Hazard Suppression Simulator Using 3D Props and Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fire training simulators provide only a two-dimensional training experience, failing to offer a truly immersive and realistic simulation of hazardous conditions, which limits the effectiveness of training for personnel in suppressing fires and other hazardous situations.
Innovation Solution
The development of hazard suppression training simulators that incorporate three-dimensional props, light sources, smoke, sound effects, and sensors to create a realistic hazardous environment, allowing for the detection and response to simulated or actual hazard suppressants, thereby enhancing the training experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two-dimensional training systems are used, then device complexity is reduced, but training realism and immersion are insufficient
Solution Approach 1:
The patent transitions from two-dimensional flat displays to three-dimensional virtual reality environments. The system uses stereoscopic displays, spatial audio, and volumetric smoke effects to create immersive 3D hazardous condition simulations, allowing trainees to experience realistic fire and hazard scenarios without proportionally increasing system complexity through modular component integration.
2Reliability
If live fire training is used, then training realism is improved, but trainee safety risks increase
Solution Approach 1:
The patent introduces virtual reality as an intermediary between trainees and actual hazardous conditions. The system uses virtual fire simulations with light sources, smoke generators, and sensor-detected suppressant interactions to create realistic training scenarios without exposing trainees to genuine fire dangers, thereby maintaining training effectiveness while eliminating safety risks.
Solution Approach 2:
The patent creates accurate copies of hazardous conditions through virtual reality simulations. The system replicates fire behavior, smoke propagation, and suppressant interactions using sensors and visual effects, providing trainees with authentic training experiences that mirror real-world scenarios without the inherent dangers of actual live fire training.
3Reliability
If three-dimensional training props with multiple sensors and effects are used, then training realism is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-functional components that serve multiple purposes simultaneously. The virtual reality system integrates visual displays, audio output, smoke generation, and sensor detection into unified modules. For example, the same virtual environment renders both visual fire effects and spatial audio cues, while sensor arrays detect both suppressant presence and trainee interactions, reducing overall system complexity through functional consolidation.
Data Source
AI summary
A hazard-suppression training simulator for training, for example, first responders, is provided. The simulator includes a housing; at least one source of sensation (for example, a visual or an audio sensation) representing a hazardous condition, for example, a fire; at least one sensor adapted to detect a simulated or an actual hazardous condition suppressant; and a controller adapted to vary the sensation in response to the simulated or the actual suppressant detected by the at least one sensor. The simulator may also include one or more “props” to better simulate an actual hazardous conditions, for example, a trash can or a stove pot that is on fire. The simulated suppressant may be provided by a simulated fire extinguisher, for example, a simulated extinguisher emitting an electromagnetic or sonic signal representing a fire suppressant. A hazard-suppression training method employing this simulator is also disclosed.
