Modular Vehicle Rescue Trainer with Telescoping Steering Column
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional training methods for vehicle rescue techniques are inadequate as they lack realism and do not effectively prepare first responders for the varied and complex scenarios encountered in real-world emergencies, particularly due to limitations in simulating vehicle orientations and obstructed access scenarios.
Innovation Solution
A modular training device with a framework that simulates a transportation device's interior, featuring adjustable components such as a telescoping steering column, pivotable foot pedals, and removable panels to mimic various emergency scenarios, allowing for realistic training in a classroom setting with a manikin or human occupant, and includes additional tools like a breaking-glass simulator and prying simulator for comprehensive training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an actual vehicle is used for training exercises, then the training scenario becomes more realistic with physical obstacles, but the vehicle cannot be repositioned to simulate different orientations and requires outdoor or garage environment
Solution Approach 1:
The training device is divided into a modular framework structure that can be assembled and disassembled. The framework includes separate components such as support members, platform members, and simulated vehicle interior elements that can be independently positioned and configured to create different training scenarios including various orientations.
Solution Approach 2:
The training device incorporates movable and adjustable components including the platform that can be tilted to simulate different vehicle orientations, and the telescoping steering column that can be adjusted to various positions. This dynamic design allows the same device to simulate multiple emergency scenarios without requiring physical repositioning of the entire structure.
2Reliability
If an actual vehicle is used for training, then trainees experience realistic physical obstacles, but the vehicle size obscures the view for onlookers and instructors
Solution Approach 1:
The device creates a simplified copy of the vehicle interior environment using a framework that replicates essential structural features such as the dashboard, steering column, and seating arrangements. This scaled-down model maintains training realism while eliminating the visibility problems associated with full-size vehicles, allowing instructors and observers to clearly view the training exercise from all angles.
3Ease of operation
If a chair simulation is used in classroom, then the training can be conducted indoors, but the scenario lacks physical obstacles and realism
Solution Approach 1:
The framework acts as an intermediary between the simplified chair simulation and the complex actual vehicle. It introduces essential physical obstacles such as the simulated dashboard, steering column, and footwell structure that replicate the confined space and structural barriers found in real vehicles, while still being compact enough for indoor classroom use.
4Device complexity
If the steering column is fixed position, then the device structure is simpler, but it cannot simulate collision scenarios where the steering column moves toward the occupant
Solution Approach 1:
The steering column is designed with telescopic capability, allowing it to be extended and retracted to simulate different collision scenarios. This dynamic feature enables the training device to replicate the movement of the steering column toward the occupant during impact events, providing realistic training for rescuers without requiring multiple static configurations.
Data Source
AI summary
Devices for simulating a transportation emergency are disclosed. The devices have a base with a framework of interconnected supports extending therefrom as a skeletal portion of a simulated transportation device and defining a chamber configured to receive a human or a medical-training manikin. Within the chamber a seat for receiving the human or the medical-training manikin is disposed. The framework defines one or more openings representative of access openings into the simulated transportation device such that a first responder in-training can receive instructions on how to assist a victim positioned in the simulated transportation device. The framework also defines one or more open frames representative of structural features of the simulated transportation device that block access to the victim such that realistic training occurs. The device may include one or more props such as a telescoping steering column, a prying simulator, a foot pedal unit, and a side impact bar.
