Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the number of mobile devices connected to wireless networks increases, then network coverage expands, but network performance deteriorates
Solution Approach 1:
The routing system dynamically adjusts vehicle routes based on real-time network performance conditions. As network performance deteriorates in certain areas, the system automatically modifies routes to maintain acceptable performance levels, making the routing adaptable to changing network conditions rather than following static optimal paths
Solution Approach 2:
The system changes routing parameters by incorporating network performance metrics (bandwidth, speed, reliability) as additional constraints and optimization criteria. This transforms the traditional routing problem into a multi-parameter optimization problem where network performance becomes a key variable in route determination
2Quantity of substance
If more mobile devices connect to a single wireless access point, then network capacity increases, but bandwidth per device decreases
Solution Approach 1:
The routing system continuously monitors network bandwidth availability and dynamically adjusts routes in response to changing load conditions. When bandwidth per device decreases due to high connectivity density, the system automatically reroutes vehicles to areas with lower network utilization, maintaining adequate bandwidth for driving assistance operations
3Speed
If advanced network technology is deployed, then connection speed increases, but connection range decreases
Solution Approach 1:
The system dynamically balances route selection between high-speed areas with limited range and lower-speed areas with broader coverage. By monitoring real-time network performance, the routing algorithm adapts to the spatial distribution of advanced network infrastructure, optimizing routes to maintain both speed and coverage requirements
4Reliability
If vehicle routes are frequently updated to maintain network performance, then driving assistance reliability improves, but system complexity increases
Solution Approach 1:
The routing system implements a feedback mechanism that monitors network performance metrics and automatically triggers route updates only when performance thresholds are violated. This feedback-driven approach maintains driving assistance reliability by updating routes selectively based on actual network conditions rather than continuously, reducing unnecessary system complexity
Data Source
AI summary
Systems and methods for vehicle routing may be based on wireless network performance data. A vehicle route includes one or more path segments included in the route based on the wireless performance data. The vehicle route may be updated based on updated wireless performance data. Driving assistance features of a vehicle may be enabled by the wireless performance data, and different driving assistance features may be enabled or disabled on the vehicle route according to changes in wireless performance data. As the vehicle traverses the route, the driving assistance features may be enabled or disabled based on the wireless performance data for the path segment. The vehicle route may be updated to continue to enable a set of the driving assistance features.
