Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation is used for laser treatment, then the practitioner can control the treatment process, but the accuracy and reliability of treatment decrease due to difficulty in maintaining concentration during long-term treatment
Solution Approach 1:
The patent replaces manual mechanical operation with an automated robot arm system that executes laser treatment based on pre-planned paths. The robot arm with end effector automatically positions and irradiates laser beams according to computer-generated trajectories, eliminating the need for continuous manual control while maintaining or improving treatment accuracy and reliability.
Solution Approach 2:
The patent changes the operational mode from manual control to automated control with precise parameter specification. Treatment parameters such as laser power, scanning speed, and path coordinates are predetermined and automatically executed, transforming the treatment process into a repeatable, high-precision automated operation that maintains consistency throughout long treatment sessions.
2Area of stationary object
If laser treatment is performed on curved surfaces like human face, then comprehensive coverage is achieved, but excessive movement of laser treatment apparatus causes vibration and reduced precision
Solution Approach 1:
The patent divides the treatment area into multiple discrete regions or segments that are processed sequentially. By breaking down the complex curved surface treatment into smaller manageable sections with predetermined paths, the system can maintain precise control and minimize unnecessary movement between regions, thereby reducing vibration while achieving comprehensive coverage.
Solution Approach 2:
The patent performs preliminary planning of the entire treatment path before actual laser irradiation. The robot arm follows pre-calculated trajectories that optimize movement efficiency and minimize vibrations. By preparing the complete path in advance based on the curved surface geometry, the system achieves comprehensive coverage while maintaining precision through optimized motion planning.
