Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual blanking and sorting methods are used, then操作简单 (operation is simple), but 劳动成本高 (labor cost is high) and 效率低 (efficiency is low)
Solution Approach 1:
The system uses vision recognition to automatically identify leather slice types and positions, and the manipulator automatically picks and sorts them without human intervention. The apparatus serves itself by using the camera to guide the manipulator's actions, eliminating the need for manual operation while achieving high automation.
Solution Approach 2:
The patent replaces manual mechanical sorting with an automated system combining vision recognition (camera) and robotic manipulation (manipulator). The camera captures images of leather slices, processes them to identify types and positions, and controls the manipulator to automatically pick and sort the slices, substituting human mechanical actions with automated mechanical-electrical-optical integration.
2Productivity
If multiple workers are used for blanking and sorting, then 操作灵活性 (operational flexibility) is maintained, but 生产效率低 (production efficiency is low)
Solution Approach 1:
The system achieves self-service automation where the camera automatically captures and processes images of leather slices, identifies their types and positions, and controls the manipulator to pick and sort them. This automated loop eliminates manual labor while maintaining continuous operation, significantly improving productivity compared to manual methods.
Solution Approach 2:
The vision recognition system provides real-time feedback by capturing images of leather slices, processing them to determine slice types and positions, and using this information to guide the manipulator's picking and sorting actions. This closed-loop feedback mechanism ensures accurate and efficient automated operation, enhancing productivity while reducing manual intervention.
3Measurement precision
If manual sorting is performed, then 分类准确性 (classification accuracy) depends on worker skill, but 时间消耗大 (time consumption is high)
Solution Approach 1:
The patent replaces manual visual inspection and sorting with an automated vision recognition system. The camera captures images of leather slices, and image processing algorithms automatically identify slice types and positions with high accuracy, eliminating dependence on worker skill and significantly reducing classification time compared to manual methods.
Solution Approach 2:
The system creates a digital copy of the leather slice arrangement by capturing images with the camera. This optical copy is then processed through image recognition algorithms to identify slice types and positions, enabling rapid and accurate classification without physically handling each piece, thus reducing time loss while maintaining high accuracy.
