Reflective Knit Article Float Plaiting for Stretch and Visibility

Solution Overview

Problem

Existing reflective garments for outdoor activities are often uncomfortable, aesthetically unappealing, and compromise the flexibility and stretchability required for athletic pursuits due to the incorporation of less elastic reflective yarns.

Innovation Solution

A method involving float plaiting stitching and selective cutting and joining of knit articles to incorporate reflective yarns, maintaining flexibility and stretchability by using a first yarn with higher elasticity and a reflective yarn with lower elasticity, and securing the reflective yarn with additional slack and plaiting yarns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If reflective yarn is incorporated into knit articles, then visibility is improved, but flexibility and stretchability deteriorate

Engineering Contradiction:

ImprovevisibilityVSAvoidflexibility and stretchability

Core Design Contradiction:

Illumination intensityVSEase of operation

Solution Approach 1:

The patent applies local quality by incorporating reflective yarn selectively in specific regions of the knit article rather than uniformly throughout. The reflective yarn is placed in zones where visibility enhancement is most needed (such as edges, seams, or high-visibility areas) while leaving other regions with only elastic knit yarn, thus maintaining flexibility and stretchability in non-critical areas.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent uses composite materials by combining reflective yarn with elastic knit yarn in a single knit structure. This composite approach allows the article to exhibit both reflective properties (from the reflective yarn) and elastic properties (from the knit yarn), resolving the contradiction between visibility and flexibility.

Inventive Principle:

Principle #40Composite materials

AI summary

A method of manufacturing a knit article having a reflective yarn. The method includes knitting an article using a first yarn, and knitting a reflective yarn into a first region of the article using a float plaiting stitch. The method further includes cutting the article incorporating the reflective yarn according to a predetermined pattern to form a cut knit article having a first edge and an opposing second edge, and joining the first edge of the cut knit article to the second edge of the cut knit article.
