Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment and positioning methods are used, then professional skill and knowledge are required, but this increases labor intensity and reduces measurement reliability
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated positioning system that uses a guide means and servomotor to precisely position the optic along its central axis. This substitution eliminates the need for professional skill and manual adjustment, thereby reducing labor intensity while maintaining or improving measurement reliability.
Solution Approach 2:
The positioning system is designed to automatically position the optic without human intervention. The guide means and servomotor work together to self-adjust the optic's position, eliminating the need for operators to manually adjust and position components, thus reducing labor intensity and potential human error.
2Reliability
If manual positioning is used, then adjustment flexibility is available, but this increases the risk of inaccuracies and errors
Solution Approach 1:
The patent replaces complex manual positioning operations with an automated system comprising guide means and a servomotor. This automation reduces the risk of human error and improves test result reliability, while the system's modular design keeps the added complexity manageable.
Solution Approach 2:
The positioning system is segmented into distinct functional components: the guide means for defining the movement path and the servomotor for actuation. This segmentation allows each component to be optimized independently and simplifies the overall system control, reducing complexity while improving reliability.
3Adaptability or versatility
If multiple degrees of freedom are allowed for optic adjustment, then positioning flexibility is improved, but this increases the complexity of blocking degrees of freedom
Solution Approach 1:
The patent extracts and eliminates unnecessary degrees of freedom by designing the guide means to constrain the optic's movement to only the necessary longitudinal adjustment along its central axis. This removes the complexity of managing multiple degrees of freedom while retaining the essential positioning flexibility needed for testing.
