Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple sensor arrays are arranged to cover large-area samples, then the field view is improved, but the device complexity increases
Solution Approach 1:
The sensor system is divided into multiple sensor arrays (first sensor array and second sensor array) with overlapping active areas. Each sensor array captures a portion of the large-area sample, and the overlapping regions ensure complete coverage without gaps. This segmentation allows the system to maintain a large field view while managing complexity through modular sensor placement.
2Area of stationary object
If sensors are moved to capture large-area samples, then the field view is improved, but the measurement precision deteriorates
Solution Approach 1:
The sensor arrays are pre-positioned with overlapping active areas before sample analysis begins. This preliminary arrangement ensures that all regions of the large-area sample, including fine details in overlapping zones, are captured with high precision from multiple perspectives. The overlapping configuration allows for potential image fusion or validation, maintaining measurement precision across the entire field view.
3Measurement precision
If conventional optical microscope is used to detect fine differences in sample media, then the measurement precision is improved, but the device complexity increases due to multiple lenses and dyeing procedures
Solution Approach 1:
The invention extracts and eliminates the dyeing step from the conventional optical microscope workflow. By using sensor arrays with overlapping active areas that can directly detect fine differences in sample media through their spatial resolution and signal processing capabilities, the system removes the need for additional dyeing procedures and multiple magnification lenses, thereby reducing device complexity while maintaining measurement precision.
