Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-definition stream data is transmitted in V2X scenarios, then data transmission quality is improved, but resource wastage increases and collision risks increase
Solution Approach 1:
The patent implements a feedback mechanism where the receiving UE sends acknowledgment signals to the transmitting UE about the reception status of high-definition stream data. Based on this feedback, the transmitting UE adjusts its transmission behavior, stopping data transmission when the receiving UE indicates it has received sufficient data or when channel conditions deteriorate, thereby avoiding resource wastage while maintaining data transmission quality.
Solution Approach 2:
The patent dynamically adjusts transmission parameters including data transmission rate, transmission timing, and content selection based on real-time channel conditions and subscription status. The system transitions from static transmission to dynamic adaptation, modifying transmission characteristics according to current network state to optimize the balance between data quality and resource efficiency.
2Manufacturing precision
If high-definition stream data is transmitted in V2X scenarios, then data transmission quality is improved, but collision risks increase
Solution Approach 1:
The patent implements preliminary actions by having the receiving UE send subscription indications and acknowledgment signals before and during data transmission. The transmitting UE uses these preliminary signals to determine appropriate transmission timing and content, avoiding simultaneous transmissions that would cause collisions. This proactive coordination reduces collision risks while maintaining data transmission quality.
Solution Approach 2:
The feedback mechanism provides real-time information about transmission status and channel conditions to both UEs. This feedback enables dynamic adjustment of transmission parameters and timing, allowing the system to avoid collision-prone periods and optimize data transmission quality simultaneously.
3Loss of information
If sensor raw data sharing is implemented, then information availability is improved, but device complexity increases
Solution Approach 1:
The patent segments the sensor raw data sharing process into distinct functional components: data publishing, data subscription, data transmission, and congestion control. Each component is handled by specific protocol mechanisms, making the complex information sharing process manageable and systematic. This segmentation reduces the operational complexity for individual UEs while maintaining comprehensive information availability.
Solution Approach 2:
The patent introduces intermediary mechanisms including message queues, subscription tables, and congestion control entities that mediate between data producers and consumers. These intermediaries coordinate the complex interactions between multiple UEs, managing information flow and reducing the direct complexity of peer-to-peer data sharing while maintaining high information availability.
