Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical systems for shaping laser beams are not capable of displaying both line-shaped and spot-shaped laser marks, limiting their ability to transfer angles between target surfaces.
Innovation Solution
Incorporating additional optical elements that shape the ring-shaped laser beam into a plane parallel or perpendicular to the propagation plane, allowing for the generation of spot-shaped laser marks alongside line-shaped marks, and integrating these elements into the existing optical system during manufacturing to reduce alignment efforts and requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the optical system uses only a conical mirror to shape the laser beam, then a line-shaped laser mark is generated, but the system cannot generate spot-shaped laser marks for angle transfer
Solution Approach 1:
The patent applies multi-functionality by enabling the optical system to generate both line-shaped and spot-shaped laser marks using a unified optical configuration. The conical mirror is designed with specific geometric parameters (cone angle, aperture ratio) that allow it to perform multiple functions: generating line-shaped marks when illuminated directly and spot-shaped marks when illuminated at specific angles, thereby eliminating the need for separate optical systems for different marking tasks.
Solution Approach 2:
The patent utilizes parameter changes by varying the illumination angle and position of the laser beam on the conical mirror to achieve different output beam shapes. By adjusting the incident beam parameters (angle of incidence, radial position on the mirror surface), the system can transform a single optical element into a multi-functional device that produces both line and spot patterns, resolving the contradiction between versatility and complexity.
2Adaptability or versatility
If additional optical elements are added to generate spot-shaped laser marks, then angle transfer capability is improved, but alignment effort and complexity increase
Solution Approach 1:
The conical mirror is designed as a universal optical element that can generate both line-shaped and spot-shaped laser marks through varying illumination conditions. This multi-functionality eliminates the need for additional separate optical elements dedicated to spot generation, thereby maintaining angle transfer capability while avoiding the alignment complexity that would arise from adding more components.
Solution Approach 2:
The patent merges the functions of line generation and spot generation into a single optical element (the conical mirror). By combining multiple functionalities into one component, the system achieves angle transfer capability without requiring separate optical mounts or additional alignment procedures, thus improving ease of operation while maintaining versatility.
