Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the object is held and rotated during beam irradiation, then processing efficiency and uniformity are improved, but misalignment between the object and beam axis occurs leading to reduced processing precision
Solution Approach 1:
The patent implements a feedback mechanism where the object measurement apparatus continuously measures the object's position and orientation during rotation, and the control apparatus adjusts the beam irradiation apparatus or rotation apparatus based on measured deviations from the desired alignment, thereby maintaining processing precision while enabling continuous rotation for improved productivity
Solution Approach 2:
The patent replaces mechanical alignment methods with optical measurement and control systems. The object measurement apparatus uses optical fields to detect object position and orientation, and the control apparatus uses computational algorithms to calculate and execute corrections, substituting complex mechanical adjustment mechanisms with a more precise and automated measurement-control system
2Manufacturing precision
If measurement apparatus is added to measure object and beam, then processing precision is improved, but device complexity increases
Solution Approach 1:
The patent designs the measurement apparatus to serve multiple functions: measuring object position, orientation, and shape, as well as measuring beam position and orientation. The control apparatus also performs multiple roles including calculating misalignment, determining correction amounts, and controlling both the beam irradiation apparatus and rotation apparatus. This multi-functionality reduces the need for separate dedicated components for each measurement and control task, thereby managing system complexity while achieving high processing precision
