Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual focus adjustment is used for repositioned articulated microscope, then focus accuracy can be maintained, but time consumption and operational complexity increase significantly
Solution Approach 1:
The system pre-calculates and stores focus position information corresponding to different workspace positions before actual observation. When the articulated microscope is repositioned, the pre-stored focus data is retrieved and applied automatically, eliminating the need for time-consuming manual focus adjustment while maintaining accuracy.
Solution Approach 2:
The system continuously monitors the position of the articulated microscope through sensors and automatically adjusts focus based on real-time position feedback. This closed-loop control ensures focus accuracy is maintained during repositioning without requiring manual intervention, thereby reducing time consumption.
2Measurement precision
If manual focus adjustment is used during repositioning, then focus control can be precise, but ease of operation deteriorates due to frequent manual interventions
Solution Approach 1:
The autofocus system enables the articulated microscope to automatically adjust focus based on its own position information without requiring manual intervention. The system self-regulates focus control precision through integrated sensors and control algorithms, significantly improving ease of operation while maintaining precise focus control.
Solution Approach 2:
The system replaces manual mechanical focus adjustment with an automated electronic autofocus mechanism. Sensors detect position changes and trigger electronic control of the focus mechanism, substituting manual operation with automated systems that maintain precision while dramatically improving ease of operation.
3Productivity
If autofocus based on positional information is implemented, then productivity increases through faster focus adjustment, but device complexity increases due to additional sensors and control systems
Solution Approach 1:
The articulated microscope's position sensors serve dual purposes: they track the microscope's spatial position for flexible positioning and simultaneously provide positional information for autofocus control. This multi-functionality enables fast focus adjustment without adding dedicated sensors, thereby improving productivity while minimizing the increase in device complexity.
Solution Approach 2:
The system merges the position detection function with the focus control function by utilizing the existing articulated arm position information for both positioning and autofocus purposes. This integration eliminates the need for separate focus detection mechanisms, achieving fast focus adjustment while keeping device complexity manageable through functional consolidation.
Data Source
AI summary
An articulated microscope is configured to be mounted in a first position, obtain information that the articulated microscope has been moved from the first position to a second position, and adjust a focus of the articulated microscope to observe an object based on the information that the articulated microscope has been moved to the second position.
