Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack the ability to effectively control and restrict the flight of unmanned aerial vehicles (UAVs) within or near irregularly shaped regions, such as those around airports or important buildings, necessitating improved flight restriction zones and associated response measures.
Innovation Solution
The implementation of irregularly shaped flight restriction zones defined by flight restriction strips, which assess the location and movement characteristics of UAVs relative to these zones, and direct appropriate flight response measures using processors to ensure compliance with flight restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If regular or simple geometric shapes are used for flight restriction zones, then the system complexity is reduced and ease of operation is improved, but the ability to accurately represent irregularly shaped restricted areas (such as airports or important buildings) is worsened
Solution Approach 1:
The patent divides irregularly shaped flight restriction zones into multiple straight-line segments or polygonal boundaries. Each segment represents a portion of the overall restricted area, allowing complex shapes to be constructed from simpler linear elements. This segmentation enables accurate representation of irregular boundaries while maintaining computational tractability for UAV navigation systems.
Solution Approach 2:
The patent transitions from two-dimensional geometric shapes to three-dimensional flight restriction volumes by adding altitude dimensions. Flight restriction zones are defined not only by horizontal boundaries but also by vertical limits, creating polyhedral restriction volumes that more accurately represent real-world airspace constraints around airports and important buildings.
2Manufacturing precision
If complex irregularly shaped flight restriction zones are implemented, then the precision of flight restriction zone representation is improved, but the system complexity and computational requirements are worsened
Solution Approach 1:
The patent divides irregularly shaped flight restriction zones into multiple straight-line segments or polygonal boundaries. Each segment represents a portion of the overall restricted area, allowing complex shapes to be constructed from simpler linear elements. This segmentation enables accurate representation of irregular boundaries while maintaining computational tractability for UAV navigation systems.
Solution Approach 2:
The patent replaces complex geometric calculations with simplified distance-based assessments. Instead of calculating precise positions relative to irregular polygon boundaries, the system assesses whether the UAV is within a flight restriction zone by measuring distance from defined boundaries, using simpler computational geometry operations that reduce processing requirements.
3Device complexity
If manual monitoring and control of UAVs near restricted areas is used, then the system complexity is reduced, but the productivity and response time of flight restriction enforcement are worsened
Solution Approach 1:
The patent implements automated flight restriction enforcement where the UAV system itself performs monitoring and compliance assessment. The UAV's navigation system automatically assesses its location relative to flight restriction zones, determines compliance status, and executes appropriate response measures without external human intervention. This self-service approach dramatically improves enforcement efficiency and response time.
Solution Approach 2:
The patent establishes a continuous feedback loop where the UAV's navigation system constantly monitors position, assesses compliance with flight restrictions, and adjusts flight control accordingly. Real-time feedback from location sensors feeds into the compliance assessment algorithm, which immediately generates response measures that are fed back to the flight control system, creating a closed-loop automated enforcement mechanism.

AI summary
Systems, methods, and devices are provided for controlling an unmanned aerial vehicle (UAV) associated with flight response measures. The flight response measure may be generated by assessing one or more flight-restriction strips, assessing at least one of a location or a movement characteristic of the UAV relative to the one or more flight-restriction strips, and directing, with aid of one or more processors, the UAV to take one or more flight response measures based on at least one of the location or movement characteristic of the UAV relative to the one or more flight-restriction strips.
