RF Tag-Derived Endpoint Identifiers for Location Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in accurately registering and verifying the location of endpoints within heterogeneous networks due to the use of redundant identifiers and the difficulty in reading unique identifiers post-installation, leading to errors and complications in maintenance, upgrading, and replacement.
Innovation Solution
Endpoints derive their identifiers from attached RF tags through wired or wireless interfaces, using algorithms to generate non-redundant identifiers, which are then registered with a controller, allowing for location detection and verification post-installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If endpoints use pre-programmed unique identifiers, then endpoint identification is established, but reading the identifier becomes difficult or impossible after installation
Solution Approach 1:
The patent introduces a scanner as an intermediary device that reads identifiers from RF tags attached to endpoints. The RF tag serves as a mediator between the endpoint's internal identifier and the external reading system, allowing non-contact identification after installation without compromising identifier accuracy.
Solution Approach 2:
The patent creates a copy of the endpoint identifier by printing it on a visible label or displaying it on a screen adjacent to the endpoint. This visual copy can be read after installation without modifying the original pre-programmed identifier, maintaining both readability and accuracy.
2Ease of operation
If RF tags are attached to endpoints, then post-installation identification becomes possible, but redundant identifiers are created
Solution Approach 1:
The patent merges the RF tag identifier with the endpoint's pre-programmed identifier by having the scanner read both and associating them in a database. This consolidation eliminates redundancy by creating a unified identifier system where the RF tag and original identifier refer to the same endpoint.
Solution Approach 2:
The system uses feedback mechanisms where the scanner reads the RF tag identifier, verifies it against the pre-programmed identifier in the database, and confirms proper endpoint installation. This feedback loop ensures identifier uniqueness while enabling post-installation identification.
3Ease of operation
If identifiers are printed on endpoint exteriors, then post-installation reading is enabled, but the identifier may be obscured
Solution Approach 1:
The scanner acts as an intermediary that can read identifiers from RF tags without line-of-sight requirements. This eliminates the obscuration problem by allowing identification through walls, panels, or other barriers that would block visual reading of printed identifiers.
Solution Approach 2:
The system provides multiple methods for identifier access: visual reading of printed labels for simple cases and RF tag scanning for obscured or complex installations. This multi-functional approach ensures identifier readability regardless of installation conditions.
4Loss of information
If manual registration of endpoints is performed, then location information can be recorded, but time and labor are consumed
Solution Approach 1:
The system enables self-service registration where the scanner automatically reads the RF tag identifier and retrieves location information from the database without requiring manual data entry. The endpoint essentially registers itself by presenting its RF tag to the scanner, dramatically reducing registration time while maintaining location accuracy.
Solution Approach 2:
The scanner provides immediate feedback by automatically verifying the RF tag identifier against the database and confirming proper registration. This automated feedback loop eliminates manual verification steps and ensures location information accuracy without increasing registration time.

AI summary
First information identifying a first one of a target circuit or a radio frequency (RF) tag is conveyed to a second one of the target circuit or the RF tag. Second information identifying the second one of the target circuit and the RF tag is then derived from the conveyed first information. The second information is then stored. In some cases, the first information is conveyed over a wired interface or a wireless interface between the target circuit and the RF tag. The first information identifying the RF tag can be conveyed to the target circuit, and second information identifying the target circuit can be derived based on the first information identifying the RF tag by equating the second information to the first information or applying a predetermined algorithm to the first information to generate the second information.
