Bi-Swing Door Lock Arm and Catch Without Magnetic Locks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking systems for bi-swing doors require a magnetic lock device in combination with a solenoid, which is not entirely satisfactory, and there is a need for a more effective locking mechanism that does not rely on such components.
Innovation Solution
An electronic lock system featuring a frame, an electronic lock mechanism with an arm and a linear actuator, which moves between a door lock and release position, and a catch that selectively engages the arm to restrict its movement, without the need for a magnetic lock device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic lock device is used in combination with a solenoid to lock bi-swing doors, then the locking function is achieved, but the device complexity increases
Solution Approach 1:
The patent removes the magnetic lock device from the traditional combination system, extracting only the solenoid component to perform the locking function. The solenoid directly actuates the arm to engage with the door, eliminating the need for magnetic locking components while maintaining effective door security.
Solution Approach 2:
The solenoid is designed to perform multiple functions: it actuates the arm for door locking, engages the catch mechanism, and controls the release of the door. This multi-functional design replaces the need for separate magnetic lock and solenoid components, reducing overall system complexity while maintaining reliability.
2Reliability
If a magnetic lock device and solenoid combination is used, then door security is maintained, but the system requires more components
Solution Approach 1:
The patent merges the functions of the magnetic lock device and solenoid into a single solenoid-based mechanism. The solenoid directly controls the arm movement and catch engagement, combining what were previously separate components into one integrated system that maintains door security with fewer parts.
Solution Approach 2:
The solenoid system is designed to self-containedly perform all locking and release functions without requiring a separate magnetic lock device. The solenoid's electromagnetic field directly actuates the mechanical components, creating a self-sufficient system that reduces component count while maintaining security effectiveness.
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 locks and releases bi-swing doors selectively, enhancing security by preventing unauthorized access without relying on magnetic locks, thus improving the design of known locking mechanisms.
Implementation Method 1
The linear actuator moves between a system lock position and a system release position. In the system release position, the linear actuator presses against the arm to move the arm to the door release position.

AI summary
Electronic lock systems including a frame and an electronic lock mechanism operatively mounted to the frame. The electronic lock mechanism includes an arm and a linear actuator. The arm moves between a door lock position engaging a door and a door release position spaced from the door. The linear actuator moves between a system lock position and a system release position. In the system release position, the linear actuator presses against the arm to move the arm to the door release position. In some examples, the electronic lock system includes a catch disposed proximate to the arm. The catch is configured to selectively engage the arm to restrict the arm from moving and to selectively allow the arm to move.
