Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door safety mechanisms and lockdown devices are costly, difficult to maneuver, often cause bullet ricochets, and lack versatility in accommodating various door types and sizes, failing to provide effective multi-layered protection against intruders in emergency situations.
Innovation Solution
A defense mobile device with a ballistic panel that can pivot and lock into place, featuring a mechanical pivot system, locking rod, and lever-locking mechanism, designed to be user-friendly, affordable, and adaptable to both inward and outward-opening doors, incorporating a ballistic core to prevent ricochets and provide additional protection layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing door safety mechanisms and lockdown devices are used, then protection against intruders is provided, but they are costly and difficult to maneuver
Solution Approach 1:
The defense mobile device is divided into separable components including a panel with ballistic core, base with wheels, and locking mechanism. This segmentation allows the device to be maneuvered in sections and assembled at the destination, reducing the difficulty of operation while maintaining protective reliability
Solution Approach 2:
The patent introduces a release system with cable and pulley mechanism as an intermediary between the locking rod and the panel. This intermediary system enables easy deployment and retrieval of the protective panel by allowing operators to manipulate the locking mechanism from a safe distance, improving ease of operation without compromising protection
2Reliability
If existing lockdown devices are used, then door protection is provided, but they cause bullet ricochets
Solution Approach 1:
The panel incorporates a ballistic core with composite material construction designed to stop bullets without causing ricochets. The composite structure absorbs and dissipates bullet energy through controlled deformation and fragmentation, preventing the harmful ricochet effect while maintaining door protection capability
Solution Approach 2:
The patent converts the harmful effect of bullet impact into a beneficial stopping mechanism. The ballistic core is designed to transform the kinetic energy of incoming bullets into controlled material deformation and heat, converting the harmful ricochet potential into a safe energy dissipation process that stops threats effectively
3Reliability
If existing security devices are used, then some protection is provided, but they lack versatility in accommodating various door types and sizes
Solution Approach 1:
The defense mobile device incorporates a mechanical pivot system that allows the panel to dynamically adjust its position and angle. This dynamic capability enables the same device to accommodate various door types and sizes by adapting the panel orientation, maintaining protection reliability across different installation scenarios
Solution Approach 2:
The patent designs the panel and base assembly as a universal system that can be deployed with different door configurations. The adjustable positioning mechanisms and adaptable locking system enable a single device design to serve multiple door types and sizes, enhancing versatility without sacrificing protective reliability
4Reliability
If existing lockdown devices are used, then door securing is provided, but extensive structural modifications are required
Solution Approach 1:
The defense mobile device is designed as a self-contained system that brings its own mounting and securing mechanisms. The base with wheels and locking system enables the device to install and secure itself to the door structure without requiring extensive pre-installed infrastructure, reducing manufacturing complexity and installation requirements while maintaining door securing reliability

AI summary
A defense mobile device for securing a door during shelter-in-place situations. The device includes wheels rendering it mobile and stops that, when activated, hold the device stationary. A panel has a ballistic core that resists bullets, a front face, an opening, and a cover positioned over the opening to overlay and enclose a door knob protruding through the opening. The front face forms, or has affixed to it, a writing surface. The panel pivots between a plurality of angled positions to facilitate writing and an upright position flat against the door. A locking rod, rotatably connected to the panel, pushes and pulls the panel between its angled positions and its upright position. A portal defined by a ballistic door viewer or viewport is located in the panel and permits viewing or observing through the panel. A release system is configured to deactivate the stop and enable the device to move.
