Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing textile fibers with cosmetic active ingredients suffer from low effectiveness and durability as these ingredients are only surface-bound and gradually released, leading to inadequate hydrating, antioxidant, or firming properties.

Innovation Solution

Development of polyamide-based textile fibers with hyaluronic acid-conjugated gold and polyethylene glycol-conjugated platinum nanoparticles homogeneously distributed throughout the fiber, which are synthesized and incorporated during the fiber manufacturing process to ensure deep skin penetration and prolonged release of these nanoparticles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If cosmetic active ingredients are added to the fiber surface after manufacturing, then the fiber can be produced using conventional methods, but the effectiveness and durability of the cosmetic effect are low

Engineering Contradiction:

Improveease of manufactureVSAvoideffectiveness and durability of cosmetic effect

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent incorporates cosmetic active ingredients into the fiber structure during the manufacturing process itself, rather than adding them afterward. The active ingredients are integrated into the polymer matrix before fiber formation, ensuring they are permanently embedded and released gradually over time, which dramatically improves both effectiveness and durability while maintaining conventional manufacturing compatibility

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent creates a composite fiber structure where cosmetic active ingredients are combined with the polymer matrix at the molecular level. This composite approach allows the active ingredients to be uniformly distributed and firmly embedded within the fiber, enabling sustained release and prolonged cosmetic effect while preserving the mechanical properties of the original fiber

Inventive Principle:

Principle #40Composite materials

2Device complexity

If cosmetic active ingredients are bound only to the surface of the fiber, then the manufacturing process remains simple, but the ingredients are gradually released and provide inadequate cosmetic properties

Engineering Contradiction:

Improvecomplexity of ingredient incorporationVSAvoidduration of cosmetic effect

Core Design Contradiction:

Device complexityVSDuration of action of moving object

Solution Approach 1:

The patent embeds cosmetic active ingredients within the internal structure of the fiber, nesting them deep within the polymer matrix rather than merely coating the surface. This nested configuration allows the ingredients to be protected within the fiber core and released gradually through controlled diffusion, extending the duration of cosmetic effect without complicating the manufacturing process

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent utilizes the porous or matrix structure of the polymer fiber to trap and slowly release cosmetic active ingredients. The internal architecture of the fiber acts as a reservoir, allowing ingredients to be held within the material and released over an extended period through controlled diffusion, thereby prolonging the cosmetic effect without requiring complex delivery systems

Inventive Principle:

Principle #31Porous materials
