Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sensor device module and display module are independently designed with all image analysis performed at the head end, then the system can maintain modular design flexibility, but the data transmission bandwidth requirement increases significantly
Solution Approach 1:
The patent merges the image processor circuit into the system chip that also contains the display driver circuit, creating an integrated processing unit. This integration allows image analysis to be performed locally at the display module rather than transmitting all raw image data to the head end, thereby reducing bandwidth requirements while maintaining modular design benefits through the standardized interface between the display module and head end
2Extent of automation
If all image data is transmitted to the head end for analysis, then centralized processing control is maintained, but the transmission bandwidth and processing load increase
Solution Approach 1:
The patent segments the processing functions by dividing the system into two parts: the system chip handles real-time image acquisition and preliminary processing locally, while the head end receives only the processed results or essential data. This segmentation reduces the amount of data that needs to be transmitted while maintaining centralized control over the overall system operation through the coordinated work of both components
3Ease of operation
If image processing is performed at the head end, then system control is simplified, but the real-time processing capability and bandwidth efficiency deteriorate
Solution Approach 1:
The patent implements preliminary action by performing image processing operations locally at the display module through the integrated system chip before data needs to be transmitted to the head end. This preliminary processing at the source reduces the data volume for transmission and enables real-time processing capabilities, while the head end retains simplified control functions for overall system management
