obstruction divides the single inner water channel flow into multiple streams through laterally directed outlet openings. This segmentation reduces the velocity and pressure of each individual flow stream, preventing steam generation while maintaining overall flow stability. The segmented flows then merge in the mixing chamber to form a stable combined jet.
2Stability of the object's composition
If the inner water channel flow is directly discharged, then the jet width is narrow, but it does not match the outer water channel flow width
Solution Approach 1:
The flow obstruction incorporates laterally directed outlet openings that deflect the inner channel flow in the radial direction, perpendicular to the original axial flow direction. This dimensional change expands the flow width to match the outer channel flow width, creating uniform jet patterns without requiring complex widening structures.
Solution Approach 2:
The flow obstruction acts as an intermediary element between the inner and outer water channels. It receives the narrow inner channel flow, redistributes it laterally through its outlet openings, and releases it at a width that matches the outer channel flow, enabling uniform combined jet patterns.
3Ease of operation
If forward-facing outlet openings are added to the flow obstruction, then axial flow is maintained, but the device complexity increases
Solution Approach 1:
The flow obstruction is designed with dual-function outlet openings: laterally directed outlets for radial flow expansion and forward-facing outlets for axial flow maintenance. This multi-functionality allows a single component to control both the width and direction of the inner channel flow, providing flexible flow control without requiring multiple separate devices.
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
The solution stabilizes flow and prevents excessive pressure drops, enabling smooth operation with superheated liquids and uniform jet patterns, while allowing for effective mixing and aeration.
Implementation Method 1
a flow obstruction is formed in the inner water channel, which at least partially generates a laterally directed flow, in particular a radial flow
Implementation Method 2
The formation of a flow obstruction can also prevent a pressure drop upstream of the insert due to backflow from becoming too great
Implementation Method 3
a mixing chamber can be provided downstream of the flow obstruction, in which the outer and inner water flows are combined
Implementation Method 4
a baffle plate can be arranged downstream of the flow obstruction. This allows the water to be calmed
Implementation Method 5
at least one acceleration nozzle can be provided in the outer water channel at the inlet to the mixing chamber. This allows an aerated jet to be generated in the outer water channel
