Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cam lock systems require physical presence to lock or unlock, lacking remote control functionality, which compromises security and privacy.
Innovation Solution
A remotely-controllable, power-activated cam lock system incorporating a retractable geared plate, micro gear motor, controller, and power system, allowing locking and unlocking via remote control or manual key operation, with communication protocols for secure signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional manual cam lock system is used, then the structure is simple and reliable, but remote control functionality is lost and security is compromised
Solution Approach 1:
The patent combines a traditional cam lock mechanism with an electronic actuator package, merging manual and power-activated locking systems into a single integrated unit. The actuator package includes a motor, controller, and power system that work together with the cam lock to provide both remote and manual operation capabilities.
Solution Approach 2:
The cam lock system is designed to perform multiple functions: it can be operated remotely via wireless signals, controlled through a key-operated switch, or manually operated by turning the cam lock itself. This multi-functionality allows the same system to adapt to different operational needs and scenarios.
2Extent of automation
If power-activated locking is implemented, then remote control is enabled, but the system becomes dependent on power supply
Solution Approach 1:
The system includes a key-operated switch that allows preliminary manual engagement of the locking mechanism. This ensures that even if the power system fails, the locking function can still be activated or deactivated through manual operation of the cam lock and switch.
Solution Approach 2:
The patent maintains different operational modes for different situations: power-activated mode for convenient remote operation when powered, and manual key-operated mode for reliability when power is unavailable. Each mode has its own control mechanism optimized for its specific function.
3Adaptability or versatility
If multiple control methods are added, then versatility is improved, but device complexity increases
Solution Approach 1:
The control system is segmented into independent components: a wireless receiver for remote control, a key-operated switch for manual electrical control, and the mechanical cam lock for direct manual operation. Each component can function independently, allowing versatility without requiring all components to work together as a complex integrated system.
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
Enables secure, remote operation of cam locks with automatic locking and manual override, ensuring security and privacy even when the power system fails, using various communication protocols and power sources.
Implementation Method 1
a micro gear motor configured to drive the plate back and forth
Implementation Method 2
the controller is configured to receive a control signal from the remote control to activate/deactivate the micro gear motor accordingly
Implementation Method 3
the cam lock and the metal plate rotates with the key, generally ±90°, to engage or disengage with a catch or slot
Data Source
AI summary
In general, the present invention is incorporated in a cam lock housing that is securable relative to a drawer or door. Coupled to the cam lock housing is an actuator package. The actuator package of this exemplary cam lock system can include a retractable geared plate or tongue, a micro gear motor, a controller, and a power system. In operation, the drive gear/pinion causes lateral displacement of tongue towards or away from a latch in order to lock or unlock the item. As such, a medicine cabinet (or similar), can be remotely locked or unlocked. Alternatively, rotation of a physical key within the cam lock rotates the cam lock housing and the tongue towards or away from a latch so that the cam lock can also be operated manually.
