Electronic Locking Apparatus for Swing Door with Solenoid Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an improved electronic door lock that effectively secures swing-type doors, as existing electronic locks are not adequately designed for this type of door configuration, lacking in secure access control and user authorization mechanisms.
Innovation Solution
An electronic locking apparatus is introduced, comprising a case, a linkage, and a solenoid, which engages with a latch bolt to block or allow access based on user authorization, utilizing a catch, cam, and release lever mechanism to transition between locked and unlocked positions, ensuring secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing electronic locks are used on swing doors, then basic locking function is provided, but secure access control and user authorization mechanisms are insufficient
Solution Approach 1:
The locking mechanism is divided into distinct functional components: a bolt for engagement, a linkage system with catch/cam/trigger elements for motion control, and a solenoid for actuation. This segmentation allows each component to perform its specific function efficiently while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
The linkage acts as an intermediary mechanism between the solenoid actuator and the bolt. It translates the linear motion of the solenoid into the appropriate bolt movement while providing mechanical advantage and controlled engagement through the catch, cam, and trigger elements, thereby enhancing security without requiring direct complex electronic control of the bolt itself.
2Reliability
If a simple latch mechanism is used, then ease of operation is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The latch mechanism is designed to be self-latching through the interaction of the catch and cam elements. Once the bolt is engaged, the mechanism automatically maintains the locked state without requiring continuous external force or complex control systems, providing both security and ease of operation.
Solution Approach 2:
The manual operation of the latch is replaced by an electrically actuated solenoid that automatically controls the bolt movement. This substitution eliminates the need for manual manipulation of complex locking mechanisms while maintaining high security through the mechanical linkage design that prevents unauthorized engagement or disengagement.
3Ease of operation
If the bolt is allowed to move freely, then ease of opening is improved, but unauthorized access becomes possible
Solution Approach 1:
The linkage mechanism provides mechanical feedback through the catch and trigger elements that ensure the bolt is properly engaged before allowing operation. The system responds to authorized input (solenoid actuation) by enabling bolt movement, while preventing unauthorized movement through the interlocking cam and trigger design that requires specific mechanical conditions to be met for operation.
Solution Approach 2:
The linkage serves as an authorized intermediary between the user's opening action and the bolt movement. It controls when and how the bolt can move, allowing free movement only when properly actuated by the solenoid in response to authorized access, thereby maintaining security while enabling ease of operation for authorized users.
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 solution provides secure and user-controlled access to swing doors by effectively blocking or allowing movement of the latch bolt, enhancing security and usability through electronic authorization mechanisms.
Implementation Method 1
a solenoid coupled to the case. The case is coupled to the frame to hold the locking apparatus on the frame. operation of the solenoid by an authorized user allows the linkage to move from the locked position to the unlocked position

AI summary
An electronic locking apparatus for an entryway, having a linkage coupled to an entryway frame case, and a solenoid associated with the case, the solenoid is configured to selectively engage with the linkage. The linkage is movable between a locked position blocking movement of a latch bolt from the latched position to the unlatched position and an unlocked position allowing movement of the bolt to the unlatched position.
