Passive RFID Tag for Lockset Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems lack integration of passive RFID tag solutions, limiting their ability to provide efficient and user-friendly control over mechanical locking assemblies in residential and commercial settings.
Innovation Solution
A system comprising a lockset with a passive RFID tag affixed to a housing, leveraging a mobile device's reader to scan the tag, transmit notifications, and issue commands to a home automation controller, enabling remote control and automation of locking mechanisms without the need for an integrated RFID tag reader.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing security systems use integrated RFID tag readers, then they can control mechanical locking assemblies, but the device complexity and cost increase
Solution Approach 1:
The patent extracts the RFID reader function from the locking device and places it in a separate mobile device. The locking device only contains the passive RFID tag and mechanical locking assembly, while the mobile device handles all reader functionality, notification transmission, and cloud service updates. This separation reduces the complexity of the locking device while maintaining full control capabilities.
Solution Approach 2:
The mobile device serves multiple functions: it acts as an RFID reader, notification transmitter, cloud service updater, and home automation controller. By consolidating these functions in a universal device that users already possess, the system avoids adding dedicated components for each function, thereby reducing overall system complexity.
2Extent of automation
If passive RFID tags are integrated into locking devices, then automation capability improves, but manufacturing complexity increases
Solution Approach 1:
The system segments the automation functionality into two parts: a simple passive RFID tag affixed to the locking device housing (easy to manufacture) and an active mobile device that performs all reading, processing, and automation control functions. This segmentation allows the locking device to maintain simple manufacturing while achieving high automation capability through the external mobile device.
3Productivity
If existing systems require manual credential verification, then device complexity is low, but productivity and user convenience decrease
Solution Approach 1:
The system enables self-service access control where the mobile device automatically scans the passive RFID tag, retrieves user credentials from cloud services, verifies authorization, and triggers locking mechanism operation without requiring manual credential entry or verification by security personnel. This automated self-service process significantly improves productivity while the distributed architecture keeps individual device complexity low.
