Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If drawing data intake and coordinate setting are required for measurement, then measurement precision is improved, but ease of operation deteriorates due to requiring specialized CAD knowledge
Solution Approach 1:
The patent displays a copy of the drawing data (workpiece shape from DXF file) overlaid on the captured workpiece image. This visual copy allows users to see the relationship between the drawing and actual workpiece without needing to understand CAD coordinate systems, eliminating the need for specialized knowledge while maintaining measurement accuracy.
Solution Approach 2:
The patent introduces an intermediary visual display that shows both the captured workpiece image and the drawing data superimposed together. This intermediary representation acts as a bridge between the complex CAD coordinate system and the user interface, allowing users to perform measurements by visual alignment rather than coordinate manipulation.
2Measurement precision
If coordinate setting and positioning between workpiece image and drawing data are performed, then measurement accuracy is improved, but device complexity increases due to multiple processing sections
Solution Approach 1:
The patent merges the display of the captured workpiece image and the drawing data into a single unified display screen. By combining these two elements visually, the system eliminates the need for separate processing stages for coordinate setting and positioning, reducing overall system complexity while maintaining measurement accuracy.
3Ease of operation
If visual association display is implemented, then ease of operation is improved, but loss of information increases due to overlaying multiple data layers
Solution Approach 1:
The patent applies local quality by selectively displaying different visual information in different regions or layers of the display. The drawing data and workpiece image are overlaid with different visual characteristics, allowing users to distinguish between them while maintaining access to both data types simultaneously, thus preventing information loss.

AI summary
A user can easily perform desired measurement without having specialized knowledge of CAD or a measuring instrument. An image measurement apparatus 1 includes an epi-illumination section 13a and a transmitted illumination section 13b, a drawing intake section 111 that selectively takes in drawing data in accordance with an intake instruction, a display screen generation section 115 that generates a display screen on which a workpiece shape included in the drawing data taken in by the drawing intake section 111 and a workpiece representation included in an image generated by the imaging section 15 are displayed in visual association with each other, and an associating section that associates measurement setting data or a measurement result with the workpiece representation visually associated with the workpiece shape included in the drawing data on the display screen generated by the display screen generation section 115.
