Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image processing is performed through CPU and GPU on the motherboard, then image processing capability is improved, but power consumption increases and service life reduces
Solution Approach 1:
The patent extracts the image processing function from the motherboard's CPU and GPU, and relocates it to the camera module itself. The camera performs image processing locally and only transmits the processed image data to the display, eliminating the need for continuous motherboard involvement in image processing operations.
Solution Approach 2:
The system is segmented into independent functional modules: the camera module handles image acquisition and processing, the display module handles image presentation, and the motherboard provides basic connectivity. This segmentation allows each module to operate independently with minimal motherboard intervention, reducing overall power consumption.
2Measurement precision
If image processing is performed through CPU and GPU on the motherboard, then image processing capability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the image processing function from the motherboard's complex CPU-GPU architecture and relocates it to the camera module. This simplifies the motherboard's role to basic data transmission while maintaining full image processing capability at the camera level.
Solution Approach 2:
The camera module becomes self-sufficient by performing its own image processing operations without requiring the motherboard's processing resources. This self-service approach reduces the interdependence between components and simplifies the overall system architecture.
3Extent of automation
If data communication goes through the motherboard, then centralized control is improved, but communication efficiency reduces
Solution Approach 1:
The patent introduces a direct communication channel between the camera and display modules, using the motherboard only as an optional intermediary for device identification and initial pairing. Once paired, images can be transmitted directly between camera and display, bypassing the motherboard for improved efficiency.
Solution Approach 2:
The system performs preliminary device pairing and identification through the motherboard before establishing direct communication channels. This preliminary action through the centralized controller enables subsequent efficient direct communication without continuous motherboard involvement.
