Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple wireless networks are available for different services, then service quality and transmission efficiency are improved, but network selection complexity and device complexity increase
Solution Approach 1:
The patent segments the network selection process by dividing services into different categories (e.g., real-time services, non-real-time services) and mapping each category to specific wireless networks. This segmentation allows the terminal to automatically select appropriate networks based on service type, reducing selection complexity while maintaining high transmission efficiency for each service category.
Solution Approach 2:
The patent changes the parameter of network selection from manual user input to automatic system-based selection using priority information and service characteristics. By transforming the selection criterion from subjective user preference to objective parameter matching (service category to network type), the system reduces complexity while optimizing transmission efficiency.
2Reliability
If automatic network handover is implemented to maintain continuous service, then service reliability is improved, but control complexity and measurement overhead increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring priority information for different wireless networks based on service characteristics before actual handover is needed. The terminal stores this priority information and automatically uses it during network selection, eliminating the need for complex real-time handover decisions and reducing control complexity while ensuring reliable service continuity.
Solution Approach 2:
The terminal performs self-service by autonomously selecting networks based on pre-stored priority information and service characteristics without requiring continuous network controller intervention. This autonomous selection mechanism simplifies handover control complexity while maintaining service reliability through consistent automatic decisions.
3Use of energy by moving object
If network resources are allocated based on service characteristics, then energy efficiency is improved, but system complexity and configuration overhead increase
Solution Approach 1:
The patent changes the resource allocation parameter from dynamic real-time adjustment to static pre-configured priority mapping. By establishing fixed priority relationships between service categories and network types before operation, the system achieves energy efficiency through optimized resource allocation without introducing complex dynamic control mechanisms.
Solution Approach 2:
The patent introduces dynamics at the policy level by allowing priority information to be updated based on changing service characteristics or network conditions, while maintaining simplicity at the execution level. This layered dynamics approach enables energy-efficient resource allocation through policy adaptation without complicating the terminal's real-time decision-making process.
