Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a reference scale is established on the target object beforehand for dimension measurement, then measurement accuracy can be ensured, but the operation complexity increases significantly
Solution Approach 1:
The measurement system automatically generates feature points on the target object using laser radiation and detects them through imaging, eliminating the need for manual reference scale establishment. The system performs self-measurement by autonomously creating and utilizing measurement features without requiring user intervention for reference setup.
Solution Approach 2:
The patent replaces the mechanical/manual process of establishing reference scales with an optical system that uses laser radiation and imaging to automatically create and detect feature points. This substitution of mechanical operations with optical fields enables automated measurement without manual reference scale placement.
2Reliability
If manual reference scale establishment is required for each measurement, then measurement reliability can be maintained, but the measurement time increases
Solution Approach 1:
The system pre-establishes feature points on the target object through laser radiation before actual dimension measurement begins. These pre-created feature points serve as automatic reference markers that eliminate the need for time-consuming manual reference scale establishment during each measurement operation.
Solution Approach 2:
The laser radiation continuously creates feature points on the target object, and the imaging system continuously detects these points, enabling uninterrupted automated measurement. This continuous operation eliminates the intermittent manual intervention required for reference scale establishment in traditional methods.
3Extent of automation
If feature points are formed using laser radiation, then automated measurement is enabled, but the device complexity increases
Solution Approach 1:
The imaging section serves multiple functions: it captures images of the target object, detects laser-formed feature points, and provides dimensional measurement data. This multi-functional design reduces the need for separate dedicated components for each measurement function, thereby limiting the increase in device complexity.
Solution Approach 2:
The laser beam acts as an intermediary that creates visible feature points on the target object, which then serve as reference markers for the imaging system. This intermediary approach enables automated measurement by bridging the gap between the measurement system and the target object without requiring complex direct measurement mechanisms.
