Electronic Controlled Handle Motorized Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing latching and locking handles, such as Lift-Handle and T-Handle products, are vulnerable to vandalism and theft due to mechanical key issues like loss, copying, and theft, and there is a need for electronic control of the locking function while maintaining mechanical latching mechanism operation for retrofitting existing cabinets.
Innovation Solution
The integration of electronic control systems into Lift-Handle and T-Handle products, including a handle, housing, slider bolt, motor, CAM, circuit board controller, eye, handle sensor, and IRDA infrared transceiver, allows for electronic control of the locking function while maintaining mechanical latching operation, with the motor rotating the CAM 360 degrees to change the handle's state from locked to unlocked and the CAM maintaining the slider bolt in the locked position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical key lock plugs are used, then the handle can be operated to access the cabinet, but the lock plugs are vulnerable to vandalism and theft, and mechanical keys are subject to being lost, copied and stolen
Solution Approach 1:
The patent replaces the mechanical key lock plug system with an electronic motorized lock system. The electronic lock receives control signals electronically and actuates the latch mechanism through a motor, eliminating the need for mechanical keys and key-operated lock plugs. This substitution removes the vulnerabilities associated with mechanical keys being lost, copied, or stolen, while maintaining the ability to control handle operation.
2Extent of automation
If motorized latch and lock products are used to replace Lift-Handle and T-Handle products, then electronic control is achieved, but the mechanical latching mechanism function/operation is lost
Solution Approach 1:
The patent merges the electronic motorized lock control system with the existing mechanical latching mechanism. The motorized lock provides electronic control for locking and unlocking, while the mechanical latch mechanism (including the latch bolt and engagement surfaces) remains intact to perform the actual latching and unlatching function. This combination allows electronic automation while preserving the proven mechanical latching operation for retrofit applications.
3Reliability
If the latch mechanism is controlled manually by handle movement, then the mechanical latching mechanism operates reliably, but electronic control of the locking function is not achieved
Solution Approach 1:
The patent segments the locking and latching functions into separate systems. The electronic motorized lock handles the locking and unlocking control through electronic signals and motor actuation, while the mechanical latch mechanism handles the latching and unlatching through handle movement. This segmentation allows each subsystem to specialize in its function, achieving electronic control for security while maintaining reliable mechanical latching operation.

Function Achieved in This Case
This solution provides enhanced security by preventing unauthorized access through electronic key detection and motorized control, reducing vulnerability to theft and vandalism, while allowing for easy retrofitting of existing cabinets with improved closure systems.
Implementation Method 1
the motor serves to rotate the CAM by 360 degrees to change the state of handle from locked to unlocked to latched
Implementation Method 2
the slider bolt seats in the housing and is biased downward to the latched position by the one or more springs
