Solution Overview

Problem

Current treatments for rosacea are often irritating to the skin, compromise efficacy due to the avoidance of irritating ingredients, and struggle to effectively address the complex symptoms of rosacea, especially when combined with acne vulgaris.

Innovation Solution

The use of antimicrobial peptide sequestering compounds, such as anionic chemicals and polymers, that bind cationic antimicrobial peptides like cathelicidins without inhibiting their formation or activity, reducing skin irritation and improving treatment efficacy for rosacea and other skin disorders.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional treatments for rosacea are applied, then some therapeutic effect is achieved, but skin irritation and discomfort increase

Engineering Contradiction:
Improvetreatment efficacyVSAvoidskin irritation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent identifies antimicrobial peptides (AMPs) as harmful factors causing rosacea symptoms, and converts this harm into benefit by using AMP-sequestering compounds to bind and neutralize the harmful AMPs. The sequestering compounds transform the pathological role of AMPs into a treatable target, allowing removal of the harmful effect while preserving beneficial skin functions.

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

Solution Approach 2:

The patent introduces AMP-sequestering compounds as intermediary substances that mediate between the harmful AMPs and the skin. These compounds act as mediators that bind to AMPs, preventing direct interaction between AMPs and skin cells, thereby reducing irritation while maintaining treatment efficacy.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If irritating ingredients are avoided in formulations, then skin irritation is reduced, but treatment efficacy is compromised

Engineering Contradiction:
Improveskin irritationVSAvoidtreatment efficacy
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent changes the fundamental parameter of treatment approach by targeting AMPs directly rather than using traditional anti-inflammatory or antibacterial agents. This parameter change allows for non-irritating formulations that achieve efficacy through a different mechanism - sequestering harmful AMPs rather than suppressing overall skin activity with potentially irritating substances.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If current rosacea treatments are used, then some symptoms are addressed, but acnegenic and comedogenic responses occur

Engineering Contradiction:
Improvesymptom managementVSAvoidacne formation
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful effect of AMP overproduction into a beneficial treatment target. By sequestering AMPs that cause both rosacea symptoms and acne formation, the treatment addresses multiple harmful effects simultaneously, preventing acne generation while managing rosacea symptoms.

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