Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional ground-based surveillance systems are used to monitor airspace, then coverage area is limited and detection capability is insufficient, but deploying more systems increases cost and complexity
Solution Approach 1:
The patent transitions from ground-based two-dimensional surveillance to airborne three-dimensional monitoring by deploying a blimp in the sky. This dimensional change enables a single mobile system to cover a vast three-dimensional airspace volume, eliminating the need for multiple fixed ground stations and significantly expanding monitoring coverage area while reducing overall system complexity.
Solution Approach 2:
The blimp-based system is autonomous and self-positioning, using its own sensors and processing capabilities to detect, track, and identify unauthorized UAVs without requiring external ground control. This self-service capability reduces the need for complex ground-based support infrastructure and enables flexible deployment in various geographic locations.
2Measurement precision
If multiple cameras and sensors are deployed to improve detection accuracy, then unauthorized UAV detection capability improves, but device complexity and energy consumption increase
Solution Approach 1:
The patent integrates multiple camera systems, location sensors, and processing units into a single unified blimp platform. By merging these components into one mobile unit, the system achieves high detection accuracy through multi-sensor fusion while avoiding the complexity of coordinating multiple separate ground-based systems. The integrated design allows centralized processing and control of all sensors.
Solution Approach 2:
The blimp serves multiple functions simultaneously: it acts as a mobile platform for cameras, a positioning station for location sensors, and a processing center for AI-based analysis. This multi-functionality reduces the need for separate dedicated systems for each function, thereby reducing overall device complexity while maintaining high detection precision.
3Measurement precision
If AI-based image signature comparison is implemented to distinguish authorized and unauthorized UAVs, then identification accuracy improves, but processing time and computational resources increase
Solution Approach 1:
The system pre-establishes and stores image signatures of authorized UAVs in a database before actual detection occurs. When a UAV is detected, the system only needs to compare the captured image against this pre-existing database of authorized signatures, rather than performing complex analysis from scratch. This preliminary preparation significantly reduces real-time processing time while maintaining high identification accuracy.
Solution Approach 2:
Instead of analyzing every pixel and feature of detected UAVs in detail, the system creates simplified image signatures (visual fingerprints) that capture essential identifying characteristics. By working with these compressed representations rather than full images, the system achieves accurate identification with reduced computational load and faster processing speeds.

AI summary
An autonomous unmanned aerial vehicle detecting system for monitoring a geographic area includes an unmanned blimp adapted to hover in air, at least one camera mounted on the blimp to scan at least a portion of the geographic area, a location sensor to determine a location of the blimp, and a controller arranged in communication with blimp, the at least one camera, and the location sensor. The controller is configured to position the blimp at a desired location in the air based on inputs received from the location sensor, and monitor the geographic area based on the images received from at least one camera. The controller is also configured to detect a presence of an unmanned aerial vehicle within the geographic area based on the received images, and determine whether the detected unmanned aerial vehicle is an unauthorized unmanned aerial vehicle based on the received images.
