Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensing services are provided in 5G systems for applications like autonomous driving and smart cities, then the usefulness and applicability of the system is improved, but the device complexity and network configuration complexity increase due to unclear core network configuration and interface definitions
Solution Approach 1:
The patent segments the sensing service provision into distinct functional components: external system requests, core network sensing service configuration, network function selections, and information exchange interfaces. This segmentation clarifies the previously unclear core network configuration by defining specific network functions (NFs) and their selection criteria, thereby reducing configuration complexity while maintaining service versatility
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of defined network functions and standardized interfaces that mediate between external systems and the core network. This intermediary layer provides clear configuration rules and selection procedures for network functions, simplifying the overall system complexity while enabling diverse sensing applications
2Loss of information
If information is exchanged frequently to provide timely sensing data, then the information freshness and service quality is improved, but the energy consumption and network load increase
Solution Approach 1:
The patent implements dynamic information exchange by allowing the determination of appropriate response frequencies based on detection conditions and target characteristics. Rather than using fixed frequent updates, the system dynamically adjusts information exchange timing to match actual sensing needs, maintaining information freshness while reducing unnecessary energy consumption during periods of low change
Solution Approach 2:
The patent changes the parameter of information exchange frequency based on detection conditions, target types, and service requirements. By adjusting this parameter dynamically rather than maintaining constant high-frequency exchange, the system achieves timely information provision while optimizing energy consumption and network load
3Measurement precision
If detection frequency is increased to improve sensing accuracy, then the measurement precision is improved, but the productivity and resource efficiency deteriorate due to excessive data processing
Solution Approach 1:
The patent applies local quality by determining detection frequencies and information exchange parameters based on specific detection conditions, target characteristics, and service requirements rather than using uniform high-frequency detection across all scenarios. This localized optimization maintains high sensing accuracy where needed while improving overall resource processing efficiency
Solution Approach 2:
The patent implements partial action by adjusting detection frequency to match actual sensing needs rather than continuously operating at maximum frequency. The system performs detection and information exchange at the appropriate level required by each specific condition, avoiding excessive data processing while maintaining necessary measurement precision
