Solution Overview

Problem

Existing tea bags compromise tea quality and convenience due to the use of plastics and by-products, while molded tea compositions are inconvenient and lack pre-portioning and health benefits.

Innovation Solution

A molded tea composition using microbial cellulose, such as kombucha membrane, as a binder for dehydrated plant material, allowing for high sensory quality, convenience, and health benefits, with the ability to unfurl during brewing and being pre-portioned for single-serving use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If tea bags are made with plastics and by-products to provide convenience and structure, then ease of operation and manufacturing precision are improved, but object-generated harmful factors and quality deteriorate

Engineering Contradiction:
ImproveconvenienceVSAvoidplastics and chemicals
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent changes the material composition parameters by replacing synthetic plastics with natural plant-based materials like cornstarch and cellulose. This substitution maintains the structural integrity and convenience of tea bags while eliminating harmful plastic components, directly addressing the contradiction between ease of operation and harmful factors generated.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite materials made from natural polymers such as cornstarch, cellulose, and gelatin to create biodegradable tea bag structures. These composite materials provide the necessary mechanical strength and convenience for use while being environmentally friendly and free from harmful plastics, resolving the contradiction between operational convenience and harmful substance generation.

Inventive Principle:
Principle #40Composite materials

2Productivity

If tea bags use broken tealeaves and by-products to reduce cost, then productivity and manufacturing efficiency are improved, but quality and flavor complexity deteriorate

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidquality
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent changes the quality parameter by specifying the use of whole or large-fragment tealeaves instead of broken tealeaves and dust. This parameter change maintains manufacturing efficiency while significantly improving tea quality, flavor complexity, and brewing performance, directly resolving the contradiction between productivity and reliability.

Inventive Principle:
Principle #35Parameter changes

3Object-generated harmful factors

If molded tea compositions are made without binders to avoid chemicals, then object-generated harmful factors are reduced, but strength and structural integrity deteriorate

Engineering Contradiction:
ImprovechemicalsVSAvoidstructural integrity
Core Design Contradiction:
Object-generated harmful factorsVSStrength

Solution Approach 1:

The patent uses natural binders such as gelatin, pectin, and plant-based starches to create molded tea compositions. These natural binders provide the necessary structural integrity and binding strength while being chemically safe and free from harmful synthetic chemicals, resolving the contradiction between reducing harmful factors and maintaining structural strength.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes the binder composition parameters by replacing synthetic chemicals with natural polymers and biodegradable materials. This parameter substitution maintains the structural integrity required for molded tea forms while eliminating harmful chemical components, directly addressing the contradiction between strength and harmful factors.

Inventive Principle:
Principle #35Parameter changes

4Volume of moving object

If tealeaves are compressed tightly to create portable molded tea, then volume is reduced and convenience is improved, but the ability to unfurl and release flavor deteriorates

Engineering Contradiction:
ImproveportabilityVSAvoidflavor release
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The patent uses flexible, biodegradable wrapping materials made from plant-based polymers that can accommodate compressed tealeaves during storage but allow expansion during brewing. This flexible encapsulation maintains portability through compact form while enabling full unfurling and flavor release during the brewing process, resolving the contradiction between volume reduction and flavor release capability.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent creates a dynamic system where the molded tea composition transitions from a compact, tightly-bound state during storage to an expanded, unfurled state during brewing. The natural binders and plant-based materials allow this dynamic transformation, maintaining portability when compressed while enabling complete flavor release when water is added, directly addressing the contradiction between volume and flavor release.

Inventive Principle:
Principle #15Dynamics
