Merchandise Security System with Unique Decoding Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current open display merchandise security systems lack unique decoding data for each device, leading to poor anti-theft performance and inadequate data collection for managing and verifying usage and theft incidents.
Innovation Solution
A merchandise security system with a data management unit that synchronizes unlocking data and judgment data across alarm units, enabling unique unlocking codes for each device and collecting usage history and user interaction data to enhance security and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the same decoding data is used for all open display merchandise security devices, then the ease of operation is improved, but the reliability is worsened
Solution Approach 1:
The patent divides the decoding data into unique segments for each security device. Each alarm unit is assigned a distinct decoding data identifier, so that instead of one universal key, each device has its own specific key. This segmentation ensures that unlocking one device does not affect others, thereby improving reliability while maintaining operational ease through standardized access procedures.
Solution Approach 2:
The patent implements local quality by assigning different decoding data to different locations or devices. Each alarm unit has locally unique decoding characteristics, allowing customized security levels for different merchandise or display areas. This enables high-security zones to have more restricted access while other areas maintain convenient access, resolving the contradiction between ease of operation and reliability.
2Ease of operation
If a single key can unlock all security devices, then the ease of operation is improved, but the loss of information is worsened
Solution Approach 1:
The patent implements feedback mechanisms through data collection units that record and store information about each unlocking operation. When a device is unlocked, the system captures data including which key was used, when it occurred, and which device was accessed. This feedback loop preserves verification information while maintaining operational convenience, as users can still unlock devices easily but the system retains audit trails for later verification and analysis.
3Reliability
If unique decoding data is assigned to each security device, then the reliability is improved, but the device complexity is worsened
Solution Approach 1:
The patent applies universality by designing a multi-functional data collection unit that handles multiple tasks: storing unique decoding data, recording unlocking operations, capturing user information, and generating verification reports. This single unit performs what would otherwise require multiple separate components, thereby improving reliability through unique device identification while minimizing the increase in system complexity through functional integration.
4Loss of information
If data collection functions are added to security devices, then the loss of information is reduced, but the device complexity is worsened
Solution Approach 1:
The patent merges the data collection functionality with the existing alarm and decoding units. The data collection unit is integrated into the alarm unit structure, sharing hardware resources and processing capabilities. This combining approach allows comprehensive data collection including unlocking records, user information, and operational status without requiring entirely separate systems, thus reducing information loss while controlling the increase in device complexity.
Data Source
AI summary
A merchandise security system with data collection features and a relevant method are disclosed. The system has: a data management unit, at least one alarm unit and at least one alarm disabling unit, wherein the data management unit is configured to synchronize unlocking data in the alarm disabling unit and set unlocking judgment data in the alarm unit; the alarm unit can detect, in an alarm enabled state, whether a merchandise to be protected is in a normal state, and send out an alarm signal when judging that the merchandise to be protected is not in a normal state; and the alarm unit judges, according to the unlocking judgment data stored therein, whether the unlocking data is legitimate, and disable the alarm enabled state when judging that the unlocking data is legitimate. In the present disclosure, each of the unlocking judgment data corresponds to unique legitimate unlocking data embedded in the alarm disabling unit. The alarm unit can realize a data collection function, and can not only collect information related to enabling an alarm and disabling the alarm, but also can collect other data related to user behaviors for later data analysis.
