Solution Overview

Problem

Individuals with sensitive skin experience inflammation, redness, and discomfort, leading to chronic inflammation and a negative impact on mood and well-being, with existing treatments lacking effective solutions.

Innovation Solution

Application of a hydrophilic Phaeodactylum tricornutum extract in cosmetic compositions to soothe, comfort, and improve skin condition, reducing inflammation and rebalancing the skin microbiota through epigenetic regulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional skin care treatments are applied to sensitive skin, then skin barrier function is maintained, but inflammation and redness persist

Engineering Contradiction:

Improveinflammation and rednessVSAvoideffectiveness of treatment

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent applies epigenetic regulation to modify gene expression parameters in skin cells, specifically targeting inflammatory pathways. This changes the biological state of skin cells to reduce inflammation and redness while maintaining barrier function, representing a fundamental parameter change from conventional symptomatic treatment to molecular-level regulation.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The cosmetic composition acts as an intermediary substance that delivers epigenetic modulators to skin cells. This intermediary facilitates communication between the external environment and cellular processes, enabling anti-inflammatory effects without directly causing them, thus resolving the contradiction between treatment effectiveness and skin safety.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the skin microbiota is not rebalanced, then skin immunity remains compromised, but existing treatments do not effectively restore microbiota diversity

Engineering Contradiction:

Improvemicrobiota diversityVSAvoidsimplicity of treatment

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The cosmetic composition performs multiple functions simultaneously: it provides epigenetic regulation to reduce inflammation, rebalances microbiota diversity, and maintains skin barrier function. This multi-functionality resolves the contradiction by addressing microbiota restoration and immune compromise through a single unified treatment rather than multiple separate interventions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If chronic inflammation is not addressed, then skin defense system becomes exhausted, but conventional treatments only mask symptoms

Engineering Contradiction:

Improveskin defense system functionVSAvoidlong-term skin health

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent employs epigenetic regulation to preemptively restore skin defense mechanisms before complete exhaustion occurs. By modifying gene expression patterns related to inflammation and immunity, the treatment acts preliminarily to rebuild defense system capacity, preventing the cascade of biological reactions that lead to chronic inflammation and long-term damage.

Inventive Principle:

Principle #10Preliminary action
