Cam-Sleeve Merchandise Display Locks with Wireless Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retail items, particularly small and expensive ones, are vulnerable to theft due to inadequate security measures, such as mechanical or electronic locks that can be easily bypassed by shoplifters.
Innovation Solution
A security system featuring an electronic key and merchandise security devices with a lock mechanism that includes a drive shaft and cam sleeve, controlled by a computing device for wireless authorization, allowing secure transition between locked and unlocked states, and a networked system for data communication and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical or electronic locks are used to secure merchandise, then theft protection is provided, but the locks can be easily bypassed by shoplifters
Solution Approach 1:
The patent replaces traditional mechanical or electronic key-based locking systems with a biometric authentication system. The lock mechanism uses fingerprint sensors to verify user identity and control the locking/unlocking of merchandise displays. This substitution of mechanical/electronic key systems with biometric technology provides more reliable theft protection that cannot be easily bypassed, as biometric data is unique to each individual and difficult to replicate.
Solution Approach 2:
The patent introduces a controller as an intermediary between the user and the lock mechanism. The controller receives biometric data from the sensor, processes authentication, and then activates the motor to unlock the display. This intermediary layer adds security by separating the authentication function from the locking function, preventing direct manipulation of the lock mechanism and making bypass attempts more difficult.
2Reliability
If secure locking mechanisms are implemented, then merchandise protection is improved, but access control complexity increases
Solution Approach 1:
The patent integrates multiple functions into a single compact device: the fingerprint sensor serves as both the authentication mechanism and the user interface, the motor provides both locking and unlocking functions, and the controller manages authentication, motor control, and status monitoring. This multi-functionality reduces overall system complexity compared to having separate components for each function, while maintaining strong merchandise protection.
Solution Approach 2:
The patent combines the biometric sensor, motor actuator, controller, and power management into an integrated lock assembly that is mounted directly on the merchandise display. By merging these components into a unified system rather than having separate authentication and locking systems, the patent simplifies installation and reduces the complexity of coordinating multiple independent systems while providing robust merchandise protection.

AI summary
Security systems and methods are provided. In one example, a security system includes at least one lock configured to protect one or more items from theft from the fixture, wherein the lock comprises a drive shaft configured to be moved between a latched position and an unlatched position, the fixture configured to be accessed in the unlatched position. The lock is configured to be moved between a locked state and an unlocked state for allowing the drive shaft to be moved between the latched position and the unlatched position when in the unlocked state, wherein the lock includes a cam sleeve having an internal cam surface configured to transition the lock between the locked state and the unlocked state in response to movement of the cam sleeve.
