Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a scanning gun is used to scan the carved code, then the code reading function is achieved, but online quality detection capability is lost
Solution Approach 1:
The patent replaces the mechanical scanning gun system with an optical imaging system consisting of a camera, light source, and image processing unit. This substitution enables automated online quality detection by capturing images of the carved code and using algorithmic analysis to assess code quality, thereby achieving both automation and reliable detection accuracy simultaneously.
Solution Approach 2:
The patent creates an optical copy (image) of the carved code using a camera system, then analyzes this copy through image processing algorithms. This copying approach allows comprehensive quality assessment including depth, clarity, and completeness without requiring physical contact or manual inspection, enabling reliable automated online detection.
2Reliability
If manual visual inspection is used for carved code detection, then detection capability is achieved, but labor cost increases and false/missed detections occur
Solution Approach 1:
The patent implements a self-service detection system where the imaging system automatically captures, processes, and analyzes the carved code without human intervention. The system includes self-calibration capabilities and automatic quality assessment algorithms that eliminate the need for manual visual inspection while maintaining high detection accuracy and reducing false/missed detections.
Solution Approach 2:
The patent incorporates feedback mechanisms where the image processing system continuously monitors carved code quality and provides real-time detection results. The system uses feedback from image analysis to adjust detection parameters and maintain optimal detection accuracy, automatically compensating for variations in lighting, code position, and quality standards without requiring complex manual adjustments.
3Manufacturing precision
If the imaging assembly is fixed at a constant distance from the object, then the structure is simple, but image clarity varies with object position
Solution Approach 1:
The patent implements a dynamic distance adjustment mechanism that allows the imaging assembly to automatically adjust its distance from the object being detected. This dynamic adjustment ensures that the imaging system maintains optimal focus and clarity regardless of variations in object position on the conveyor belt, thereby improving image capture accuracy without requiring overly complex mechanical structures.
Solution Approach 2:
The patent changes the distance parameter between the imaging assembly and the object dynamically based on detected object position. By adjusting this critical parameter in real-time, the system maintains optimal imaging conditions for accurate carved code detection, balancing the need for precision with acceptable mechanical complexity.
