Unmanned Aircraft Wind Barrier Control for Restricted Area Entry Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security surveillance systems using unmanned aircraft struggle to prevent moving objects from entering specific areas, as they rely solely on intimidation through alarming devices, which are ineffective in preventing movement and can lead to increased weight and limited application beyond security usage.
Innovation Solution
An unmanned aircraft equipped with sensors to detect moving objects and area information, using its flight operation to generate wind and position itself between the object and the restricted area, thereby preventing entry by creating a barrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alarming devices are used to intimidate suspicious persons, then security surveillance capability is improved, but the aircraft weight increases and application versatility is limited
Solution Approach 1:
The unmanned aircraft utilizes its own flight capability to generate wind that acts as a barrier against moving objects. The aircraft's propulsion system, originally designed for flight, is repurposed to create a protective wind barrier, eliminating the need for separate alarming or blocking devices and thus avoiding additional weight.
2Reliability
If alarming devices are used to intimidate suspicious persons, then security surveillance capability is improved, but application versatility is limited
Solution Approach 1:
The patent makes the unmanned aircraft multi-functional by enabling it to perform both security surveillance and physical barrier functions using its flight capability. The same flight system that provides mobility also generates the wind barrier, allowing the aircraft to be applied in various scenarios including security, area protection, and access control without requiring specialized equipment for each function.
3Reliability
If the aircraft moves to position itself between the moving object and restricted area, then entry prevention capability is improved, but energy consumption increases
Solution Approach 1:
Once the unmanned aircraft positions itself between the moving object and the restricted area, it maintains continuous flight operation to generate a sustained wind barrier. This continuous action ensures reliable entry prevention, and the aircraft can remain in position as long as energy is available, providing ongoing protection without requiring periodic repositioning or additional energy-intensive mechanisms.

AI summary
An unmanned aircraft includes: a sensor (person detection sensor) and so forth) that performs sensing of an external environment of the unmanned aircraft; a detector (suspicious person identifier) that detects a moving object based on a result of the sensing performed by the sensor; an obtainer (movement prohibition position determiner) that obtains area information indicating an area, entry to which by the moving object is undesirable; and a flight controller that causes the unmanned aircraft to move to a position between the moving object and the area indicated by the area information, based on a positional relation between the moving object and the area, and fly at the position that is a destination position.
