Method and system for automatic cutting of fabric
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for automatic cutting of fabric are laborious, imprecise, and prone to downtime due to the need for manual positioning and alignment of the fabric lay with respect to the cutting area, which can lead to safety issues and inefficiencies.
Innovation Solution
A system that uses marking spatial points on the fabric, detects these marks to determine the position and orientation, and automatically adjusts the cutting window for precise cutting, reducing the need for manual repositioning and minimizing downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual positioning and alignment of fabric lay is performed, then cutting precision can be maintained, but processing time increases and productivity decreases
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated vision system using cameras and image processing algorithms. The system automatically detects fabric edges, calculates alignment deviations, and guides the cutting head through software control, eliminating the need for manual measurement and positioning while maintaining cutting precision.
Solution Approach 2:
The system enables self-positioning by automatically detecting fabric characteristics through vision sensors and autonomously adjusting cutting parameters. The computer-controlled cutting head self-corrects its position based on real-time fabric detection, without requiring operator intervention for alignment.
2Measurement precision
If manual alignment checks are performed using laser beams, then fabric positioning accuracy improves, but processing downtime increases
Solution Approach 1:
The vision system operates continuously during the cutting process, constantly monitoring fabric position and making real-time adjustments. Unlike intermittent manual checks with laser beams, the automated system maintains continuous feedback and correction, eliminating stopping time while preserving positioning accuracy.
Solution Approach 2:
The patent replaces the manual laser alignment process with an automated vision-based measurement system. Multiple cameras capture fabric position data continuously, and computer algorithms process this information to maintain accurate positioning without requiring manual intervention or process interruption.
3Manufacturing precision
If operator performs manual fabric lay adjustment, then cutting window alignment improves, but job safety risks increase due to heavy loads
Solution Approach 1:
The system replaces manual fabric handling and positioning with automated mechanical systems. The computer-controlled cutting head and vision-guided positioning mechanism eliminate the need for operators to physically adjust heavy fabric lays, thereby maintaining alignment precision while removing safety hazards associated with manual handling of heavy materials.
