Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a gantry structure with laser cutting head is used to cut thick aluminum foil, then the cutting capability for thick materials is improved, but the working efficiency decreases significantly compared to galvanometer cutting
Solution Approach 1:
The patent divides the cutting system into multiple independent laser cutting heads (first laser cutting head and second laser cutting head) that can operate simultaneously on different sections of the aluminum foil. This segmentation allows parallel processing, significantly improving productivity while maintaining the ability to handle thick materials that require gantry-based cutting capability.
2Productivity
If multiple laser cutting heads are used to improve working efficiency, then the processing speed increases, but the device complexity increases
Solution Approach 1:
The patent merges multiple laser cutting heads onto a single gantry structure that shares common motion control systems, guide rails, and support mechanisms. This combining approach allows parallel cutting operations to improve productivity while avoiding the full complexity of multiple independent gantry systems, as the shared infrastructure reduces overall system complexity.
3Manufacturing precision
If the gantry structure is made more robust to ensure cutting precision, then the manufacturing precision is improved, but the weight of the structure increases
Solution Approach 1:
The patent employs composite material construction for the gantry structure, combining materials with high strength-to-weight ratios. This allows the structure to maintain the robustness and rigidity needed for precise cutting of thick aluminum foil while minimizing the overall weight, thereby improving dynamic performance and positioning accuracy without sacrificing structural integrity.
