Address Book Transfer via Intermediary Data Transmission Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in transferring and managing destination information across multiple Multi Function Peripherals (MFPs) when installing a destination management device, especially when the device cannot access an existing directory server, leading to increased trouble and inconvenience.
Innovation Solution
A data transmission system comprising a data transmission device and a destination management device connected via a network to a data storage device, where the data transmission device stores and transmits address books and destination information, and the destination management device receives and registers this information, allowing for seamless transfer without direct access to the directory server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a destination management device is newly installed to manage user-specific address books, then user privacy and address book management are improved, but the complexity of transferring destination information from the existing directory server increases
Solution Approach 1:
The data transmission device serves as an intermediary between the destination management device and the directory server. The destination management device requests address book information from the data transmission device, which then acquires the information from the directory server and forwards it to the destination management device. This mediator approach allows the destination management device to obtain necessary information without directly accessing the directory server, thus maintaining security while enabling functionality.
Solution Approach 2:
The data transmission device stores address book information in advance before the destination management device is installed. When the destination management device is installed, it can request and receive pre-stored address book information from the data transmission device, eliminating the need for manual transfer or direct directory server access during installation.
2Reliability
If the destination management device cannot access the directory server directly, then security and user privacy are maintained, but the ability to transfer destination information automatically is reduced
Solution Approach 1:
The data transmission device acts as an authorized intermediary that has permission to access the directory server on behalf of the destination management device. It retrieves address book information from the directory server and provides it to the destination management device, thus maintaining security constraints while enabling automatic information transfer.
Solution Approach 2:
The data transmission device automatically performs the task of acquiring and transferring address book information without requiring manual user intervention. When the destination management device requests address book information, the data transmission device autonomously retrieves it from the directory server and forwards it, making the process as automatic as possible within security constraints.

AI summary
When a destination management device requests an address book of each user, a data transmission device transmits the address book to the destination management device. The destination management device stores the address book received from the data transmission device. If location information of destination information is included in the address book, the destination management device transmits the location information to the data transmission device. The data transmission device transmits the location information to an LDAP server to request the destination information. Upon receipt of the destination information, the data transmission device transmits the destination information to the destination management device.
