Solution Overview

Problem

Conventional training doors for simulating door-breaking scenarios in shoot houses are expensive, prone to destruction, and limited in reusable and versatile options, failing to provide a realistic and cost-effective solution for repeated use and varied entry methods.

Innovation Solution

A modular training door constructed with bullet-proof steel and destructible materials, allowing for various entry methods and easy replacement of parts, featuring innovative hinge and latch mechanisms that can be customized for different training scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional door is used in training scenarios, then the door can be broken open using various entry methods, but the door is destroyed during each exercise requiring expensive replacement

Engineering Contradiction:

Improvedoor entry methodsVSAvoiddoor reusability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The training door is divided into a permanent frame structure and replaceable door panels. The frame remains intact while different panels can be attached and removed, allowing the door to be reset after each training exercise without replacing the entire door assembly.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements a system where only the door panel (not the entire door) is replaced after destruction. The frame, hinges, and mounting mechanisms are recovered and reused, while only the damaged panel is discarded and replaced with a fresh one.

Inventive Principle:

Principle #34Discarding and recovering

2Reliability

If a reusable training door is constructed to withstand breaking, then the door can be used multiple times, but it cannot be opened by various entry methods without destroying it

Engineering Contradiction:

Improvedoor reusabilityVSAvoidentry method variety

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

Different portions of the door panel have different properties - some areas are designed to be more vulnerable to specific entry methods (e.g., weaker panels for kicking, specific weak points for shotguns or explosives) while the overall structure remains durable enough to withstand repeated use.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If multiple doors are installed in a training building, then various training scenarios can be simulated, but considerable time and expense are required to replace all doors between sessions

Engineering Contradiction:

Improvetraining scenario varietyVSAvoiddoor replacement time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The door system is segmented into permanent frames and replaceable panels, allowing quick panel swaps instead of complete door replacements. This reduces the time required to reset multiple training doors between sessions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple door panels can be prepared in advance with different configurations or conditions, allowing trainers to quickly swap panels to set up different training scenarios without extensive on-site preparation.

Inventive Principle:

Principle #10Preliminary action

AI summary

A reusable ballistic door for use in the training of individuals such as police officers and military personnel. The door may be formed to have different weak spots, requiring different techniques to enter the door. The door may be quickly and inexpensively rebuilt for subsequent training. A reusable training door may also be used inside of a shoot house to provide realistic training scenarios.
