Vehicle Rescue UAV Navigation for Mountainous and Flooded Emergencies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rescue operations in mountainous or flooded areas are challenging due to increased accident probabilities and safety concerns for stranded vehicle occupants, as existing technologies lack effective and safe methods for rapid assessment and intervention.
Innovation Solution
An intelligent rescue system comprising a vehicle-mounted device and a rescue device, including sensors and an UAV, which determines the type of emergency and deploys a rescue UAV to assess and navigate to the vehicle's location, avoiding obstacles and ensuring safe communication with a global satellite search and rescue system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rescue methods are used in mountainous or flooded areas, then rescuers can directly access the vehicle, but the safety of rescuers and occupants cannot be guaranteed and rescue efficiency is reduced
Solution Approach 1:
The patent introduces a rescue device as an intermediary between rescuers and the stranded vehicle. This device includes a support component that can be deployed to stabilize the vehicle and a rescue component that provides assistance to occupants without requiring rescuers to physically enter dangerous environments. The intermediary device transfers the rescue function from human rescuers to an automated system, thereby improving safety while maintaining rescue efficiency.
Solution Approach 2:
The rescue device incorporates automatic detection and response capabilities that enable it to perform rescue operations autonomously or with minimal human intervention. The system can automatically detect vehicle status, deploy support structures, and provide rescue assistance without requiring continuous human presence or manual operation, thus improving both safety and efficiency.
2Productivity
If rescuers directly access vehicles in difficult terrains, then they can provide immediate assistance, but their safety cannot be guaranteed
Solution Approach 1:
The rescue device serves as an intermediary that delivers assistance to vehicle occupants without requiring rescuers to enter hazardous environments. The device includes automated components that can stabilize the vehicle and provide rescue functions remotely, eliminating the need for human rescuers to expose themselves to terrain-related dangers while maintaining immediate assistance capability.
Solution Approach 2:
The patent replaces the mechanical system of human rescuers physically accessing vehicles with an automated rescue device that uses mechanical actuators, sensors, and control systems to perform rescue operations. This substitution eliminates human exposure to harmful terrain factors while maintaining the ability to provide immediate assistance through automated vehicle stabilization and occupant extraction mechanisms.

AI summary
An intelligent rescue method applied to a vehicle-mounted device and an airborne rescue device to enable semi-automatic warning and rescue of a broken-down, crashed, drowned, or stranded vehicle, enables communication between the vehicle-mounted device and the rescue device. The vehicle-mounted device determines by sensors a type of emergency of a vehicle, and performs a first assistance action and sends the rescue device a distress signal corresponding to the type of the emergency of the vehicle. The rescue device receives the distress signal and takes off from an initial position of the vehicle to a target position in response to the distress signal. Once the rescue device reaches the target position, the rescue device performs a second action for assistance.
