Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 5G positioning technology is introduced for road toll collection, Internet of Vehicles, and aviation applications, then positioning capability and coverage are improved, but positioning reliability deteriorates due to lack of integrity protection function
Solution Approach 1:
The integrity protection function is segmented into independent modules: a calculation module that computes first information from sampling data and risk tolerance, and an integrity check module that performs verification. This modular approach allows the reliability improvement function to be added without requiring complete system redesign, thus managing complexity while enhancing positioning reliability through structured integrity assessment
Solution Approach 2:
The patent introduces an intermediary integrity protection mechanism that sits between the positioning system and the application layer. This intermediary layer processes sampling data through calculation modules to generate first information, then uses integrity check modules to verify positioning results against integrity thresholds, providing a buffer that enhances reliability without directly modifying the core positioning algorithms or increasing overall system complexity
2Reliability
If integrity check is performed using sampling data and risk tolerance, then positioning security is improved, but calculation complexity and processing time increase
Solution Approach 1:
The system performs preliminary actions by pre-calculating first information from sampling data using calculation modules before actual positioning results are generated. Integrity thresholds and risk tolerance parameters are pre-established, allowing the integrity check module to quickly verify positioning results against pre-computed values, thus reducing real-time processing time while maintaining security
Solution Approach 2:
The patent employs parameter changes by adjusting the granularity and sampling rate of data collection based on application requirements. The calculation module can adaptively modify parameters such as sampling frequency, data window size, and risk tolerance thresholds, allowing the integrity check to maintain high security standards while optimizing processing time for different application scenarios like road toll collection versus aviation
