Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple optical filters are arranged on a rotating tray to enable multi-wavelength detection, then the detection capability is improved, but the number of mechanical parts and device complexity increases
Solution Approach 1:
Multiple optical filters are merged onto a single rotating tray, allowing them to be switched together as one unit. This combining of multiple filters into one rotating assembly reduces the need for separate mounting mechanisms for each filter, thereby reducing overall mechanical complexity while maintaining multi-wavelength detection capability.
Solution Approach 2:
The rotating tray serves multiple functions: it holds multiple optical filters, provides rotation for switching between them, and positions them along the optical axis. This multi-functional design eliminates the need for separate mechanisms for filter mounting and switching, reducing the total number of mechanical parts.
2Measurement precision
If multiple detection sensors are used to monitor the position of optical filters, then the positioning accuracy is improved, but the device complexity and number of parts increases
Solution Approach 1:
The first and second detection sensors work together as a combined positioning system. The sensors detect the positions of multiple optical filters simultaneously by monitoring the rotating tray's position, eliminating the need for individual sensors for each filter while maintaining accurate position detection.
Solution Approach 2:
The rotating tray acts as an intermediary that links the detection sensors to the optical filters. Instead of directly monitoring each filter's position, the sensors monitor the tray's rotational position, which indirectly but accurately indicates the position of all filters on the tray.
3Speed
If optical filters are arranged along a circumference on a rotating tray, then the switching speed is improved, but the precision of placing filters on the optical axis becomes more difficult
Solution Approach 1:
The optical filters are pre-positioned at specific angular intervals (e.g., 90 degrees) along the circumference of the rotating tray during manufacturing. This preliminary positioning ensures that when the tray rotates to specific angles, the filters automatically align with the optical axis with high precision, eliminating the need for complex real-time adjustment mechanisms.
Solution Approach 2:
The optical filters are arranged asymmetrically at specific angular positions rather than uniformly distributed. This asymmetric arrangement allows each filter to be positioned at an optimal angle for its specific wavelength detection requirements, improving both switching speed and positioning accuracy simultaneously.
