Solution Overview

Problem

Existing gloves struggle to balance impact-dampening, cut-resistance, flexibility, comfort, and ease of manufacturing, often requiring additional materials and complex manufacturing processes.

Innovation Solution

A seamless knitted glove design featuring knitted ridges formed with varying yarns and tensions, using machines like NSFG and SFG-1, which eliminates the need for sewing and provides reinforcement for impact and abrasion protection while maintaining flexibility and grip.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional materials and complex manufacturing processes are used to achieve impact-dampening and cut-resistance, then protection performance is improved, but device complexity and ease of manufacture deteriorate

Engineering Contradiction:
Improveprotection performanceVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple protective functions (impact-dampening, cut-resistance, abrasion resistance) into a single seamless knitted glove structure. The ridge patterns are integrated directly into the knitting process using the same or similar yarns, eliminating the need for separate protective layers, coatings, or additional materials. This merging approach maintains protection performance while significantly simplifying the manufacturing process.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The knitted ridge structure serves multiple protective functions simultaneously: it provides impact-dampening through its raised geometry, cut-resistance through the reinforced yarn paths, and abrasion resistance through the enhanced surface texture. This multi-functionality is achieved within a single manufacturing process, avoiding the need for separate components or materials for each protective function.

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

2Reliability

If reinforced structures are added to gloves for impact and cut-resistance, then protection performance is improved, but flexibility and comfort deteriorate

Engineering Contradiction:
Improveprotection performanceVSAvoidflexibility and comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent implements protective ridge patterns only in specific high-risk areas such as the palm, fingers, and knuckles, rather than uniformly across the entire glove. This localized reinforcement provides necessary protection in critical zones while maintaining flexibility and comfort in less vulnerable areas, resolving the contradiction between protection and ease of operation.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The protective ridges are constructed using flexible knitted yarns that can bend and stretch with the glove material. The ridge structure is integrated into the knitted fabric itself, allowing it to deform flexibly with hand movements while still providing impact and cut protection. This flexibility is maintained through the inherent elasticity of the knitted structure and the choice of yarn materials.

Inventive Principle:
Principle #30Flexible shells and thin films

3Ease of manufacture

If seamless knitting process is used to simplify manufacturing, then ease of manufacture is improved, but ability to provide reinforcement deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidprotection performance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent achieves reinforcement within the seamless knitting process by changing key parameters: using yarns with different deniers (thicknesses), varying yarn tensions during knitting, and adjusting stitch patterns to create raised ridge structures. These parameter changes allow the single knitting process to produce both the base glove material and the reinforced protective elements, maintaining manufacturing simplicity while achieving protection performance.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite yarn constructions within the seamless knitting process, combining different fiber types or yarn structures (e.g., high-tenacity fibers, aramid blends, or multi-component yarns) that provide enhanced protection properties. These composite materials are knitted directly into the glove structure, allowing the seamless process to produce reinforcement without requiring separate materials or assembly steps.

Inventive Principle:
Principle #40Composite materials
