Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the microscope is fixed in position, then the device structure is simplified, but the ability to perform focus adjustment and obtain clear luminance information is lost
Solution Approach 1:
Instead of moving the microscope to achieve focus (conventional approach), this patent inverts the approach by moving the V-shaped groove holding the optical fiber while keeping the microscope fixed. The V-shaped groove driving unit translates the groove along the optical axis to achieve focus adjustment, thereby simplifying the overall device structure while maintaining measurement precision.
Solution Approach 2:
The V-shaped groove acts as an intermediary between the fixed microscope and the optical fiber. By moving the V-shaped groove rather than the microscope or fiber directly, the system achieves focus adjustment through a simplified mechanical interface, resolving the contradiction between structural simplicity and measurement capability.
2Ease of operation
If the V-shaped groove is movable, then focus adjustment is enabled with a fixed microscope, but the positioning precision and alignment accuracy may be compromised
Solution Approach 1:
The system employs feedback mechanisms where the microscope continuously monitors the luminance information of the optical fiber as the V-shaped groove moves. This real-time feedback enables precise control of the groove's position, ensuring that focus adjustment is achieved without compromising alignment accuracy. The feedback loop allows the system to automatically compensate for positioning variations.
3Stability of the object's composition
If the microscope position is fixed, then the device is more stable, but the flexibility to adjust focus for different optical fibers is reduced
Solution Approach 1:
The system introduces dynamic capability through the movable V-shaped groove while keeping the microscope static. The groove can be dynamically positioned along the optical axis to accommodate different optical fiber lengths and focal requirements, providing adaptability without compromising microscope stability. This dynamic adjustment mechanism enables the fixed microscope to serve multiple focus requirements.
