Fire Extinguisher Training Device Using Mobile AR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire extinguisher training simulators are limited by the need for users to face a fixed display screen and do not realistically simulate the mechanism of a fire extinguisher, such as the pull pin and trigger, leading to a lack of realism in training.
Innovation Solution
A fire extinguisher training device with a twin-handle trigger mechanism, a trigger sensor, and an electronic control module that communicates with a display device to simulate the discharge of a fire-suppressing substance, incorporating augmented reality to provide a realistic training experience, including the simulation of the pull pin and trigger mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a fixed display screen is used to show simulated flames, then the display can dynamically show flame attenuation and extinguishment, but the user must always face the screen which reduces realism and mobility
Solution Approach 1:
The patent transitions from a fixed 2D display screen to a mobile device with camera and display that can be positioned in multiple orientations and distances. The camera captures the real flame from any angle, and the display shows the simulated effect, allowing users to move freely while maintaining the training simulation.
2Measurement precision
If conventional sensors and fixed screens are used, then flame orientation can be detected, but other aspects of the extinguisher mechanism such as pull pin and trigger cannot be simulated
Solution Approach 1:
The mobile device serves multiple functions: it acts as the display screen, the orientation sensor, and the trigger mechanism interface. The camera captures flame orientation, the touchscreen detects trigger activation, and the processed image displays the simulated effect, consolidating multiple simulation functions into a single universal device.
3Reliability
If a replica fire extinguisher with fixed screen is used, then the basic extinguishing action can be simulated, but the training lacks realism and interactivity
Solution Approach 1:
The mobile device acts as an intermediary between the user and the training simulation. Instead of a complex fixed system with multiple sensors and displays, the smartphone or tablet serves as the mediator that captures real-world flame data through its camera and processes it to create the simulated extinguishing effect on its display.
