Textile Machine LED Illumination for Shaded Yarn Defect Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Textile machines, such as automatic winders, face challenges in operator visibility and workability due to shaded areas around yarn processing devices, making it difficult to detect and remove defects like entangled yarn, especially when these areas are poorly illuminated.
Innovation Solution
Incorporating an illuminating section, preferably LED lights, that illuminates the areas requiring operator attention from the outer side, directing light towards shaded spaces between unit frames and yarn storage devices, and activating only when defects are detected to improve visibility and reduce energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If warning lamps and green lamps are attached to indicate defect locations, then the operator can understand the occurrence of defect and the area, but the area requiring operator work remains poorly illuminated and visibility is insufficient
Solution Approach 1:
The patent transitions from two-dimensional indicator lamps (front side and upper part) to three-dimensional illumination by placing light sources at multiple spatial positions (upper side, lower side, and side surfaces) to illuminate the work area from multiple angles, solving the visibility problem in shaded regions
Solution Approach 2:
The patent introduces reflective members (reflectors) as intermediaries to redirect and distribute light from the light sources to the work area, enhancing illumination efficiency and ensuring adequate visibility in difficult-to-reach shaded regions
2Illumination intensity
If multiple light sources are positioned at upper side, lower side, and side surfaces to illuminate shaded areas, then visibility of work area is improved, but device complexity increases
Solution Approach 1:
The illumination system is segmented into multiple independent light sources positioned at different locations (upper side, lower side, side surfaces), allowing each segment to illuminate specific shaded areas independently, thereby improving overall visibility while maintaining modular simplicity
Solution Approach 2:
The illumination system is designed to serve multiple functions simultaneously: indicating defect locations, illuminating work areas from multiple angles, and providing adequate visibility in shaded regions, thereby justifying the increased structural complexity through enhanced multi-functionality
3Use of energy by stationary object
If LED lights are used to illuminate defect areas, then energy consumption is reduced and lifespan is extended, but illumination coverage may be insufficient without multiple positions
Solution Approach 1:
The patent expands illumination coverage by positioning LED light sources in three-dimensional space (upper side, lower side, side surfaces) rather than a single location, allowing comprehensive coverage of shaded work areas while maintaining the energy efficiency of LED technology
Solution Approach 2:
Reflective members are introduced as intermediaries to redirect and distribute LED light to difficult-to-reach areas, maximizing the illumination coverage of energy-efficient LED sources without requiring additional high-power light sources

AI summary
A textile machine (automatic winder) includes a plurality of winding units (2). Each of the winding units (2) includes a unit frame (6), and an LED lamp (71) is attached to the unit frame (6). For example, when a defect occurs in a yarn storage device (5) or the like, that is, when work of an operator is required, the LED lamp (71) illuminates the yarn storage device (5) to improve workability of the work for the operator.
