Wireless Smoke Alarm Flashlight Merging Detection and Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smoke alarm systems often fail to effectively warn occupants of smoke or fire, particularly in darkened areas, leading to higher mortality rates and property damage, as they lack integrated solutions for providing light and clear warnings in emergency situations.
Innovation Solution
A smoke alarm system with wireless-signal-send-and-receive functionalities, including a hand-held flashlight with wireless-signal-receiving capability, that projects light, emits an alarm sound, and vibrates upon receiving a smoke-or-fire-triggered signal, optionally incorporating a remote control for testing and programming, and transmitting data to offsite devices for enhanced safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional smoke alarm systems are used, then fire detection is provided, but effective warning and evacuation assistance in darkened areas is not provided
Solution Approach 1:
The patent combines a smoke alarm system with a flashlight system into an integrated emergency warning device. The smoke detector, flashlight, sound alarm, and vibrator are merged into a single unit that responds to smoke detection by activating all warning functions simultaneously, providing both light and auditory/tactile alerts to assist occupants in evacuation.
Solution Approach 2:
The emergency warning system is designed to perform multiple functions: smoke detection, light projection, sound alarm, and vibration warning. This multi-functional device adapts to different emergency scenarios, including situations where occupants may be deaf, blind, or in completely darkened areas, making the system universally applicable to various disability and environmental conditions.
2Reliability
If smoke alarm systems lack integrated light and sound warning, then device complexity is reduced, but occupant safety and evacuation effectiveness deteriorate
Solution Approach 1:
The patent merges multiple warning mechanisms (flashlight, sound alarm, vibrator) with the smoke detector into a single integrated unit. The control circuit receives smoke detection signals and simultaneously activates all warning components, providing coordinated light, sound, and tactile alerts that enhance occupant safety without requiring separate systems.
Solution Approach 2:
The emergency warning system is designed to activate automatically upon smoke detection without requiring manual intervention. The control circuit self-manages the coordination of all warning components (light, sound, vibration), and the system includes self-testing capabilities that allow users to verify functionality without technical expertise, making the complex system user-friendly.
3Ease of operation
If wireless signal transmission is added to activate flashlight and alarm, then remote warning capability is improved, but device complexity and energy consumption increase
Solution Approach 1:
The wireless communication system is designed to transmit signals periodically or on-demand rather than continuously. The control circuit activates the wireless transmitter only when smoke is detected or when testing is initiated, allowing the system to conserve energy during normal operation while maintaining remote activation and testing capabilities when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system significantly enhances occupant safety by providing a reliable light source and warning mechanism during emergencies, potentially saving lives and reducing property damage by ensuring timely evacuation and alerting authorities to fire situations.
Implementation Method 1
a smoke detector, in the home or other building, comprising a computing system supporting at least wireless-signal-sending functionality
Implementation Method 2
the flashlight's main light source projects light (typically in a high intensity beam)
Implementation Method 3
the flashlight's sound alarm emits a loud intermittent or continuous warning tone
Implementation Method 4
a vibrator in the hand-held flashlight vibrates the flashlight when the hand-held flashlight receives an activating wireless signal
Implementation Method 5
a signal transmission component that transmits data on smoke or fire status to an offsite device
