Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If users manually adjust laser power parameters to create perforations, then they can achieve cutting or incision effects, but they must perform multiple trial and error attempts to find optimal settings for different materials and thicknesses
Solution Approach 1:
The control unit automatically determines optimal laser power parameters for perforation before the actual laser processing begins. The system pre-calculates and sets the appropriate power curve based on the selected material type and thickness, eliminating the need for users to perform multiple trial and error attempts during the processing stage.
Solution Approach 2:
The system performs self-adjustment of laser power parameters automatically. When a user selects a material type and thickness, the control unit autonomously selects and applies the appropriate power curve without requiring manual intervention or repeated adjustments by the user.
2Adaptability or versatility
If users manually select and adjust power curves for different materials, then they can adapt to varying material properties, but the operation becomes complex and requires significant user experience
Solution Approach 1:
The control unit automatically adapts the laser power settings to the selected material type and thickness. The system performs self-adjustment by autonomously selecting the appropriate power curve from its database, eliminating the need for users to manually adjust parameters or rely on their experience and knowledge of material properties.
Solution Approach 2:
The system automatically changes the laser power parameters based on the selected material characteristics. The control unit selects from multiple predefined power curves with different characteristics (continuous, pulsed, modulated) and applies the appropriate parameters automatically when material type and thickness are specified, enabling easy adaptation to different materials without complex manual adjustments.
3Adaptability or versatility
If multiple power curves are stored for different perforation types, then users can select from various perforation shapes and patterns, but the device complexity increases
Solution Approach 1:
The control unit automatically manages the selection and application of appropriate power curves from its database. When a user specifies material type and thickness, the system autonomously determines and applies the most suitable power curve without requiring the user to understand or manually configure the complex parameters, thereby maintaining simplicity in operation despite the sophisticated control capabilities.

AI summary
A laser device and a method for producing a perforation on a workpiece for various laser devices is disclosed. Two beam sources in the form of lasers may be located to act on the workpiece to be processed. The workpiece is deposited in a defined manner on a processing table and a laser beam emitted by the beam source is deflected in the direction of the workpiece and focused for processing. Control is effected via software running in a control unit where the workpiece is processed by adjusting a carriage in the X-Y direction or by adjusting an angle of a mirror. A “perforation” option may be loaded or used such that during processing of the workpiece, a continuous line or incision is formed on an upper side of the workpiece over a defined depth, and indentations or cuts are formed at defined intervals.
