Electromagnetic Door Lock Rotary Catch Torque Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door locking mechanisms, particularly electromagnetic door locks, lack simplicity and cost-effectiveness, and fail to efficiently introduce a defined force into the locking mechanism to maintain the locked position.
Innovation Solution
A door locking device with a rotary catch featuring a pivoting body, lever body, and connecting body, where the pivoting body is connected to the lever body via a first and second joint, allowing the closing bearing surface to contact the first joint in the closed position, enabling the force to be received by the housing and maintaining the locked position through torque, either from external force or a spring device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional locking mechanism with multiple components is used, then the locking function is achieved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the locking body, lever body, and connecting body into an integrated mechanism where the locking body serves dual functions as both the locking element and the force transmission element. The connecting body merges the pivot and lever functions into a single component, reducing the total number of parts while maintaining the locking function.
Solution Approach 2:
The locking body serves multiple functions: it acts as the primary locking element, provides the bearing surface for force transmission, and works in conjunction with the lever body to provide both locking and actuation functions. This multi-functionality reduces the need for separate dedicated components.
2Reliability
If a complex electromagnetic door lock mechanism is used, then the locking function is achieved, but the manufacturing cost increases
Solution Approach 1:
By merging multiple functional components into fewer integrated parts, the patent reduces the number of manufacturing steps, assembly operations, and associated costs. The integrated locking and lever bodies require fewer separate manufacturing processes and simplify assembly procedures.
Solution Approach 2:
The mechanism is segmented into three main functional groups (locking body, lever body, connecting body) that can be manufactured separately and then assembled, allowing for optimized manufacturing of each component while maintaining overall simplicity and reducing total cost.
3Force
If the closing bearing surface contacts the first joint, then the force is efficiently transmitted to the housing, but the mechanism requires precise alignment
Solution Approach 1:
The mechanism uses dynamic alignment through the connecting body that links the pivot and lever bodies, allowing the bearing surface to automatically align with the first joint during operation. The pivoting motion enables self-alignment that compensates for manufacturing tolerances while maintaining effective force transmission.
Solution Approach 2:
The first joint acts as an intermediary element between the bearing surface and the force transmission path to the housing. This intermediate connection point provides a tolerance buffer that accommodates alignment variations while ensuring effective force transfer to the housing structure.
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 a simple, cost-effective mechanism to maintain the locked position by utilizing torque to prevent the rotary catch from rotating back into the unlocked position, ensuring reliable door locking with reduced operational complexity and increased efficiency.
Implementation Method 1
the rotary catch can be acted upon or is acted upon in particular by a torque
Implementation Method 2
the spacing between the pivot axis of the pivoting body and the pivot point of the first joint is smaller than the lever length of the lever body
