Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated optical members are used for different models of image forming devices, then the optical performance for each specific model is optimized, but the device complexity increases and the sharing of optical components across various devices becomes impossible
Solution Approach 1:
The optical member is designed with multiple pairs of opposing surfaces (at least three pairs), where each pair includes a lens with specific curvature characteristics. This configuration allows a single optical member to serve multiple functions and be compatible with various models of image forming devices, eliminating the need for dedicated optical members for each model while maintaining optimized optical performance.
2Adaptability or versatility
If multiple types of optical members are provided for different photography distances, then the adaptability for various shooting scenarios is improved, but the quantity of components increases and the simplicity of configuration is lost
Solution Approach 1:
The optical member is segmented into multiple pairs of opposing surfaces, with each pair containing lenses having different curvature characteristics. This segmentation allows different regions or surface pairs to be used for different photography distances (close-up, normal, telephoto), enabling versatility while maintaining a single integrated component structure.
Solution Approach 2:
The optical member provides dynamic adaptability through its multiple surface configurations, allowing the system to switch between different optical modes (close-up, normal, telephoto) by utilizing different pairs of opposing surfaces, thereby achieving versatility without increasing the number of separate components.
