Solution Overview

Problem

Existing spinning devices require frequent replacement of supply spools and maintenance to adapt to different threads, leading to inefficiencies and errors, especially in modern machines that spin multiple threads.

Innovation Solution

A spinning device with a template thread device that stores a reusable template thread independently of the spun thread, allowing each workstation to spin a new thread independently without relying on a mobile service device, and a service device that refills the template thread when necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a mobile service device with auxiliary yarn supply is used, then thread supply flexibility is improved, but device complexity and maintenance intensity increase

Engineering Contradiction:
Improvethread supply flexibilityVSAvoidservice device complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system is divided into independent workstation units, each equipped with its own template thread device. This segmentation eliminates the need for a centralized mobile service device, reducing overall system complexity while maintaining thread supply flexibility at each station.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each workstation is equipped with a template thread device that automatically supplies template threads without requiring external service intervention. The system serves itself by locally storing and providing the necessary threads, eliminating dependency on mobile service devices.

Inventive Principle:
Principle #25Self-service

2Reliability

If supply spools must be matched to thread types, then thread compatibility is ensured, but operational time and maintenance intensity increase

Engineering Contradiction:
Improvethread compatibilityVSAvoidspool replacement time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Template threads are pre-stored in the template thread device at each workstation before being needed. This preliminary preparation allows immediate use of the correct template thread without requiring time-consuming spool replacement or matching operations when thread changes are required.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple auxiliary threads are kept for different spinning operations, then operational versatility is improved, but device complexity and thread consumption increase

Engineering Contradiction:
Improvespinning operation versatilityVSAvoidthread consumption
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The template thread device provides a universal template thread that can be used for multiple spinning operations and thread types. This single multi-functional template replaces the need for multiple specialized auxiliary threads, reducing total thread quantity required while maintaining operational versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)
