Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual focusing operation is used, then the user can control the focus, but the operation steps are tedious and time-consuming
Solution Approach 1:
The system automatically detects moving objects and performs focusing operations without user intervention. The terminal device self-services by monitoring object movement through image processing and autonomously adjusting focus parameters, eliminating the need for manual focusing operations while reducing time loss.
Solution Approach 2:
The system continuously monitors the movement status of objects in the captured images and uses this feedback to dynamically adjust focusing parameters. By detecting object movement and feeding this information back to the focusing mechanism, the system automatically adapts focus settings, resolving the contradiction between manual operation complexity and time efficiency.
2Ease of operation
If automatic refocusing is used, then the operation is simplified, but the refocusing time is lengthy
Solution Approach 1:
The system performs preliminary detection of object movement characteristics before focusing is needed. By continuously monitoring and pre-processing image data to identify moving objects and their movement states, the system prepares focus adjustment parameters in advance, enabling faster refocusing when needed and reducing overall refocusing time.
Solution Approach 2:
The focusing system dynamically adapts to object movement by continuously adjusting focus parameters based on real-time movement detection. Rather than using fixed refocusing intervals, the system dynamically responds to actual object motion, optimizing refocusing timing and reducing unnecessary waiting time while maintaining ease of operation.
3Productivity
If focusing on moving objects is attempted, then the image can be captured, but the image quality becomes blurry
Solution Approach 1:
The system performs preliminary detection of object movement characteristics before capturing images. By identifying moving objects and calculating their movement parameters in advance, the system can pre-adjust focusing parameters to compensate for motion, enabling clear image capture of moving objects without blur.
Solution Approach 2:
The system dynamically changes focusing parameters based on detected object movement characteristics. By adjusting focus distance, focal length, or other focusing parameters according to the movement speed and direction of objects, the system maintains image clarity while capturing moving subjects, resolving the contradiction between capture capability and image precision.
