Solution Overview

Problem

Commercially available wet tissues often contain harsh chemicals that can irritate sensitive skin and are ineffective in removing bacteria, leading to consumer distrust and a need for environmentally friendly alternatives with proven safety and efficacy.

Innovation Solution

A wet tissue containing a hot-water extract or distillate of Coptidis rhizome, prepared by mixing 100 parts of Coptidis rhizoma with 2000-8000 parts of water under high temperature and high pressure conditions, which is then absorbed into a fabric and sterilized, providing antibacterial and anti-inflammatory properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If surfactants and chemical preservatives are added to wet tissue to enhance cleaning ability, then the ability to remove dirt is improved, but skin irritation and safety issues worsen

Engineering Contradiction:
Improvecleaning abilityVSAvoidskin irritation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes harmful chemical components (surfactants, chemical preservatives, fragrances, alcohols) from wet tissue formulation, retaining only water and herbal extracts. This extraction principle eliminates the source of skin irritation while maintaining cleaning functionality through natural herbal ingredients like Coptidis rhizoma extract which provides antibacterial and anti-inflammatory properties without chemical harm

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the chemical composition parameters of wet tissue by replacing synthetic chemicals with natural herbal extracts. Specifically, it uses Coptidis rhizoma extract containing berberine and other active compounds as alternatives to surfactants and chemical preservatives, fundamentally changing the ingredient profile from harmful chemicals to safe natural substances while maintaining or enhancing cleaning and antibacterial effects

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If conventional wet tissue products are used to wipe skin, then ease of use is improved, but effectiveness in removing bacteria deteriorates

Engineering Contradiction:
Improveease of useVSAvoidbacterial removal effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent merges multiple functions into a single wet tissue product: cleaning (via water and herbal extracts), antibacterial action (via Coptidis rhizoma extract containing berberine), and anti-inflammatory effects (via the same herbal extract). This combination allows the product to simultaneously perform wiping and bacterial removal without requiring separate products, maintaining ease of use while enhancing bacterial removal effectiveness through the synergistic effects of the herbal ingredients

Inventive Principle:
Principle #5Merging (Combining)

3Object-affected harmful factors

If environmentally friendly wet tissue products are produced without chemicals, then safety is improved, but proven efficacy deteriorates

Engineering Contradiction:
ImprovesafetyVSAvoidefficacy
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent employs Coptidis rhizoma extract which possesses inherent antibacterial and anti-inflammatory properties without requiring additional chemical additives. The herbal extract itself serves the dual function of both cleaning and protecting against bacteria, making the product both environmentally friendly and scientifically proven effective. The active compounds in the extract (berberine, palmatine, etc.) provide self-contained efficacy without external chemical support

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent changes the composition parameters to include specific concentrations of herbal extracts (Coptidis rhizoma extract at optimized levels) that have been scientifically validated for antibacterial and anti-inflammatory effects. This parameter optimization ensures that the chemical-free formulation maintains proven efficacy through precisely controlled amounts of active herbal ingredients rather than synthetic chemicals

Inventive Principle:
Principle #35Parameter changes
