Removable Protective Battering Plate for Door Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forcible entry training devices for locked doors using battering rams often damage the doors due to repeated blows, as they are not adequately protected.
Innovation Solution
The use of protective battering plate devices, which are removably attached to the training apparatus, featuring a steel striking plate, u-shaped portion, beveled edge, and force limiting plate, to distribute impact forces and prevent damage to the door during simulated forcible entry training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeated blows are delivered to the door during forcible entry training, then the training effectiveness is improved, but the door structure is damaged
Solution Approach 1:
A removable protective plate is introduced as an intermediary component between the battering ram and the door. The plate absorbs the impact forces during training exercises, preventing direct damage to the door while maintaining realistic training conditions. The plate can be easily attached and removed without permanent modification to the door structure.
Solution Approach 2:
The protective plate is pre-installed on the door before training begins, providing cushioning protection in advance. This allows trainees to deliver repeated blows without worrying about damaging the door, as the protective plate is already in place to absorb and distribute the impact forces.
2Strength
If a protective plate is added to protect the door, then the door is protected from damage, but the device complexity increases
Solution Approach 1:
The protective system is segmented into a modular plate that can be independently attached and removed. This segmentation allows the protection function to be added without permanently modifying the door or training apparatus. The plate can be easily mounted using simple fasteners and removed when not needed, maintaining simplicity while providing protection.
3Strength
If a removable protective plate is used, then the door is protected during training, but the ease of operation is reduced due to additional attachment steps
Solution Approach 1:
The protective plate system transitions from a static permanent installation to a dynamic removable component. This allows the system to adapt between two states: protected during training and unprotected during normal door operation. The plate can be quickly attached and removed based on training needs, providing flexibility rather than permanent modification.
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
Enables effective simulation of forcible entry techniques while protecting the training apparatus from damage, allowing for repeated impacts without compromising the door's integrity.
Implementation Method 1
The protective battering plate device is configured to be impacted by a battering ram device to forcibly open the door of the forcible entry training door apparatus while protecting the door from damage
Data Source
AI summary
Protective battering plate devices are provided, which can be removably attached to a door of a forcible entry training door apparatus. A protective battering plate device is configured to enable simulated forcible entry of an inward swinging locked door by hitting a battering ram against the protective battering plate device mounted on the door of the forcible entry door training apparatus, while protecting the door from damage.
