Solution Overview

Problem

The existing yarn winding systems require extensive time and effort to change settings when the winding units are modified, as multiple setting items in the transportation apparatus need to be adjusted accordingly, leading to inefficiencies in operation.

Innovation Solution

A yarn winding system with a control device that utilizes pre-defined setting lots for both the transportation apparatus and winding units, allowing for collective setting changes through stored setting contents, displayed on a user interface for easy recognition and management, ensuring compatibility and reducing manual effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the setting of the winding units is changed, then the adaptability of the system to different production requirements is improved, but the time and effort required to change the setting of the transportation apparatus increases

Engineering Contradiction:
Improveadaptability to different yarn typesVSAvoidsetting change time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system pre-defines multiple setting lots containing predetermined combinations of setting items for the transportation apparatus. When a winding unit setting change is required, the corresponding pre-defined setting lot is automatically selected and applied, eliminating the need to manually configure each setting item individually. This preliminary preparation of setting combinations directly resolves the contradiction by enabling quick adaptation without time-consuming manual configuration.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Multiple related setting items (yarn type, transportation speed, bobbin handling parameters) are merged into a single setting lot unit. By combining these settings that must change together into one selectable package, the system allows operators to change all relevant settings simultaneously by selecting one setting lot, thereby improving adaptability while reducing the time and effort required for setting changes.

Inventive Principle:
Principle #5Merging (Combining)

2Manufacturing precision

If multiple setting items are configured individually, then the precision of each setting parameter is maintained, but the complexity of the setting process increases

Engineering Contradiction:
Improvesetting parameter accuracyVSAvoidsetting process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Multiple setting items are merged into unified setting lots that preserve the accuracy of each individual parameter while simplifying the overall setting process. Each setting lot contains pre-configured values for yarn type, transportation speed, and other parameters, ensuring that precise settings are maintained without requiring operators to manually configure each parameter separately.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system performs preliminary configuration of setting combinations by experts or system analysts, who optimize each setting parameter for specific yarn types and production requirements. These pre-optimized settings are stored as setting lots, ensuring manufacturing precision is maintained while reducing the complexity of the setting process for operators who simply need to select the appropriate preset combination.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If manual configuration of each setting item is performed, then the flexibility to customize individual parameters is improved, but the labor effort required increases

Engineering Contradiction:
Improveparameter customization flexibilityVSAvoidsetting operation ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system merges multiple setting items into selectable setting lots, providing ease of operation through automatic configuration while maintaining adaptability through the availability of different preset combinations. Operators can quickly adapt to different yarn types by selecting appropriate setting lots without manually configuring each parameter, significantly reducing labor effort while preserving the flexibility to handle various production requirements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system provides self-service functionality by automatically selecting and applying the appropriate setting lot based on the yarn type and production requirements. This automation eliminates the need for manual configuration of each setting item, reducing labor effort while maintaining the flexibility to adapt to different conditions through pre-configured setting combinations that can be selected as needed.

Inventive Principle:
Principle #25Self-service
