Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual picking is used to sort tea leaves by grade, then sorting quality is improved, but picking efficiency decreases and labor is wasted
Solution Approach 1:
The patent combines the picking and sorting functions into a single integrated machine system. The picking module collects tea leaves while the visual detection module and sorting module simultaneously sort them by grade, eliminating the need for separate manual sorting operations and achieving both high efficiency and quality.
Solution Approach 2:
The patent replaces manual visual inspection and sorting with an automated visual detection system using cameras and image processing algorithms. The system automatically identifies tea leaf grades through computer vision technology, substituting human labor with mechanical-optical systems to achieve both speed and accuracy.
2Productivity
If traditional tea picking machine is used, then picking efficiency is improved, but sorting function is lost and tea leaf quality varies
Solution Approach 1:
The patent integrates multiple functions including picking, conveying, visual detection, and sorting into a single unified system. The sorting module works in conjunction with the picking module to ensure that tea leaves are sorted by grade during the picking process itself, maintaining quality uniformity while preserving high picking efficiency.
Solution Approach 2:
The visual detection module provides real-time feedback on tea leaf quality and grade to the control system, which then directs the sorting module to appropriately categorize each batch of picked leaves. This closed-loop control ensures consistent quality output while maintaining efficient operation.
3Manufacturing precision
If manual sorting is performed after machine picking, then sorting is achieved, but labor is wasted and efficiency decreases
Solution Approach 1:
The system performs sorting automatically through the integrated visual detection and sorting modules, making the machine self-sufficient for the sorting task. The system detects, classifies, and sorts tea leaves without requiring manual intervention, thereby eliminating labor requirements while maintaining sorting capability.
Solution Approach 2:
The patent replaces manual sorting operations with an automated mechanical-optical system comprising cameras, processors, and sorting mechanisms. This substitution eliminates the need for human labor in sorting while achieving the same or better sorting precision through automated image analysis and classification.
