Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cutting methods are used to fit images on label sheets, then cutting can be performed, but numerous trials for alignment and size adjustments are required, increasing user expenses, job time, and environmental impact
Solution Approach 1:
The patent replaces conventional mechanical cutting methods with laser beam cutting. The laser cutting unit irradiates the sheet with a laser beam to cut along the sheet conveying path or on the post-processing tray, eliminating the need for mechanical alignment trials and cutting tools, thereby achieving precise cutting without increasing job time or expenses
Solution Approach 2:
The control unit can arbitrarily change laser power of the laser cutting unit, allowing flexible adjustment of cutting depth and intensity. This enables precise control over the cutting process to achieve accurate label separation without requiring multiple trial runs, reducing both time and material waste
2Manufacturing precision
If conventional cutting methods are used, then cutting can be performed, but various trials for correcting imbalance between label size and character size are required, increasing user expenses and environmental load
Solution Approach 1:
The laser cutting system replaces mechanical cutting with optical energy-based cutting, allowing precise control of cut depth and position through software control. This eliminates material waste from failed cutting attempts and enables accurate label size adjustment without physical trial-and-error
Solution Approach 2:
The control unit can cause the laser cutting unit to cut only the label part of the label sheet or to cut in a perforating manner rather than completely through. This partial cutting action allows flexible label separation without wasting material and enables correction of size imbalances without requiring complete re-cutting
3Productivity
If conventional cutting methods are used, then cutting can be performed, but numerous trials are required, increasing user expenses
Solution Approach 1:
The laser cutting unit with programmable control replaces complex mechanical cutting setups, allowing rapid reconfiguration of cutting patterns through software rather than physical tool changes. This dramatically improves productivity while maintaining ease of manufacture through digital control
Solution Approach 2:
The system provides dynamic control over cutting parameters including laser power, cutting depth, and cutting pattern. The control unit can adapt cutting parameters in real-time based on the specific label requirements, enabling high productivity with simple operation through automated adjustment
