Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional vehicle-to-vehicle communication systems are used, then information sharing is limited to basic GPS location data, but the system suffers from temporary connectivity loss and cannot maintain reliable communication in off-road scenarios
Solution Approach 1:
The patent implements a dynamic wireless mesh network where routing rules are continuously adjusted based on real-time communication parameters such as signal strength, vehicle distance, and velocity. This dynamic adaptation allows the system to maintain reliable communication connections even as vehicles move and environmental conditions change, resolving the contradiction between communication reliability and adaptability to varying scenarios
Solution Approach 2:
The system monitors and responds to changes in communication parameters (signal strength, distance, velocity) by selectively adjusting routing rules. When parameters indicate deteriorating communication conditions, the system adapts by selecting alternative routes or adjusting transmission parameters, thereby maintaining reliable communication while adapting to different operational environments
2Reliability
If a dynamic wireless mesh network is established with real-time parameter monitoring and routing rule adjustment, then communication reliability improves, but the system complexity increases
Solution Approach 1:
The wireless mesh network operates with distributed intelligence where each vehicle node autonomously monitors communication parameters and participates in routing decisions. The system self-adjusts routing rules based on collective parameter data from all nodes, reducing the need for centralized control and minimizing the complexity burden on individual vehicles while maintaining high network reliability
Solution Approach 2:
The communication system integrates multiple functions including parameter monitoring, dynamic routing, information sharing, and driver feedback into a unified wireless mesh network platform. This multi-functional approach consolidates complexity into a single system that handles all communication needs, rather than requiring separate systems for each function
3Productivity
If routing rules are selectively adjusted in real-time based on communication parameters, then information sharing efficiency improves, but the computational load and processing time increase
Solution Approach 1:
The system pre-establishes wireless mesh network connections and pre-calculates potential routing paths before communication needs arise. By maintaining ready-to-use routing rules and pre-monitoring communication parameters, the system can quickly adapt to changing conditions without extensive real-time computation, thus improving information sharing efficiency while minimizing processing delays
