Glove External Thumb Seam Inversion for Comfort

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Protective gloves often feature seams that cause discomfort for the wearer, particularly in sensitive areas like the palm, due to their internal location which can lead to friction and pressure issues during use.

Innovation Solution

Designing a glove with a majority of internal seams and an external thumb seam that extends along the palm, allowing for easier movement and reduced friction by positioning the seam as a natural pivot point, thereby enhancing comfort and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If seams are positioned internally to minimize visibility and fraying, then aesthetic appearance is improved, but comfort and ease of movement deteriorate due to friction and pressure on the wearer's hand

Engineering Contradiction:

Improveaesthetic appearanceVSAvoidcomfort and ease of movement

Core Design Contradiction:

ShapeVSEase of operation

Solution Approach 1:

The patent inverts the conventional seam placement by positioning the thumb seam externally rather than internally. This inversion allows the seam to serve as a natural pivot point for thumb movement, improving comfort and ease of operation while maintaining aesthetic appearance through strategic placement

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If seams are positioned internally to minimize fraying, then durability is improved, but friction and pressure on the wearer's hand increase causing discomfort

Engineering Contradiction:

ImprovedurabilityVSAvoidfriction and pressure

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by making only the thumb seam external while keeping other seams internal. This localized external placement provides a pivot point for thumb movement without exposing all seams to friction and pressure, thereby maintaining durability while reducing discomfort in specific high-friction areas

Inventive Principle:

Principle #3Local quality

AI summary

A glove including a plurality pieces of material coupled together along a plurality of seams to form a glove. A majority of the seams of the glove, as measured along their length, are not external seams, and a thumb seam extending along or through a palm of the glove is an external seam.
