Device Management System Position-Based Identifier Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device management systems fail to accurately manage devices when their identifying information changes, such as during board replacements, leading to devices being identified as different entities despite being the same.
Innovation Solution
A device management system that includes a position management device and a device management device, where the position management device associates first device identifying information with positional information, and the device management device generates second device identifying information based on acquired first information, updating both when matching positional information is found, ensuring seamless management even with changes in identifying information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device identifying information is used to manage devices, then devices can be uniquely identified and managed, but when device identifying information changes (e.g., board replacement), the device is incorrectly determined as a different device
Solution Approach 1:
The patent introduces position information as an intermediary element that bridges the gap between device identifying information and device management. Instead of relying solely on device identifying information that may change, the system uses position information (location, coordinates, spatial data) as a stable reference point to associate with devices. This intermediary allows the system to maintain continuous device management even when device identifying information changes, by linking position information with both the old and new device identifiers.
2Measurement precision
If device management information is tied to specific device identifying information, then accurate device tracking is achieved, but device management information cannot be transferred when devices are replaced or modified
Solution Approach 1:
The patent implements preliminary action by pre-establishing position information for devices before any changes occur. The system proactively associates position information with device identifying information in advance, creating a stable reference framework. When device replacement or modification occurs, the system can immediately transfer management information by matching position information, eliminating the need for time-consuming manual re-registration or information transfer processes.
3Reliability
If the system requires additional charging processes for device information updates, then data consistency is maintained, but operational efficiency and simplicity are reduced
Solution Approach 1:
The patent implements self-service by enabling the system to automatically maintain data consistency without requiring additional manual charging processes. The position information acts as a stable key that automatically links device identifying information across changes. When device identifiers change, the system autonomously transfers management information by matching position information, eliminating the need for manual intervention or additional charging processes while maintaining data consistency.
Data Source
AI summary
A device management device that manages multiple devices, the device management device includes circuitry configured to generate second device identifying information of a given device based on first device identifying information that uniquely identifies the device and positional information representing the position of the device and, when positional information that matches the acquired positional information is managed, update the first device identifying information and the second device identifying information that are associated with the managed positional information respectively by using the first device identifying information and the generated second device identifying information.
