VR Fire Simulator Base Motion and Safety Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality fire-fighting training methods lack immersion and realism, relying on game-oriented systems that fail to replicate the physical sensations of actual fire scenarios, resulting in ineffective experiential learning.
Innovation Solution
A fire-fighting virtual reality simulator that includes a base motion unit for tilting and vertical movement, a safety support system with a bellows-type safety wire, and sensors to track trainee movement and posture, providing a realistic fire-fighting experience by simulating floor movements and allowing free motion without physical restraint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a treadmill simulator with waist belt restraint is used, then trainee safety is ensured, but freedom of motion and postural support are restricted
Solution Approach 1:
The patent employs a counterweight mechanism that balances the trainee's body weight, allowing free motion without physical restraint. The counterweight system compensates for the trainee's weight, enabling natural movement and postural changes while maintaining safety, thus resolving the contradiction between safety and freedom of motion.
Solution Approach 2:
The patent introduces an intermediary safety system that monitors and supports the trainee without direct physical restraint. This intermediary mechanism provides safety assurance while allowing unrestricted movement, bridging the gap between safety requirements and freedom of motion needs.
2Ease of operation
If game-oriented virtual reality systems are used, then accessibility and ease of operation are improved, but sense of presence and immersion are reduced
Solution Approach 1:
The patent segments the virtual reality system into multiple functional components: a motion platform for physical sensation, a head-mounted display for visual immersion, and an audio system for spatial sound. This segmentation allows each component to specialize in providing specific immersive experiences while maintaining overall system accessibility.
Solution Approach 2:
The patent utilizes pneumatic or hydraulic mechanisms to generate realistic floor movements, vibrations, and tilts that simulate actual fire-fighting environments. These mechanical systems provide authentic physical feedback that enhances presence and immersion while maintaining ease of operation through automated control.
3Reliability
If physical restraint devices are used, then trainee safety is improved, but realism of fire-fighting training is reduced
Solution Approach 1:
The patent replaces traditional mechanical restraint systems with a sophisticated control and monitoring system that uses sensors, actuators, and software algorithms to ensure safety. This substitution eliminates physical restraints that compromise realism while maintaining safety through intelligent control mechanisms.
Solution Approach 2:
The patent dynamically adjusts various parameters such as motion intensity, environmental conditions, and safety thresholds based on real-time trainee performance and physiological data. This parameter adjustment allows the system to maintain safety while progressively increasing training realism as the trainee becomes more comfortable and capable.

AI summary
A fire-fighting virtual reality simulator allows the trainee to move in a virtual space in various complex virtual fire disaster situations and perform a suppression of a virtual fire and a confrontation training. An experience interactive simulator for providing a trainee with a floor movement that may occur in a fire disaster situation so that the trainee wearing HMD in a virtual fire-fighting training has the same sense of feeling as that in an actual fire-fighting training is provided. For the realistic content experience, a physical floor movement, such as tilting, falling, and shaking of the floor is reproduced using a base motion, thereby providing a floor movement that enables a sense of feeling similar to a fire disaster situation.
