Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-sensor camera device captures stereo image pairs simultaneously, then 3D viewing effect is achieved, but image outputs from different sensors are not synchronized
Solution Approach 1:
The system uses the existing image data from the sensors themselves to detect asynchronization, rather than requiring external synchronization signals or additional hardware. The detection circuit analyzes the captured image outputs to determine timing differences, allowing the system to self-diagnose and self-correct synchronization issues.
Solution Approach 2:
The system implements a feedback loop where the detection circuit continuously monitors image outputs for asynchronization, and the control circuit adjusts sensor operation based on detected timing differences. This closed-loop control ensures continuous synchronization without requiring complex external synchronization mechanisms.
2Reliability
If traditional synchronization mechanisms or buffers are used to synchronize image outputs, then asynchronization is reduced, but device complexity and resource consumption increase
Solution Approach 1:
The patent extracts the synchronization control function from complex external synchronization mechanisms and buffers, implementing it instead through simple detection and control circuits that operate directly on the existing image data flow. This removes the need for additional synchronization hardware while maintaining synchronization reliability.
Solution Approach 2:
Rather than requiring external synchronization signals or dedicated synchronization buffers, the system uses the image data itself as the basis for detecting and correcting timing differences. The sensors and processing circuits serve their primary functions while simultaneously enabling synchronization control through intelligent analysis of the captured data.
3Productivity
If image outputs from multiple sensors are processed independently, then processing speed is maintained, but asynchronization between left-view and right-view images occurs
Solution Approach 1:
The detection circuit provides continuous feedback on the timing relationship between image outputs from different sensors. The control circuit uses this feedback to dynamically adjust sensor operation timing, ensuring synchronized output while maintaining high processing speeds through efficient, real-time control rather than slow external synchronization mechanisms.
