Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless communication device is configured with a preferred roaming list to select visited wireless networks, then the device can access wireless communication services in the largest possible geographic area, but the home wireless network operator must pay predetermined fees to visited wireless network operators when users roam
Solution Approach 1:
The system dynamically adjusts the preferred roaming list based on real-time network loading conditions. When a visited network exceeds its loading threshold, the system automatically removes that network from the preferred roaming list for affected users, preventing them from selecting overloaded networks. This dynamic adjustment allows the system to maintain broad geographic coverage while avoiding unnecessary roaming fees by directing users only to networks that can accommodate them.
Solution Approach 2:
The system implements a feedback mechanism where network loading information is continuously monitored and used to update preferred roaming lists. The home network operator receives loading status information from visited networks and adjusts the preferred roaming list accordingly, creating a closed-loop control system that optimizes both geographic coverage and cost management.
2Device complexity
If the preferred roaming list is statically configured, then the device has simple configuration, but the system cannot adapt to changing network loading conditions leading to potential overloading
Solution Approach 1:
The system transforms the static preferred roaming list into a dynamic configuration that automatically adapts to changing network conditions. The list is updated in real-time based on loading thresholds, maintaining configuration simplicity from the user perspective while enabling sophisticated load management through automated system adjustments.
Solution Approach 2:
The system performs self-service by automatically monitoring network loading conditions and adjusting preferred roaming lists without requiring manual intervention. The system independently makes decisions about which networks to include or exclude based on predefined loading thresholds, eliminating the need for complex manual reconfiguration while maintaining reliability.
3Ease of operation
If the system allows unlimited roaming access, then user service quality is maintained, but network overload and increased costs occur
Solution Approach 1:
The system dynamically controls roaming access by adjusting the preferred roaming list based on real-time loading conditions. When networks are under-loaded, users have broad access; when networks exceed thresholds, access is automatically restricted. This dynamic approach maintains service availability while preventing network overload and optimizing efficiency.
Solution Approach 2:
The system takes preliminary anti-action by proactively preventing users from selecting overloaded networks before they can cause further strain. By removing overloaded networks from the preferred roaming list in advance, the system prevents potential overload scenarios and maintains network efficiency while preserving service availability through alternative network selections.
