Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current simulators fail to realistically replicate the unpredictable and dangerous conditions of confined and polluted environments, leading to inadequate training for rescue personnel, who may face unexpected structural failures and hazards during operations.
Innovation Solution
A portable simulator with movable partitions and adjustable passage openings, equipped with interactive systems to recreate critical situations like falls, toxic gases, and structural failures, allowing for training in variable geometry environments and the simulation of emergency procedures like Lock Out Tag Out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed-configuration simulators are used for training, then the training environment is stable and easy to manage, but the simulator cannot realistically replicate unpredictable structural failures and hazardous conditions of confined environments
Solution Approach 1:
The patent applies the dynamics principle by implementing movable partitions (17, 18) that can slide on rails within the simulator container. These partitions allow the internal configuration to change dynamically during training exercises, enabling the simulation of structural failures, collapsing walls, and unexpected environmental changes that occur in real confined space incidents, thereby resolving the contradiction between stability and variability
Solution Approach 2:
The simulator is segmented into multiple compartments separated by movable partitions that can be independently positioned. This segmentation allows different zones to represent different hazard conditions (toxic gas areas, structural failure zones, confined spaces) that can be activated independently, enabling realistic replication of unpredictable environmental conditions while maintaining overall system manageability
2Adaptability or versatility
If movable partitions and adjustable openings are added to create variable geometry environments, then the simulator can realistically reproduce critical situations, but the device complexity increases
Solution Approach 1:
An operator in a control cabin (16) serves as an intermediary who manages the complexity of movable partitions and adjustable openings. The operator controls these elements remotely to create realistic hazard scenarios without requiring trainees to directly manage the complex mechanisms, thereby enabling environmental variability while keeping the system manageable through centralized control
Solution Approach 2:
The patent replaces complex manual mechanical adjustment systems with motorized or automated control mechanisms for the movable partitions and adjustable openings. This substitution reduces the physical complexity and manual intervention required while maintaining the ability to create variable geometry environments and reproduce critical situations realistically
3Reliability
If the simulator includes features to simulate falls, toxic gases, and structural failures, then the training realism is improved, but the safety risks during training operations increase
Solution Approach 1:
The simulator converts potentially harmful elements (toxic gases, structural failures, falls) into controlled training benefits by using safe simulants and controlled environments. For example, toxic gases are simulated using harmless substances that mimic their effects, and structural failures are replicated using controlled partition movements rather than actual dangerous collapses, thereby maintaining training realism while eliminating actual safety risks
Solution Approach 2:
The simulator implements beforehand cushioning by providing controlled safety mechanisms and emergency protocols before training scenarios begin. The operator can pre-position safety barriers, control the release of simulants, and establish emergency procedures to cushion any unexpected events during training, ensuring that even when critical situations are simulated, actual harm is prevented

AI summary
A simulator for training in confined and / or suspected pollution environments consists of a container (1) having a base (2), a roof (3) opposite the base (2), and short perimeter walls (5, 6) and long (7, 8) with at least one vertical manhole (10), a horizontal manhole (12) and two safety exits (21, 22) to the outside. The two long perimeter walls (7, 8) delimit a plurality of internal compartments (13, 14, 15) for the exercise of the personnel with equipment that create effects for the training activity, and at least one training activity control, command and management cabin (16) with operator present. The internal compartments (13, 14, 15) for the personnel training are at least partially separated by means of movable walls (17, 18) disposed transversely to the two long perimetral walls (7, 8). The movable walls (17, 18) have adjustable passage openings through sliding partitions (19, 20).
