Engineering Contradiction Analysis
1Productivity
If a laser beam is irradiated in a stationary or linear manner focusing energy on a point or continuously in one direction, then processing quality at a precise level is maintained, but the ability to perform simultaneous laser scanning or processing of a specific space is limited
Solution Approach 1:
The patent transforms the traditional point-by-point or linear laser processing into three-dimensional space processing by using a rotating mirror unit that scans the laser beam across a volumetric region. This dimensional expansion allows simultaneous processing of multiple targets in space while maintaining precision through controlled beam scanning patterns and focal point management.
Solution Approach 2:
The patent introduces dynamic elements including a rotating mirror unit that continuously scans the laser beam, adjustable focal lengths, and variable irradiation distances. These dynamic capabilities enable the system to adapt to different processing requirements and simultaneously engage multiple targets throughout a three-dimensional space while maintaining precise energy delivery to each target location.
2Area of stationary object
If the laser beam is focused on a single point or irradiated in one direction, then energy density is concentrated, but the irradiation area is limited and cannot cover a three-dimensional space
Solution Approach 1:
The patent segments the irradiation process into multiple focal points distributed throughout three-dimensional space. The rotating mirror unit divides the continuous laser beam into discrete scanning positions, each maintaining high energy density, while collectively covering a large volumetric area. This segmentation allows the system to achieve both broad coverage and concentrated energy delivery simultaneously.
Solution Approach 2:
The patent employs variable parameters including adjustable focal lengths, changing irradiation distances, and variable scan angles of the rotating mirror unit. These parameter changes enable dynamic adjustment of the irradiation area size and shape while maintaining appropriate energy density levels across different spatial regions, allowing optimization for different operational requirements.
3Adaptability or versatility
If the focal length is fixed, then the laser processing setup is simple, but the distance at which the laser beam irradiation area is located cannot be adjusted
Solution Approach 1:
The patent implements a multi-functional optical system where a single apparatus can operate at multiple focal lengths and irradiation distances. The rotating mirror unit combined with adjustable optical elements provides universal capability to process targets at varying distances and angles, replacing the need for multiple fixed-focus systems and reducing overall system complexity through integrated functionality.
