Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple ATG networks operate in overlapping geographic areas, then network coverage and bandwidth are improved, but network complexity and interference increase
Solution Approach 1:
The patent segments the ATG communication system into multiple independent network operators, each managing their own base stations and frequency spectrum. This segmentation allows parallel operation of multiple networks without requiring complete system integration, thereby increasing bandwidth capacity while managing complexity through modular independence.
Solution Approach 2:
The patent introduces an intermediary coordination mechanism that enables location information sharing between different ATG networks. This intermediary layer facilitates seamless handovers and coordinated beamforming across networks, improving coverage and bandwidth while managing interference through centralized coordination.
2Reliability
If ATG networks share location information for seamless handovers, then connectivity continuity is improved, but information security and network autonomy are compromised
Solution Approach 1:
The patent implements local quality by allowing each ATG network to independently control what location information is shared with other networks. Networks can selectively share only the minimum necessary location data for handover purposes while maintaining autonomy over their core tracking information, thus balancing connectivity continuity with information security.
Solution Approach 2:
The patent establishes preliminary agreements and protocols between networks regarding information sharing before handovers occur. These pre-defined rules specify what location information can be exchanged and under what conditions, enabling seamless handovers while maintaining information security through预先 established trust frameworks.
3Reliability
If beamforming is employed across multiple networks, then communication quality is improved, but computational requirements and energy consumption increase
Solution Approach 1:
The patent implements partial beamforming where each network applies beamforming only to the extent necessary for maintaining connectivity during handovers, rather than continuous full-scale beamforming. This partial action approach maintains communication quality during critical handover periods while reducing overall energy consumption during stable connection periods.
Solution Approach 2:
The patent employs periodic beamforming adjustments synchronized with handover events rather than continuous beamforming. Beamforming parameters are updated periodically at handover boundaries and when location changes exceed thresholds, maintaining communication quality while significantly reducing computational requirements and energy consumption compared to continuous adjustments.
