Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disaster safety lanterns lack functionality to effectively request rescue and provide comprehensive safety in disaster situations, such as earthquakes, fires, and gas leaks, especially during power failures when visibility is poor.
Innovation Solution
A multipurpose disaster safety lantern with integrated features like LED lights, a detection sensor for hazardous conditions, a motor for rotating the lantern, and a set with a fire extinguisher, which uses air discharge protrusions for attachment and automatic lighting to serve as a warning light, increasing visibility and aiding evacuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a simple lantern structure is used, then manufacturing cost and device complexity are reduced, but the ability to effectively request rescue and provide comprehensive safety in disaster situations is insufficient
Solution Approach 1:
The patent combines multiple disaster safety functions (lighting, rotation, hazard detection, warning) into a single integrated lantern device. The lantern merges the functions of a light source, motor-driven rotation mechanism, sensor system for detecting heat/gas/earthquakes, and warning light capabilities, allowing one device to perform comprehensive disaster safety tasks rather than requiring separate devices for each function
Solution Approach 2:
The lantern is designed as a multi-functional device that can serve multiple purposes in disaster situations: providing illumination through LED lights, rotating to increase visibility and request rescue, detecting hazardous conditions (heat, gas, earthquakes) via sensors, and emitting warning lights. This universal design allows a single lantern to adapt to various disaster scenarios including fires, gas leaks, and earthquakes
2Reliability
If additional functions (detection sensor, motor, multiple LEDs) are added to the lantern, then the ability to request rescue and ensure safety is improved, but device complexity increases
Solution Approach 1:
The patent integrates the detection sensor, motor, multiple LED bars, and control circuitry into a unified lantern system. The sensor detects hazardous conditions and automatically triggers the motor to rotate the lantern and activates the warning LEDs, merging detection, actuation, and warning functions into one coordinated system that improves reliability without requiring separate standalone devices
Solution Approach 2:
The lantern incorporates automatic response mechanisms where the detection sensor autonomously triggers the motor and warning lights when hazardous conditions are detected. The system self-activates the rotation and warning functions without requiring manual intervention, allowing the lantern to automatically request rescue and alert others of its location, thereby improving reliability through automated safety responses
3Illumination intensity
If the lantern remains stationary, then device complexity is minimized, but visibility and ability to notify location in hazardous situations is reduced
Solution Approach 1:
The patent introduces a motor-driven rotation mechanism that dynamically changes the lantern's orientation. Instead of remaining stationary, the lantern can rotate to actively display its warning lights and illuminate different areas, increasing its visibility and ability to notify others of its location. This dynamic capability transforms the lantern from a static light source to an active warning device that can attract attention from multiple directions
Solution Approach 2:
The motor rotates the lantern in periodic intervals, creating a rotating pattern of visible warning lights. This periodic rotation ensures that the lantern's illumination and warning signals are periodically displayed to observers from different angles, significantly enhancing its ability to notify location and request rescue compared to a stationary light source
