Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed wavelength settings are used for illumination, then device complexity is reduced and ease of operation is improved, but adaptability to different diagnosis purposes deteriorates and measurement precision of lesion features worsens
Solution Approach 1:
The system dynamically adjusts the light quantity ratios of multiple light sources based on the selected diagnosis purpose. The light source control unit changes the illumination characteristics in real-time according to different diagnostic needs (e.g., screening, close inspection, disease type, disease stage), transforming a static illumination system into a dynamic one that adapts to various observation conditions.
Solution Approach 2:
The system changes the parameters of illumination light by adjusting the light quantity ratios of multiple light sources with different wavelengths. By modifying the spectral composition and intensity distribution of the illumination light according to different diagnosis purposes, the system optimizes the visibility of specific lesion features for each diagnostic scenario.
2Device complexity
If fixed wavelength settings are used for illumination, then device complexity is reduced, but adaptability to different diagnosis purposes and measurement precision of lesion features worsen
Solution Approach 1:
The illumination system is segmented into multiple independent light sources, each emitting light at different wavelengths. This segmentation allows the system to selectively control the contribution of each wavelength component to the overall illumination, enabling adaptability to different diagnosis purposes while maintaining a modular and manageable device structure.
Solution Approach 2:
The system achieves multi-functionality by using a set of light sources with different wavelengths that can be combined in various ratios to serve multiple diagnostic purposes. The same physical infrastructure (light sources, control unit) supports diverse diagnostic scenarios including screening, close inspection, different disease types, and different disease stages, making the device universally applicable.
3Device complexity
If fixed wavelength settings are used for illumination, then device complexity is reduced, but measurement precision of lesion features and diagnostic accuracy worsen
Solution Approach 1:
The system optimizes measurement precision by changing the spectral parameters of illumination light according to different diagnosis purposes. By adjusting the light quantity ratios to emphasize specific wavelengths that highlight particular lesion features (e.g., vascular patterns, surface structures), the system enhances the contrast and visibility of diagnostically relevant features, thereby improving measurement precision without excessive complexity.
4Adaptability or versatility
If multiple light sources with different wavelengths are used, then adaptability to different diagnosis purposes is improved, but device complexity increases
Solution Approach 1:
The system merges multiple light sources with different wavelengths into a unified illumination system controlled by a single light source control unit. This consolidation allows the system to achieve high adaptability through coordinated control of multiple sources while managing device complexity by integrating the control functions into a centralized unit that selects and adjusts light quantity ratios based on diagnosis purpose.
