Terminal Device Replacement Request With History Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device management systems face issues when replacing devices, as information succession can be defective, leading to outdated data, and existing solutions do not effectively manage device identification and usage history transfer without server intervention.
Innovation Solution
A device management system with a server and terminal device configuration that allows direct device identification and history data transfer between devices, enabling the server to update management information upon receiving a replacement request with the latest device identification and usage history, ensuring accurate and efficient device replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device information is transferred through the server during device replacement, then the server can maintain centralized control and update management information, but the usage history data may become outdated or incomplete before the transfer occurs
Solution Approach 1:
The terminal device obtains the usage history from the first device before submitting the replacement request to the server. This preliminary action ensures that the latest usage history is captured and attached to the replacement request, eliminating the time delay and ensuring accuracy of the transferred information.
2Loss of information
If the terminal device obtains usage history directly from the first device without server intervention, then the latest data can be captured, but the server cannot automatically update its management information
Solution Approach 1:
The patent combines two operations into one: the terminal device both obtains the usage history from the first device and submits it to the server in a single replacement request process. This merging ensures that the server receives complete and up-to-date information while maintaining automation, as the terminal device handles the data collection and submission in one coordinated action.
Solution Approach 2:
The terminal device acts as an intermediary between the first device and the server. It collects the usage history from the first device, attaches it to the replacement request, and submits it to the server. This intermediary role ensures that the server receives complete information without needing to directly interact with the first device, maintaining automation while ensuring data completeness.
3Productivity
If multiple pieces of information are transferred in a single replacement request, then the process is efficient and streamlined, but the complexity of processing the request increases
Solution Approach 1:
The replacement request is designed as a universal data structure that can accommodate multiple types of information (device identification, usage history, and other relevant data) in a standardized format. This multi-functional request structure allows the server to process various types of information through a single, unified processing pathway, maintaining efficiency while managing complexity through standardization.

AI summary
In a device management system, a terminal device receives a replacement instruction from a user when an acceptance condition is satisfied, and obtain first device identification information before the replacement, second device identification information after the replacement, first history information representing usage history of the first device from the first device without going through the server. The terminal device then transmits, to the server, a replacement request containing the first device identification information, the second identification information and the first history information. In a case where an allowance condition is satisfied, the server stores, in the storage of the server, second management information representing a relationship among the first management identification information associated with the first device identification information by the first management information, the first history information and the second device identification information.
