Reusable Breaching Training Door With Floating Jamb Force Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing training apparatuses for breaching doors are not robust enough to withstand the forces exerted by breaching tools and do not simulate realistic scenarios, leading to inefficiencies and potential damage during training.
Innovation Solution
A training apparatus comprising a door and door frame with a floating jamb that allows sideways movement, supported by the frame but not fixed directly, and equipped with spring mechanisms and replaceable sleeves to simulate various locking scenarios and resist compression forces, along with additional training assemblies for different breaching techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the door jamb is fixed directly to the door frame, then the structural stability is improved, but the ability to simulate realistic breaching scenarios and absorb forces is worsened
Solution Approach 1:
The door jamb is designed to be movable rather than fixed, allowing it to dynamically respond to breaching forces. The jamb can move sideways within confined spaces and is biased by springs to return to position, enabling realistic simulation of door frame behavior during breaching operations while maintaining structural integrity through controlled movement.
2Strength
If robust materials are used throughout the assembly, then the strength to withstand breaching forces is improved, but the cost and weight are worsened
Solution Approach 1:
Robust steel profiles are used specifically in critical load-bearing areas such as the door frame and door structure, while lighter materials or simplified designs are used in non-critical areas. This localized application of strong materials provides necessary strength to withstand breaching forces while minimizing overall weight and cost.
3Adaptability or versatility
If the door jamb is made movable to simulate realistic scenarios, then the training effectiveness is improved, but the device complexity is worsened
Solution Approach 1:
The door jamb is segmented into movable and fixed portions, with the movable jamb supported by springs and guided within confined spaces. This segmentation allows the jamb to move independently to simulate realistic breaching scenarios while the fixed frame provides stable support, managing complexity through functional division.
4Ease of repair
If replaceable components are used, then the ease of repair and maintenance is improved, but the initial device complexity is worsened
Solution Approach 1:
Replaceable components such as the door jamb, sleeves, and springs are designed as separate, extractable modules that can be easily removed and replaced. This extraction of critical wear components allows for simple maintenance and repair operations while the modular design actually simplifies the overall system architecture compared to integrated designs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus provides a robust and realistic training environment that minimizes damage while allowing for varied difficulty levels and simulates multiple breaching scenarios, enhancing the efficiency and effectiveness of training for first responders and military personnel.
Implementation Method 1
The two jambs are mounted on a base and connected at the top by a horizontal member. The distinguishing feature of this apparatus is that the door hinges are mounted to the hinge jamb in a manner that allows sliding motion toward and away from an inner surface of the hinge jamb, and the hinges include springs that bias the sliding hinges away from the hinge jamb and which resist compression with sufficient force to simulate forces that are encountered when attempting to wedge a pry tool between the door and the door stop jamb.

AI summary
Presented herein is a training apparatus designed for training first responders, law enforcement and military personal in the use of breaching tools. The training apparatus comprises: a door and a door frame. The door frame comprises an additional upright profile that functions as the door jamb located between a lock side upright of the door frame and a lock side rail of the door. The door jamb is supported by the door frame but not fixed directly to it at either the top or the bottom of the door jamb, thereby allowing the door jamb to move away from a lock side rail of the door during a breaching exercise. Also described herein are several add-on training assemblies that provide different realistic training scenarios.
