Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data compression rate is increased to improve transmission efficiency, then communication speed improves, but image data quality deteriorates
Solution Approach 1:
The system dynamically adjusts the compression rate based on real-time travel speed and communication capacity conditions. When the autonomous vehicle travels at higher speeds or experiences limited communication capacity, the compression rate is increased to maintain transmission efficiency. When conditions improve, the compression rate is reduced to enhance image data quality, thus adaptively resolving the contradiction between transmission efficiency and data quality.
2Device complexity
If single telecommunication device is used to simplify system structure, then device complexity reduces, but communication reliability deteriorates in diverse environments
Solution Approach 1:
The telecommunication system is segmented into multiple independent telecommunication devices, each capable of establishing separate communication connections. This segmentation allows the system to diversify communication channels and improve reliability in diverse environments while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The system changes the parameter of communication capacity by utilizing multiple telecommunication devices with different communication capabilities. By selecting and switching between devices based on environmental conditions, the system optimizes communication reliability without requiring all devices to operate simultaneously, thus controlling overall system complexity.
3Speed
If compression rate is increased for higher travel speed to maintain transmission efficiency, then communication capacity utilization improves, but data transmission accuracy deteriorates
Solution Approach 1:
The system implements feedback mechanisms that continuously monitor travel speed, communication capacity, and data transmission quality. Based on this feedback, the compression rate is dynamically adjusted to maintain an optimal balance. When travel speed increases, the system responds by adjusting compression parameters to prevent excessive information loss, ensuring data transmission accuracy is maintained despite higher speeds.
