UAV Emergency Evacuation via Position Comparison

Solution Overview

Problem

Conventional technologies for controlling unmanned aerial vehicles during emergencies do not account for multiple positions such as the vehicle's current location, the manipulator's location, and the flight route, leading to potential uncontrollability or interference with rescue operations.

Innovation Solution

An unmanned aerial vehicle equipped with a memory for storing position information, a receiver for emergency warnings, and a processor that compares target regions with its own and manipulator positions to autonomously select and execute appropriate evacuation actions, including changing flight routes or landing, based on detected emergency warnings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the unmanned aerial vehicle uses conventional emergency control methods that only consider the vehicle's current position, then the control system is simple, but the vehicle may interfere with rescue operations or become uncontrollable when the manipulator is affected by the disaster

Engineering Contradiction:

Improveemergency evacuation reliabilityVSAvoidcontrol system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary comparison of the emergency target region with both the unmanned aerial vehicle's current position and the manipulator's current position before executing evacuation actions. This advance assessment allows the system to select appropriate evacuation strategies (such as returning to manipulator position or evacuating to a different location) based on pre-evaluated conditions, improving reliability without requiring complex real-time decision-making during the emergency

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The control system introduces an intermediary comparison mechanism that evaluates the relationship between the emergency target region, vehicle position, and manipulator position. This intermediary layer processes the spatial relationships and determines the appropriate evacuation action, bridging the gap between simple position monitoring and complex emergency response decision-making

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the unmanned aerial vehicle autonomously compares target region with both vehicle position and manipulator position, then the evacuation action is appropriate and safe, but the processing complexity increases

Engineering Contradiction:

Improveevacuation action adaptabilityVSAvoidprocessor complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The comparison process is segmented into distinct evaluation steps: first comparing the emergency target region with the unmanned aerial vehicle's current position, then comparing the target region with the manipulator's current position. This segmentation allows the processor to handle complex spatial relationships through a series of simpler, modular comparison operations, improving adaptability while managing processing complexity through structured decomposition

Inventive Principle:

Principle #1Segmentation

3Speed

If the unmanned aerial vehicle does not consider manipulator position during emergency, then the system response is fast, but the vehicle may become uncontrollable or interfere with rescue operations

Engineering Contradiction:

Improveemergency response speedVSAvoidoperation safety

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The system performs preliminary comparison of the emergency target region with both the unmanned aerial vehicle's current position and the manipulator's current position before executing evacuation actions. This advance assessment allows the system to select appropriate evacuation strategies (such as returning to manipulator position or evacuating to a different location) based on pre-evaluated conditions, improving reliability without requiring complex real-time decision-making during the emergency

AI summary

An unmanned aerial vehicle includes: a memory that stores first information acquired and second information acquired, the first information indicating the current position of the unmanned aerial vehicle, the second information indicating the current position of a manipulation device that transmits a command to remotely manipulate the unmanned aerial vehicle; a receiver that receives information transmitted from a transmission source, the information including an emergency warning; a processor; and a controller that controls the unmanned aerial vehicle. The processor compares a target region which is indicated in the information and for which the emergency warning is intended and the current position of the unmanned aerial vehicle and compares the target region and the current position of the manipulation device. The controller evacuates the unmanned aerial vehicle in accordance with the results of the comparisons.
