Solution Overview

Problem

Existing methods for manufacturing multi-layered drinks are time-consuming and complicated, resulting in unstable and intermingling layers due to insufficient density differences and the need for stabilizers like hydrocolloids, especially when dealing with similar density fruit juices and hot drinks.

Innovation Solution

A multi-layered drink with a density difference of 0.4 to 10 kg/m3 between layers, each containing at least one hydrocolloid, such as carboxymethylcellulose, to stabilize and separate the layers effectively, allowing for easy and quick manufacturing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If individual layers are carefully poured over a spoon to prevent intermingling, then layer separation is achieved, but the manufacturing process becomes time-consuming and complicated

Engineering Contradiction:
Improvelayer separationVSAvoidmanufacturing time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent changes the density parameter of the liquid layers to create a density difference of at least 0.1% between adjacent layers. This parameter change enables automatic layer separation based on density stratification, eliminating the need for careful pouring techniques and reducing manufacturing time while maintaining stable layer separation.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If density difference between layers is increased to maintain separation, then layer stability improves, but the range of suitable ingredients is limited and weighting agents are required

Engineering Contradiction:
Improvelayer stabilityVSAvoidingredient selection
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent adjusts the density parameter of drink concentrates by adding water to achieve the required density difference of at least 0.1%. This approach allows the use of various fruit juices and drink concentrates without requiring weighting agents like sugar, thereby maintaining ingredient versatility while ensuring layer stability.

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If slow addition of individual layers is used to reduce turbulences, then layer intermingling is reduced, but the manufacturing process becomes more time-consuming

Engineering Contradiction:
Improvelayer separationVSAvoidmanufacturing speed
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent creates a density difference of at least 0.1% between adjacent layers, which provides sufficient gravitational force to maintain layer separation even during faster pouring processes. This parameter change allows for increased manufacturing speed without compromising layer stability, as the density stratification naturally prevents turbulence-induced mixing.

Inventive Principle:
Principle #35Parameter changes

4Stability of the object's composition

If temperature gradient is applied to hot drinks to reduce diffusion, then layer stability improves, but the manufacturing process becomes more complicated

Engineering Contradiction:
Improvelayer stabilityVSAvoidtemperature control
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent primarily relies on density difference (at least 0.1%) as the stabilizing parameter for layer separation. While temperature gradient can be applied to hot drinks to further reduce diffusion, the patent indicates this is an additional measure rather than a requirement, thus avoiding mandatory temperature control complexity while maintaining layer stability through density stratification.

Inventive Principle:
Principle #35Parameter changes
