Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data files are transmitted using large segmentation sizes to improve transmission efficiency, then productivity is improved, but the reliability of V2X message communication deteriorates due to potential disruptions in dangerous UE states
Solution Approach 1:
The patent implements dynamic segmentation size adjustment based on UE state. The segmentation size is not fixed but adapts in real-time according to the UE's operational state (safe vs. dangerous). When the UE is in a safe state, larger segmentation sizes are used to maximize data file transmission efficiency. When the UE transitions to a dangerous state, the segmentation size is reduced to prioritize V2X message communication reliability, thereby resolving the contradiction between productivity and reliability.
Solution Approach 2:
The patent changes the segmentation size parameter dynamically based on UE state conditions. By monitoring UE state and adjusting the segmentation size parameter accordingly, the system optimizes the balance between data file transmission efficiency and V2X message communication reliability. This parameter adaptation allows the system to respond to changing operational conditions and resolve the inherent contradiction between the two communication requirements.
2Reliability
If the transmission period of V2X messages is reduced to improve reliability in dangerous states, then reliability is improved, but the loss of time for data file transmission increases
Solution Approach 1:
The patent segments data files into smaller units when the UE is in a dangerous state, allowing multiple segments to be transmitted within the constraints of reduced V2X message transmission periods. This segmentation enables the system to maintain frequent V2X message transmission for reliability while still progressing data file transmission over multiple intervals, thereby mitigating the time loss that would result from strictly adhering to reduced transmission periods.
Solution Approach 2:
The patent performs preliminary assessment of UE state to determine appropriate transmission strategies. By identifying dangerous states in advance, the system can proactively adjust segmentation sizes and transmission schedules to minimize the impact on data file transmission time while ensuring V2X message reliability is maintained through appropriate transmission period adjustments.
3Adaptability or versatility
If adaptive segmentation is implemented to resolve communication degradation, then adaptability is improved, but device complexity increases due to state monitoring and dynamic adjustment mechanisms
Solution Approach 1:
The patent implements a self-service mechanism where the UE autonomously monitors its own state and automatically adjusts segmentation sizes without requiring external control or complex coordination with the network. This self-service approach improves adaptability to UE state while limiting the increase in device complexity to only the essential monitoring and adjustment logic, avoiding the need for complex external control systems.
Solution Approach 2:
The patent integrates multiple functions into the UE's existing transmission control mechanism. The same control structure that manages normal data transmission is extended to also handle state monitoring and adaptive segmentation adjustment. This multi-functionality approach improves adaptability while minimizing additional complexity by reusing existing system components rather than introducing separate dedicated systems.
