Solution Overview

Problem

The existing take-up apparatuses for winding yarns spun by a melt spinning machine around winding bobbins are cumbersome to install and maintain due to separately disposed devices, and sharing a supporting member for multiple apparatuses is difficult without increasing size or complicating the configuration.

Innovation Solution

A take-up apparatus with a yarn feeding unit that includes a first and second godet roller, supported by a first beam arranged between yarn paths, allowing for adjustable mounting and sharing of the supporting member across multiple apparatuses, facilitating installation and maintenance while avoiding interference with yarn paths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If devices are separately disposed on a frame, then each device can be independently positioned, but installation and maintenance become cumbersome

Engineering Contradiction:
Improveinstallation and maintenance easeVSAvoiddevice arrangement complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges multiple separately disposed devices (rollers, yarn guides, cutting-and-sucking devices) into an integrated yarn feeding unit. This consolidation allows the entire unit to be attached or detached as a single assembly, significantly simplifying installation and maintenance operations while reducing the complexity of managing multiple separate components.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If the supporting member is disposed in the space including yarn paths, then it can support the yarn feeding unit, but it interferes with the yarn paths

Engineering Contradiction:
Improvesupporting member accessibilityVSAvoidyarn path interference
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The supporting member is positioned in the vertical dimension above the yarn feeding unit, rather than laterally within the horizontal yarn path space. This vertical placement allows the supporting member to provide necessary support while completely avoiding interference with the horizontal yarn paths, resolving the spatial conflict between support structure and yarn flow.

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

3Area of stationary object

If multiple take-up apparatuses share a supporting member, then installation space is saved, but the supporting member position becomes extremely high

Engineering Contradiction:
Improveinstallation spaceVSAvoidattachment and detachment ease
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The support structure is segmented into local supporting members for each take-up apparatus rather than using a single shared supporting member. Each local supporting member is positioned close to its corresponding yarn feeding unit at an accessible height, enabling easy attachment and detachment while avoiding the need for an extremely high shared support structure that would complicate installation.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If the frame protrudes from the back surface side, then the supporting member can be positioned, but the take-up apparatus becomes larger and more complicated

Engineering Contradiction:
Improvesupporting member positioningVSAvoidtake-up apparatus size
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

Instead of having the frame protrude from the back surface side to accommodate the supporting member, the design inverts the approach by integrating the supporting member within the compact front surface area where the yarn feeding unit is located. This inversion eliminates the need for frame protrusions, maintaining a compact apparatus size while providing necessary support functionality.

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