Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image data from multiple sensor devices is transmitted to the head end for analysis, then comprehensive monitoring and analysis can be achieved, but large data transmission bandwidth is required
Solution Approach 1:
The patent divides the image processing function into two segments: the image processor circuit performs preliminary analysis of detection signals from sensor devices and extracts key information, while the central processor circuit receives only the analyzed results rather than raw image data. This segmentation allows comprehensive monitoring while significantly reducing the bandwidth required for data transmission.
2Ease of operation
If all images are analyzed at the head end, then centralized control is achieved, but resource-intensive high bandwidth is required
Solution Approach 1:
The image processor circuit acts as an intermediary between the sensor devices and the central processor circuit. It processes detection signals locally and transmits only the essential analyzed information to the central processor, thereby maintaining centralized control capability while dramatically reducing resource consumption and bandwidth requirements.
3Adaptability or versatility
If sensor device module and display module are independently designed, then module flexibility is achieved, but large bandwidth is needed for image transmission
Solution Approach 1:
The patent merges the image processing function into the system chip by integrating the image processor circuit and central processor circuit on the same chip. This integration allows the sensor device module and display module to remain independently designed and flexible, while the combined processing capability reduces the bandwidth needed for image data transmission by processing images locally rather than transmitting them externally.
