Wireless Lock Mechanism for Retail Fixture Theft Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retailers face challenges in securing small, expensive items from theft, as existing security measures are often ineffective against shoplifters who can detach or remove these items from display fixtures, and there is a need for a more efficient and secure method to manage and monitor these items in a retail environment.
Innovation Solution
A wireless security system that includes a lock with a plunger pin and cam mechanism, which can be transitioned between locked and unlocked states via a wireless authorization signal, and a portable computing device that provides this authorization, allowing for secure access and monitoring of items on display fixtures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical lock operated by a key is used to secure the security device to the display support, then the security device can be protected from theft, but the operation becomes cumbersome and requires physical key management
Solution Approach 1:
The patent replaces the mechanical key-based locking system with an electronic lock that uses electronic keys (such as RFID cards, key fobs, or mobile devices) to authenticate and control access. The electronic lock receives signals from the electronic key to actuate the locking mechanism, eliminating the need for physical keys and their associated management complexities while maintaining or enhancing security protection.
2Ease of operation
If an electronic lock operated by an electronic key is used to arm and disarm the security device, then the operation becomes more convenient, but the device complexity increases
Solution Approach 1:
The patent introduces an intermediary electronic key (such as an RFID card, key fob, or mobile device) that contains authentication credentials and communicates with the electronic lock. This intermediary handles the complex authentication logic and signal transmission, allowing the lock mechanism itself to remain relatively simple while still providing convenient electronic operation. The electronic key acts as a mediator between the user and the locking system.
3Reliability
If traditional security measures are used to protect small expensive items from theft, then basic protection is provided, but shoplifters can still detach or remove items from display fixtures
Solution Approach 1:
The patent merges the security device (display fixture) with the locking mechanism into an integrated system. The security device is designed so that the locking mechanism is inherently part of the fixture structure, making it difficult for shoplifters to detach or remove items without triggering the security system. This integration ensures that the display function and security function work together as a unified system, preventing the harmful factor of item detachment.

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 plunger pin configured to be moved between a latched position and an unlatched position, and wherein the fixture is configured to be accessed in the unlatched position. The lock comprises a cam configured to be moved between a locked state and an unlocked state for allowing the plunger pin to be moved between the latched position and the unlatched position when in the unlocked state, wherein the cam is configured to be moved in response to receiving a wireless authorization signal to transition the lock between the locked state and the unlocked state.
