Solution Overview

Problem

Conventional light-reflective strips on clothing are not aesthetically pleasing and unsuitable for general wear, compromising their usability in various occasions.

Innovation Solution

A light-reflective mark formed with light-reflective yarn, integrated into knitted or sewn patterns on articles, providing a reflective safety function while maintaining a fashionable appearance, by using a combination of light-reflective yarns for sewing, embroidery, or weaving, allowing the mark to be hidden within the fabric until illuminated.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If light-reflective strips are disposed on clothes in the form of strap or band, then the light-reflective effect is achieved, but the aesthetic appearance and fashionability deteriorate

Engineering Contradiction:
Improvelight-reflective safety functionVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The light-reflective strip is segmented into multiple light-reflective yarns that are woven into the fabric at different positions and orientations. Each yarn segment reflects light independently, and collectively they form a complete light-reflective pattern that is both functional and aesthetically pleasing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The light-reflective yarns are merged with the base fabric yarns during the weaving process, creating a unified textile structure. The light-reflective yarns are interwoven with ordinary yarns to form patterns such as logos, text, or decorative designs, making the safety function integrated into the clothing's aesthetic design.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If light-reflective strips are disposed on clothes, then the safety function is improved, but the device complexity and manufacturing complexity increase

Engineering Contradiction:
Improvelight-reflective safety functionVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The weaving process is designed to serve multiple functions simultaneously: it creates the base fabric structure, integrates light-reflective yarns, forms aesthetic patterns, and ensures proper light reflection. This multi-functionality eliminates the need for separate steps of attaching light-reflective strips after fabric production.

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

Solution Approach 2:

The light-reflective yarns are self-integrated into the fabric during the weaving process, eliminating the need for external attachment processes. The weaving machine automatically places and secures the light-reflective yarns in the desired patterns as part of the normal fabric production workflow.

Inventive Principle:
Principle #25Self-service

3Reliability

If light-reflective yarns are used to form complete patterns, then the light-reflective effect is maximized, but the cost and weight increase

Engineering Contradiction:
Improvelight-reflective effectVSAvoidweight of clothing
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

Light-reflective yarns are strategically placed only in specific locations where they are most needed for safety and aesthetic purposes, such as along seam lines, in logo areas, or in patterns that align with natural light reflection paths. This localized placement reduces the overall quantity of light-reflective yarns required compared to complete coverage.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs partial action by using light-reflective yarns to create patterns that are visually complete but physically partial in terms of material usage. The woven patterns may appear solid from a distance but are actually composed of spaced yarn segments that allow light transmission and reduce material consumption.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

The invention provides a light-reflective mark (20) formed with light-reflective yarn (22). The light-reflective mark is made on a sheet material (10), the sheet material is an article that can be sewn or embroidered or a knitted fabric; the light-reflective mark is a pattern formed with graphics and/or texts, and is formed by combining one or more than one light-reflective yarns with the sheet material by sewing, embroidery or weaving. Thereby, daily supplies or clothing can be provided with the light-reflective mark of the invention, so as to improve the safety of daily activities. The light-reflective mark can be made into an aesthetic pattern, or a pattern or a text with a specific shape, such as graphic or text of a logo, so that the article or clothing with the light-reflective mark is fashionably and aesthetically pleasing.
