Solution Overview

Problem

Existing beverage dispensing machines suffer from syrup contamination between different dispensed beverages, leading to unpredictable flavor variations, and lack efficient cleaning mechanisms for internal parts.

Innovation Solution

A diffuser with a unique design featuring cascading passages and peripheral outlets that separate the flow of base liquid and syrup, ensuring minimal contamination and automatic cleaning through the base liquid's peripheral flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If syrups pass through the same passage in the nozzle, then the machine structure is simplified and compact, but syrup contamination occurs between different beverage dispensings

Engineering Contradiction:
Improvenozzle structureVSAvoidbeverage flavor consistency
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The diffuser divides the single syrup passage into multiple separate passages (first peripheral passage, second peripheral passage, third peripheral passage) that are spatially separated. Each passage handles a different syrup type, preventing cross-contamination while maintaining a compact overall structure. The segmentation of flow paths is the core solution to the contradiction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a single-dimensional (single passage) to multi-dimensional (multiple spatially separated passages) syrup flow configuration. By arranging passages in different spatial dimensions and orientations, the design prevents syrup mixing while keeping the nozzle compact, resolving the contradiction between structural simplicity and flavor consistency.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If a single nozzle is used for different beverage types, then the machine is more versatile, but cleaning between dispensings becomes difficult

Engineering Contradiction:
Improvebeverage type flexibilityVSAvoidnozzle cleaning accessibility
Core Design Contradiction:
Adaptability or versatilityVSEase of repair

Solution Approach 1:

The diffuser segments the internal structure into multiple accessible passages (first, second, and third peripheral passages) that can be individually cleaned. The separation of syrup paths allows cleaning tools to access each passage independently, making maintenance easier while maintaining versatility for different beverage types.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The diffuser design extracts and separates the cleaning function from the dispensing function by creating passages that are accessible for cleaning while maintaining the integrated nozzle structure for versatile beverage dispensing. The peripheral passages are positioned to allow external cleaning access.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If syrups flow through the same channel, then manufacturing is simpler, but flavor contamination occurs between different drinks

Engineering Contradiction:
Improvenozzle fabricationVSAvoidsyrup flavor contamination
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The diffuser segments the syrup flow into multiple distinct passages (first peripheral passage with first opening, second peripheral passage with second opening, third peripheral passage with third opening) that are manufactured as separate but integrated channels. This segmentation prevents flavor contamination while maintaining manufacturing efficiency through integrated diffuser construction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each peripheral passage is designed with specific local characteristics (different orientations, positions, and opening locations) that optimize its function while preventing cross-contamination. The local quality variations in passage geometry and positioning enable both manufacturing efficiency and contamination prevention.

Inventive Principle:
Principle #3Local quality

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 diffuser effectively prevents syrup contamination and ensures consistent flavor by minimizing residual syrup in the system, while maintaining carbonation levels and facilitating automatic cleaning.
