Barrier Locking System with Slidable Rod and Cam Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current barrier locking systems fail to provide a safe and accessible environment during emergencies, as they often require complex setups, lack quick access for emergency responders, and do not meet National Fire Protection Association Life Safety Code requirements, posing risks to individuals in schools, offices, and other buildings.
Innovation Solution
A barrier locking system featuring a slidable lock rod with grooves, a pivot lever, and a cam member that can be rotated or linearly moved to disengage the lock, allowing authorized access while maintaining security, including a coil spring for vertical movement and a control box for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a barrier locking system is installed to restrict unauthorized entry, then security is improved, but emergency access and egress capability deteriorates
Solution Approach 1:
The patent introduces an intermediary release mechanism (button, cam member, or wire) that mediates between the locked state (providing security) and the unlocked state (providing emergency access). This intermediary allows authorized personnel to easily disengage the lock rod from the floor insert when needed, resolving the contradiction between maintaining security and enabling emergency access.
Solution Approach 2:
The patent inverts the traditional locking approach by making the locked state the default secure state that can be easily released, rather than requiring complex unlocking procedures. The lock rod is spring-loaded to automatically engage with the floor insert, and reversal of the handle or activation of the release mechanism quickly disengages it, allowing emergency personnel to gain immediate access when needed.
2Reliability
If a complex barrier locking system is used to enhance security, then security is improved, but device complexity increases
Solution Approach 1:
The patent segments the locking system into distinct functional components: a lock rod with engagement features, a floor insert with corresponding receptacles, a spring mechanism for automatic engagement, and a simple release mechanism. This segmentation allows each component to perform its specific function efficiently while keeping the overall system relatively simple and easy to understand.
Solution Approach 2:
The spring-loaded lock rod automatically engages with the floor insert without requiring manual intervention, providing self-service locking functionality. This eliminates the need for complex locking procedures or multiple components, reducing system complexity while maintaining security effectiveness.
3Reliability
If a barrier locking system is installed to create a safe zone, then security is improved, but installation complexity and storage requirements increase
Solution Approach 1:
The patent merges the lock rod and floor insert into a unified system where the lock rod fits directly into the floor insert, combining multiple functions (locking, securing, and releasing) into an integrated assembly. This merging simplifies installation as the components are designed to work together as a complete unit, reducing the number of separate parts that need to be installed and configured.
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
The system effectively restricts unauthorized entry while allowing quick access for authorized personnel, ensuring a secure yet accessible safe zone and compliance with safety codes, enhancing emergency response efficiency.
Implementation Method 1
a coil spring disposed around the lock rod, the coil spring configured to urge the lock rod vertically by abutting engagement of the bushing

AI summary
A manually activated locking device is provided to inhibit and restrict an entry/exit door from opening either outward or inward or both, as installed. In one aspect, the device that can be set from inside the room to be protected from threats or intrusion. In one aspect, the locking device is designed to be tamper-proof from outside the room yet allows access by authorized individuals thereby creating a secure but accessible safe zone for individuals or property inside the zone. In one aspect, the activated locking device may be mechanical system which may prevent hacking on the locking device.
