Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the equipment structure is changed to accommodate different processing targets, then the processing versatility is improved, but the device complexity and adjustment time increase
Solution Approach 1:
The patent applies universality by designing a single laser processing apparatus that can handle multiple processing targets and patterns through software control. The system uses a beam splitter to divide laser beams and independently control multiple beams to process different areas simultaneously, eliminating the need for dedicated equipment for each processing type. This multi-functional approach allows one apparatus to perform various laser processing tasks that would traditionally require separate specialized devices.
Solution Approach 2:
The patent applies segmentation by dividing the laser beam into multiple separate beams using a beam splitter. Each beam can be independently directed to different processing areas on the target material. This segmentation allows simultaneous processing of multiple locations with different parameters, providing versatility without requiring multiple complete laser systems, thus reducing overall device complexity while maintaining adaptability.
2Adaptability or versatility
If the equipment structure is changed to accommodate different processing targets, then the processing versatility is improved, but the adjustment time and potential for errors increase
Solution Approach 1:
The patent applies dynamics by implementing software-controlled, dynamically adjustable laser beam paths and processing parameters. Instead of physically reconfiguring equipment for different tasks, the system allows real-time dynamic adjustment of beam directions, focal points, and processing parameters through computer control. This enables rapid switching between different processing targets and patterns without mechanical adjustments, significantly reducing setup time while maintaining versatility.
Solution Approach 2:
The patent replaces mechanical adjustment systems with software-based control mechanisms. Rather than physically moving mirrors, lenses, or other optical components to adapt to different processing targets, the system uses computational methods to control beam paths and processing parameters. This substitution eliminates time-consuming manual adjustments and reduces the risk of alignment errors while preserving the ability to process various targets.
3Adaptability or versatility
If complex optical element replacements are performed, then the processing capability is improved, but the costs and potential for errors increase
Solution Approach 1:
The patent applies copying by using a beam splitter to create multiple copies of the original laser beam. These copied beams can be independently directed to different processing areas, enabling simultaneous multi-location processing. This approach provides enhanced processing capability without requiring multiple complete laser systems or complex optical element replacements, thereby reducing costs while maintaining versatility.
Solution Approach 2:
The patent implements universality through a single laser source that serves multiple processing functions simultaneously. By using software control and beam splitting, one laser apparatus can perform various processing tasks on different materials and patterns without requiring specialized optical elements for each application. This reduces the need for expensive optical element replacements while maintaining diverse processing capabilities.
