Solution Overview

Problem

Existing tea-based beverages often rely on dairy products for creaminess and emulsion stability, which may not be suitable for non-dairy consumers and can be inconvenient for ready-to-drink formats.

Innovation Solution

A tea-based beverage composition using gelatinized starch and plant protein from lentil or pea flour, providing a creamy mouthfeel and emulsion stability without dairy, suitable for both ready-to-drink and reconstitutable forms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dairy products are used to provide creaminess and emulsion stability in tea-based beverages, then the beverage achieves a creamy mouthfeel and stable emulsion, but the beverage becomes unsuitable for non-dairy consumers and less convenient for ready-to-drink formats

Engineering Contradiction:
Improveemulsion stabilityVSAvoidsuitability for non-dairy consumers
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent changes the chemical composition parameters by replacing dairy proteins and fats with plant-based alternatives (pea protein, lentil protein, sunflower oil, rice bran oil). This substitution maintains the functional properties of creaminess and emulsion stability while making the beverage suitable for non-dairy consumers. The specific parameter changes include using 0.1-10% plant protein and 2-35% oil in the beverage composition.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite material system combining multiple plant-based ingredients (gelatinized starch, plant protein, oil, saccharide) to replicate the functional properties of dairy-based creamers. This composite approach using plant-derived components achieves both emulsion stability and adaptability to non-dairy dietary requirements.

Inventive Principle:
Principle #40Composite materials

2Stability of the object's composition

If dairy-based creamers are used in tea beverages, then a creamy texture is achieved, but the beverage becomes less suitable for ready-to-drink formats and requires refrigeration

Engineering Contradiction:
ImprovecreaminessVSAvoidconvenience for ready-to-drink format
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent changes the physical and chemical parameters by using plant-based oils and proteins that remain stable at ambient temperature, eliminating the need for refrigeration. The beverage can be stored and distributed in ready-to-drink formats without requiring cold chain logistics, while maintaining creamy texture through the plant-based composition.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs shelf-stable plant-based ingredients that do not require refrigeration, enabling the beverage to be produced, distributed, and consumed in convenient ready-to-drink formats. This approach eliminates the need for complex refrigeration infrastructure and makes the beverage more accessible for on-the-go consumption.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Adaptability or versatility

If plant protein and gelatinized starch are used instead of dairy products, then the beverage becomes suitable for non-dairy consumers and easier to store, but achieving the same emulsion stability and creamy mouthfeel becomes more difficult

Engineering Contradiction:
Improvesuitability for non-dairy consumersVSAvoidemulsion stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines multiple plant-based ingredients (gelatinized starch, plant protein, and oil) in specific proportions to create a composite system that achieves emulsion stability comparable to dairy-based formulations. The synergistic interaction between these plant-derived components compensates for the absence of dairy proteins and fats, maintaining reliable emulsion stability.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent optimizes the concentration parameters of plant-based ingredients to achieve desired functional properties. By adjusting the amounts of plant protein (0.1-10%), oil (2-35%), and gelatinized starch, the formulation achieves both adaptability to non-dairy diets and reliable emulsion stability, resolving the apparent contradiction between these two requirements.

Inventive Principle:
Principle #35Parameter changes
