Smartlock Fire Routing With Temperature-Based Door Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire safety systems lack the ability to automatically and efficiently direct occupants to safe routes during emergencies, such as fires, while ensuring doors are unlocked or locked as needed to facilitate evacuation.
Innovation Solution
A smartlock device integrated with temperature sensors and a radio device that communicates with a monitoring system to unlock doors based on temperature readings and sensor data, providing real-time status indications and routing directions to occupants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fire safety systems use traditional manual door control during emergencies, then occupants can maintain control over door access, but evacuation efficiency is reduced and response time is delayed
Solution Approach 1:
The system pre-identifies safe evacuation routes and pre-configures door control logic before emergencies occur. When fire is detected, the system immediately executes pre-planned door unlocking sequences for identified safe routes, eliminating the need for real-time decision-making during evacuation
Solution Approach 2:
The system continuously monitors temperature sensors and fire detection devices to receive real-time feedback about fire location and spread. Based on this feedback, the system dynamically adjusts which doors remain locked and which are unlocked to guide occupants along safe evacuation paths
2Speed
If doors are automatically unlocked during fire emergencies, then evacuation speed is improved, but security control is reduced
Solution Approach 1:
The system applies different door control policies to different locations based on fire position. Doors along safe evacuation routes are unlocked to enable rapid egress, while doors leading toward or near the fire remain locked to prevent occupants from entering dangerous areas. Each door's lock status is independently controlled based on its specific location relative to the fire
Solution Approach 2:
The smartlock device acts as an intermediary between security requirements and evacuation needs. It receives commands from the fire safety system and executes precise door control actions, mediating between the conflicting demands of maintaining security control and enabling rapid evacuation by selectively controlling access to different areas
3Adaptability or versatility
If smartlock devices integrate temperature sensors and communication modules, then fire detection and routing capability is improved, but device complexity increases
Solution Approach 1:
The smartlock device is designed to perform multiple functions: normal door locking/unlocking, fire detection via temperature sensors, emergency evacuation routing, and communication with the fire safety system. By integrating these diverse functions into a single device, the system avoids the need for separate dedicated devices for each function, thereby managing complexity while enhancing adaptability

Function Achieved in This Case
Enhances fire safety by automatically unlocking doors to safe routes, minimizing injury risk and aiding evacuation, while also providing real-time alerts and guidance to occupants and emergency responders.
Implementation Method 1
a sensor that is operable to determine a first temperature of the smartlock device or a second temperature of a room that is accessible via the door
Data Source
AI summary
Methods, systems, and apparatus, including computer programs encoded on computer storage mediums, for a smartlock device that can be integrated in a door at a property. The smartlock device includes a locking mechanism configured to lock the door and to unlock the door. The device includes a radio device and a sensor that determines a first temperature of the smartlock device and a second temperature of a room that is accessible via the door. The radio device is operable to: i) receive parameter signals from the sensor indicating each of the first and second temperatures; ii) transmit data that includes the first and second temperatures to a monitoring system; and iii) receive a command to cause the locking mechanism to unlock the door based on information from the monitoring system. The information includes a determined routing of occupants at the property and is presented on a display of the device.
