Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user manually sets inspection measurement items by understanding drawing instructions and adjusting observation conditions, then measurement accuracy can be achieved, but the operation complexity and time consumption increase significantly
Solution Approach 1:
The system automatically performs measurement item setting, observation condition adjustment, and measurement element association by itself. The automated adjustment section adjusts measurement conditions for each measurement element without user intervention, and the measurement control section automatically executes measurements based on reflected measurement positions and items from drawing data.
Solution Approach 2:
The system pre-processes drawing data to automatically extract measurement positions and measurement items before actual measurement execution. The drawing data is analyzed in advance to identify workpiece shapes, measurement elements, and their positions, preparing the measurement configuration beforehand without requiring manual setup during operation.
2Measurement precision
If the user manually associates imaging screens with measurement elements and adjusts measurement conditions for all elements, then accurate measurements can be obtained, but the setup time and procedural complexity increase
Solution Approach 1:
The automated adjustment section automatically adjusts measurement conditions for each measurement element without user intervention. The system self-configures the association between imaging screens and measurement elements by processing drawing data automatically, eliminating the manual setup process entirely.
Solution Approach 2:
The system performs preliminary processing of drawing data to automatically identify and configure measurement elements, their positions, and associated imaging parameters before actual measurement execution. This pre-configuration eliminates the need for time-consuming manual setup during operation.
3Measurement precision
If the system requires users to have specialized knowledge of CAD and measuring instruments, then precise measurement control can be achieved, but the accessibility and ease of use decrease
Solution Approach 1:
The system automatically performs all complex measurement control tasks including condition adjustment, element association, and measurement execution without requiring user expertise. The automated adjustment section handles technical adjustments autonomously, making the system accessible to users without specialized CAD or measuring instrument knowledge while maintaining precise measurement control.
4Ease of operation
If the system automatically matches workpiece shapes with drawing data and adjusts measurement conditions, then ease of operation improves, but the device complexity increases
Solution Approach 1:
The system automatically matches workpiece shapes with drawing data through automated image processing and pattern recognition algorithms. The measurement control section and automated adjustment section work together to self-configure measurement parameters, automatically adjust conditions for each measurement element, and execute measurements without user intervention, thereby improving ease of operation despite increased internal system complexity.
