Transponder-Based Life Cycle Management for Network Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The management of the life cycle of distributed network devices, including repair, reuse, and recycling, is complex due to the need for reliable and efficient tracking and maintenance across networks, especially when communication links between devices and central management units become unavailable.
Innovation Solution
A life cycle network management system that employs transponders attached to network devices to store and update life cycle data, allowing for periodic or event-driven updates, and includes an interrogation unit that can read and forward this data even when communication links are unavailable, using either passive or active transponders and integrating with handheld devices for data processing and reestablishing communication links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transponder with memory is attached to each network device to store life cycle data locally, then data availability and reliability are improved during communication outages, but device complexity and manufacturing costs increase
Solution Approach 1:
The system segments the data storage function by attaching a separate transponder with memory to each network device. This transponder stores life cycle data locally on the device itself, independent of the central management unit. This segmentation ensures that data remains available even when communication links fail, as the data is distributed across individual devices rather than centralized.
Solution Approach 2:
The transponder acts as an intermediary between the network device and the central management unit. It buffers life cycle data locally and only communicates with the central unit when the communication link is available. This intermediary function decouples the data storage from the central management system, maintaining reliability during outages while allowing centralized management when possible.
2Productivity
If life cycle data is stored and updated locally on network devices, then maintenance and recycling operations can proceed during communication outages, but the system requires additional components and infrastructure
Solution Approach 1:
The system performs preliminary action by pre-storing life cycle data locally on each network device's transponder before communication outages occur. This includes pre-recording operational status, maintenance history, and recycling information. When outages happen, maintenance operations can immediately access this pre-stored data without needing to communicate with the central system, improving maintenance efficiency and productivity.
3Use of energy by moving object
If passive transponders are used to reduce power consumption, then energy efficiency is improved, but reading data requires active interrogation which may increase operational complexity
Solution Approach 1:
Passive transponders implement self-service by storing data locally and only activating when interrogated by a reader. They consume no power during normal operation, drawing energy only momentarily when a reader actively queries them. This approach minimizes overall power consumption while the interrogation-based reading mechanism, though requiring active scanning, simplifies the transponder design and reduces operational complexity on the device side.

AI summary
A life cycle network management system for performing life cycle management of distributed network devices, each network device comprising a communication link to a central network management unit and an attached transponder configured to store life cycle data of the network device updated by said network device, wherein if the communication link between the network device and the central network management unit is at least temporarily unavailable the updated life cycle data of the network device stored in the attached transponder is read by an interrogation unit of the life cycle network management system and processed to provide a life cycle management result.
