Solution Overview
Problem
Existing methods for determining fiber material properties on textile machines are laborious and inefficient, particularly in monitoring yarn quality and identifying issues like fiber sliver breakage or incorrect fiber types, which can lead to poor productivity and equipment wear.
Innovation Solution
A method using load variables of electric drives at textile machine workstations to measure properties like thickness, tensile strength, and fiber type, allowing for real-time monitoring and control adjustments without additional sensors, by analyzing load angle and torque changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional methods are used to determine fiber material properties, then measurement precision can be achieved, but productivity decreases and loss of time increases
Solution Approach 1:
The drive system performs dual functions: it not only drives the treatment means but also simultaneously measures fiber material properties through its own load variable sensors. The drive system serves itself by using its existing components (current sensors, control electronics) to perform measurement functions without requiring separate dedicated measurement devices, thereby maintaining high measurement precision while avoiding productivity loss
Solution Approach 2:
The drive system is designed to perform multiple functions: mechanical driving of treatment means and simultaneous measurement of fiber material properties. By integrating measurement capabilities into the drive system, the patent achieves multi-functionality that resolves the contradiction between measurement precision and productivity
2Measurement precision
If traditional property determination methods are used, then measurement precision is maintained, but loss of time increases
Solution Approach 1:
The measurement process continues uninterrupted during normal textile machine operation. The drive system continuously monitors load variables as fiber material passes through treatment means, eliminating the need to stop production for quality measurements. This continuous measurement approach maintains measurement precision while eliminating time loss associated with traditional batch testing methods
Solution Approach 2:
The drive system performs measurement functions simultaneously with its driving function, allowing quality determination to occur during production rather than requiring separate measurement time. The system serves dual purposes without requiring additional time resources
3Measurement precision
If additional sensors are installed to measure fiber material properties, then measurement precision improves, but device complexity increases
Solution Approach 1:
The drive system uses its own existing sensors and control electronics to perform measurement functions. Instead of adding separate sensors, the system leverages its inherent capability to monitor its own operational parameters (current, torque) to infer fiber material properties, thereby avoiding increased device complexity
Solution Approach 2:
The drive system is designed to perform multiple functions with a single integrated design. By making the drive system universal (both driving and measuring), the patent avoids adding separate dedicated measurement devices, thus maintaining low device complexity while achieving high measurement precision
4Productivity
If real-time property monitoring is implemented, then productivity improves, but device complexity increases
Solution Approach 1:
The drive system performs real-time measurement of fiber material properties using its own load variable sensors and control electronics. By making the drive system self-sufficient for both driving and measuring, the patent achieves real-time monitoring capability without requiring separate complex monitoring infrastructure
Solution Approach 2:
The drive system is designed as a universal component that handles both mechanical driving and real-time measurement functions. This multi-functionality enables real-time property monitoring while avoiding the need for additional dedicated monitoring devices that would increase system complexity
