Solution Overview

Problem

Traditional tea manufacturing methods limit the customization of tea products' physico-chemical properties, flavor, and aroma, failing to meet consumer demands for enhanced infusion speed, color, and aroma, and restricting the choice of tea varieties and agronomy.

Innovation Solution

Combining tea juice expressed from fresh tea leaves with made tea, allowing for the manipulation of the tea's composition to achieve desired properties, such as increased water-soluble tea solids and unique flavor profiles without excessive bitterness, by blending the juice with leaf tea or tea solids.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional tea manufacturing methods are used, then the manufacturing process is simple and well-established, but the physico-chemical properties of the tea product cannot be customized to meet consumer requirements

Engineering Contradiction:
Improvecustomization of physico-chemical propertiesVSAvoidmanufacturing process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The tea manufacturing process is segmented into distinct stages: fresh leaf processing to extract juice, separate processing of leaf material, and final combination. This segmentation allows independent optimization of each component's properties before integration, enabling customization of physico-chemical characteristics without overwhelming complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies preliminary action by extracting and preserving tea juice from fresh leaves before the leaves are fully processed into made tea. This preliminary extraction allows the juice to be stored and combined later with made tea, enabling flexible customization of product properties while maintaining a relatively simple overall manufacturing process.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If tea juice is combined with made tea, then the infusion speed and consumer liking are improved, but the manufacturing process becomes more complex

Engineering Contradiction:
Improveinfusion speedVSAvoidmanufacturing process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Tea juice serves as an intermediary substance that bridges fresh leaf properties and made tea properties. By combining juice extracted from fresh leaves with made tea, the patent creates a product that exhibits enhanced infusion speed and consumer liking without requiring complete redesign of the manufacturing process.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent utilizes parameter changes by adjusting the ratio and concentration of tea juice to made tea in the final product. This allows optimization of infusion speed and flavor characteristics through simple compositional adjustment rather than complex process modification.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If tea juice is combined with made tea, then the flavor profile and aroma are enhanced, but bitterness and negative attributes may increase

Engineering Contradiction:
Improveflavor profile customizationVSAvoidbitterness
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by selectively combining tea juice with made tea in specific proportions to achieve desired flavor characteristics. Different regions or batches of juice can be combined with made tea in varying ratios to localize specific flavor properties while minimizing bitterness, allowing precise control over the final product's taste profile.

Inventive Principle:
Principle #3Local quality
