Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If spectral sorters are used to detect and sort textile materials, then sorting capability is provided, but detection accuracy is insufficient due to the complexity of fiber materials and blended fibers
Solution Approach 1:
The detection process is segmented into multiple stages: height measurement at the first position, focus adjustment based on height data, and spectral detection at the second position. This segmentation allows each stage to be optimized independently, improving overall detection accuracy for complex fiber materials
Solution Approach 2:
The height measurement and focus adjustment are performed as preliminary actions before the actual spectral detection. By pre-adjusting the focus based on height data obtained at the first position, the system ensures optimal detection conditions are established before analyzing the complex fiber materials at the second position
2Productivity
If optical detection is performed on moving specimens, then continuous sorting is achieved, but detection accuracy decreases due to varying heights of specimens
Solution Approach 1:
The system dynamically adjusts the focus of the optical detection device based on real-time height measurements of moving specimens. The focus adjustment is continuously adapted to match the varying heights of specimens on the conveyor belt, maintaining detection accuracy while enabling continuous operation
Solution Approach 2:
The system uses feedback from height measurements taken at the first position to automatically adjust the focus at the second position. This closed-loop feedback mechanism ensures that the optical detection remains accurately focused on specimens of varying heights, maintaining precision during continuous sorting operations
3Measurement precision
If focus adjustment is made for each specimen, then detection accuracy is improved, but processing time increases
Solution Approach 1:
The height measurement and focus adjustment are performed as preliminary actions before the specimen reaches the detection position. This advance preparation eliminates time delays during the actual detection process, as the focus is already optimized when the specimen arrives at the second position
Solution Approach 2:
The height measurement and focus adjustment operations continue uninterrupted as specimens move along the conveyor belt. The system maintains continuous operation by performing focus adjustments in parallel with specimen transport, avoiding stoppages and maintaining high processing speed while ensuring detection accuracy
