Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional lighting systems are used for microscopes, then the system structure is simple, but the illumination intensity and stability are insufficient
Solution Approach 1:
The lighting system is divided into separate functional modules: solid state light engine, light guide, and adjustable collimator. This segmentation allows each component to be optimized independently for performance while maintaining overall system manageability
Solution Approach 2:
The adjustable collimator is designed to be universally compatible with various microscopes and light guides, providing multiple functions including focal distance adjustment, illumination area control, and beam shaping, thereby reducing the need for multiple specialized components
2Ease of manufacture
If conventional lighting systems are used, then the device is easy to manufacture, but the cost-effectiveness and spectral quality are poor
Solution Approach 1:
The system uses solid state light engines that can dynamically adjust spectral parameters and illumination characteristics, providing stable, high-intensity light across the visible spectrum while maintaining cost-effectiveness through efficient LED-based technology
3Adaptability or versatility
If a fixed collimator is used, then the device complexity is low, but the adaptability to different microscopes and applications is limited
Solution Approach 1:
The collimator incorporates adjustable elements including focal distance adjustment and illumination area control, transforming a static component into a dynamic one that can adapt to different applications and microscope configurations
Solution Approach 2:
The adjustable collimator serves as an intermediary component between the light guide and microscope, providing interface flexibility and optimization capability that accommodates variations in both light sources and microscope optical trains
4Productivity
If poor light coupling is used, then the device complexity is low, but the illumination efficiency and imaging quality are poor
Solution Approach 1:
The collimator is designed to pre-optimize the light beam characteristics before it enters the microscope optical train, performing focal adjustment and beam shaping in advance to maximize coupling efficiency and imaging performance
