Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
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
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.
