Solution Overview

Problem

Existing sanitary fittings face issues where different liquids, such as mixed water, hot water, and carbonated water, mix within the aerator, leading to taste interference and hygiene concerns.

Innovation Solution

A jet regulator with at least three separate liquid channels ensures that different liquids, such as mixed water, hot water, and carbonated water, are directed through separate paths within the sanitary fitting, preventing them from mixing before exiting, thereby maintaining their taste integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a common aerator is used for multiple liquids, then device complexity is reduced, but liquids mix and affect each other's taste

Engineering Contradiction:

Improveaerator structureVSAvoidtaste interference

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The aerator is divided into multiple separate channels, with each channel dedicated to a specific liquid type. This segmentation prevents mixing between different liquids while maintaining a unified aerator component, thus resolving the contradiction between device simplicity and taste preservation.

Inventive Principle:

Principle #1Segmentation

2Ease of manufacture

If liquids flow through the same aerator areas, then manufacturing is simplified, but hygiene issues arise

Engineering Contradiction:

Improveaerator productionVSAvoidhygiene quality

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The aerator internal structure is segmented into separate flow channels for different liquids. This allows the aerator to be manufactured as a single component while ensuring that liquids do not mix, thereby maintaining both manufacturing simplicity and hygiene quality.

Inventive Principle:

Principle #1Segmentation

3Object-affected harmful factors

If separate liquid channels are implemented, then taste integrity is preserved, but device complexity increases

Engineering Contradiction:

Improvetaste interferenceVSAvoidjet regulator structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Multiple separate liquid channels are integrated into a single aerator component. This merging approach preserves taste integrity through channel separation while avoiding excessive device complexity by keeping the aerator as one unified part rather than multiple separate components.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If separate liquid channels are implemented, then hygiene is improved, but device complexity increases

Engineering Contradiction:

Improvehygiene qualityVSAvoidjet regulator structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The jet regulator integrates multiple separate liquid channels within a single aerator component. This design improves hygiene by preventing liquid mixing while avoiding excessive complexity by maintaining the aerator as one integrated part rather than multiple separate components.
