Door Bolt Module With Lockdown Button for Rapid Emergency Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bolting mechanisms lack the ability to rapidly secure doors in lockdown situations while also allowing for daytime access modes where the door can be unsecured unless a lockdown mode is activated.
Innovation Solution
A bolting mechanism with a lockdown button that primes bolts for rapid throwing and includes a plunger to block or release the drive members, allowing for a lockdown mode and a daytime mode with visual indicators for status awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a deadbolt or latch is used to block bolt movement, then security is improved, but the ability to rapidly throw bolts in lockdown situations is worsened
Solution Approach 1:
The system is divided into separate functional components: a plunger for blocking drive members, a button for releasing the plunger, and a bias mechanism for automatic resetting. This segmentation allows the security function (plunger blocking) to be separated from the rapid deployment function (button release), enabling both security and speed requirements to be met simultaneously.
Solution Approach 2:
The plunger is pre-positioned to block the drive members, and the bias mechanism is pre-loaded to automatically reset the plunger after release. This preliminary positioning ensures that when the button is pressed, the bolts can be thrown immediately without delay for manual resetting, achieving rapid lockdown while maintaining security.
2Reliability
If bolts are always thrown to secure the door, then security is improved, but ease of access during daytime is worsened
Solution Approach 1:
The system transitions from a static always-locked state to a dynamic system that can switch between locked and unlocked states. The plunger and button mechanism allows the drive members to be blocked when security is needed, and freely movable when daytime access is required, providing adaptability between security modes and access modes.
3Speed
If a plunger is used to block drive members, then rapid lockdown capability is improved, but device complexity is worsened
Solution Approach 1:
The bias mechanism automatically resets the plunger to its blocking position after the button is pressed and the bolts are thrown. This self-service resetting eliminates the need for manual intervention to reset the system, reducing operational complexity while maintaining the rapid lockdown capability provided by the plunger-button mechanism.
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
Enables rapid door securing in emergencies and provides a daytime mode with visual indicators for secure status, enhancing safety and usability.
Implementation Method 1
the plunger is biased by a bias member to engage with one of the drive members and block throwing of the at least one bolt
Implementation Method 2
a first bias arranged to drive the at least one first rotor to urge the at least one bolt to the thrown position

AI summary
A bolting mechanism with a lockdown mode is provided. The bolting mechanism includes at least one bolt, the bolt moveable between a thrown position for securing a door and a retracted position, at least one first rotor arranged to simultaneously drive the bolt and one or more drive members, a first bias arranged to drive the at least one first rotor to urge the bolt to the thrown position, and a lockdown assembly comprising a lockdown button and plunger. The plunger is movable between a blocking position and a retracted position wherein the plunger is biased by a second bias to engage with one of the drive members and block throwing of the at least one bolt. The lockdown button is arranged to release the plunger so the first bias throws the bolt or primes the bolt ready to be urged to the thrown position.
