Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If conventional filtration media are used, then filtration function is provided, but frequent replacement is required leading to increased costs and waste processing issues
Solution Approach 1:
The patent replaces conventional mechanical filtration media with a laser-cut filtration tube system. High-power laser beams precisely cut patterns into tubular structures, creating filtration elements with controlled pore distributions that extend service life and reduce waste from frequent replacements
2Productivity
If existing laser cutting systems are used, then cutting capability is provided, but efficiency and precision in cutting micro slots, holes, and pores in tubes is insufficient
Solution Approach 1:
The patent employs high-power laser beams with precisely controlled parameters (power, pulse duration, focal point) to cut micro slots, holes, and pores in tubes. The laser parameters are optimized to achieve both high cutting efficiency and precise pore formation, resolving the contradiction between productivity and manufacturing precision
Solution Approach 2:
The patent uses pulsed laser cutting with synchronized rotational and linear stage motion. The periodic pulsing of the laser combined with coordinated movement enables precise control over pore formation while maintaining high cutting efficiency through continuous processing
3Manufacturing precision
If laser cutting is performed without synchronized motion control, then cutting operation is simplified, but precision in creating filtration patterns is compromised
Solution Approach 1:
The patent implements synchronized motion control where the laser pulsing is feedback-controlled based on the rotational and linear position of the tube. This coordination ensures precise pore placement and pattern accuracy while managing system complexity through integrated control

AI summary
A laser cutting system for cutting articles, such as tubes, and method of using the same. The laser cutting system can cut slots, holes, and/or pores into each article or tube to form filtration tubes, for example. The system includes a delivery system for delivering a laser beam from a laser source, at least one mirror, a focusing objective lens, a gas source, and a delivery nozzle. A first stage holds each article in a longitudinal direction, and may rotate the article axially during delivery of the gas and laser beam towards the article and move the article longitudinally relative to the delivery nozzle. A second stage is provided in the system for moving the delivery nozzle relative to the article being held by the first stage. A controller controls actuation of the laser beam and the gas source, and movement of the first stage and the second stage.
