Defense mobile device for shelter-in-place situations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door safety mechanisms and lockdown devices are costly, difficult to maneuver, and often fail to provide effective multi-layered protection against intruders, with many designs being unsuitable for inward-opening doors and lacking in user-friendliness, aesthetics, and functionality beyond defense.
Innovation Solution
A mobile defense device with a ballistic panel that can pivot and lock into place using a mechanical pivot and locking rod, featuring a base with wheels for easy maneuverability, a frame with grips for user handling, and a lever-locking mechanism for secure attachment to the door frame, also serving as a whiteboard or display unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If ballistic panels and partition systems are used to provide protection, then security protection is improved, but the device becomes difficult to maneuver and requires facility modifications
Solution Approach 1:
The device is divided into a mobile base unit with ballistic panels and a separate door integration component. The ballistic panels are segmented into movable sections that can be deployed independently, allowing the device to provide protection without requiring permanent facility modifications or difficult maneuvering of a single large structure.
Solution Approach 2:
The device combines multiple functions into a single unit: it serves as a ballistic barrier, a door reinforcement system, and a mobile security station. The base unit can be moved to different locations and adapted to various door types, eliminating the need for separate protection systems and facility modifications.
2Object-affected harmful factors
If existing lockdown devices are used to provide security, then protection is improved, but the devices are prohibitively expensive for facilities on a budget
Solution Approach 1:
The device uses cost-effective materials and modular components that can be manufactured at lower cost than traditional ballistic systems. The mobile base unit with integrated ballistic panels provides adequate protection for budget-conscious facilities without requiring expensive permanent installations or specialized materials.
Solution Approach 2:
The device replicates the protective function of expensive ballistic systems using more economical designs and materials. The ballistic panels are constructed to provide comparable protection to premium systems but at a fraction of the cost, making security accessible to facilities on a budget.
3Object-affected harmful factors
If existing lockdown devices are used, then some protection is provided, but they require diligent maintenance to avoid catastrophic failure
Solution Approach 1:
The device incorporates self-diagnostic and self-maintaining features that reduce reliance on diligent external maintenance. The mechanical pivot and locking rod system automatically adjusts and maintains itself, and the device provides visual or digital indicators of its operational status, allowing facilities to monitor reliability without constant professional inspection.
Solution Approach 2:
The device includes redundant components and fail-safe mechanisms that prevent catastrophic failure even if maintenance is neglected. The ballistic panels are designed with inherent structural resilience, and the locking mechanism incorporates backup systems that activate automatically if primary components fail, cushioning against the consequences of poor maintenance.

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 actuated, 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 lever-locking mechanism or a twist-lock mechanism secures the device in place against or within a door frame and against the door.
