Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional emergency response systems lack immediate and personalized information dissemination to individuals affected by emergencies and rely on approximate data from witnesses, failing to provide timely and accurate information for effective response.
Innovation Solution
An interactive emergency information and identification system using a processor and database to define geo-fences around emergency locations, inform individuals via their devices, and collect feedback, which includes location determination through multilateration, GPS, and WiFi positioning, enabling personalized emergency instructions and data sharing with agencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional surveillance systems are deployed to detect affected persons during emergencies, then measurement precision of emergency situation is improved, but device complexity and investment cost increase significantly
Solution Approach 1:
The patent uses mobile devices (smartphones, tablets) that individuals already possess as copies of surveillance functionality. Instead of deploying expensive fixed surveillance infrastructure, the system leverages the cameras, GPS, and communication capabilities of personal devices to collect and transmit emergency situation data, thereby achieving detection accuracy without the complexity and cost of traditional surveillance systems
Solution Approach 2:
The system enables affected individuals to self-report their status and location through mobile devices. Individuals automatically become sensors and data sources by using their own devices to provide real-time information about the emergency situation, eliminating the need for external surveillance infrastructure while maintaining high measurement precision
2Ease of operation
If radio communication systems are used for emergency response, then ease of operation is improved, but loss of information increases due to reliance on approximate witness data
Solution Approach 1:
The system implements two-way communication where emergency response agencies receive real-time data from affected individuals via mobile devices, and individuals receive personalized instructions and information in return. This feedback loop ensures accurate, up-to-date information flows both ways, eliminating the one-way approximate reporting inherent in traditional radio systems
Solution Approach 2:
The system pre-configures mobile devices with emergency applications and establishes communication channels before emergencies occur. Geo-fences are pre-defined, and individuals are pre-registered in the system, enabling immediate accurate data collection from the moment an emergency begins, rather than relying on later witness recollections
3Area of stationary object
If traditional emergency information systems are implemented, then coverage area is improved through broadcast media, but loss of time increases due to lack of immediate personalized information delivery
Solution Approach 1:
The system segments the general emergency broadcast into personalized, location-specific information delivered to individual mobile devices within geo-fenced areas. Instead of one-size-fits-all media broadcasts, the system divides the coverage area into discrete geo-location zones and delivers tailored information to each individual based on their precise location and situation, achieving both wide coverage and immediate personalized delivery
Solution Approach 2:
The system adds the dimension of precise geo-location tracking and personalized routing to traditional emergency broadcasting. By overlaying geographic information system (GIS) data with mobile device locations, the system delivers information along new spatial-temporal pathways directly to individuals in real-time, bypassing the delays of traditional media distribution channels

AI summary
Provided is a method for interactive emergency information and identification. The method may comprise receiving a notification concerning an emergency situation. The notification may include a location of the emergency situation. A geo-fence associated with the location of the emergency situation can be defined based on the location of the emergency situation. Additionally, location information associated with the locations of a plurality of user devices is received, and a position of an individual within the geo-fence is determined based on the location information of the user device associated with individual. The individual may be informed about the emergency situation via a user interface of the user device. Furthermore, functionality for a user to give feedback is provided to the individual.
