Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 3G/4G network and GPS are used for vehicle monitoring and warning, then positioning accuracy and network coverage are improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the essential function of vehicle-to-vehicle communication from the complex 3G/4G+GPS system, using only short-range wireless communication (Wi-Fi Direct or Bluetooth) combined with OBD real-time data to achieve anomaly detection and warning, eliminating the need for cloud servers and complex network infrastructure
Solution Approach 2:
The system uses the vehicle's own OBD system to generate real-time data and the short-range wireless communication capabilities already present in modern vehicles to perform monitoring and warning functions, making the system self-sufficient without external infrastructure support
2Measurement precision
If 3G/4G network positioning is used to determine vehicle status, then monitoring accuracy is improved, but response time and cost worsen
Solution Approach 1:
The system continuously collects and analyzes vehicle data through OBD in real-time before anomalies occur, maintaining a ready state for immediate detection and warning, eliminating the time delay associated with periodic cloud-based monitoring
Solution Approach 2:
The patent replaces the cloud-based network communication system with direct short-range wireless communication between vehicles, substituting a complex centralized system with a simpler decentralized approach that enables faster local response
3Adaptability or versatility
If additional mounting apparatus is installed for intelligent driving assistance, then monitoring capability is improved, but device complexity and cost increase
Solution Approach 1:
The system uses the vehicle's existing OBD system and short-range wireless communication capabilities to perform multiple functions including real-time monitoring, anomaly detection, and inter-vehicle warning, eliminating the need for dedicated additional mounting apparatus
Solution Approach 2:
The invention leverages the vehicle's own existing systems (OBD for data collection and built-in wireless communication for transmission) to provide intelligent driving assistance functions, making the vehicle serve itself without requiring external additional apparatus
