Solution Overview
Problem
Existing processing systems face challenges in efficiently and precisely processing objects using laser light, particularly in forming and moving irradiation areas to achieve desired patterns or modifications on the object's surface.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single beam movement apparatus is used to move multiple processing beams, then the system structure is simplified, but it becomes difficult to independently control the movement routes of each beam
Solution Approach 1:
The beam movement apparatus is divided into multiple independent sub-apparatuses, each responsible for controlling a specific processing beam. This segmentation allows each beam to have its own independent movement control while maintaining an overall coordinated system, resolving the contradiction between structural simplicity and independent control capability.
2Adaptability or versatility
If multiple beam movement apparatuses are used to independently control each processing beam, then independent control is achieved, but the system structure becomes complex
Solution Approach 1:
Multiple beam movement apparatuses are integrated into a unified control system with coordinated operation. The apparatuses share common control logic and synchronization mechanisms, merging their functions to achieve independent beam control while avoiding the complexity of completely separate systems.
3Ease of operation
If processing beams are moved along fixed predetermined routes, then the control system is simple, but the system lacks flexibility to adapt to different processing patterns
Solution Approach 1:
The beam movement routes are made dynamically adjustable rather than fixed. The control system can modify movement parameters and routes in real-time based on different processing requirements, allowing the system to adapt to various processing patterns while maintaining ease of operation through automated control.
4Ease of operation
If the arrangement direction of irradiation areas is fixed, then the system is easier to control, but it cannot accommodate complex pattern requirements
Solution Approach 1:
The system adds rotational degree of freedom to the beam movement control, allowing irradiation areas to be arranged not only along linear paths but also in rotational patterns. This dimensional enhancement enables complex pattern formation while maintaining control through coordinated angular and linear movements.
