Television Receiver Evacuation Route Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home automation systems lack effective methods to quickly and safely guide occupants to emergency exits during fires, particularly in determining evacuation routes based on fire location and occupant positions, and integrating with lighting and locking systems for clear navigation.
Innovation Solution
A method and system utilizing a television receiver to detect fire signals, assess evacuation risks, and map emergency exit paths by controlling lighting and door locks to indicate safe routes, while also considering fire size, occupant traits, and fire protection device status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If home automation systems integrate fire detection and evacuation route mapping, then safety and evacuation effectiveness are improved, but device complexity increases
Solution Approach 1:
The television receiver is designed to perform multiple functions: it serves as both an entertainment device and an emergency response system that detects fire signals, assesses evacuation risks, maps emergency exit paths, and controls lighting devices. This multi-functionality integrates fire detection, risk assessment, route mapping, and navigation guidance into a single existing device, improving evacuation safety without requiring multiple separate systems
Solution Approach 2:
The patent combines fire detection functionality, risk assessment algorithms, emergency route mapping capabilities, and lighting device control into an integrated system hosted on the television receiver. This merging of previously separate functions into a unified system reduces the number of independent components needed while maintaining comprehensive emergency response capabilities
2Measurement precision
If the system maps emergency exit paths based on fire location and occupant positions, then evacuation effectiveness is improved, but measurement and detection difficulty increases
Solution Approach 1:
The system employs sensors distributed throughout the building as intermediary devices that detect fire location and occupant positions. These sensors act as mediators between the physical environment (fire and occupants) and the television receiver's processing system, converting physical conditions into detectable signals that enable precise location mapping without requiring the main device to directly sense all parameters
Solution Approach 2:
The system continuously receives feedback from sensors regarding fire location, occupant positions, and environmental conditions. This real-time feedback enables dynamic updates to the emergency exit path mapping, allowing the system to adjust routes based on changing conditions while maintaining accurate location tracking throughout the evacuation process
3Illumination intensity
If lighting devices are controlled to indicate emergency exit paths, then navigation clarity is improved, but energy consumption increases
Solution Approach 1:
The lighting devices are controlled to operate periodically or intermittently rather than continuously during the emergency situation. The system can flash lights, alternate between different lighting patterns, or activate only specific segments of the path as needed, providing sufficient visual guidance for evacuation while reducing overall energy consumption compared to continuous full-path illumination
Solution Approach 2:
The system activates lighting devices locally only in the areas needed for the current evacuation route rather than illuminating the entire building uniformly. By concentrating lighting resources on the specific exit path relevant to occupants' locations and the fire position, the system achieves adequate path visibility while minimizing unnecessary energy consumption in unoccupied or already-safe areas

AI summary
Systems and methods for indicating an emergency exit path upon detection of a fire in a building structure. The systems and methods may include detecting a signal indicating presence of the fire in the building structure and determining an evacuation situation is present based on a risk assessment. In response to determining the evacuation situation is present, the systems and methods may include mapping the emergency exit path out of the building structure based on an identified location of the fire and an identified location of a person in the building structure, and operating a plurality of lighting devices in the building structure to indicate the emergency exit path out of the building structure.
