Hologram-Based Emergency Evacuation Guidance System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current building fire alarm systems provide limited assistance to evacuees beyond triggering an alarm, lacking effective guidance to safely exit the building during a fire.
Innovation Solution
A system comprising fire detectors, a fire panel, and hologram systems that communicate evacuation information to direct evacuees to the nearest exit, with human presence detectors and wireless communication to track individuals and adjust hologram visibility based on smoke attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current fire alarm systems only trigger alarms, then the system complexity is low, but the evacuation guidance effectiveness is insufficient
Solution Approach 1:
The system segments evacuation guidance by generating separate holograms for different evacuation routes and locations. Each hologram system independently displays route information for its specific area, allowing parallel evacuation guidance across multiple zones without requiring a single complex centralized control system.
Solution Approach 2:
Hologram systems serve as intermediaries between the fire detection system and evacuees. Instead of directly providing complex verbal instructions, the system uses visual holographic projections to convey evacuation routes and safety information, making the guidance more intuitive and effective while maintaining manageable system complexity.
2Loss of information
If hologram systems are added to provide evacuation guidance, then the evacuation information delivery is improved, but the device complexity increases
Solution Approach 1:
The system uses holographic projections to create visual copies of evacuation route information and safety instructions. These holographic copies convey complex evacuation guidance without requiring physical signage or manual instruction, reducing information loss while adding only moderate device complexity through the hologram systems.
3Measurement precision
If the system tracks individual locations using human presence detectors, then the evacuation guidance precision is improved, but the device complexity and cost increase
Solution Approach 1:
Human presence detectors provide feedback on evacuee locations to the fire panel, which then adjusts hologram projections to guide individuals along appropriate evacuation routes. This feedback loop enables precise, location-aware evacuation guidance without requiring overly complex tracking systems, as the system only needs to know general zone locations rather than precise individual positions.
