Autonomous Waterborne Rescue Device Audio Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rescue methods often fail to promptly address drowning incidents due to the victim being alone or unnoticed, or due to the rescuer lacking immediate access to a rescue object.
Innovation Solution
A waterborne autonomous rescue device and system that includes a buoyant object equipped with an audio acquisition unit, a driving module, and a central processing module capable of performing voice recognition and navigation to locate and assist a drowning person.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a traditional rescue method is used where a person manually searches for a drowning victim, then the rescuer can locate the victim, but the rescuer may not have immediate access to a rescue object and time is lost
Solution Approach 1:
The rescue device autonomously performs the rescue operation without requiring manual intervention. The audio acquisition unit detects drowning sounds, the central processing module analyzes the audio and calculates the direction of the emission source, and the driving module automatically propels the buoyant object toward the drowning person, eliminating the need for a human rescuer to manually search for and access the victim.
Solution Approach 2:
The patent replaces the mechanical action of a human rescuer searching for and approaching the drowning person with an automated system. The audio acquisition unit substitutes for human hearing, the central processing module substitutes for human decision-making, and the driving module substitutes for human physical movement, enabling rapid automated response.
2Reliability
If no autonomous rescue device is deployed, then the system remains simple, but drowning victims are often alone or unnoticed, causing golden rescue opportunities to be missed
Solution Approach 1:
The rescue device autonomously performs the rescue operation without requiring manual intervention. The audio acquisition unit detects drowning sounds, the central processing module analyzes the audio and calculates the direction of the emission source, and the driving module automatically propels the buoyant object toward the drowning person, eliminating the need for a human rescuer to manually search for and access the victim.
Solution Approach 2:
The buoyant object serves as an intermediary between the drowning person and rescue services. It automatically detects the drowning event through audio sensing, processes the information to locate the victim, and physically approaches the drowning person to provide immediate assistance, bridging the gap between the incident and professional rescue response.
3Productivity
If a buoyant object without autonomous capabilities is used, then the device is simple and inexpensive, but it cannot automatically locate or approach a drowning person
Solution Approach 1:
The patent merges multiple functional modules into a single integrated rescue device. The audio acquisition unit, central processing module, and driving module are combined in one buoyant object, enabling it to autonomously detect, process, and respond to drowning events without requiring separate systems or manual coordination.
Solution Approach 2:
The rescue device performs multiple functions within a single system: the audio acquisition unit detects drowning sounds, the central processing module analyzes audio and calculates emission source direction, and the driving module propels the object toward the victim. This multi-functional integration enables autonomous rescue operations without requiring multiple separate devices.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system increases the chances of successful rescue by automatically locating and approaching a drowning person, allowing them to cling to the buoyant object and await further assistance within a critical time frame.
Implementation Method 1
a buoyant object; The waterborne autonomous rescue device of the present invention floats in a body of water
Implementation Method 2
an audio acquisition unit, disposed on the buoyant object, and the audio acquisition unit sensing an ambient audio in a body of water
Implementation Method 3
the central processing module calculating a direction of an emission source based on the cry-out-for-help voice to control the driving module to drive the buoyant object to move forward in the direction of the emission source
Data Source
AI summary
A waterborne autonomous rescue device floats in a body of water and continuously senses an ambient audio in the body of water, and performs voice recognition on the ambient audio to recognize a cry-out-for-help voice, and calculates a direction of an emission source (e.g. a drowning person) that emits the cry-out-for-help voice, and then the waterborne autonomous rescue device will automatically move forward in the direction of the emission source, so that the drowning person can cling to the waterborne autonomous rescue device and be carried to a safe location; a waterborne autonomous rescue system includes the waterborne autonomous rescue device which is further connected to a monitoring device; a monitoring personnel can check the status of the waterborne autonomous rescue device through the monitoring device. When a drowning incident occurs, the monitoring personnel can go to a location of the waterborne autonomous rescue device to carry out subsequent rescue.
