Dynamic Evacuation Routing for Refuge Guide Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire escape guidance systems lack the ability to dynamically adjust evacuation routes based on disaster situations and do not effectively assist individuals with poor physical agility, often leading to incorrect escapes and increased casualties in complex building layouts.
Innovation Solution
A refuge guide system comprising a central server, refuge guide devices, and wireless communication units that transmit and execute updated evacuation plans, incorporating sensors and transport units to guide users safely and potentially extinguish fires, while accommodating different user abilities through personalized route planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-recorded voice indicators are used for fire escape guidance, then the system is simple to implement, but it lacks the capability to dynamically adjust evacuation routes according to disaster situations
Solution Approach 1:
The system transitions from static pre-recorded voice indicators to dynamic real-time guidance. The central server continuously receives fire monitoring data, calculates optimal evacuation routes dynamically, and updates guidance information to refuge guide devices in real-time, allowing the system to adapt to changing disaster situations.
Solution Approach 2:
A central server is introduced as an intermediary between fire monitoring devices and refuge guide devices. The server processes fire information, calculates evacuation routes using map data, and communicates updated guidance to guide devices, enabling dynamic route adjustment without requiring complex local processing at each guide device.
2Loss of information
If loudspeaker broadcast systems are used, then the coverage area is large, but they cannot provide detailed disaster location and escape direction information
Solution Approach 1:
The system provides localized and personalized evacuation guidance to each refuge guide device based on its specific position and the fire location. Instead of uniform broadcast messages, each device receives tailored route guidance with detailed information about disaster location, type, and specific escape directions relevant to that user's situation.
Solution Approach 2:
The system establishes a feedback loop where refuge guide devices report their positions and status to the central server, which then provides updated guidance information. This two-way communication ensures users receive accurate, location-specific information about disaster conditions and escape routes.
3Adaptability or versatility
If standard evacuation routes are used for all users, then the system is easy to operate, but it cannot accommodate individuals with poor physical agility
Solution Approach 1:
The system provides differentiated evacuation routes and guidance based on user characteristics stored in user setting data. For users with poor physical agility, the system calculates and provides alternative routes that are more accessible and less physically demanding, while maintaining standard routes for able-bodied users.
Solution Approach 2:
User setting data including physical ability information is pre-configured and stored in the system before emergencies occur. When a disaster happens, the central server immediately retrieves this data and provides appropriately tailored evacuation routes without requiring real-time assessment or complex processing during the emergency.
