Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional vehicle-mounted terminals are used, then basic communication functions are provided, but security and reliability are insufficient
Solution Approach 1:
The vehicle-mounted terminal is divided into multiple independent functional modules: main control unit, communication module, power management module, and security chip module. Each module performs a specific function and can be independently selected and configured, allowing the system to achieve high reliability through specialized security hardware while maintaining adaptability through modular reconfiguration for different application scenarios.
Solution Approach 2:
The main control unit is designed with multi-functional capabilities, integrating vehicle data processing, terminal control, and communication coordination functions. This universal design allows a single platform to support diverse smart transportation applications including collision warning, blind spot detection, lane change assistance, and collaborative driving, thereby achieving both reliability and versatility.
2Adaptability or versatility
If fixed scene and single function terminals are deployed, then device complexity is reduced, but adaptability and scalability are poor
Solution Approach 1:
The terminal system is segmented into standardized interface modules with defined communication protocols. The main control unit interacts with the security chip module, communication module, and power management module through standardized interfaces, enabling flexible reconfiguration and scaling without increasing overall system complexity. This modular architecture allows selective deployment of functions based on specific application needs.
Solution Approach 2:
The terminal system employs dynamic configuration capabilities where the main control unit can adaptively adjust communication parameters, power management settings, and security protocols based on real-time operational requirements. This dynamic behavior enables the system to scale from basic to advanced functions without requiring complete system redesign, thereby improving adaptability while managing complexity.
3Reliability
If comprehensive security measures are implemented, then security and reliability improve, but device complexity and cost increase
Solution Approach 1:
Security functions are extracted from the main control unit and implemented in a dedicated security chip module. This separation allows comprehensive security measures including encryption, decryption, and security certification to be implemented in a specialized hardware component, thereby improving communication security while preventing the main control unit from becoming overly complex. The security chip module can be independently selected and upgraded without affecting other system components.
