Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retailers face challenges in securing merchandise from theft, as small and relatively inexpensive items are attractive targets for shoplifters, and existing security systems may not effectively prevent theft or manage access.
Innovation Solution
A merchandise security system that includes a plurality of locks configured to wirelessly communicate with mobile computing devices, using multiple communication protocols to establish and verify authorization for unlocking specific locks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple communication protocols are used for lock identification and unlocking, then security against unauthorized access is improved, but device complexity increases
Solution Approach 1:
The communication process is divided into two distinct phases using different protocols: first, Bluetooth Low Energy (BLE) is used for initial lock identification and pairing, then Near Field Communication (NFC) is used for secure authentication and unlocking. This segmentation allows each protocol to be optimized for its specific function, improving overall security while managing complexity through clear protocol separation.
Solution Approach 2:
The mobile device acts as an intermediary between the user and the lock system. It first communicates with the lock via BLE to identify the target lock, then uses NFC to authenticate and trigger unlocking. This intermediary approach allows complex multi-protocol communication to be managed through a single user interface, reducing the perceived complexity for end users.
2Ease of operation
If wireless communication with mobile devices is implemented, then ease of operation is improved, but reliability of security control may worsen
Solution Approach 1:
The traditional mechanical key system is replaced with wireless communication protocols (BLE and NFC). The mobile device communicates with the lock electronically, eliminating the need for physical key insertion and mechanical tumblers. This substitution maintains ease of operation through contactless interaction while improving security through encrypted digital authentication protocols.
Solution Approach 2:
The system incorporates feedback mechanisms where the lock provides status information to the mobile device during the authentication process. The mobile device receives confirmation signals from the lock to verify successful authentication and triggering, ensuring that the security control remains reliable even though the interface is wireless and contactless.

AI summary
Merchandise security systems and methods are provided. In one example, a merchandise security system includes a plurality of locks configured to protect one or more items from theft, each of the plurality of locks configured to wirelessly communicate with one or more mobile computing devices. Each of the plurality of locks is configured to establish communication with one or more of the mobile computing devices using a first communication protocol. Each of the plurality of locks is configured to subsequently communicate with one or more of the mobile computing devices using a second communication protocol, different than the first communication protocol, for identifying one or more of the plurality of locks to be unlocked. The one or more of the plurality of locks identified by the one or more mobile computing devices is configured to be unlocked in response to subsequently communicating with the one or more of the plurality of locks using the first communication protocol.
