Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If aperture diameters of stops are adjusted based on control information from external controlling device, then light amounts in multiple optical systems can coincide, but device complexity and processing complexity increase
Solution Approach 1:
The patent stores predetermined control information (aperture diameter settings) in a storage unit before actual operation. When light amount adjustment is needed, the controller simply retrieves and executes the stored control information without requiring complex real-time calculations or external controlling devices, thus reducing processing complexity while achieving uniform light distribution across multiple optical systems
Solution Approach 2:
The system uses its own stored control information to automatically adjust aperture diameters without needing external controlling devices. The controller internally manages the adjustment process by referencing pre-stored data, making the system self-sufficient and eliminating the need for complex external control mechanisms
2Illumination intensity
If aperture diameters are adjusted using external controlling device, then brightness uniformity improves, but ease of operation deteriorates
Solution Approach 1:
The system automatically adjusts aperture diameters using its own stored control information without requiring external controlling devices or complex user operations. The controller internally retrieves and executes the appropriate control information, making the system easy to operate while maintaining brightness uniformity across multiple optical systems
3Measurement precision
If complex signal or image processing is used to synchronize aperture diameters, then light amount adjustment precision improves, but device complexity increases
Solution Approach 1:
The patent stores predetermined control information (aperture diameter settings) in a storage unit before actual operation. When light amount adjustment is needed, the controller simply retrieves and executes the stored control information without requiring complex real-time calculations or external controlling devices, thus reducing processing complexity while achieving uniform light distribution across multiple optical systems
Solution Approach 2:
The system uses stored control information (a form of data copy) to guide aperture diameter adjustments instead of performing complex real-time signal or image processing. The controller references the stored control information to determine the appropriate aperture settings, achieving precise light amount adjustment with simpler hardware and processing
