Refuge Guide Robot Dynamic Evacuation Routing
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.
Innovation Solution
A refuge guide system comprising a central server, refuge guide devices, and fire monitoring devices that transmit and update evacuation information in real-time, using wireless communication and positioning data to guide users to safe locations, while also incorporating fire extinguishing capabilities and adaptive routing for varying user abilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-recorded voice broadcast is used for fire escape guidance, then the system is simple to implement, but it lacks the capability to dynamically adjust evacuation routes based on disaster situations
Solution Approach 1:
The system transitions from static pre-recorded voice guidance to dynamic real-time guidance by implementing a central server that receives fire alarm information, calculates optimal evacuation routes based on current disaster locations and user positions, and continuously updates guidance instructions. This dynamic adjustment capability allows the system to adapt to changing fire situations while providing accurate real-time direction to users.
Solution Approach 2:
A central server is introduced as an intermediary component between fire monitoring devices and user devices. The server receives fire alarm information from monitoring devices, processes the data to determine disaster locations and affected areas, calculates optimal evacuation routes, and transmits guidance instructions to user devices. This intermediary architecture enables complex dynamic route adjustment functionality while keeping individual user devices relatively simple.
2Reliability
If fixed evacuation routes are provided, then the guidance system is easy to implement, but it may lead to incorrect escape directions when disaster locations change
Solution Approach 1:
The system implements feedback mechanisms where fire monitoring devices continuously detect fire alarm information and transmit it to the central server. The server uses this feedback to update disaster location data, recalculate evacuation routes, and provide real-time guidance adjustments. This feedback loop ensures that escape guidance remains accurate even as fire situations evolve, maintaining high reliability without requiring complex manual intervention.
3Adaptability or versatility
If standard evacuation routes are used for all users, then the system is simple to operate, but it lacks adaptive routing for individuals with poor physical agility
Solution Approach 1:
The system applies local quality by providing customized evacuation routes tailored to individual user characteristics. Users with poor physical agility receive specially designed routes that avoid strenuous paths, incorporate rest areas, and consider accessibility requirements. The central server automatically adjusts route recommendations based on user profiles and real-time conditions, making the system adaptable to different abilities while maintaining ease of operation through automated personalization.
