Solution Overview

Problem

Current garments designed to manage perspiration are either uncomfortable for daily use or ineffective in hiding moisture, particularly for individuals with hyperhidrosis, as they either transport sweat to the outside or use thick, uncomfortable absorbent materials.

Innovation Solution

An insulating garment with an inner fabric made from synthetic polymer multifilaments that absorb perspiration and an outer fabric of polyester-cotton, featuring a low-perspiration distribution stitching method to create an air chamber for evaporation, enhancing comfort and moisture management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If adhesive cotton or cellulose elements are used to absorb perspiration, then perspiration absorption is improved, but garment thickness and comfort deteriorate

Engineering Contradiction:
Improveperspiration absorption capacityVSAvoidgarment thickness
Core Design Contradiction:
Quantity of substanceVSLength of stationary object

Solution Approach 1:

The patent applies local quality by treating only the inner fabric surface with hydrophilic properties for perspiration absorption, while the outer fabric remains hydrophobic. This localized treatment allows the garment to absorb perspiration effectively without requiring thick absorbent materials throughout the entire garment structure.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses composite materials by combining hydrophilic inner fabric layers with hydrophobic outer fabric layers. This composite structure enables the garment to absorb and retain perspiration internally while maintaining a thin, comfortable profile suitable for daily wear.

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If perspiration is transported to the outside, then moisture accumulation on the body is avoided, but perspiration becomes visible on the outer surface

Engineering Contradiction:
Improvemoisture accumulation on bodyVSAvoidvisible perspiration on outer surface
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful effect of perspiration transport into a beneficial internal absorption mechanism. The hydrophilic inner layer captures perspiration at the source and holds it within the fabric structure, preventing both body moisture accumulation and external visibility, effectively turning the moisture management challenge into a concealed absorption solution.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

By applying different surface properties to different layers - hydrophilic inner surface for absorption and hydrophobic outer surface for repellency - the patent locally manages moisture to prevent both accumulation and visibility issues simultaneously.

Inventive Principle:
Principle #3Local quality

3Productivity

If conventional perspiration management garments are used, then moisture transport is improved, but applicability for daily use deteriorates

Engineering Contradiction:
Improvemoisture transport efficiencyVSAvoidapplicability for daily use
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent achieves universality by designing a garment that performs both athletic moisture management and daily wear comfort functions. The dual-layer structure with hydrophilic-hydrophobic properties enables effective perspiration handling for active use while maintaining thin, comfortable, and discreet characteristics suitable for everyday clothing.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The composite fabric structure combines the moisture-wicking capabilities needed for athletic performance with the thin, comfortable profile required for daily wear, making the garment adaptable to multiple usage scenarios.

Inventive Principle:
Principle #40Composite materials

Applied Scientific Principles

AI summary

This invention refers to improvements obtained after multiple lines of research on all the elements and parts in the initial invention, namely threads, fibres stitches, finishes and fundamentally the creation of an air chamber between the two laminar structures that comprise the inner and outer fabric, which in addition to retaining humidity resulting from the user's perspiration, enables its subsequent evaporation.
