RFID Cable Transponder for Connection Status Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for connecting and managing locally separated system devices, such as those using RFID transponders, cannot determine if a data connection is successfully established or if it meets required security and transmission standards, and cannot assess the properties of the connecting lines, particularly in cable management systems.
Innovation Solution
Incorporating an RFID cable transponder into the coupling elements of connecting lines, which can be read by an RFID reader to evaluate physical properties like attenuation, shielding, and manufacturer information, allowing for the assessment of connection status and compatibility with transmission requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard data cables are used for connecting system devices, then the connection can be established, but the connection status and transmission security cannot be determined
Solution Approach 1:
The patent embeds RFID transponders within cable connectors and coupling elements, creating a nested structure where the transponder is integrated into the existing cable assembly. This allows connection status monitoring to be incorporated into the standard cable connection without adding external monitoring devices, thus improving reliability while minimizing additional system complexity
Solution Approach 2:
The RFID transponder acts as an intermediary element between the cable connection and the monitoring system. It carries identification and property data that enables the reader to determine connection status and cable characteristics without requiring complex direct measurement systems, resolving the contradiction between reliability improvement and system complexity
2Measurement precision
If RFID transponders are added to cable connectors, then connection status can be determined, but the device complexity increases
Solution Approach 1:
The patent combines the RFID transponder with the cable connector and coupling elements into a single integrated assembly. The transponder, connector, and coupling elements work together as one unit, allowing precise cable property detection while avoiding the complexity of separate monitoring components. This merging approach enables measurement precision improvement without proportionally increasing device complexity
3Reliability
If cable properties are monitored continuously, then transmission security is ensured, but energy consumption increases
Solution Approach 1:
The system performs RFID reading operations periodically or on-demand rather than continuously monitoring cable properties. The reader can be triggered by connection events, diagnostic requests, or scheduled intervals, allowing transmission security to be maintained through periodic verification while significantly reducing energy consumption compared to continuous monitoring
Solution Approach 2:
The RFID transponder passively provides cable identification and property information when queried, without requiring active power consumption for transmission. The passive RFID technology allows the transponder to be read by the reader system without its own power source, reducing the overall energy consumption of the monitoring system while maintaining reliable cable property verification
