Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional work table is used for laser processing, then the substrate can be processed, but the work table becomes contaminated with fine particles and fumes that are not effectively collected
Solution Approach 1:
The work table surface is segmented into multiple cell regions separated by groove regions, with suction holes strategically positioned in the groove regions to collect particles at their generation points, preventing widespread contamination
Solution Approach 2:
A suction system acts as an intermediary between the laser processing zone and the work table surface, capturing particles and fumes through suction holes and exhaust ports before they can contaminate the work table
2Reliability
If vacuum pressure is applied to fix the substrate, then the substrate is securely held, but particles and fumes are generated during cutting that contaminate the work area
Solution Approach 1:
The substrate fixation function and particle collection function are merged into a single work table structure, where the same vacuum system that secures the substrate also facilitates particle removal through integrated suction holes and exhaust pathways
Solution Approach 2:
The vacuum pressure used to fix the substrate is converted into a beneficial force for particle removal, where the same pressure differential that holds the substrate in place also drives particles through suction holes to the exhaust system
