Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional microscope equipment is used for testing, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses a camera to capture images of the specimen and then applies digital image processing and enhancement algorithms to create a magnified view. This copying approach replaces the need for complex optical magnification systems, achieving high magnification capability through software processing rather than hardware complexity.
Solution Approach 2:
The patent replaces the mechanical/optical microscope system with a camera-based imaging system combined with digital signal processing. Instead of using lenses and optical mechanisms to achieve magnification, the system captures the specimen image and processes it digitally, substituting mechanical complexity with computational methods.
2Measurement precision
If professional testing equipment is used, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically captures images of the specimen and performs digital enhancement without requiring manual operation of complex microscope controls. The automated image capture and processing makes the testing process accessible to non-experts while maintaining measurement precision through algorithmic enhancement.
Solution Approach 2:
The patent introduces a camera and digital processing system as an intermediary between the specimen and the observer. This intermediary captures the specimen image and applies enhancement algorithms, bridging the gap between simple imaging and high-precision observation, thereby improving ease of operation while maintaining measurement accuracy.
3Measurement precision
If high magnification equipment is used, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The system uses rapid sequential image capture followed by digital enhancement, performing the magnification process in discrete computational steps rather than requiring prolonged optical adjustment and observation. This periodic digital processing achieves high magnification quality faster than traditional microscope methods.
Solution Approach 2:
The system pre-processes the image by capturing it with the camera and applying enhancement algorithms before the user needs to observe the magnified specimen. This preliminary digital magnification eliminates the time required for manual microscope focusing and adjustment, providing immediate high-precision viewing.
