Conventional smart locks face complications in installation due to the complexity and time-consuming process of mounting the door mount mechanism, and they often fail to properly fit onto thumb turns of different sizes and locations on mechanical lock devices.
Innovation Solution
A door mount mechanism for smart lock systems featuring a casing, a rotatable component, and an intermediate coupling with adjustable and elastic segments that can fit various thumb turn sizes and locations, allowing for remote and manual rotation of the thumb turn through a motor-driven actuating unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional door mount mechanism is used, then the smart lock can be installed, but the installation process is complicated and time-consuming
Solution Approach 1:
The door mount mechanism is divided into separate modular components: a door mount body, a rotatable component, and an intermediate coupling. These segments can be independently manufactured and assembled, simplifying the overall installation process while maintaining structural functionality.
Solution Approach 2:
The intermediate coupling is designed to be nested within the door mount body, with the rotatable component housed within the intermediate coupling structure. This nested arrangement reduces the overall footprint and simplifies installation by eliminating the need for separate mounting brackets or additional structural elements.
2Adaptability or versatility
If a fixed door mount design is used, then the structure is simple, but it cannot properly fit onto thumb turns of different sizes and locations
Solution Approach 1:
The intermediate coupling incorporates a linearly movable second coupling segment that can dynamically adjust its position relative to the first coupling segment. This dynamic adjustment capability allows the door mount to adapt to thumb turns of various sizes and locations, transforming a static structure into a versatile, adaptable mechanism.
Solution Approach 2:
The door mount mechanism allows for parameter changes in the coupling geometry through the movable second coupling segment. By changing the relative position and orientation parameters of the coupling segments, the system can accommodate different thumb turn dimensions and mounting locations without requiring multiple specialized components.
3Adaptability or versatility
If a complex adjustable coupling is used to fit different thumb turns, then adaptability improves, but the device complexity increases
Solution Approach 1:
The intermediate coupling is designed with self-adjusting features where the movable second coupling segment automatically positions itself to accommodate the specific thumb turn geometry. This self-service capability eliminates the need for complex manual adjustment mechanisms or specialized installation tools, maintaining ease of operation while achieving high adaptability.

AI summary
A door mount mechanism is to be mounted onto a door for rotating a thumb turn of a door lock. The door mount mechanism includes a casing, a rotatable component and an intermediate coupling. The casing is for abutting against the door, and defines a receiving space that is adapted for receiving the door lock. The rotatable component is coupled rotatably to the casing. The intermediate coupling includes a first coupling segment connected co-rotatably to the rotatable component, and a second coupling segment connected co-rotatably to and linearly movable relative to the first coupling segment and for driving rotation of the thumb turn of the door lock such that the thumb turn is co-rotatable with the rotatable component.
