Solution Overview

Problem

Current methods for developing skin care agents struggle to address the complex, multifactorial etiologies of skin conditions like acne, atopic dermatitis, dandruff, and psoriasis, due to the diffuse and low-level effects of cosmetic agents, which are not well-suited for connectivity mapping protocols designed for pharmaceutical agents.

Innovation Solution

The development of a method using gene expression signatures to evaluate the influence of perturbagens on skin homeostasis, enabling the identification of cosmetic agents effective across multiple skin conditions by constructing a connectivity map that accounts for diffuse and systemic effects of cosmetic agents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If connectivity mapping protocols designed for pharmaceutical agents are used to evaluate cosmetic agents, then the evaluation can leverage existing pharmacological databases and methods, but the diffuse and low-level effects of cosmetic agents cannot be adequately detected or measured

Engineering Contradiction:
Improveevaluation efficiencyVSAvoiddetection sensitivity
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent transforms the evaluation parameters from traditional pharmacological endpoints to gene expression-based metrics. By measuring changes in gene expression profiles rather than relying on conventional phenotypic assays, the method achieves sufficient sensitivity to detect the subtle, diffuse effects of cosmetic agents while maintaining high-throughput evaluation capabilities through standardized protocols.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces traditional mechanical/phenotypic observation methods with molecular-level gene expression analysis. Instead of measuring visible phenotypic changes or using complex mechanical assays, the method uses transcriptomic profiling to detect subtle biological effects, thereby achieving higher measurement precision for cosmetic agent evaluation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If traditional skin condition treatment methods are used, then each skin condition can be addressed with condition-specific therapies, but the complexity of multifactorial etiologies cannot be effectively managed and broad-spectrum treatments cannot be developed

Engineering Contradiction:
Improvetreatment specificityVSAvoidmethod complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal evaluation platform using gene expression signatures that can assess multiple skin conditions simultaneously. By identifying common transcriptional responses across different skin disorders (acne, atopic dermatitis, psoriasis, etc.), the method enables broad-spectrum cosmetic agents to be evaluated and developed for multiple indications, reducing overall complexity despite the multifactorial nature of skin conditions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent segments the complex evaluation process into distinct gene expression signature profiles for different skin conditions. By creating condition-specific transcriptional signatures that can be independently analyzed and compared, the method manages complexity through systematic categorization while maintaining the ability to identify cross-cutting therapeutic targets.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If gene expression signatures are used to evaluate cosmetic agents, then diffuse and systemic effects can be detected and measured, but the evaluation process becomes more complex and requires advanced data analysis

Engineering Contradiction:
Improveeffect detection capabilityVSAvoidevaluation system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces gene expression signatures as intermediary markers that translate subtle cosmetic agent effects into measurable transcriptional changes. These signatures act as mediators between the diffuse biological effects of cosmetic agents and detectable evaluation endpoints, enabling precise measurement while simplifying data interpretation through standardized signature profiles.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent performs preliminary characterization of gene expression signatures for multiple skin conditions before evaluating cosmetic agents. By pre-establishing condition-specific transcriptional profiles and normalization standards, the method reduces the complexity of real-time data analysis during agent evaluation, allowing researchers to focus on comparing test agent effects against established reference signatures.

Inventive Principle:
Principle #10Preliminary action
