Solution Overview

Problem

Existing spinning winders require a large installation area due to movable godet rollers or distribution guides, limiting design freedom and complicating the yarn threading process.

Innovation Solution

A spinning winder design featuring a small and light yarn holding component that moves along distribution guides while the godet roller and distribution guides remain stationary, using a rod-shaped component with grooves to align and thread yarns onto distribution guides in a simple and efficient manner.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the godet roller or distribution guides are arranged to be movable to move yarns to corresponding distribution guides, then yarn threading is achieved, but a very large installation area is required

Engineering Contradiction:
Improveyarn threading capabilityVSAvoidinstallation area
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

Instead of moving the godet roller or distribution guides to achieve yarn threading, the patent inverts the approach by making the yarn holding component movable while keeping the godet roller and distribution guides stationary. This reversal of which component moves resolves the contradiction by enabling yarn threading without requiring large installation area for moving major components.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent extracts the movement function from the godet roller and distribution guides, concentrating it solely in the small yarn holding component. By taking out the movement requirement from large stationary components and placing it in a small portable component, the system achieves yarn threading capability without compromising installation area.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the godet roller or distribution guides are arranged to be movable to move yarns to corresponding distribution guides, then yarn threading is achieved, but design freedom is limited

Engineering Contradiction:
Improveyarn threading capabilityVSAvoiddesign freedom
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent applies inversion by making the yarn holding component movable instead of moving the godet roller or distribution guides. This design choice enhances adaptability and versatility because the small movable yarn holding component can be easily repositioned and adapted to different configurations without being constrained by the fixed positions of large stationary components.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent introduces dynamics by making the yarn holding component movable while keeping other components stationary. This dynamic element provides design freedom as the movable component can be positioned flexibly to accommodate different yarn threading requirements without altering the fixed infrastructure of the spinning winder.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the godet roller or distribution guides are arranged to be movable to move yarns to corresponding distribution guides, then yarn threading is achieved, but the structure becomes complex

Engineering Contradiction:
Improveyarn threading capabilityVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the movement function from complex stationary components (godet roller and distribution guides) and concentrates it in a simple movable yarn holding component. This extraction simplifies the overall structure by eliminating the need for complex mechanisms to move large components, while maintaining the essential yarn threading capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

By inverting which component moves (making the small yarn holding component movable instead of the large godet roller or distribution guides), the patent significantly reduces structural complexity. The movable yarn holding component requires simpler actuation and positioning mechanisms compared to moving the entire godet roller or distribution guide assembly.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

Yarns threaded on a godet roller are fed to corresponding distribution guides by a simple structure. A spinning winder includes components such as two godet rollers 11 and 12 receiving yarns 10 supplied from a spinning machine, fulcrum guides 13a to 13d which are aligned in crosswise directions along a bobbin holder and distribute the yarns 10 wound onto the downstream-side godet roller 12 to bobbins attached to the bobbin holder, respectively, and a yarn threading guide 20 which is arranged to be movable in the alignment directions of the fulcrum guides 13a to 13d between the fulcrum guides 13a to 13d and the bobbin holder, while holding the yarns 10.
