Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tools for breaching locked or reinforced doors, such as crowbars, battering rams, and explosives, are inadequate for providing sufficient force and angle to access secured entryways like SCIF doors, jail cell doors, and ship hatches, often causing hazards and failing to apply necessary torque effectively.
Innovation Solution
A double-sided breaching tool with a fixed and moving structure, utilizing hydraulic pressure to apply up to 10,000 pounds of force, featuring interchangeable blade sets designed for different types of doors and entryways, allowing for various angles and forces to be applied to breach doors with enhanced security features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional tools like crowbars or battering rams are used to breach doors, then some force can be applied to the door structure, but they cannot provide sufficient angle and force application to heavily locked or reinforced doors
Solution Approach 1:
The breaching device features a nested structure where an inner breaching structure is contained within an outer breaching structure. The inner structure includes components that can be inserted into narrow door gaps, while the outer structure provides additional force application surfaces and leverage points, allowing the device to adapt to various door configurations and provide sufficient force at multiple locations simultaneously.
Solution Approach 2:
The device transitions from conventional single-point force application to multi-dimensional force distribution by engaging the door structure at multiple points and angles simultaneously. The dual-structure design allows force to be applied both directly to the door and at angled positions, creating a comprehensive breaching approach that overcomes reinforced locking mechanisms.
2Reliability
If advanced door security features like tighter door gap spaces are used, then door security is improved, but tools requiring insertion into door gaps cannot be effectively applied
Solution Approach 1:
The breaching device is segmented into distinct functional components: an outer breaching structure with its own force application surfaces, an inner breaching structure that can be inserted into narrow gaps, and a hydraulic system that coordinates their movement. This segmentation allows each component to perform its specific function while working together to breach doors with various security features.
Solution Approach 2:
The device incorporates dynamic movement where the inner breaching structure can move relative to the outer structure. The hydraulic system enables the inner structure to be advanced into narrow door gaps while the outer structure remains positioned for additional force application, allowing the device to adapt its configuration based on the specific door geometry and security features encountered.
3Ease of operation
If hinge rupturing tools are used to gain entry to locked or reinforced doors, then some access can be obtained, but they do not provide sufficient force or effectiveness
Solution Approach 1:
The device merges multiple force application mechanisms into a single integrated system. The outer and inner breaching structures work together, with the hydraulic system combining their forces and coordinating their movement to apply concentrated force to the hinge area. This merging of functions provides the sufficient force needed to rupture hinges on reinforced doors while maintaining operational ease.
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 device effectively breaches locked or reinforced doors and entryways by providing sufficient force and torque, capable of accessing deeply recessed hinges and locks, even in narrow gaps, with minimal setup time and versatility for different types of security doors and entry structures.
Implementation Method 1
The device utilizes a fixed breaching structure and a moving breaching structure separated by a space. The moving breaching structure is moved away from the fixed breaching structure to create a separating force between the door and door frame.

AI summary
The present invention relates to a breaching device which may be used to gain access to a door, window, or other structure. More specifically, the present invention is a breaching device including a fixed breaching structure and a moving breaching structure to provide torque and angle forces on the structure to be breached. The fixed breaching structure includes a first fixed blade set arranged to remain in a fixed position while a first moving blade of the moving breaching structure is actuated to open a first gap. Then, if necessary, a second fixed blade set and a second moving blade of the device are used to complete the separation of the door from its frame. The second blade set may be used to complete the breach of the structure or may be designed as a multi-purpose tool to use on a different structure. The first fixed blades are relatively shorter than the second fixed blades. The first moving blade is shorter than the second moving blade.
