Security Connector Sense Loop for Retail Theft Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retail electronic devices are increasingly vulnerable to theft due to their smaller and lighter designs, and existing security solutions fail to provide effective and cost-efficient protection while allowing customer interaction and power supply.
Innovation Solution
A connector assembly with a cord comprising conductors and a conductive shield, where engagement members are electrically isolated from the shield, forming a sense loop that generates a security signal upon interruption, allowing for secure connection and power delivery to electronic devices.

Engineering Contradiction Analysis
1Weight of moving object
If electronic devices are made smaller and lighter to improve portability and customer appeal, then the devices become more vulnerable to theft
Solution Approach 1:
The connector is divided into separate functional components: engagement members for mechanical attachment, conductors for electrical connections, and a conductive shield for grounding. This segmentation allows each component to perform its specific function optimally while working together to provide both power delivery and theft protection.
Solution Approach 2:
The conductive shield acts as an intermediary element that provides a reference potential for detecting security events. By isolating the engagement members from the shield electrically, the system can use the shield as a mediator to detect when the connector is properly engaged or tampered with, without the engagement members themselves being part of the detection circuit.
2Reliability
If a security device is implemented to protect merchandise from theft, then the cost of the solution increases
Solution Approach 1:
The patent combines power delivery and security protection functions into a single connector assembly. The same conductors that provide power also serve as the sense loop for theft detection, eliminating the need for separate security hardware and reducing overall system cost and complexity.
Solution Approach 2:
The connector assembly performs multiple functions simultaneously: it provides mechanical engagement to secure the device, delivers power through the conductors, and enables theft detection through the sense loop formed by the isolated conductors. This multi-functionality reduces the need for additional components and lowers implementation costs.
3Ease of manufacture
If the engagement members are electrically connected to the conductive shield, then the manufacturing process is simplified, but the sense loop detection becomes unreliable
Solution Approach 1:
The electrical connection between the engagement members and the conductive shield is deliberately extracted or removed. By electrically isolating the engagement members from the shield, the system ensures that the sense loop formed by the conductors can reliably detect security events without interference from the shield's electrical potential.

AI summary
In one example, a connector assembly for providing security to an article of merchandise is provided. The connector assembly includes a cord having a plurality of conductors and a body portion connected to the cord. The connector assembly also includes a connection portion engaged with the body portion and including a plurality of engagement members. Each of the engagement members is electrically connected to a respective conductor in the cord, and the connection portion is configured to engage the article of merchandise to thereby electrically connect the engagement members to one another for establishing a sense loop through the conductors in the cord. Interruption of the sense loop is indicative of a security event.
