Solution Overview

Problem

Existing cosmetic products face challenges such as difficulty in application, requirement of physical supports that need disposal, inadequate transport and release of active ingredients, and potential skin irritation from compounds functional for formulation structure rather than skin benefit.

Innovation Solution

A cosmetic patch product comprising a membrane substrate made of electrospun fibers, preferably nanofibers, using hyaluronic acid and an electrospinning promoter, which is completely absorbable by the skin and carries active ingredients like peptides, amino acids, or vitamins, without harmful compounds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional cosmetic products (creams, lotions, serums) are applied to the skin, then they provide functional compounds for skin treatment, but they require prolonged application time and prolonged massage for complete absorption, and leave cosmetic residues on fingers or applicators

Engineering Contradiction:
Improveactive ingredient deliveryVSAvoidapplication time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The invention uses a thin film support structure that delivers cosmetic active ingredients directly to the skin. The film format enables rapid transfer of ingredients without requiring prolonged massage or application time, while the entire film is absorbed or dissolved leaving no residue on fingers or applicators.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The invention changes the physical state and delivery parameters of cosmetic ingredients by incorporating them into a thin film matrix that dissolves or absorbs rapidly on skin contact. This parameter change transforms the application process from prolonged massage to immediate transfer, reducing application time significantly.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If fibrous physical supports are used to facilitate application of cosmetic products, then application ease is improved, but the support and packaging must be disposed of after use, creating waste

Engineering Contradiction:
Improveapplication easeVSAvoidwaste generation
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The invention employs a biodegradable thin film support that is designed to be temporarily disposable during application but environmentally benign. The film dissolves or absorbs completely after use, eliminating the need for disposal of non-biodegradable fibrous supports and reducing waste generation.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The thin film support possesses porous or mesh-like structure that facilitates rapid release and transfer of cosmetic ingredients to the skin while maintaining structural integrity during application. After use, the porous structure allows complete dissolution or absorption, preventing waste accumulation.

Inventive Principle:
Principle #31Porous materials

3Ease of operation

If known fibrous physical supports are used, then application is facilitated, but their specific surface does not allow suitable transport and release of active ingredients

Engineering Contradiction:
Improveapplication facilitationVSAvoidactive ingredient transport
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The thin film support provides an optimized surface area-to-volume ratio that enhances transport and release of active ingredients. The film structure allows intimate contact with the skin surface while maintaining sufficient surface area for ingredient loading and controlled release, overcoming the limitations of traditional fibrous supports.

Inventive Principle:
Principle #30Flexible shells and thin films

4Stability of the object's composition

If compounds functional for formulation structure (silicones, petrolatums, alcohols, preservatives) are added to cosmetic compositions, then formulation stability and consistency are improved, but they do not bring benefit to the skin and can cause drying, pore closure, allergies, or dermatitis

Engineering Contradiction:
Improveformulation stabilityVSAvoidskin irritation
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The invention extracts or eliminates harmful structural compounds (silicones, petrolatums, certain preservatives) from the cosmetic formulation by using a thin film delivery system that relies on the film matrix itself for structural integrity. This allows the cosmetic composition to be preservative-free or use only safe preservatives, and eliminates pore-clogging and skin-drying ingredients while maintaining formulation stability through the film structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention uses a composite thin film structure combining biodegradable polymer matrix with cosmetic active ingredients. This composite approach provides formulation stability through the film matrix rather than through harmful structural compounds, enabling the elimination of irritating ingredients while maintaining product integrity and stability.

Inventive Principle:
Principle #40Composite materials
