Targeted Fire Response in Multi-Tenant Dwelling Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency response systems in multi-tenant dwelling units (MDUs) face challenges due to unknown locations and intensities of hazards, leading to potential extensive damage beyond what is necessary to address the emergency.
Innovation Solution
A targeted response system utilizing multi-modal sensor data and video analytics to detect, monitor, and respond to localized emergencies in MDUs, employing smart analytics and IoT sensors to coordinate a response specific to affected sub-areas, potentially involving drone deployment and localized systems like sprinklers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a comprehensive emergency response system is installed in MDUs to detect all hazards, then the reliability of emergency detection is improved, but the extent of damage caused by the response exceeds what is necessary
Solution Approach 1:
The system divides the MDU into multiple sub-areas with individual sensors and response mechanisms. When a hazard is detected, only the specific sub-area where the hazard occurs receives the emergency response, rather than activating systems throughout the entire building. This segmentation allows reliable hazard detection while limiting damage to only the necessary area.
Solution Approach 2:
The system implements localized response mechanisms where each sub-area has its own sensors and response capabilities. The emergency response is tailored to the specific location and type of hazard detected, applying the appropriate level and type of response only where needed, thereby preventing unnecessary damage to other areas of the MDU.
2Speed
If traditional emergency response systems activate all safety systems upon hazard detection, then the speed of response is improved, but the loss of substance increases due to unnecessary water discharge from sprinklers
Solution Approach 1:
The sprinkler system is divided into zone-specific units that can be independently activated. When a hazard is detected by sensors in a particular sub-area, only the sprinklers in that specific sub-area are activated, maintaining fast response time while preventing water damage in unaffected areas of the MDU.
Solution Approach 2:
The system pre-positions sensors and response mechanisms in each sub-area, allowing for immediate localized activation upon hazard detection. This preliminary arrangement enables the system to respond rapidly to emergencies while limiting the scope of the response to only the affected area, thereby reducing unnecessary water discharge and property damage.

AI summary
Methods and systems including computer programs encoded on a computer storage medium, for receiving, for a multi-tenant dwelling unit (MDU), a map of the MDU, where the map includes locations corresponding to multiple sensors at the MDU and defines multiple sub-areas of the MDU, receiving sensor data from one or more sensors of the plurality of sensors, where the sensor data is indicative of a fire event at the MDU, determining, from the sensor data, one or more sub-areas of the multiple sub-areas included in the fire event, generating, based on the sensor data, a targeted fire event response for the one or more sub-areas of the multiple sub-areas of the MDU, and providing, to the one or more sub-areas of the multiple sub-areas, the targeted fire event response.
