Dual RFID Access Housing for Barrier Status and User Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine safety systems in industrial operations lack an integrated solution for access control and user identification, often requiring separate devices and complex wiring, which can be cumbersome and inefficient.
Innovation Solution
A single housing with dual RFID sensors, one for access control by reading a movable barrier's status and another for user identification, integrated with a barrier access module and identification module, sends alerts and safety instructions to ensure safe machine operation based on authorized personnel presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate devices are used for access control and user identification, then each function can be performed independently, but the device complexity and wiring requirements increase
Solution Approach 1:
The patent combines access control and user identification functions into a single RFID sensor device. The housing contains both a first RFID sensor for reading access control tags and a second RFID sensor for reading user identification tags, eliminating the need for separate devices and reducing wiring complexity while maintaining functional reliability
Solution Approach 2:
The single housing device performs multiple functions: it controls access by reading barrier status tags and simultaneously identifies users by reading their RFID tags. This multi-functional approach reduces the number of devices needed while maintaining the reliability of both access control and user identification operations
2Ease of operation
If multiple separate devices are installed for access control and identification, then each device can be optimized for its specific function, but the installation complexity and wiring requirements increase
Solution Approach 1:
The patent merges access control and user identification into a single housing unit, reducing installation complexity by eliminating the need to install and wire multiple separate devices while maintaining ease of operation for both access control and user identification functions
3Device complexity
If a single integrated device is used for both access control and user identification, then device complexity is reduced, but the functional requirements become more demanding
Solution Approach 1:
The single housing device is designed with universal functionality to handle both access control and user identification. It includes a first RFID sensor for accessing barriers and a second RFID sensor for identifying users, allowing one device to adapt to multiple functional requirements without increasing complexity

Function Achieved in This Case
This integrated solution enhances safety and efficiency by allowing a single device to manage access and identification, reducing complexity and improving safety protocols within industrial enclosures.
Implementation Method 1
a first RFID sensor, located in the housing, configured to read a first RFID tag in close proximity to the first RFID sensor indicating a closed status of a movable barrier
Implementation Method 2
a second RFID sensor, located in the housing, configured to read a second RFID tag of an authorized person
Data Source
AI summary
A component includes a housing mounted at an entry point of an enclosure protecting a machine. The component includes a first RFID sensor, in the housing, that reads a first RFID tag in close proximity to the first RFID sensor indicating a closed status of a movable barrier of the enclosure at the entry point. Opening of the movable barrier allows entry to the enclosure. The component includes a second RFID sensor, in the housing, that reads a second RFID tag of an authorized person. The component includes a barrier access module that sends an open alert that the movable barrier is in an open state in response to the first RFID sensor not being close enough to read the first RFID tag, and an identification module that sends tag information unique to a person from the second RFID tag.
