Solution Overview

Problem

Synthetic materials used in garments, such as gloves, often lack sensitivity to touch and dexterity due to their inherent properties, which are not water-repellent, breathable, or fireproof, and do not effectively enhance tactile sensation.

Innovation Solution

A covering with projections of varying heights and apex forms made from a polymer material that can be integrated into garments to improve touch sensitivity, allowing for air ventilation, moisture wicking, and cooling, while simulating finger contact and adhesive properties by penetrating the carrier material, which can be used on the inside or outside of garments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If synthetic materials are used for production of a glove, then manufacturing control, productivity and quality consistency are improved, but dexterity and sensitivity to touch deteriorate

Engineering Contradiction:
Improvemanufacturing productivityVSAvoiddexterity and sensitivity to touch
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent applies local quality by creating projections with varying heights and apex forms (acute, rounded, flat) at specific locations on the glove surface. These localized structural variations enhance tactile sensitivity and dexterity in gripping regions while maintaining the overall synthetic material benefits for manufacturing consistency and productivity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces a third dimension by adding projections that extend outward from the base surface of the synthetic material. This dimensional addition creates a textured surface structure that improves touch sensitivity and dexterity without compromising the underlying synthetic material's manufacturing advantages.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by varying the height, apex form (acute, rounded, flat), and distribution of projections to optimize touch sensitivity. These parameter variations are integrated into a single molding process, allowing complex tactile properties to be achieved without proportionally increasing manufacturing complexity.

Inventive Principle:
