Avalanche Rescue Drone with Electronic Device Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for locating avalanche victims are inefficient, often resulting in delayed discovery due to the large area to be searched and the difficulty in identifying buried individuals under heavy snow, leading to high mortality rates from asphyxiation.
Innovation Solution
A drone system equipped with a camera and electronic device detection capabilities is used to autonomously identify the location of avalanche victims by analyzing surface roughness and detecting electronic devices, with the ability to drop markers to guide rescuers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual searching methods (digging with hands or shovels) are used to locate avalanche victims, then the search can be performed with simple equipment, but the search speed is extremely slow and covers only a tiny fraction of the avalanche field within the critical 15-minute window
Solution Approach 1:
The patent replaces manual mechanical searching (digging with hands/shovels) with an automated drone system that uses electronic device detection technology. The drone autonomously flies over the avalanche field, detects electronic devices buried with victims using electromagnetic signals, and transmits location data to rescuers, dramatically increasing search speed from manual rates of ~2 square meters per person per minute to automated coverage of the entire 9,750 square meter field within minutes.
Solution Approach 2:
The drone system performs autonomous operation without requiring continuous human intervention. It automatically navigates the avalanche field, detects electronic devices, identifies victim locations, and transmits data back to rescuers. This self-service capability allows the system to operate independently at high speed, covering the entire search area within the critical time window without being limited by human physical constraints.
2Measurement precision
If handheld avalanche transceivers are used to search for victims, then detection capability is improved, but the high cost and difficulty of use limit widespread adoption and effective deployment
Solution Approach 1:
The patent introduces a drone as an intermediary between the avalanche field and rescuers. Instead of requiring each rescuer to operate complex handheld transceivers, the drone serves as the detection platform equipped with electronic device detection technology. This intermediary approach centralizes the detection capability while simplifying the rescuers' role to monitoring drone-transmitted location data, thereby improving both detection accuracy and ease of operation.
3Reliability
If the entire avalanche field must be searched to ensure no victims are missed, then search completeness is improved, but the large area (9,750 square meters) makes exhaustive searching impossible within the 15-minute survival window
Solution Approach 1:
The patent replaces slow manual searching with automated drone-based electronic device detection. The drone systematically covers the entire 9,750 square meter avalanche field by detecting electromagnetic signals from buried electronic devices, enabling complete search coverage within minutes rather than hours. This substitution maintains search completeness while reducing the time required from impossible to well within the critical 15-minute window.
Solution Approach 2:
The patent transitions from two-dimensional surface searching (digging through snow) to three-dimensional electromagnetic field detection. The drone detects electronic devices by sensing electromagnetic signals that penetrate the snow cover, adding a new dimensional approach to the search problem. This allows the system to locate victims throughout the volume of the avalanche field without requiring physical excavation of every square meter.

AI summary
Avalanches often trap people under the snow. Although nearly all avalanche victims survive the initial avalanche, asphyxiation will occur after about fifteen minutes if rescuers do not know where to dig to uncover avalanche victims. Drones can include unique hardware and software that enables them to search for avalanche victims and mark the locations of avalanche victims to quickly and accurately notify rescuers where to dig through the snow to save avalanche victims from asphyxiation.
