RF Tag-Derived Endpoint Identifiers for Accurate Network Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in efficiently registering and verifying the location of endpoints within heterogeneous networks due to the use of redundant identifiers and the difficulty in reading unique identifiers after installation, leading to errors and complications in maintenance, upgrading, and replacement.
Innovation Solution
Endpoints derive their unique identifiers from attached RF tags through wired or wireless interfaces, allowing for non-redundant identifier generation and location determination using scanners, enabling accurate registration and verification post-installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If endpoints are preprogrammed with unique identifiers and registered before installation, then endpoint identification is established, but the process is time and labor intensive and errors are difficult to detect after installation
Solution Approach 1:
The system performs preliminary actions by attaching RF tags to endpoints before installation, but the actual registration is deferred until after installation when the endpoint is in its final location. This allows location determination to be performed accurately without requiring time-consuming pre-installation registration processes.
Solution Approach 2:
The patent replaces manual mechanical registration processes with automated RF tag scanning and wireless communication. Scanners automatically read RF tag identifiers and determine locations, eliminating the need for manual barcode reading and database entry, thereby reducing both time and potential for human error.
2Ease of operation
If RF tags are attached to endpoints, then wireless identification is enabled, but redundant identifiers are created leading to confusion in endpoint logistics
Solution Approach 1:
The system extracts only the necessary identifier information from the RF tags and uses it to generate or assign unique endpoint identifiers. Rather than maintaining multiple separate identifier systems, the solution consolidates identification by deriving endpoint identifiers from RF tag data, eliminating redundant identifier management.
Solution Approach 2:
The RF tag identifier serves multiple functions: it provides wireless identification capability and simultaneously serves as the basis for generating the unique endpoint identifier. This multi-functional approach eliminates the need for separate identifier systems and reduces overall system complexity.
3Ease of repair
If unique identifiers are read after installation, then maintenance and replacement become easier, but identifiers may be difficult or impossible to read after installation
Solution Approach 1:
The patent replaces optical reading methods (barcodes requiring line of sight) with RF tag scanning that uses electromagnetic fields. This allows identifiers to be read wirelessly without physical contact or line of sight requirements, making identifier detection easy even after endpoints are installed in difficult-to-access locations.
4Manufacturing precision
If endpoints are registered before installation, then location information can be captured, but errors in location assignment are difficult to detect and correct
Solution Approach 1:
The system performs preliminary preparation by attaching RF tags to endpoints before installation, but delays the actual location registration until after the endpoint is installed in its final location. This ensures location information is captured accurately from the correct position without requiring complex pre-installation verification processes.

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.
