Door Block Rod Entry Securing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard door locks are easily bypassed by intruders, providing insufficient time for authorities to respond to shooting events, as they can be forced open or unlocked through broken windows, leading to potential fatalities and injuries.
Innovation Solution
An entry securing apparatus comprising a rod secured to the door with supports, a door block with slots for the rod, and a fastener to secure the block in an engaged position, restricting door opening by overlapping with the door frame, thereby delaying intruder access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard door lock is used, then the door can be opened easily for normal access, but the door can be easily bypassed by an intruder applying force or breaking windows
Solution Approach 1:
The door blocking apparatus is divided into separate components: a door block, a rod with supports, and a fastener. This segmentation allows the system to provide robust security while maintaining ease of operation through simple assembly and disassembly actions.
Solution Approach 2:
The door block is pre-configured with slots and the rod is pre-positioned with supports before engagement. This preliminary preparation enables rapid deployment of the security mechanism without complex adjustments during the locking process.
2Reliability
If a rod and door block apparatus is added to enhance security, then resistance to intruder is improved, but device complexity increases
Solution Approach 1:
The door block is designed as a separate, removable component that can be taken out and stored when not in use. This extraction principle reduces the permanent structural complexity of the door system while maintaining security capabilities when needed.
Solution Approach 2:
The rod serves multiple functions: it connects the door block to the door frame, provides structural support, and enables the blocking mechanism. This multi-functionality reduces the number of separate components needed, simplifying the overall device complexity.
3Reliability
If the door block overlaps the door frame to restrict opening, then resistance to intruder is improved, but ease of operation decreases
Solution Approach 1:
The door block is designed to be dynamically positionable between engaged and disengaged states. This dynamic capability allows the system to switch between security mode (overlapping the frame) and operation mode (retracted), resolving the contradiction between security and ease of opening.
Solution Approach 2:
The rod acts as an intermediary mechanism that facilitates the movement and positioning of the door block. This mediator enables easy transition between locked and unlocked positions without requiring direct manual manipulation of the door block itself.

AI summary
An entry securing apparatus for securing a door is provided that may comprise a rod secured to the door with one or more supports; a door block comprising a slot for receiving the rod and allowing the rod to pass through the door block, the door block moveable from a disengaged position to an engaged position, wherein the door block is in the engaged position when a portion of the door block is overlapping at least a portion of a door frame surrounding the door; and a fastener for securing the door block in the engaged position, whereby opening of the door is restricted by the door block.
