Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Textile machines producing cross-wound bobbins face issues with contamination in thread traversing devices, leading to impaired production quality, increased downtimes, and resource wastage due to contamination accumulation, which affects the reproducibility and stability of the winding process.
Innovation Solution
A thread traversing device with a thread guide housing that employs an overpressure system using a fluid guide to clean the thread guide housing, featuring a defined exit point for pressure regulation and a control device for cyclic cleaning, along with design elements like guide rods and a sealing lip to prevent contamination accumulation and migration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the thread guide housing is used continuously without cleaning interruptions, then productivity is maintained, but contamination accumulates and impairs production quality
Solution Approach 1:
The patent implements continuous cleaning action through an integrated air nozzle system that operates simultaneously with the winding process. Compressed air is continuously supplied through channels in the thread guide housing to blow contaminants away from the thread guide, eliminating the need to stop production for cleaning while maintaining production quality.
Solution Approach 2:
The thread guide housing incorporates self-cleaning functionality through integrated air nozzles and channels that automatically remove contaminants during operation. The system uses the machine's own compressed air supply to clean the thread guide area, enabling the device to maintain itself without external intervention or production stoppage.
2Manufacturing precision
If cleaning interruptions are introduced to remove contaminants, then production quality is maintained, but downtime increases and productivity decreases
Solution Approach 1:
The patent applies preliminary cleaning action by positioning air nozzles to continuously blow contaminants away before they can accumulate and affect production quality. The compressed air flow prevents contaminant buildup proactively, eliminating the need for reactive cleaning interruptions and maintaining continuous productivity.
3Ease of manufacture
If the thread guide housing structure is simplified, then ease of manufacture increases, but contamination resistance and cleaning effectiveness decrease
Solution Approach 1:
The thread guide housing serves multiple functions simultaneously: it guides the thread, provides structural support, and incorporates integrated air channels for contaminant removal. The air nozzles are built into the housing structure itself, combining cleaning functionality with the guiding structure to maintain simplicity while enhancing contamination resistance.
Solution Approach 2:
The patent uses pneumatic principles by integrating compressed air channels and nozzles into the thread guide housing structure. The air flow is directed through channels formed within the housing to blow contaminants away, adding contamination removal capability without requiring separate complex cleaning mechanisms.
