Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera is used to detect the entry depth and position of a target object in a spatial projected image, then the detection precision is improved, but the device complexity increases
Solution Approach 1:
The camera is configured to detect both the entry depth and entry position of the target object simultaneously from a single captured image, making the detection device multi-functional. This allows one component to perform multiple detection tasks that would otherwise require separate sensors, thereby improving measurement precision without proportionally increasing device complexity
Solution Approach 2:
The processing unit acts as an intermediary that receives the captured image from the camera and extracts both depth and position information through image processing algorithms. This intermediary processing layer enables the camera to indirectly measure multiple parameters (depth and position) from a single image, achieving high measurement precision while keeping the physical device structure relatively simple
2Adaptability or versatility
If the spatial image forming plane is included within the angle of view of the camera, then the detection coverage is improved, but the image quality may deteriorate
Solution Approach 1:
The system focuses the camera's detection capability on the specific region of interest (the spatial image forming plane) while maintaining awareness of the broader environment. By strategically positioning the camera and using image processing to emphasize the relevant area, the system achieves both comprehensive detection coverage and maintained image quality in the critical detection zone
