Solution Overview

Problem

In textile machines, incorrect manual insertion of spool sleeves into core magazines leads to defective spools and interrupted spinning processes, increasing resource requirements and costs.

Innovation Solution

A core magazine with a marking device assigned to a plane between holders, allowing for automated feeding and manual assignment of spools to specific areas, using color codes to distinguish between yarn batches.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual insertion of spool sleeves is used, then ease of operation is improved, but manufacturing precision deteriorates leading to incorrect spool placement

Engineering Contradiction:
Improveease of operationVSAvoidmanufacturing precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies color coding through marking devices (colored strips, bands, or labels) that are visually distinct and correspond to different yarn batches. Operators can quickly identify and place spool sleeves of the correct color in the appropriate sections, eliminating confusion between batches while maintaining manual operation simplicity.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The core magazine is divided into multiple sections, each dedicated to a specific yarn batch. The marking devices are positioned at the boundaries between sections to clearly demarcate them. This segmentation allows operators to systematically place spool sleeves in the correct sections without errors.

Inventive Principle:
Principle #1Segmentation

2Productivity

If automated feeding is implemented, then productivity is improved, but device complexity increases

Engineering Contradiction:
ImproveproductivityVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The marking devices serve as intermediaries that bridge the automated feeding system and the yarn batch identification requirement. Instead of complex automated recognition systems, the marking devices provide simple visual cues that automated mechanisms can reliably detect and respond to, reducing overall system complexity while maintaining automation benefits.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple yarn batches are produced, then adaptability is improved, but manufacturing precision deteriorates due to potential mix-ups

Engineering Contradiction:
ImproveadaptabilityVSAvoidmanufacturing precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Each yarn batch is assigned a unique color code through marking devices on the core magazine sections. This color-coding system allows the textile machine to efficiently switch between multiple yarn batches while maintaining precise identification and placement, preventing mix-ups between different batches.

Inventive Principle:
Principle #32Color changes
