Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If special equipment is used for benchmarking mobile radio networks, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by enabling the vehicle's existing telematics unit to perform network benchmarking functions that traditionally required specialized equipment. The telematics unit, already present for vehicle communication, is configured to execute benchmarking measurements across multiple mobile radio networks, eliminating the need for separate dedicated benchmarking devices while maintaining measurement accuracy.
Solution Approach 2:
The system implements self-service by allowing the vehicle's own telematics unit to conduct network performance measurements without external specialized equipment. The telematics unit autonomously performs measurements, collects data, and communicates results, making the vehicle itself the measurement device rather than requiring external benchmarking equipment.
2Productivity
If multiple mobile radio networks are benchmarked simultaneously, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by implementing a flexible network selection mechanism that can dynamically switch between multiple mobile radio networks for benchmarking. The system can adaptively choose which networks to measure based on availability, configuration, and measurement requirements, enabling efficient multi-network benchmarking without rigid complex infrastructure.
Solution Approach 2:
The system implements preliminary action by pre-configuring the telematics unit with multiple SIM cards corresponding to different mobile radio networks before benchmarking begins. This advance preparation allows the system to immediately start benchmarking across multiple networks without complex real-time configuration, improving productivity while managing complexity through upfront setup.
3Measurement precision
If performance data is collected across multiple networks, then measurement precision is improved, but loss of information increases
Solution Approach 1:
The patent applies segmentation by organizing performance data collection into structured segments for each mobile radio network. The system separates measurement data by network identifier, creating distinct data streams for each network while maintaining overall coherence. This segmentation prevents information loss by ensuring systematic capture and organization of performance metrics across multiple networks.
Solution Approach 2:
The system implements feedback mechanisms that continuously monitor data collection quality and provide feedback on information completeness. This allows the system to detect and correct potential data loss scenarios, ensuring that performance measurements across multiple networks maintain high precision through active monitoring and adjustment.
