Motorized Lock Assembly with Cam-Driven Slider
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locks with rotatable handles and lock cores require a large inventory of spare parts due to numerous tumbler configurations and are labor-intensive to replace, especially when keys are lost or duties change.
Innovation Solution
A lock system featuring a handle assembly and lock actuating assembly with a motor-driven slider and cam mechanism that selectively positions the lock between locked and unlocked configurations, using outward locking plugs to align with radial bores, allowing for efficient rotation and simplifying the locking and unlocking process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional locks use multiple tumbler configurations to provide security, then security is improved, but the number of spare parts and inventory requirements increases
Solution Approach 1:
The lock core is designed with a universal structure that can work with multiple handle assemblies. The cam mechanism and actuator system are standardized across different lock configurations, allowing a single lock core design to serve multiple security applications without requiring different tumbler configurations for each application.
2Reliability
If conventional locks use complex tumbler configurations for security, then security is improved, but the difficulty and time required for lock replacement increases
Solution Approach 1:
The lock system is divided into separable components: the lock core, handle assembly, cam mechanism, and actuator. This segmentation allows the lock core to be independently replaced without replacing the entire lock assembly. The standardized interfaces between components enable quick removal and installation, reducing replacement time while maintaining security through the durable lock core design.
3Device complexity
If conventional locks use manual key-operated mechanisms, then simplicity is improved, but automation and efficiency are reduced
Solution Approach 1:
The lock system incorporates an electric motor that can be controlled to provide automated locking and unlocking operations. The motor drives the cam mechanism to move the actuator between locked and unlocked positions. This dynamic addition allows the system to operate in multiple modes: fully manual, fully automated, or semi-automated, depending on control signals received from external systems.
4Ease of operation
If conventional locks use manual operation only, then ease of operation is improved, but productivity and efficiency are reduced
Solution Approach 1:
The motorized actuator system can automatically perform the locking and unlocking operations without requiring manual key insertion or turning. The system can be controlled remotely or through automated access control systems, eliminating the need for human intervention in routine locking operations. This self-service capability significantly improves productivity in applications where multiple locking operations are performed frequently.
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
Reduces the need for multiple spare parts and simplifies the replacement process by using a motor-driven mechanism to efficiently switch between locked and unlocked states, minimizing labor and inventory requirements.
Implementation Method 1
The one of a slider and a second rotating cam is associated with the actuator, and configured to selectively direct the lock assembly between the locked and unlocked configuration, and having a cam profile.

AI summary
A lock with a handle assembly and a lock articulating assembly. The handle assembly has a handle member and a lock assembly. The handle member has a central bore and a locking plug groove. The lock assembly has a lock arm with a body positionable within the central bore. The body includes a central bore and a radial bore which is alignable with the locking plug groove. The lock assembly further has an outward locking plug configured to translate along the radial bore and selectively into the locking plug groove. The lock articulating assembly includes a slider (or a second cam), an actuator, a cam coupled to a motor. The cam is selectively engageable with the slider to rotate and/or translate the slider. The actuator is coupled to the slider, so that movement to the slider imparts movement of the actuator.
