Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual detection method is used, then device complexity is low, but measurement precision and productivity are very low
Solution Approach 1:
The patent replaces manual mechanical detection with an automated vision detection system. A camera captures images of the annular component, and image processing algorithms automatically calculate concentricity parameters, eliminating the need for manual measurement tools and operations while significantly improving precision.
Solution Approach 2:
The patent introduces a transparent plate as an intermediary carrier between the annular component and the detection system. This plate provides a stable reference surface and enables standardized positioning, facilitating accurate image capture and measurement while keeping the overall system structure simple.
2Productivity
If manual detection method is used, then device complexity is low, but productivity is very low
Solution Approach 1:
The patent replaces manual detection operations with automated image acquisition and processing. The camera system captures multiple images at different rotation positions, and computer algorithms automatically compute concentricity data, dramatically increasing detection speed and productivity while maintaining simple system architecture.
Solution Approach 2:
The detection system performs self-measurement through automated image capture and processing. The annular component is rotated to predefined positions, the camera automatically captures images, and the system computes results without requiring operator intervention, thereby improving productivity with minimal additional complexity.
3Measurement precision
If backlighting is added for vision detection, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies backlighting selectively to the measurement area where the annular component is positioned on the transparent plate. This localized illumination improves image contrast and measurement precision without requiring complex optical systems throughout the entire device, thereby minimizing the increase in device complexity.

Data Source
AI summary
A concentricity detection system is adapted to detect a concentricity of an annular component. The concentricity detection system includes a support base having a recess on a top surface, a transparent plate received and positioned in the recess, a vision detection device located above the support base and facing the transparent plate, and a backlight source located below the support base and facing the transparent plate. The annular component is disposed in the recess of the support base and supported on a top surface of the transparent plate. The vision detection device is configured to detect the concentricity of the annular component supported on the transparent plate. A through hole is formed in a bottom portion of the recess and a light from the backlight source passes through the support base via the through hole and the transparent plate to provide backlighting for the annular component.
