Emergency Broadcasting Anchor Access Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During emergencies in facilities, evacuation routes may become blocked or impassable, leading to confusion and increased danger as individuals may not be able to determine safe alternate routes, potentially moving towards the emergency instead of away from it.
Innovation Solution
An emergency broadcasting system utilizing anchor access points with sensors to detect emergencies and send messages to location tags, determining a projected path of the emergency and alerting users with threat levels and safe evacuation routes to avoid the affected area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional static evacuation routes are used, then the evacuation system is simple to implement, but the routes may become blocked or impassable during emergencies, leading to increased danger and confusion
Solution Approach 1:
The patent implements dynamic evacuation routing where the system continuously monitors emergency conditions and updates evacuation routes in real-time. Location tags receive updated directional guidance as the emergency situation evolves, transforming static evacuation plans into adaptive, dynamic pathways that respond to changing conditions.
Solution Approach 2:
The system incorporates feedback mechanisms where sensors detect emergency conditions and feed this information back to the central controller, which then updates location tags with new evacuation directions. This closed-loop feedback ensures evacuation routes remain valid and safe throughout the emergency event.
2Loss of information
If real-time emergency broadcasting is implemented, then users receive accurate threat level information and dynamic routing, but the system complexity and cost increase
Solution Approach 1:
The system segments information delivery by targeting specific location tags with customized evacuation instructions based on their precise location and threat level. Rather than broadcasting to all users uniformly, the system divides the facility into zones and provides tailored guidance to each group, improving information accuracy while managing complexity through localized communication.
Solution Approach 2:
Location tags serve multiple functions: they provide location tracking, receive emergency alerts, display threat levels, and guide evacuation routing. This multi-functionality consolidates what would otherwise require separate systems into a single universal device, reducing overall system complexity while maintaining comprehensive information delivery.
3Measurement precision
If sensors are deployed throughout the facility to detect emergencies, then the detection accuracy and response time improve, but the system cost and maintenance requirements increase
Solution Approach 1:
The patent combines multiple sensor types (smoke, heat, gas detection) and communication functions into integrated access points that serve both monitoring and guidance roles. This merging reduces the number of discrete components needed compared to separate sensor networks and communication systems, lowering overall complexity while maintaining high detection accuracy.
