Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of optical elements for tilt and shift imaging is implemented, then imaging flexibility is improved, but operational complexity and time consumption increase
Solution Approach 1:
The system provides self-service functionality by automatically returning optical elements to preset positions when tilt or shift imaging modes are deactivated. This eliminates the need for manual reset operations, reducing operational complexity while maintaining imaging flexibility. The control unit automatically manages the return-to-position process based on mode switching signals.
Solution Approach 2:
Preset positions for optical elements are pre-calculated and stored in the control unit for different tilt and shift imaging modes. This preliminary preparation allows rapid switching between imaging modes without requiring manual adjustment, thereby improving ease of operation while preserving adaptability.
2Measurement precision
If precise manual adjustment of optical elements is performed, then imaging precision is improved, but time consumption increases
Solution Approach 1:
The control unit stores preset positions corresponding to various tilt and shift imaging modes in advance. When a mode is activated, the system automatically moves optical elements to the pre-calculated positions, eliminating the need for manual precise adjustment and significantly reducing time consumption while maintaining imaging precision.
Solution Approach 2:
The patent replaces manual mechanical adjustment with automated motor-driven positioning controlled by a control unit. This substitution enables rapid, precise positioning of optical elements to preset locations, reducing both time consumption and operational complexity while maintaining imaging precision.
3Productivity
If automated control of optical elements is implemented, then operational efficiency is improved, but device complexity increases
Solution Approach 1:
The control unit automatically manages the positioning of optical elements by detecting mode switching signals and autonomously controlling motors to return elements to preset positions. This self-service capability improves operational efficiency without requiring complex external control systems, as the automation is integrated within the existing lens apparatus.
