Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single SIM card and RF unit are used, then the device structure is simple, but communication reliability deteriorates due to potential failures in the wireless communication module, SIM card, or cellular data network
Solution Approach 1:
The patent divides the communication system into multiple independent SIM cards and RF units, where each SIM card is associated with a specific RF unit. This segmentation allows the system to switch between different communication paths when one fails, thereby improving reliability without requiring complete system redundancy.
Solution Approach 2:
The patent implements a mechanism that proactively monitors the status of SIM cards and RF units, and automatically switches to backup components before complete communication failure occurs. This beforehand cushioning approach ensures continuous communication by preparing alternative paths in advance.
2Reliability
If multiple SIM cards and RF units are used, then communication reliability improves through redundancy, but device complexity increases
Solution Approach 1:
The patent designs the system so that multiple SIM cards and RF units serve the same communication function, with each component being interchangeable. This multi-functionality approach allows the system to maintain reliability through redundancy while managing complexity by treating all SIM cards and RF units as equivalent functional units.
Solution Approach 2:
The system automatically monitors the status of SIM cards and RF units, and performs self-switching when failures are detected, without requiring external intervention. This self-service mechanism reduces the operational complexity burden on users while maintaining high reliability.
3Productivity
If automatic SIM card switching based on multiple parameters is implemented, then network performance is optimized, but control complexity increases
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors multiple parameters including geographical location, data usage, signal quality, time, duration of usage, billing cycle information, and network performance. Based on this feedback, the system automatically selects the optimal SIM card and RF unit combination, thereby optimizing network performance through data-driven decisions.
Solution Approach 2:
The system pre-configures multiple SIM cards with different network profiles and operators, and pre-establishes switching criteria based on various parameters. When switching conditions are met, the system executes pre-planned switching actions, which simplifies real-time control complexity while maintaining optimized network performance.
