Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional telematics solutions are used, then vehicle monitoring functionality is achieved, but system complexity and cost increase significantly
Solution Approach 1:
The patent combines multiple telematics functions (GPS tracking, cellular communication, Wi-Fi connectivity, vehicle diagnostics) into a single integrated gateway device that connects to the vehicle bus. This consolidation eliminates the need for separate displays, antennas, and wiring harnesses, directly reducing system complexity while maintaining full monitoring functionality.
Solution Approach 2:
The gateway device is designed as a universal platform that can communicate with various vehicle bus protocols (CAN, LIN, MOST) and provide multiple communication interfaces (USB, Wi-Fi, Bluetooth, cellular). This multi-functional design allows a single device to replace entire telematics systems, reducing complexity without sacrificing functionality.
2Reliability
If traditional telematics solutions are used, then vehicle monitoring functionality is achieved, but installation cost and wiring requirements increase
Solution Approach 1:
The patent extracts the communication and processing functions from the vehicle's original wiring system and consolidates them into a standalone gateway device. This extraction eliminates the need for extensive custom wiring between multiple components, as the gateway handles all communications through standardized interfaces and onboard processors.
Solution Approach 2:
The gateway acts as an intermediary device that bridges the vehicle bus and external communication networks. It provides standardized connection interfaces (USB, Wi-Fi) that simplify installation compared to direct integration with multiple vehicle systems, reducing both installation complexity and cost.
3Adaptability or versatility
If separate displays and antennas are used, then monitoring capabilities are provided, but device complexity and cost increase
Solution Approach 1:
The gateway device provides universal communication capabilities through multiple interfaces (USB for wired connection, Wi-Fi for wireless, Bluetooth for short-range communication, and cellular for remote transmission). This eliminates the need for separate displays and antennas, as the gateway can communicate with various devices through these standardized protocols, reducing complexity while maintaining versatility.
Solution Approach 2:
The gateway device is designed to be self-sufficient, incorporating its own processing unit, memory, and communication interfaces. It can independently process vehicle data, establish connections, and transmit information without requiring external displays or antennas, thereby reducing overall system complexity while maintaining full monitoring capabilities.
Data Source
AI summary
A system and method of transmitting vehicle information from a vehicle to a server across an external network. A vehicle bus connector module is plugged into a vehicle bus through the vehicle's vehicle bus connector. The vehicle bus connector module is also communicatively connected to a personal communications device. Vehicle information is collected from the vehicle bus and combined with information captured by the personal communications device to form a driver log. The driver log is transmitted to the server via the external network.
