Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual detection method is used to inspect ceramic ball surface defects, then the system complexity is low, but the detection accuracy and productivity are insufficient
Solution Approach 1:
The patent replaces the manual mechanical inspection system with an automated optical inspection system. A camera captures images of ceramic balls on the conveyor belt, and computer software automatically analyzes these images to detect surface defects such as pits and pores, eliminating the need for manual microscopic examination.
Solution Approach 2:
The patent creates optical copies (images) of the ceramic ball surfaces using a camera system. These digital images are then processed by computer algorithms to identify defects, allowing multiple copies of the inspection process to run simultaneously without additional manual labor.
2Productivity
If manual sorting method is used for ceramic balls, then the device complexity is low, but the productivity and sorting efficiency are low
Solution Approach 1:
The system enables self-service automation where the computer-controlled robotic arm independently performs the sorting function. After the software identifies defective balls, the robotic arm automatically picks them up and places them in separate containers without human intervention, allowing the system to serve itself in the sorting task.
Solution Approach 2:
The patent introduces a robotic arm as an intermediary between the detection system and the sorting operation. The robotic arm receives control signals from the computer based on defect detection results and executes the physical sorting action, mediating between the digital detection process and the physical handling of ceramic balls.
3Productivity
If automated image acquisition and analysis system is implemented, then the detection accuracy and productivity are improved, but the device complexity increases
Solution Approach 1:
The patent designs a multi-functional integrated system where a single computer controls multiple functions: image acquisition through the camera, image processing and defect analysis, and robotic arm control for sorting. This universal control approach consolidates multiple separate systems into one coordinated platform, improving productivity while managing complexity through integration.
