Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle constantly communicates with many entities and objects in the traffic system using V2X technology, then safety and collision prevention are improved, but communication efficiency and system complexity deteriorate
Solution Approach 1:
The patent segments the communication task by dividing sensor data into different types (e.g., safety-critical data vs. non-critical data) and transmitting them through different interfaces. Safety-critical data is transmitted via direct V2X communication (PC5 interface) for immediate response, while non-critical data is transmitted through network infrastructure (Uu interface). This segmentation reduces communication complexity while maintaining safety improvements.
Solution Approach 2:
The patent introduces a network server as an intermediary that receives, processes, and redistributes sensor data. The server acts as a mediator between the vehicle and multiple traffic entities, managing communication routes and data distribution. This intermediary approach simplifies the vehicle's communication burden while ensuring safety-critical information reaches relevant entities efficiently.
2Loss of information
If sensor data is transmitted to all entities in the V2X network, then information availability is improved, but communication efficiency and energy consumption deteriorate
Solution Approach 1:
The patent applies local quality by determining the relevance of sensor data to specific receiving entities based on their location, type, and current state. Different entities receive different subsets of data tailored to their local needs. For example, only vehicles in proximity to a detected obstacle receive obstacle-related data, while infrastructure entities receive aggregated traffic flow information. This selective data distribution maintains information availability for relevant entities while improving communication efficiency.
Solution Approach 2:
The patent implements partial action by transmitting only the necessary portion of sensor data to each entity rather than all data. The system determines the minimum required data set for each receiving entity based on relevance criteria, avoiding excessive data transmission. This approach ensures that entities receive sufficient information for their specific needs without the overhead of processing unnecessary data.
3Adaptability or versatility
If multiple communication interfaces are used for V2X data transmission, then adaptability and coverage are improved, but device complexity and data management difficulty worsen
Solution Approach 1:
The patent implements multi-functionality by designing the communication system to handle multiple interface types (PC5 for direct V2X, Uu for network-based) through a unified data management architecture. The same sensor data can be routed to different interfaces based on relevance and requirements, allowing the system to adapt to various communication scenarios without requiring separate management mechanisms for each interface type.
Solution Approach 2:
The patent applies dynamics by making the interface selection adaptive and changeable based on real-time conditions. The system dynamically determines which interface to use for transmitting data to each entity, considering factors such as entity type, location, data urgency, and network conditions. This dynamic interface selection allows the system to adapt to changing traffic scenarios while simplifying management through automated decision-making algorithms.
