Dynamic Safety Guidance System for Rescue Route Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complex building systems like hospitals, refineries, and airports, rescue workers face difficulties in orienting themselves during emergencies due to intricate infrastructure, leading to delays in rescue operations, as existing safety guidance systems are inflexible and struggle to adapt to unforeseen events.
Innovation Solution
A safety guidance system that integrates a hazard warning system with deployable signaling means to mark both escape and deployment routes, allowing for dynamic route adjustments via a control panel, utilizing a combination of optical and acoustic signals, and communication with hazard alarm systems to optimize rescue pathways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a fully automatic safety guidance system is used to calculate and mark escape routes, then the system can operate autonomously without manual intervention, but it becomes difficult to adapt the route to unforeseen events or changing rescue tasks
Solution Approach 1:
The system transitions from a static, fully automatic route calculation to a dynamic system where routes can be adjusted in real-time. The control panel enables rescue workers to manually modify the calculated escape routes based on changing conditions, making the system adaptable while retaining automated assistance.
Solution Approach 2:
The control panel serves as an intermediary between the automated system and the rescue worker. It allows the worker to intervene in the automated route calculation process, adjusting routes based on unforeseen events while the system continues to provide automated guidance and recalculate alternative routes when needed.
2Productivity
If separate attack routes for rescue workers are calculated and displayed alongside escape routes, then rescue workers can be guided to danger points, but the system complexity increases
Solution Approach 1:
The guidance system is designed to perform multiple functions: it calculates both escape routes for evacuation and attack routes for rescue workers. The control panel and display system handle both route types, allowing the same infrastructure to serve dual purposes during emergencies.
Solution Approach 2:
The system segments different route types (escape routes and attack routes) and guides them separately through the control panel and display system. This allows independent calculation and display of each route type while using the same underlying infrastructure, managing complexity through functional segmentation.
3Loss of information
If optical and acoustic signals are used to mark routes and display information, then the guidance system can provide comprehensive information to rescue workers, but the device complexity increases
Solution Approach 1:
The system merges optical signals (display screens, illuminated signs) and acoustic signals (speakers, alarms) into a unified guidance system. Both signal types work together to provide comprehensive information about escape routes, attack routes, and hazard locations, creating a multi-sensory guidance system.

AI summary
The system (100) has an alarm system (10) and an escape signal unit (21) for indication of an escape route. The system indicates a deployment way to a place of work for rescue forces. A change-over between the indication of the escape route and the indication of the deployment way is provided by a control panel (33), which activates the indication of the deployment way. The system activates a deployment signal unit (31) depending on a deployment way process, which indicates the deployment way. The deployment way is indicated by clear pictograms.
