Viral Evacuee Identification via Handheld Proximity Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency evacuation methods, such as pen and paper solutions and electronic mustering systems, are inefficient and unreliable for quickly identifying evacuees during large-scale evacuations, often resulting in delayed reports and potential false identifications.
Innovation Solution
A method and system where emergency wardens and evacuees use handheld computing devices to read information from each other, enabling a recursive process to identify and report evacuees efficiently and reliably through a central mustering server, utilizing proximity-based communication technologies like RFID, NFC, or infrared wireless technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If handheld card readers are used to scan badges of evacuees, then identification accuracy is improved, but mustering speed deteriorates when the number of occupants increases
Solution Approach 1:
The system segments the mustering task by enabling multiple evacuees to simultaneously act as identification points. Instead of one central reader scanning all badges sequentially, each evacuee with a handheld device becomes a distributed identification node, allowing parallel processing of multiple badges across different locations within the muster point.
Solution Approach 2:
The system implements self-service by allowing evacuees to autonomously perform identification functions. When an evacuee presents their badge to another evacuee's handheld device, the identification process occurs without requiring centralized control or sequential processing, enabling the crowd to self-organize the mustering operation.
2Productivity
If mobile applications are used for self-reporting, then mustering speed is improved, but reliability deteriorates due to false reports
Solution Approach 1:
The handheld device acts as an intermediary that mediates between the badge holder and the central system. The device physically verifies the badge through proximity-based communication, creating a trusted intermediary layer that prevents false self-reporting while maintaining rapid processing speeds.
Solution Approach 2:
The system replaces manual self-reporting with automated proximity-based verification. Instead of relying on evacuees to manually input or report their presence (which can be falsified), the system uses automatic detection through proximity communication between handheld devices and badges, substituting mechanical verification for manual reporting.
3Device complexity
If pen and paper roll calls are conducted, then equipment complexity is reduced, but mustering time increases significantly
Solution Approach 1:
The system replaces manual pen-and-paper recording with electronic proximity-based detection. Handheld devices automatically detect badges through proximity communication and electronically transmit data to the central system, eliminating the need for manual writing and data entry while maintaining system accessibility.
Solution Approach 2:
The system enables continuous mustering operations by allowing parallel identification processes to occur simultaneously across multiple handheld devices. Unlike sequential pen-and-paper roll calls, the electronic system maintains continuous data flow and processing, eliminating idle time between identifications.

AI summary
A method and system for viral identification of evacuees are provided. The method is recursive and involves bringing an emergency warden and a midstream evacuee in close proximity with one another to enable a handheld computing device belonging to one of the two to read information from the other, enabling the handheld computing device to read the information, having the handheld computing device read the information to enable an identification of the midstream evacuee, providing the identifier of the midstream evacuee to a central mustering server, whereby the midstream evacuee is enabled to act as an emergency warden, and performing the method with the midstream evacuee acting as an emergency warden with respect to another evacuee before the central mustering server. The method provides the advantage of virally identifying evacuees within the confines of a muster point in an efficient and reliable manner.
