Pivoting Motorized Lockdown Bar for Doorway Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic lock designs for doorways lack a pivoting motorized lockdown mechanism that can be selectively actuated between locked and unlocked positions, failing to provide an efficient and economical solution for securing doorways.
Innovation Solution
An electronic lock bar system comprising a pivoting lockdown assembly with an upright stanchion member and a motorized lockdown bar that can move between a locked horizontal position and an unlocked vertical position, controlled by a keypad assembly for secure actuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional electronic lock is used, then the device complexity is low, but the security effectiveness and reliability are insufficient
Solution Approach 1:
The lockdown bar is designed to pivot between a horizontal locked position and a vertical unlocked position, transitioning from a static to a dynamic structure. This dynamic configuration allows the bar to effectively secure the doorway when horizontal while being easily retracted to vertical for access, thereby improving security effectiveness without requiring overly complex mechanisms.
Solution Approach 2:
The system is divided into distinct functional components: an upright stanchion member for support, a motorized lockdown bar for securing, and a keypad assembly for control. This segmentation allows each component to perform its specific function efficiently, improving overall reliability while keeping individual components relatively simple.
2Reliability
If a pivoting motorized lockdown bar is implemented, then the security effectiveness is improved, but the ease of operation may be reduced
Solution Approach 1:
The motorized lockdown bar is automatically actuated by the keypad assembly when the correct password is entered. The system serves itself by converting the electrical signal from the keypad into mechanical motion that pivots the bar between locked and unlocked positions, eliminating the need for manual manipulation and improving ease of operation.
Solution Approach 2:
The manual mechanical operation of traditional locks is replaced with an electric motor that pivots the lockdown bar. This substitution allows for easier operation through electronic password entry while maintaining the mechanical securing function, thereby improving both ease of operation and security effectiveness.
3Productivity
If existing electronic lock designs are used, then the manufacturing cost is low, but the productivity and security performance are insufficient
Solution Approach 1:
The motorized lockdown bar serves multiple functions: it acts as both a securing mechanism when horizontal and a retractable element when vertical. The upright stanchion member provides both structural support and mounting for the motor assembly. This multi-functionality improves security performance while avoiding the need for additional separate components, thereby controlling manufacturing costs.

AI summary
An electronic lock bar for doorways including a pivoting lockdown assembly, a lockdown support assembly and a keypad assembly. The pivoting lockdown assembly includes an upright stanchion member attached to ground where a motor is coupled on top. In the shaft of the motor a lockdown bar is coupled and rotates going across the door from a vertical position defining a safe mode to a horizontal position defining a lock mode when a password is typed on the inside keypad or outside keypad connected to the motor. The lockdown support assembly includes a holding station member. The holding station member is attached to the ground by means of the distal end thereof. On top of the holding station member a lockdown bar support is attached to maintain the lockdown bar blocked when the lock mode is activated, thereby securing the doorway.
