Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the update cycle of the traffic digital twin is shortened to improve accuracy, then the degree of completion (accuracy) of the traffic digital twin is improved, but communication band compression and increase in communication amount occur
Solution Approach 1:
The update cycle is made dynamic rather than fixed. The determination unit adjusts the update cycle based on the degree of completion of the traffic digital twin and service requirements. When the digital twin reaches sufficient accuracy for service provision, the update cycle is extended to reduce communication volume, while maintaining high accuracy when needed for service operations.
Solution Approach 2:
The system changes the parameter of update cycle based on the degree of completion and service status. By dynamically adjusting this parameter, the system achieves high accuracy when necessary while minimizing communication overhead during stable operation phases, thus resolving the contradiction between accuracy and communication volume.
2Measurement precision
If the update cycle of the traffic digital twin is shortened to improve accuracy, then the degree of completion (accuracy) of the traffic digital twin is improved, but communication band compression occurs
Solution Approach 1:
The update cycle is dynamically adjusted based on the degree of completion and service requirements. When the digital twin achieves sufficient accuracy for service provision, the system extends the update cycle, thereby reducing communication band compression while maintaining the necessary level of accuracy for ongoing services.
Solution Approach 2:
The system dynamically changes the update cycle parameter according to the degree of completion and service status. This parameter adjustment allows the system to maintain high accuracy when needed while minimizing communication band compression during periods when the digital twin is stable and sufficient for service operations.
3Quantity of substance
If the update cycle is extended to reduce communication amount, then communication amount is reduced, but the degree of completion (accuracy) of the traffic digital twin deteriorates
Solution Approach 1:
The determination unit continuously monitors the degree of completion of the traffic digital twin and the status of service provision. Based on this feedback, the system dynamically adjusts the update cycle. When the digital twin maintains sufficient accuracy for service operations, the update cycle is extended to reduce communication amount, while automatically shortening it when accuracy deteriorates below service requirements.
Solution Approach 2:
The update cycle is made dynamic and adaptive based on real-time assessment of digital twin accuracy and service needs. This dynamic adjustment allows the system to extend the update cycle and reduce communication amount when the digital twin is sufficiently accurate, while preventing accuracy deterioration by shortening the cycle when needed.
4Loss of energy
If the update cycle is extended to reduce communication band compression, then communication band compression is reduced, but service provision may be interrupted
Solution Approach 1:
The determination unit uses feedback from service status and digital twin completion degree to dynamically adjust the update cycle. The system extends the update cycle to reduce communication band compression only when the digital twin maintains sufficient accuracy for uninterrupted service provision, thereby preventing service interruption while achieving communication efficiency.
Solution Approach 2:
The update cycle parameter is dynamically changed based on service requirements and digital twin accuracy. This ensures that communication band compression is reduced only when it does not compromise service continuity, maintaining reliability while optimizing communication resource usage.
