Lock Actuation System with Integrated Coupling for Low-Profile Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door locking systems with integrated authentication mechanisms have a high structural height, limiting their installation to flush with the door surface and preventing use in tubular frame doors due to their overall height, which restricts their application.
Innovation Solution
A lock actuation system with a functional carrier, a door operating part, and a coupling mechanism where the coupling element can transition from a non-contact to a contact position with a counter-coupling element, integrated within a bearing element, allowing torque transmission while minimizing the system's overall height by integrating the coupling element into the bearing element and dividing the function carrier into distinct functional areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the coupling element is integrated into the bearing element, then the overall height of the system is reduced, but the structural complexity increases
Solution Approach 1:
The coupling element is integrated into the bearing element, merging two separate components into one unified structure. This reduces the overall height of the system while maintaining the functional separation through internal design, resolving the contradiction between compactness and structural clarity.
Solution Approach 2:
The coupling element is nested within the bearing element, allowing one component to be housed inside another. This nesting approach minimizes the external dimensions and overall height of the system while preserving the distinct functional areas internally.
2Length of stationary object
If the system is designed with low overall height, then it can be installed in tubular frame doors, but the mounting space for electronic components is reduced
Solution Approach 1:
The functional carrier is interrupted in its outer contour to create functional areas, effectively utilizing the available space in a two-dimensional layout rather than requiring additional height. This allows electronic components to be mounted within the planar functional areas while maintaining a low-profile overall structure.
Solution Approach 2:
Different functional areas are created within the functional carrier by interrupting its outer contour, allowing specific regions to be optimized for different purposes (e.g., card reader, electronics mounting). This local differentiation maximizes the utility of the limited space available in the low-height design.
3Adaptability or versatility
If the functional carrier is interrupted to create functional areas, then antenna placement is improved, but the structural integrity is reduced
Solution Approach 1:
The functional carrier is segmented into different functional areas by interrupting its outer contour. This segmentation allows optimal placement of antennas and electronic components in specific zones while maintaining the overall structural framework, balancing functional versatility with structural integrity.
