Solution Overview

Problem

Existing devices for texturing and winding multiple threads are not compactly arranged and are not adaptable to varying production speeds, leading to inefficiencies in thread production, particularly in melt spinning and texturing processes.

Innovation Solution

The cooling device, twisting device, and at least one delivery roller are aligned in the same direction as the winding spindle, allowing for a compact and variable arrangement that minimizes machine pitch and eliminates the need for additional thread deflections, enabling a straight yarn path through the texturing zone for gentle crimping and post-heat treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the cooling device, twisting device and delivery rollers are arranged in a vertical arrangement (conventional design), then the devices can process multiple threads, but the machine pitch becomes large and the arrangement is not compact

Engineering Contradiction:
Improvemachine pitchVSAvoidarrangement complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent transitions from a vertical arrangement to a horizontal arrangement of the texturing zone, aligning it parallel to the winding spindle instead of perpendicular. This dimensional change allows the cooling device, twisting device, and delivery rollers to be positioned horizontally, significantly reducing the machine pitch and creating a more compact overall structure while maintaining processing capability for multiple threads

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If additional thread deflections and guides are added to accommodate non-parallel arrangement, then threads can be guided to winding points, but the texturing process becomes more complex and harsh

Engineering Contradiction:
Improvethread guidanceVSAvoidthread path complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent eliminates the need for additional thread deflections and guides by directly aligning the texturing zone parallel to the winding spindle. This extraction of unnecessary intermediate components simplifies the thread path, allowing threads to travel in a straight line from the delivery rollers through the texturing zone to the winding points, thereby reducing operational complexity and preventing harsh treatment of the threads

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If the texturing zone is arranged perpendicular to the winding spindle (conventional design), then winding can be performed, but the distance between devices must be large reducing productivity

Engineering Contradiction:
Improveproduction speedVSAvoiddistance between devices
Core Design Contradiction:
ProductivityVSLength of stationary object

Solution Approach 1:

The patent merges the texturing zone and winding device into a closely integrated horizontal arrangement, with the texturing zone positioned directly above the winding device and both aligned parallel to each other. This merging eliminates the need for large distances between devices, allowing the thread path to be short and direct, thereby increasing production speed and productivity

Inventive Principle:
Principle #5Merging (Combining)

4Volume of moving object

If the texturing zone is arranged parallel to the winding spindle with minimal distance, then machine pitch is reduced, but precise alignment and positioning become more difficult

Engineering Contradiction:
Improvemachine pitchVSAvoidalignment precision
Core Design Contradiction:
Volume of moving objectVSManufacturing precision

Solution Approach 1:

The patent employs preliminary alignment actions during the design and setup phase, positioning the texturing zone and winding device in their final horizontal parallel arrangement before operation. The delivery rollers are pre-positioned to ensure straight thread paths, and the entire system is configured to maintain precise alignment, thereby achieving minimal machine pitch while ensuring the necessary manufacturing precision through advance preparation

Inventive Principle:
Principle #10Preliminary action
