Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate angle sensor and fixing tool (tripod) are used to allow observation of the target and light sources, then measurement accuracy of several μm to several tens of μm can be achieved, but the device complexity increases and handling becomes difficult
Solution Approach 1:
The imaging unit is integrated with the placement table into a single holding part, combining two previously separate components (angle sensor and placement table) into one unified structure. This merging eliminates the need for separate fixing tools while maintaining the capability to capture images of markers and measure coordinates with high precision.
2Measurement precision
If a tripod and fixing tool are prepared and used to fix the angle sensor, then high measurement accuracy can be achieved, but the loss of time increases due to preparation and adjustment procedures
Solution Approach 1:
The imaging unit is pre-integrated with the placement table in the device structure, so that the fixing and setup procedures are performed in advance during manufacturing. This preliminary integration eliminates the need for time-consuming setup procedures during actual measurement operations, allowing users to directly place targets and begin measurements.
3Adaptability or versatility
If the imaging unit and placement table are provided as separate bodies, then the device can be more flexible, but the ease of operation decreases due to complex handling procedures
Solution Approach 1:
The imaging unit and placement table are merged into a single integrated holding part, creating a unified structure that is easier to handle and operate. This integration maintains the adaptability of the device for different measurement tasks while significantly improving ease of operation by eliminating the need to separately position and fix multiple components.
