Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mechanical linkages are used between main locking assemblies and remote locking assemblies to accommodate varying door heights and handle locations, then the lock can be adapted to different door configurations, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent replaces the mechanical linkage system with an electronic actuator that uses electrical signals to control remote locking assemblies. The electronic actuator receives signals from a control system and actuates the remote locks independently, eliminating the need for complex mechanical linkages while maintaining adaptability to different door configurations.
Solution Approach 2:
The electronic actuator serves multiple functions: it can actuate different types of remote locking assemblies (deadbolts, shoot bolts, flippers) and accommodate various door heights and handle locations through electronic control, making the system universal and adaptable without requiring different mechanical linkage designs for each configuration.
2Adaptability or versatility
If mechanical linkages are used between main locking assemblies and remote locking assemblies, then the lock can accommodate varying door heights, but the ease of manufacture and installation deteriorates
Solution Approach 1:
By replacing mechanical linkages with an electronic actuator system, the patent simplifies manufacturing. The electronic actuator is a standardized component that can be manufactured independently and installed in various door configurations without requiring custom mechanical linkage fabrication for each door height.
Solution Approach 2:
The system is divided into independent modules: the electronic actuator, the control system, and the remote locking assemblies. This segmentation allows each component to be manufactured separately using standardized processes, improving ease of manufacture while maintaining adaptability to different door heights through electronic configuration.
3Adaptability or versatility
If mechanical linkages are used to connect main and remote locking assemblies, then the lock system can function across different handle locations, but the device complexity increases
Solution Approach 1:
The patent eliminates the mechanical linkage system and replaces it with an electronic actuator that responds to electrical signals from a control system. This allows the remote locking assemblies to be actuated independently based on handle location and door configuration, reducing device complexity while maintaining compatibility with different handle locations.

Implementation Method 1
a motor configured to linearly move the drive bar along the longitudinal axis
Implementation Method 2
a leadscrew coupled to the motor and rotatable about a rotational axis by the motor; and a nut threadably engaged with the leadscrew and coupled to the drive bar, wherein upon rotation of the leadscrew by the motor, the drive bar linearly moves along the longitudinal axis via the nut

AI summary
An electronic remote lock actuator includes a face plate defining a longitudinal axis. A housing disposed adjacent to the face plate. A motor disposed in the housing, and a first drive bar configured to be linearly moveable along the longitudinal axis by the motor. The first drive bar includes a first end and an opposite second end. The first end is configured to be secured to a second drive bar of a mechanical remote lock assembly such that linear movement of the first drive bar is translated to linear movement of the second drive bar along the longitudinal axis.
