Solution Overview

Problem

There is a need for effective, non-toxic, and cost-efficient agents with natural origins to reduce skin irritation and inflammation, particularly for sensitive skin, which current cosmetic and pharmaceutical agents fail to adequately address, especially in terms of stability, odor, and compatibility.

Innovation Solution

A medicament comprising an alcoholic extract of blackberry leaves, obtained by extracting blackberry leaves with a mixture of alcohols such as ethanol and water, which is decolorized and has a concentration range of 0.00001 to 20 wt.%, demonstrating enhanced skin irritation-reducing and anti-inflammatory properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional skin irritation-reducing agents are used, then skin irritation is reduced, but they fail to provide adequate stability, have unpleasant odor, or cause skin incompatibility

Engineering Contradiction:
ImprovestabilityVSAvoidodor and skin incompatibility
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the chemical parameters of the extract by using specific alcohol ratios (ethanol/water 3:7) and controlled extraction conditions (temperature 80-100°C, time 2 hours) to optimize the extract's stability, odor profile, and skin compatibility simultaneously

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent extracts only the beneficial components from blackberry leaves using alcohol extraction, separating the active ingredients (which provide skin irritation-reducing effects) from unwanted components (odor, instability), thereby achieving improved stability and reduced harmful factors

Inventive Principle:
Principle #2Taking out (Extraction)

2Object-generated harmful factors

If natural plant extracts are used to address sensitive skin, then skin compatibility improves, but effectiveness against inflammation is insufficient

Engineering Contradiction:
Improveskin compatibilityVSAvoidanti-inflammatory effectiveness
Core Design Contradiction:
Object-generated harmful factorsVSReliability

Solution Approach 1:

The patent creates a composite extract containing multiple active components from blackberry leaves (polyphenols, flavonoids, vitamins) that work synergistically to provide both skin compatibility and strong anti-inflammatory effectiveness, overcoming the limitation of single-component natural extracts

Inventive Principle:
Principle #40Composite materials

3Object-affected harmful factors

If current cosmetic agents are used for sensitive skin, then some irritation reduction is achieved, but they fail to adequately address interleukin release and inflammation

Engineering Contradiction:
Improveskin irritation reductionVSAvoidanti-inflammatory performance
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The blackberry leaf extract acts as an intermediary substance that mediates between the skin and inflammatory triggers, specifically inhibiting interleukin release while providing skin irritation reduction, thereby bridging the gap between symptom management and underlying inflammation treatment

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The blackberry leaf extract effectively reduces skin irritation and inflammation, inhibiting interleukin release while maintaining stability and minimal odor, making it suitable for cosmetic and pharmaceutical applications without altering the appearance or scent of formulations.

Implementation Method 1
