Solution Overview

Problem

Conventional knitting methods require tools and skilled labor, making it difficult for untrained individuals to create knitted products quickly and efficiently, and they lack the ability to produce items with distinct patterns and properties on both sides.

Innovation Solution

A knitting yarn with a thread and affixed loops that can be manually manipulated into rows, allowing loops from one set to be threaded through those of another, enabling the creation of knitted products without tools and with symmetrical loop sets for differing patterns and properties on each surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional knitting methods using tools and skilled labor are employed, then knitting precision and structural complexity can be achieved, but the ease of operation deteriorates and requires significant training time

Engineering Contradiction:
Improveknitting precisionVSAvoidease of operation
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The yarn is segmented into multiple functional components: a core strand, effect strands, and binder strands. This segmentation allows each component to serve a specific function, with the binder strand automatically securing loops without requiring manual manipulation, thus maintaining precision while improving ease of operation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The binder strand automatically secures the effect strands to the core strand through self-binding action. The yarn structure enables automatic loop formation and securing without requiring external tools or skilled manual intervention, making the knitting process accessible to untrained individuals

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If traditional knitting tools and methods are used, then complex knitting patterns can be created, but the productivity deteriorates due to time-consuming manual processes

Engineering Contradiction:
Improvepattern complexityVSAvoidproductivity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The loops and binder strands are pre-configured on the yarn during manufacturing. This preliminary arrangement of loops and binding elements allows the yarn to be knitted simply by pulling and looping without time-consuming manual knot-tying or tool manipulation, significantly improving productivity while maintaining pattern versatility

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention changes the fundamental parameter of yarn structure from a simple continuous strand to a complex pre-formed structure with integrated loops and binders. This parameter change transforms the knitting process from a skill-intensive manual craft to a simple repetitive action that can be performed quickly by anyone

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If single-sided loop extension is used as in prior art, then manufacturing simplicity is maintained, but the adaptability deteriorates by inability to create distinct front and back surfaces

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidsurface differentiation
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The yarn incorporates asymmetric loop arrangements with different loop sets oriented in opposite directions. This asymmetry allows the creation of knitted products with distinct front and back surfaces having different patterns and properties, while the loops remain affixed to the same core strand, maintaining manufacturing simplicity

Inventive Principle:
Principle #4Asymmetry

AI summary

The present invention proposes a knitting yarn for manually forming a knitted product without tools comprising a thread having a length dimension extending along an axis (A); a plurality of loops affixed to or formed with said thread by extending outwardly of said thread; and each of said plurality of loops defining an interior space adapted to receive another loop of said plurality of loops. Said plurality of loops includes a first loop set mainly extending outwardly along +y axis and a second loop set extending along -y axis; and, said first loop set is essentially symmetrical to said second loop set around said symmetry axis (A). The present invention further proposes a method of manually forming a knitted product and the knitted product obtained by the method according to the present invention.
