Vehicle Beacon Guidance for Lost Hiker Return
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Casual hikers often get lost in wilderness areas due to lack of planning and inadequate equipment, and may face emergencies like sprained ankles, power loss, or severe weather, making it difficult for them to find their way back without modern navigation tools or communication.
Innovation Solution
A vehicle equipped with processors that can detect a user's absence and trigger alert actions, such as lighting and sound signals, to guide the user back or contact emergency services, using onboard and remote computing systems for navigation and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a hiker uses only basic equipment (food and cellular phone), then the equipment weight and cost are reduced, but the ability to navigate and communicate in wilderness areas deteriorates
Solution Approach 1:
The vehicle acts as an intermediary beacon system between the hiker and emergency services. The vehicle monitors the hiker's location via GPS, communicates status to remote servers, and can trigger alerts or provide directional guidance to the hiker, thereby compensating for the hiker's lack of sophisticated navigation equipment
Solution Approach 2:
The system enables self-service monitoring where the vehicle automatically tracks the hiker's position, detects anomalies (such as failure to return by expected time), and initiates alert protocols without requiring the hiker to carry or operate complex navigation or communication devices
2Device complexity
If a hiker ventures into wilderness areas without sophisticated GPS equipment and satellite phones, then equipment cost and complexity are reduced, but the ability to be found and assisted in emergencies deteriorates
Solution Approach 1:
The vehicle serves as a mediator that bridges the gap between the hiker's simple equipment and emergency services. The vehicle's onboard system monitors hiker location, communicates with remote servers, and can alert emergency services or provide guidance to the hiker, effectively compensating for the hiker's lack of sophisticated emergency communication devices
Solution Approach 2:
The system performs preliminary monitoring and detection actions before emergencies occur. The vehicle continuously tracks the hiker's position and can detect anomalies such as failure to return by expected time, enabling early intervention and alerting emergency services before the situation becomes critical
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 vehicle system effectively assists lost hikers by providing guidance and emergency support, ensuring their safe return even without modern navigation tools, by leveraging its computing and communication capabilities.
Implementation Method 1
scan for wireless signals associated with a device correlated to the user and, responsive to a failure to detect the device
Data Source
AI summary
A vehicle determines that a trigger state designated for user assistance for a user traveling away from a vehicle has occurred. The vehicle determines that an alert action to be taken, defined in conjunction with the trigger state and determines that a user has not returned to a vehicle based on a failure to detect a user wireless device. The vehicle automatically executes the alert action responsive to the trigger state occurrence and failure to detect the user device.
