Solution Overview

Problem

Existing methods for producing fancy yarns lack a definitive production process, particularly in integrating decorative fibers intermittently cut and tangled with a main yarn, limiting the ability to arbitrarily regulate structure intervals and magnitudes, and providing distinct colors.

Innovation Solution

A production device incorporating a main feeding creel, jet nozzle, cutter, and twisting device to intermittently cut decorative yarns, which are then tangled with a main yarn using air flow and twisted to form a fancy yarn, allowing for adjustable structure intervals and colors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If decorative yarn is intermittently cut and tangled with main yarn to produce fancy yarn, then decorative effects and color variety are improved, but the ability to arbitrarily regulate structure intervals and magnitudes is limited

Engineering Contradiction:
Improvedecorative effectsVSAvoidstructure interval regulation
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent uses a jet nozzle to blow air flow onto the main yarn and cut decorative yarn, causing the decorative yarn to fly and tangle with the main yarn. This pneumatic mechanism enables arbitrary regulation of structure intervals and magnitudes by controlling air flow parameters, while maintaining excellent decorative effects through the tangled structure.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Productivity

If existing fancy yarn production methods are used, then yarn production is achieved, but the integration of intermittently cut decorative fibers with main yarn is limited

Engineering Contradiction:
Improveyarn productionVSAvoiddecorative fiber integration
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent introduces air flow as an intermediary between the cut decorative yarn and the main yarn. The air flow carries the cut decorative yarn segments and deposits them onto the main yarn, achieving precise integration and tangled structure that existing methods cannot accomplish.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If decorative yarn is made to fly and tangle with main yarn using air flow, then structure intervals and colors can be arbitrarily regulated, but device complexity increases

Engineering Contradiction:
Improvestructure interval regulationVSAvoidproduction device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The jet nozzle serves multiple functions: it blows air flow to make decorative yarn fly, cuts the decorative yarn intermittently, and controls the tangling process. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while enabling arbitrary regulation of structure intervals and colors.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables the production of fancy yarns with arbitrarily regulated structure intervals and distinct colors, ensuring decorative fibers securely tangle with the main yarn, enhancing decorative effects.

Implementation Method 1

a jet nozzle for feeding the decorative yarn along with air flow to the confluence region; the cut decorative yarn is blown by and flies with the air flow of the jet nozzle

AI summary

A production device for a fancy yarn including a main yarn and a decorative yarn intermittently cut and tangled in the main yarn is provided with a confluence region to put the decorative yarn along the main yarn; a main feeding creel for feeding the main yarn to the confluence region; a jet nozzle for feeding the decorative yarn along with air flow to the confluence region; a cutter to intermittently cut the decorative yarn; and a twisting device to create a real twist or a false twist in the main yarn with the decorative yarn.
