Engineering Contradiction Analysis
1Adaptability or versatility
If traditional antenna management solutions are used for HAPS, then the system structure is simple, but the wireless coverage and adaptability in hard-to-reach areas are insufficient
Solution Approach 1:
The antenna system is divided into multiple independent antenna elements that can be individually controlled and positioned. Each antenna element operates as an independent unit within the distributed array, allowing flexible configuration and adaptation to different coverage requirements without redesigning the entire system.
Solution Approach 2:
The patent implements dynamic antenna positioning where the spatial arrangement of antenna elements can be adjusted in real-time based on service requirements. The distributed antenna system on flying platforms enables dynamic reconfiguration of the antenna array geometry to optimize coverage for moving users or changing environmental conditions.
2Productivity
If dynamically positioned antennas are deployed on flying platforms, then wireless coverage and spectral efficiency are enhanced, but the system complexity and positioning control difficulty increase
Solution Approach 1:
The system incorporates feedback mechanisms where the positioning and configuration of antenna elements are continuously adjusted based on received signal quality measurements and service performance metrics. This closed-loop control enables automatic optimization of spectral efficiency while managing positioning complexity through adaptive rather than purely predetermined configurations.
Solution Approach 2:
The patent utilizes changes in spatial parameters (position, orientation, spacing) of antenna elements to optimize system performance. By dynamically adjusting these physical parameters based on service requirements and environmental conditions, the system achieves enhanced spectral efficiency without requiring complete system redesign for each scenario.
3Adaptability or versatility
If multiple antennas are selectively positioned on external surfaces and within internal volumes of flying platforms, then coverage flexibility is improved, but the manufacturing and integration complexity increase
Solution Approach 1:
The flying platform structure is designed with universal mounting interfaces and standardized antenna elements that can be configured for multiple purposes. The same basic antenna unit and mounting mechanism can serve different coverage requirements by changing only the position and orientation, not the fundamental design, thereby maintaining manufacturing simplicity while achieving coverage flexibility.
Solution Approach 2:
The patent integrates antenna elements within the internal volume of the flying platform structure, nesting the antenna system within the platform's existing framework. This nested arrangement allows antennas to be positioned both internally and externally without requiring separate structural systems, reducing overall manufacturing complexity while maintaining deployment flexibility.
4Reliability
If intelligent reflection surfaces are deployed on flying platforms, then signal propagation is optimized, but the device complexity and control difficulty increase
Solution Approach 1:
The intelligent reflection surface acts as an intermediary element that passively optimizes signal propagation by reflecting and directing electromagnetic waves. Rather than requiring active control of multiple individual signal paths, the IRS provides a single surface-level control mechanism that mediates between the antenna elements and the propagation environment, reducing control complexity while improving signal reliability.
