Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a standard speculum is used for visual examination, then the examination procedure is simple, but optimal illumination and proper optical magnification cannot be achieved
Solution Approach 1:
The patent combines multiple illumination sources (bright field, dark field, UV, IR, RGB) and optical elements into a single integrated speculum device. The image acquisition system merges these different lighting modes and optical components into one unified structure that can be inserted into the patient, thereby achieving optimal illumination and magnification without requiring multiple separate devices.
Solution Approach 2:
The speculum is designed with multi-functionality by incorporating various light sources (visible, UV, IR) and illumination modes (bright field, dark field) into a single device. This universal design allows the same speculum to perform multiple examination functions - standard visual examination, fluorescence examination, and other specialized imaging - thereby achieving optimal illumination quality across different examination types.
2Measurement precision
If multiple optical elements are integrated for high-resolution imaging, then image quality improves, but device complexity increases
Solution Approach 1:
The optical system is segmented into distinct functional modules - bright field illumination system, dark field illumination system, UV illumination system, IR illumination system, and imaging sensor - each performing a specific function. This segmentation allows for high-resolution imaging capabilities while managing complexity by organizing components into separate, manageable modules that can be independently optimized and maintained.
Solution Approach 2:
The patent incorporates a sliding mechanism that provides independent motion to each optical element, making the system dynamic rather than static. This allows the optical elements to be adjusted and repositioned as needed for different imaging modes and patient anatomies, achieving high-resolution imaging while maintaining operational flexibility that simplifies the overall system design.
3Adaptability or versatility
If independent motion control of optical elements is implemented, then imaging flexibility improves, but mechanical complexity increases
Solution Approach 1:
The patent replaces complex mechanical control systems with a more simplified sliding mechanism that provides independent motion to optical elements. Instead of using multiple motors and actuators for each optical element, the design employs a streamlined mechanical sliding system that achieves the same imaging flexibility with reduced mechanical complexity, making the device more reliable and easier to manufacture.
