Solution Overview

Problem

Conventional tea-based beverages are inconvenient to prepare and often require high consumption rates to achieve health benefits from catechins, as they involve slow infusion and dissolution of tea leaves or powders, making it difficult for individuals to meet daily intake requirements.

Innovation Solution

A beverage precursor comprising green tea leaf and/or stem, packaged in a specific amount and composition, designed to produce a tea-based beverage with a catechin content of 0.05-2% by weight when contacted with water at 90°C for 2 minutes, optimized for efficient catechin delivery and convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional tea leaves or powders are used as beverage precursors, then the beverage can be prepared, but the infusion and dissolution process is slow, requiring high consumption rates to achieve health benefits

Engineering Contradiction:
Improvecatechin delivery efficiencyVSAvoidpreparation time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent changes the physical and chemical parameters of the tea material by using ultra-fine particles (average diameter 1-10 μm) and specific surface area (50-500 m²/g), which dramatically increases the dissolution rate and catechin delivery efficiency, reducing preparation time while maintaining health benefits

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The tea material is segmented into ultra-fine particles through advanced grinding and classification processes, creating uniformly sized micro-particles that dissolve rapidly in water, thereby improving both preparation speed and catechin extraction efficiency

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If conventional beverage precursors are used, then preparation is possible, but the process is inconvenient for everyday use due to slow infusion and dissolution rates

Engineering Contradiction:
Improveconvenience of preparationVSAvoiddissolution rate
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

By transforming the tea material into ultra-fine particles with controlled size distribution and high surface area, the patent makes the beverage precursor extremely easy to prepare - simply adding to water produces rapid dissolution, greatly improving ease of operation for everyday use

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If high consumption rates of conventional tea beverages are maintained, then health benefits from catechins can be achieved, but this is difficult to sustain long term

Engineering Contradiction:
Improvecatechin intakeVSAvoidlong term consumption sustainability
Core Design Contradiction:
Quantity of substanceVSDuration of action of moving object

Solution Approach 1:

The ultra-fine particle formulation increases catechin delivery efficiency per serving, allowing consumers to achieve the same daily catechin intake with fewer beverages, making long-term sustainable consumption much more achievable

Inventive Principle:
Principle #35Parameter changes
