Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the first solution (mobile phone chip) is used, then voice call function is achieved, but video capture capability is insufficient and power consumption is high
Solution Approach 1:
The system is divided into independent functional modules: a 4G communication module for voice calls and a separate audio/video capture module for professional video capture. These modules communicate through standardized interfaces (UVC, UART), allowing each module to be optimized independently for its specific function while maintaining overall system versatility.
2Adaptability or versatility
If the first solution (mobile phone chip) is used, then voice call system is supported, but power consumption increases after long-time operation
Solution Approach 1:
By separating the 4G communication module from the audio/video capture module, the system can independently manage power consumption. The 4G module can maintain voice call functionality at low power states while the capture module remains dormant or operates only when needed, significantly reducing overall power consumption during extended operation.
Solution Approach 2:
Each module is designed to be self-contained with its own processing capabilities. The audio/video capture module handles its own encoding and processing through the UVC interface without requiring continuous high-power operation of the main processor, enabling energy-efficient long-term operation.
3Reliability
If the second solution (multimedia chip with 4G module) is used, then video capture capability is improved, but system complexity and chip requirements increase
Solution Approach 1:
The audio/video capture module is designed with universal interfaces (UVC, UART) that can communicate with different 4G communication modules through standardized protocols. This modular approach reduces system complexity by allowing the same capture module to work with various 4G modules, eliminating the need for highly complex integrated multimedia chips with proprietary interfaces.
4Adaptability or versatility
If Linux-based 4G module is used, then communication function is achieved, but response speed and startup time are limited
Solution Approach 1:
The audio/video capture module is designed to be pre-configured and ready to operate independently. It can initialize and start capturing audio/video data immediately through the UVC interface without waiting for the 4G module's Linux system to fully boot up, achieving startup times within 4 seconds by performing necessary actions in advance and in parallel.
