Innovation Solution
A laser machine equipped with a camera and image processing module that identifies and calculates the position and angle of the textile, adjusts laser instructions, and performs quality control using image recognition software and 3D scanning, allowing for automatic marking and precise positioning without manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a light projector is used to guide garment placement, then the marking area can be defined, but the garment placement precision deteriorates due to creases and irregularities
Solution Approach 1:
The patent replaces the mechanical light projector guidance system with an optical recognition system (camera 102, 103) that automatically detects garment position and contours. The control unit 51 processes images to identify garment placement and adjusts laser instructions accordingly, eliminating the need for manual alignment with projected guides.
Solution Approach 2:
The system enables self-service by allowing the garment to be placed naturally without precise manual positioning. The camera captures the actual garment position, the control unit analyzes the image to determine placement accuracy, and automatically adjusts the laser marking instructions to compensate for any deviations, making the system adapt to the garment rather than requiring the garment to conform to a fixed template.
2Manufacturing precision
If manual adjustment of garment position is performed, then placement accuracy can be improved, but the processing time increases
Solution Approach 1:
The system performs preliminary action by capturing an image of the garment placement before the laser marking begins. The control unit 51 processes this image to determine the actual garment position and calculates the necessary adjustments to the laser instructions in advance, so that when the laser starts marking, the corrected path is already prepared, eliminating any delay during the marking process.
Solution Approach 2:
The system implements feedback by using the camera 102, 103 to continuously monitor garment placement and providing this information to the control unit 51. The control unit compares the actual placement with the intended placement and automatically adjusts the laser marking instructions based on this feedback, ensuring high precision without requiring manual intervention or slowing down the process.
3Manufacturing precision
If the system adapts to each garment's unique position and dimensions, then marking accuracy improves, but the device complexity increases
Solution Approach 1:
The system achieves universality by designing a single integrated setup that handles multiple functions: the camera 102, 103 serves both to capture garment placement and to measure focal distance; the control unit 51 performs both image processing and laser instruction adjustment; the same hardware configuration works for different garment types, sizes, and materials without requiring physical reconfiguration, reducing overall system complexity despite the sophisticated processing.
Solution Approach 2:
The patent merges multiple functions into unified components. The camera system simultaneously performs garment recognition, position detection, and focal distance measurement. The control unit integrates image processing, position calculation, and laser parameter adjustment in a single processing chain. This consolidation reduces the number of separate devices and interfaces needed, simplifying the overall system while maintaining high marking accuracy.
