Solution Overview

Problem

Existing composite parts emitting far infrared radiation for skin contact lack effective adhesion and uniform application, leading to potential displacement during movement and uneven distribution of metal oxides, which hampers their beneficial health and cosmetic effects.

Innovation Solution

A composite part with a textile base incorporating a sticky paste of metal oxides and a hydrophilic component, where the paste is partially embedded within the textile to form a thick interface layer, ensuring adhesion and distributing metal oxides over a significant thickness while allowing water diffusion for enhanced effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a material emitting far infrared is associated with an internal surface of a patch fixed to the skin using an adhesive, then the position of the patch is maintained, but the internal surface may wrinkle, ripple, or crease resulting in uneven application

Engineering Contradiction:
Improvepatch position stabilityVSAvoidapplication uniformity
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent uses a flexible textile base instead of a rigid internal surface to prevent wrinkling and rippling. The textile base can conform to skin contours without creasing, maintaining both patch stability and application uniformity.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent creates a composite structure by embedding metal oxide particles within a textile base matrix. This composite material combines the adhesion properties of the textile with the far-infrared emitting properties of metal oxides, eliminating the need for separate adhesive layers that cause wrinkling.

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If metal oxide particles are distributed over a significant thickness of the composite part, then the beneficial health effects are enhanced, but the strength of the composite part may be compromised

Engineering Contradiction:
Improvemetal oxide distributionVSAvoidcomposite part strength
Core Design Contradiction:
Quantity of substanceVSStrength

Solution Approach 1:

The patent utilizes the porous structure of the textile base to distribute metal oxide particles throughout its thickness. The textile's natural porosity allows high particle loading without compromising structural integrity, as the fibrous network provides mechanical strength while accommodating the particles.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The patent embeds metal oxide particles within the textile base structure, nesting the functional particles inside the mechanical framework of the textile. This nesting approach allows significant particle distribution while the outer textile structure maintains composite part strength.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If the inner layer thickness is increased to improve adhesion, then continuous contact with skin is achieved, but the layer may float or collapse degrading adhesion properties

Engineering Contradiction:
Improveskin contact continuityVSAvoidlayer structural stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent employs a flexible textile base that maintains structural stability while conforming to skin contours. The textile's inherent flexibility and strength prevent floating or collapse even when thin, ensuring continuous skin contact without degrading adhesion properties.

Inventive Principle:
Principle #30Flexible shells and thin films
