Solution Overview

Problem

Existing gloves and socks made of absorbent materials like cotton or gel linings fail to effectively retain moisture on the skin due to absorption, causing sweating and preventing airflow, while also limiting dexterity and fine motor skills.

Innovation Solution

A three-layer material system comprising a breathable inner fabric layer, an impermeable but breathable intermediate layer, and an external protective layer, which prevents liquid absorption and allows vapor transfer, providing moisture retention and protection from UV and heat.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If gloves are made of cotton or absorbent materials to retain moisture on hands, then moisture is kept on the skin, but the materials absorb too much moisture and become ineffective

Engineering Contradiction:

Improvemoisture retention on skinVSAvoidmoisture absorption by glove material

Core Design Contradiction:

Quantity of substanceVSLoss of substance

Solution Approach 1:

The glove uses a polymeric foam material with controlled porosity that allows moisture vapor to pass through while preventing liquid moisture from being absorbed. The foam structure provides pathways for vapor transmission while the cell structure prevents capillary action that would draw liquid moisture into the material.

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The invention combines multiple materials with complementary properties: an inner layer for moisture management, a polymeric foam intermediate layer for vapor transmission and liquid barrier, and an outer protective layer. This composite structure achieves both moisture retention and breathability that single materials cannot provide.

Inventive Principle:

Principle #40Composite materials

2Object-affected harmful factors

If gloves are made of heavy fabric to protect skin, then protection is provided, but airflow is prevented and hands get hot and sweaty

Engineering Contradiction:

Improveprotection from environmental factorsVSAvoidhand temperature and sweating

Core Design Contradiction:

Object-affected harmful factorsVSTemperature

Solution Approach 1:

The polymeric foam layer acts as a breathable barrier that transmits heat and moisture vapor while blocking external environmental factors. The porous structure allows thermal energy and vapor to pass through, preventing heat buildup while maintaining protective function.

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The glove uses thin film structures that provide protection without the bulk and heat retention of heavy fabrics. The flexible foam and film layers conform to the hand while allowing thermal exchange, preventing the greenhouse effect of thick materials.

Inventive Principle:

Principle #30Flexible shells and thin films

3Quantity of substance

If gloves are closed around fingers to moisturize skin, then moisture is retained, but dexterity and fine motor skills are limited

Engineering Contradiction:

Improvemoisture retentionVSAvoiddexterity and fine motor skills

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The glove is segmented into separate finger sheaths that can move independently, allowing full range of motion and dexterity. Each finger portion is contoured to match natural finger anatomy, enabling precise movements while maintaining moisture retention within each segmented chamber.

Inventive Principle:

Principle #1Segmentation

4Quantity of substance

If socks are made of cotton or gel lining to retain moisture on feet, then moisture is kept against skin, but feet get hot and sweaty due to prevented airflow

Engineering Contradiction:

Improvemoisture retention on skinVSAvoidmoisture vapor transmission

Core Design Contradiction:

Quantity of substanceVSLoss of substance

Solution Approach 1:

The polymeric foam material in the sock provides vapor-permeable structure that allows moisture vapor to escape from the foot while preventing liquid moisture absorption. The porous network enables vapor diffusion pathways that maintain breathability and prevent sweating.

Inventive Principle:

Principle #31Porous materials

AI summary

A multi-layer material system used to form various products that encourages moist substances or medications to stay on and penetrate a person's skin for moisturizing benefits and protection, as well as for medical treatment. The system enables a degree of outward vapor and air flow while preventing bulk transfer of the moist substances. Simultaneously, the system provides resistance to, and protection from, external elements including one or more of heat, ultraviolet radiation and mechanical abrasion.
