Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a processing beam irradiates an object from a single direction to form boundary parts, then the processing speed is improved, but the manufacturing precision of the boundary parts deteriorates
Solution Approach 1:
The patent applies multi-directional irradiation by changing the irradiation direction from a single direction to multiple directions (first direction and second direction). This dimensional change in the irradiation approach allows forming boundary parts with higher precision while maintaining processing efficiency, resolving the contradiction between processing speed and boundary part precision.
2Manufacturing precision
If the processing beam irradiates the object multiple times from different directions to form multiple boundary parts, then the manufacturing precision is improved, but the loss of time increases
Solution Approach 1:
The patent combines multiple boundary part formation processes into a single integrated processing sequence. By forming multiple boundary parts (first boundary part and second boundary part) through coordinated multi-directional irradiation within one processing cycle, the system achieves high separation precision without proportionally increasing processing time, thus resolving the contradiction between separation precision and processing time.
3Reliability
If the processing beam forms deep grooves in the object, then the separation effectiveness is improved, but the measurement precision of groove depth deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the processing beam forms grooves and the system measures the groove depth, using the measurement results to adjust subsequent processing. This closed-loop feedback control ensures that even deep grooves are formed with accurate depth control, resolving the contradiction between separation effectiveness and groove depth measurement precision.

AI summary
A processing method includes: forming a first boundary part of a plurality of boundary parts, which are for separating a first part of an object and a second part of the object, by irradiating the object with a processing beam from a first direction relative to the object; and forming a second boundary part of the plurality of boundary parts by irradiating the object with the processing beam from a second direction different from the first direction relative to the object.
