Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional spectral sorters are used for textile recycling, then basic fiber classification can be performed, but the accuracy and efficiency are insufficient due to the complexity of blended fibers and various colors/patterns
Solution Approach 1:
The detection system is segmented into multiple functional modules: height sensor for positioning, excitation light source for Raman signal generation, optical detector for signal reception, and focuser for beam focusing. This segmentation allows each module to be optimized independently, improving detection accuracy while managing system complexity through modular design.
Solution Approach 2:
The height sensor performs preliminary measurement of the test specimen's position before the optical detection occurs. This preliminary action allows the focuser to pre-adjust the excitation light beam focus to the correct depth, ensuring optimal detection accuracy when the optical detector scans the specimen, rather than attempting to focus during the detection process itself.
2Productivity
If optical detection is performed on moving specimens without height adjustment, then continuous processing is maintained, but detection accuracy decreases due to varying specimen heights
Solution Approach 1:
The height sensor measures the specimen height at a first position before the optical detector performs detection at a second position. This preliminary height measurement enables the focuser to adjust the excitation light beam focus in advance, ensuring accurate detection even as specimens move continuously through the system at varying heights.
Solution Approach 2:
The height sensor provides real-time feedback on specimen position and height variations. This feedback is used by the control system to dynamically adjust the focuser's excitation light beam focus, maintaining optimal detection accuracy throughout continuous operation without interrupting the specimen flow.
3Measurement precision
If the excitation light beam is not focused according to specimen height, then the system structure remains simple, but the detection accuracy and sorting efficiency are compromised
Solution Approach 1:
The focus adjustment function is segmented as a separate focuser module with a movable lens, distinct from the excitation light source and optical detector. This segmentation allows the focus adjustment mechanism to be independently controlled by height sensor feedback, improving detection accuracy while keeping the overall system architecture manageable through clear functional separation.
