Solution Overview

Problem

Current treatments for non-allergic irritant contact dermatitis are inadequate, as they often cause skin irritation when used in excess, and there is a lack of effective agents to prevent and treat this condition effectively.

Innovation Solution

The use of Lactobacillus paracasei or its fractions and metabolites as a probiotic microorganism in cosmetic or dermatological compositions to regulate skin irritation, specifically by selectively stimulating the production of the regulatory cytokine IL-8.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional treatments are used to treat non-allergic irritant contact dermatitis, then skin irritation is addressed, but the treatments cause additional skin irritation when used in excess

Engineering Contradiction:
Improveeffectiveness of treatmentVSAvoidskin irritation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The probiotic microorganism acts as an intermediary agent that modulates the skin's immune response to irritants. It doesn't directly neutralize the irritant but rather enhances the skin's natural defense mechanisms by stimulating regulatory cytokine production, thereby reducing the harmful inflammatory response without causing additional irritation

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention converts the concept of using antimicrobial agents (which can be irritating) into using probiotic microorganisms that benefit the skin. The probiotic microorganism transforms the approach from directly combating irritants to enhancing the skin's own protective and regulatory mechanisms, turning a potentially harmful treatment approach into a beneficial one

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Object-affected harmful factors

If current treatments are applied to prevent skin irritation, then some protection is provided, but they lack effectiveness and can cause irritation when overused

Engineering Contradiction:
Improveskin irritation preventionVSAvoideffectiveness of prevention
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The probiotic microorganism is applied in advance to establish a protective effect before irritant exposure. It primed the skin's immune system by stimulating regulatory cytokine production ahead of time, creating a state of enhanced protection that reduces the impact of subsequent irritant exposure without requiring repeated applications

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the skin barrier is exposed to external attacks, then the skin performs its barrier function, but the quality of the skin barrier is degraded over time

Engineering Contradiction:
Improvebarrier functionVSAvoidskin barrier quality
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The probiotic microorganism enables the skin barrier to serve itself by stimulating the production of regulatory cytokines that enhance the skin's own protective mechanisms. Rather than providing external protection that degrades the barrier, the treatment empowers the skin to maintain and strengthen its own barrier function through enhanced immune regulation

Inventive Principle:
Principle #25Self-service
