Logical Node Mapping for Device Update and Relocation Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device configuration management systems fail to consistently manage devices over time, especially when devices are updated or relocated, as they rely on device identification or location information, which can lead to difficulties in associating pre-update and post-update devices or devices before and after relocation.
Innovation Solution
A device configuration management apparatus that utilizes logical nodes, storing device ID and location information, and allows for updates to these associations, treating logical nodes as objects with location and device information as attributes, enabling flexible management of device configurations and associations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If device identification information is used as a key to manage device information, then device management is straightforward and simple, but it becomes impossible to associate and grasp device identification information about pre-update devices and post-update devices when devices are updated due to aging
Solution Approach 1:
The patent segments device identification into two distinct components: device ID (for individual device identification) and location ID (for position identification). This segmentation allows the system to separately track device identity and location, enabling history association through location ID persistence even when device ID changes during updates.
Solution Approach 2:
The patent introduces location ID as an intermediary element that mediates between device ID and historical records. When a device is updated and device ID changes, the location ID remains constant and serves as the linking key to associate pre-update and post-update device information, preserving the device lifecycle history.
2Reliability
If location information is used as a key to manage device information, then device relocation can be tracked, but it becomes impossible to associate and grasp devices before and after location changes when devices are relocated
Solution Approach 1:
The patent divides the identification system into device ID (identity component) and location ID (position component). This segmentation allows location information to change while device identity remains tracked through device ID, enabling reliable location tracking without losing device identity continuity during relocations.
Solution Approach 2:
The patent uses device ID as an intermediary to maintain device identity continuity across location changes. When a device is relocated and location ID changes, the device ID remains constant and links the device's historical records across different locations, preserving identity continuity.
3Stability of the object's composition
If fixed relationships between devices and locations are maintained, then data consistency is ensured, but the system cannot adapt to device updates or relocations over time
Solution Approach 1:
The patent implements a dynamic identification system where device ID and location ID can be independently updated. The system maintains data consistency through structured data structures while allowing flexible reassignment of device-location relationships, enabling adaptation to device updates and relocations without compromising data integrity.
Solution Approach 2:
The patent allows parameter changes in device configuration by enabling independent modification of device ID and location ID. The structured data structure preserves consistency while accommodating parameter changes, allowing the system to adapt to evolving device configurations and locations over time.

AI summary
A device configuration management apparatus includes a logical node information storage storing logical node information about a logical node that can be associated with a particular device and a particular location, the logical node information including for each of logical nodes a device ID for identifying the particular device and location information which is information for identifying the location, a network information storage storing network information as a set of information about an edge connecting two logical nodes, and a node update processer configured to perform processing for updating at least one of the device ID and the location information with regard to the particular logical node in the logical node information stored in the logical node information storage.
