Door Barricade Locking Arm Floor Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door barricade solutions are ineffective in preventing intruders from entering rooms, as they can be easily kicked in or tampered with, and often require external access to locking mechanisms, which poses a risk to occupants during emergencies.
Innovation Solution
A door barricade system that mounts between the interior door face and the adjacent floor, featuring a rotating vertical bolt, locking arm, and wireless electronic device, allowing for secure engagement without external tools and enabling immediate activation without opening the door, even on doors without handles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a door barricade uses a removable pin, key, or similar component for locking, then the device can be easily installed and removed, but the removable component can be lost or stolen, rendering the device useless in an emergency
Solution Approach 1:
The patent removes the removable pin or key component entirely from the system. Instead, the locking mechanism uses a permanent integral locking bar that is fixed to the door and engages with a receiver in the frame, eliminating the risk of loss or theft while maintaining ease of operation through a simple thumb-turn actuator.
Solution Approach 2:
The locking mechanism is designed to be self-contained with no external components needed for operation. The thumb-turn actuator directly drives the locking bar into or out of engagement with the receiver, making the system self-sufficient and eliminating dependency on removable keys or pins that could be lost.
2Strength
If a door barricade attaches to the door jamb, then the device can provide structural support, but the door can still be easily kicked in and break the door jamb
Solution Approach 1:
The patent divides the barricade system into two separate components: a locking bar attached to the door and a receiver attached to the frame. This segmentation distributes the structural load and prevents concentrated stress on the door jamb, making forced entry more difficult while maintaining strong structural support.
Solution Approach 2:
Instead of relying solely on vertical attachment to the door jamb, the patent introduces a horizontal dimension by extending the locking bar laterally to engage with the receiver in the frame. This creates a multi-dimensional structural system that resists forced entry from multiple directions.
3Ease of operation
If a door lock requires going outside the classroom into the hallway to utilize, then the locking mechanism can be simple and accessible, but it exposes occupants to the line of danger during an intruder situation
Solution Approach 1:
The patent introduces a thumb-turn actuator as an intermediary component that allows occupants to operate the locking mechanism from inside the room through the door panel. This mediator transmits the locking action remotely, eliminating the need to exit the safe zone while maintaining simple and accessible operation.
Solution Approach 2:
The locking mechanism is designed to be engaged in advance before an emergency situation develops. The thumb-turn actuator allows quick preliminary locking of the door from inside the room, establishing safety before any threat materializes, rather than requiring reaction after danger is present.
4Reliability
If a door barricade uses a complex locking mechanism with multiple components, then the device can provide enhanced security, but the device complexity increases and may require specialized tools for operation
Solution Approach 1:
The patent merges multiple functions into a single integrated locking bar component that provides both structural support and locking engagement. The locking bar combines the functions of a strut, a latch, and a structural brace, reducing the total number of components while maintaining enhanced security against forced entry.
