Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic network switching is implemented between WLAN and WWAN, then connectivity availability is improved, but data stalls occur during critical transactions
Solution Approach 1:
The system performs preliminary evaluation of network conditions and application criticality before switching occurs. By assessing SNR thresholds, encryption status, and application whitelisting in advance, the system prevents switching during critical transactions, thereby eliminating data stalls while maintaining connectivity availability.
Solution Approach 2:
The system continuously monitors network conditions and provides feedback to the switching mechanism. By evaluating real-time SNR values, encryption status, and active application states, the system dynamically adjusts switching decisions to prevent data stalls during critical operations while maintaining seamless connectivity.
2Adaptability or versatility
If network switching occurs in overlapping coverage areas, then connectivity options are increased, but link quality deteriorates
Solution Approach 1:
The system applies different switching criteria to different network conditions and applications. By evaluating SNR thresholds specific to each network, encryption status of individual connections, and criticality of active applications, the system maintains high link quality while providing multiple connectivity options in overlapping coverage areas.
Solution Approach 2:
The system changes switching parameters based on network conditions and application requirements. By adjusting SNR thresholds, evaluating encryption status, and modifying switching behavior based on application whitelisting, the system optimizes link quality while maintaining connectivity versatility in overlapping coverage areas.
3Productivity
If frequent network switching is performed, then optimal network selection is achieved, but user experience deteriorates
Solution Approach 1:
The system performs preliminary assessment of network conditions and application criticality before initiating switching. By evaluating SNR thresholds, encryption status, and application whitelisting in advance, the system minimizes unnecessary switching events, thereby maintaining network optimization while preserving seamless user experience.
Solution Approach 2:
The system continuously monitors network conditions and provides feedback to control switching frequency. By evaluating real-time SNR values, encryption status, and active application states, the system optimizes network selection while preventing excessive switching that would degrade user experience.
