Multi-nozzle junction for textile machine conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile machines require time-consuming and costly conversions between compression devices and conventional thread suction devices, making it difficult to retrofit and switch between these configurations efficiently.
Innovation Solution
A multi-nozzle connection system that allows for easy detachment and pivoting of compression or suction devices, using a holder with spaced support members and a clip connection, enabling quick alignment and sealing, and allowing the devices to assume different positions for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compression device is permanently installed after the drafting unit, then the yarn quality can be ensured, but the machine conversion time and cost increase significantly
Solution Approach 1:
The compression device is divided into separate modular components (compression element, holder, drive mechanism) that can be independently attached and detached from the drafting unit, enabling quick conversions without permanent installation
Solution Approach 2:
The system transitions from static permanent installation to dynamic detachable mounting, allowing the compression device to be pivotably attached and detached from the drafting unit based on operational requirements
2Reliability
If a compression device is retrofitted to existing spinning machines, then high-quality yarn production is enabled, but the installation process becomes time-consuming and inflexible
Solution Approach 1:
The holder component is designed with universal mounting features that can accommodate different compression device types and configurations, enabling flexible retrofitting of existing spinning machines without requiring machine-specific custom installations
Solution Approach 2:
The retrofitting system is segmented into standardized components (holder, compression element, drive mechanism) that can be independently installed and configured, reducing installation complexity and increasing flexibility
3Reliability
If additional drive shafts and permanently installed drive connections are used, then the compression device can be reliably driven, but the device complexity and installation time increase
Solution Approach 1:
The drive mechanism is extracted from the permanent installation and integrated into the detachable holder system, allowing the compression device to be driven through the existing drafting unit drive shaft without requiring separate permanent drive connections
Solution Approach 2:
The holder combines multiple functions (mounting, drive transmission, positioning) into a single integrated component, reducing the number of separate drive shafts and connections needed while maintaining reliable drive transmission
