Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If users actively report dynamic map data, then the quantity of data acquisition increases, but the accuracy of the data deteriorates
Solution Approach 1:
The road operation device automatically performs data acquisition and reporting functions without requiring user intervention. The device self-monitors its operational status and automatically transmits data to the map service system, eliminating the need for users to manually report while ensuring accurate data collection.
2Measurement precision
If government management department provides dynamic map data offline, then the accuracy of data improves, but the timeliness of data acquisition deteriorates
Solution Approach 1:
The road operation device continuously monitors and transmits operational status data in real-time through network connectivity. Instead of periodic offline updates, the device maintains continuous data flow to the map service system, ensuring both accuracy and timeliness by continuously reflecting current road conditions.
Solution Approach 2:
The system implements a feedback mechanism where the road operation device automatically transmits operational status data to the map service system, which then processes and utilizes this information. This closed-loop feedback ensures timely updates while maintaining data accuracy through automated verification processes.
3Reliability
If government management department provides dynamic map data offline, then the reliability of data improves, but the stability of data acquisition deteriorates
Solution Approach 1:
The road operation device autonomously manages data collection and transmission without relying on manual government updates. It self-monitors operational status and automatically reports to the map service system, ensuring stable and reliable data acquisition that is not subject to human factors or administrative delays.
