Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing winding carriers face issues with uneven dyeing and thread reserve displacement when stacked, leading to defective flow or overflow of yarn packages due to relative displacements between yarn layers, and the need for machine adjustments to accommodate different spool diameters.

Innovation Solution

A winding carrier design with a sliding brake on the additional collar that prevents thread reserve or thread end reserve from being pushed into the receptacle when spools are plugged together, ensuring both reserves are protected and easily accessible, compatible with machines set up for AC or eco-top tubes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If winding carriers are stacked axially for storage and transport, then space utilization is improved, but thread reserve displacement occurs leading to defective yarn flow

Engineering Contradiction:

Improvespace utilizationVSAvoidyarn flow quality

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The recess in the collar acts as an intermediary structure that receives and secures the thread reserve during axial stacking. The thread reserve is positioned in this recess, preventing it from being displaced when carriers are pressed together, thus maintaining yarn flow quality while enabling compact stacking.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The thread reserve is preliminarily positioned in the recess of the collar before stacking occurs. This preliminary placement ensures that when carriers are axially stacked and pressed together, the thread reserve is already secured and cannot be displaced, preventing defective yarn flow.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If thread reserve is wound on the collar edge, then unwinding is facilitated, but thread reserve is pushed into the receptacle when spools are plugged together

Engineering Contradiction:

Improveunwinding easeVSAvoidthread reserve accessibility

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The recess in the collar serves as an intermediary zone between the winding surface and the receptacle. It provides a dedicated space for the thread reserve that is accessible for unwinding operations yet protected from being pushed into the receptacle during stacking, as the recess geometry prevents further axial displacement.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The recess structure preliminarily counteracts the harmful action of the thread reserve being pushed into the receptacle. By providing a confined space with appropriate geometry, it preemptively prevents the displacement issue before it can occur during the plugging together of spools.

Inventive Principle:

Principle #9Preliminary anti-action

3Manufacturing precision

If winding carriers are pressed together for uniform dyeing, then dyeing homogeneity is improved, but thread reserve is displaced and lost

Engineering Contradiction:

Improvedyeing uniformityVSAvoidthread reserve loss

Core Design Contradiction:

Manufacturing precisionVSLoss of substance

Solution Approach 1:

The recess in the collar acts as a protective intermediary that holds the thread reserve securely during the pressing operation. When carriers are pressed together for uniform dyeing, the thread reserve remains confined in the recess and cannot be pushed into the receptacle or lost, thus preventing material loss while achieving dyeing homogeneity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The recess provides a cushioning space for the thread reserve before the pressing operation occurs. This preliminary protective structure ensures that when carriers are pressed together, the thread reserve is already positioned in a protected zone that prevents displacement and loss, maintaining both dyeing uniformity and material integrity.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Adaptability or versatility

If different receiving plate sizes are used for AC and eco-top tubes, then machine compatibility is improved, but device complexity increases

Engineering Contradiction:

Improvemachine compatibilityVSAvoidreceiving plate configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The collar design with the recess and the step on the additional collar creates a universal interface that can accommodate both AC and eco-top tube configurations. The same collar structure works with both machine setups, eliminating the need for different receiving plate sizes and reducing device complexity while maintaining machine compatibility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The invention provides various aspects of an improvement of winding carriers. The proposed winding carrier (1) enables for the first time to arrange both the thread reserve and the thread end reserve on a winding carrier such that they are protected when putting the bobbins together, yet easily accessible after the bobbins have been taken apart. Simultaneously the thread windings of two wound winding carriers come to rest at each other in a practically direct manner.
