Solution Overview

Problem

Dermatoporosis, a chronic skin condition leading to skin fragility and breakdown, is prevalent among the elderly and lacks effective treatments to reduce its effects.

Innovation Solution

A topical composition comprising Centella asiatica extract encapsulated within liposomes and alpha hydroxy acid (AHA), formulated as an emulsion with a pH of 4 to 5, which synergistically downregulates senescence-associated genes and upregulates cell cycle genes in mammalian skin cells.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional treatments are used for dermatoporosis, then skin fragility and breakdown are addressed, but effective treatment to reduce senescence and enhance fibroblast turnover is insufficient

Engineering Contradiction:

Improveeffectiveness of treatmentVSAvoidfibroblast turnover rate

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent combines multiple active ingredients (Centella asiatica extract, alpha hydroxy acid, and additional components) into a single topical composition formulation. This merging of ingredients allows synergistic effects to occur, where the combination produces greater effectiveness than individual components alone, thereby improving treatment reliability while enhancing fibroblast turnover rate.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention uses a composite topical composition containing multiple bioactive ingredients working together. The composite nature of the formulation enables simultaneous action on multiple pathways: anti-senescence, pro-fibroblast, and skin barrier reinforcement, thus addressing the treatment effectiveness gap while boosting productivity.

Inventive Principle:

Principle #40Composite materials

2Reliability

If topical compositions are applied to treat dermatoporosis, then skin health is improved, but the complexity of formulation and delivery systems increases

Engineering Contradiction:

Improveskin health improvementVSAvoidformulation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the complex formulation into distinct functional components: Centella asiatica extract for anti-senescence, alpha hydroxy acid for exfoliation and penetration enhancement, and additional ingredients for specific functions. This segmentation allows each component to be optimized independently while simplifying the overall formulation development and regulatory approval processes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention employs delivery system intermediaries such as liposomes or nanoparticles to facilitate the penetration of bioactive ingredients through the skin barrier. These intermediaries simplify the formulation by providing a controlled release mechanism and enhancing bioavailability, thereby reducing the complexity of achieving effective skin health improvement.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If the composition uses specific pH levels and concentrations, then efficacy is optimized, but manufacturing precision requirements increase

Engineering Contradiction:

Improvetreatment efficacyVSAvoidpH and concentration control

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent optimizes specific parameters including pH level (typically 3-5 for AHA stability and efficacy) and ingredient concentrations within defined ranges. By establishing these parameter ranges, the formulation achieves maximum efficacy while providing manufacturing flexibility. The parameters are set to balance effectiveness with manufacturability, avoiding overly stringent precision requirements.
