Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a standard speculum with visual examination is used, then the device complexity is low and ease of operation is high, but the measurement precision and detection accuracy are insufficient
Solution Approach 1:
The patent merges the speculum with an integrated optical imaging system, combining illumination sources, lenses, and sensors into a single integrated device. This allows the speculum to provide both mechanical examination functions and high-precision optical detection, resolving the contradiction between detection accuracy and device complexity.
Solution Approach 2:
The speculum is designed to perform multiple functions: mechanical examination, optical illumination, image capture, and real-time visualization. This multi-functional design enables the device to achieve high detection precision while maintaining operational efficiency, as the same device structure serves multiple diagnostic purposes.
2Illumination intensity
If standard visual examination is used, then the ease of operation is high, but the illumination intensity and optical magnification are insufficient for detecting abnormal cells
Solution Approach 1:
The optical system is pre-configured within the speculum with fixed illumination paths and focused optical components. The illumination sources are pre-positioned to provide optimal lighting angles, and the imaging system is pre-calibrated, eliminating the need for complex real-time adjustments during operation.
Solution Approach 2:
The integrated optical system automatically provides appropriate illumination and magnification without requiring manual intervention. The system self-regulates illumination intensity and optical focus, making the device as easy to operate as a standard speculum while delivering superior imaging capabilities.
3Measurement precision
If no optical magnification is used, then the device complexity is low, but the detection precision for abnormal cells is insufficient
Solution Approach 1:
The optical imaging system is nested within the speculum structure, with lenses, sensors, and illumination components compactly arranged inside the speculum housing. This nested design provides high-magnification optical detection capabilities while maintaining a compact, clinically practical device size that does not significantly increase operational complexity.

AI summary
A system for direct imaging and diagnosing of abnormal cells in a target tissue includes a disposable optical speculum and an image acquisition system having the speculum assembled on and mechanically secured thereto. The image acquisition system is arranged to capture at least one of a single image or multiple images or video of cells within the target tissue using at least one of bright field or dark field ring illumination divided into independently operated segments to obtain a plurality of data sets. An image analysis and control unit in communication with the image acquisition system analyzes the data sets and applies algorithms to the data sets for diagnosing abnormal cells.
