Offline Image Printer Subscription via Mediator Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional subscription services for image forming apparatuses require internet connectivity to determine availability, excluding users without suitable infrastructure or those who prefer offline usage.
Innovation Solution
A management system comprising an image forming apparatus, a server, and a communication terminal that allows offline operation by transmitting usage situation and contract information between the communication terminal and the server, enabling availability determination and service provision without internet connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image forming apparatus is connected to the Internet for availability determination, then the subscription service can be properly managed and monitored, but users without Internet access or suitable infrastructure cannot use the service
Solution Approach 1:
The communication terminal acts as an intermediary between the image forming apparatus and the server. It collects usage situation information from the offline image forming apparatus, transmits it to the server for availability determination, and receives control instructions back. This mediator enables subscription service management without requiring direct Internet connectivity from the image forming apparatus itself.
2Ease of operation
If the image forming apparatus communicates directly with the server, then availability determination is straightforward, but the apparatus must have network connectivity which excludes offline users
Solution Approach 1:
The system is segmented into three functional components: the image forming apparatus (which remains offline and simple), the communication terminal (which handles network communication and data collection), and the server (which performs availability determination). This segmentation allows the image forming apparatus to stay simple and offline while still enabling comprehensive service management through the other components.
3Object-affected harmful factors
If the image forming apparatus is kept offline for user privacy and security, then network security risks are reduced, but the service provider cannot monitor usage and manage subscriptions
Solution Approach 1:
The communication terminal serves as a secure intermediary that collects usage situation information from the offline image forming apparatus and transmits it to the server. This approach maintains the offline status of the image forming apparatus (reducing security risks) while still enabling the service provider to obtain necessary usage information for subscription management through the terminal's mediation.

AI summary
A mechanism capable of providing a subscription service of an available image forming apparatus even when the image forming apparatus is in an offline state is provided. In a management system, a communication terminal transmits usage situation information of an image forming apparatus and contract information to a service management server via a device management server based on information obtained from the image forming apparatus. The service management server performs an available-or-not determining processing of the image forming apparatus based on the received usage situation information and the received contract information, and transmits the result of the available-or-not determining processing to the communication terminal via the device management server. In the case that the result of the available-or-not determining processing that has been received indicates that the image forming apparatus is available for use, the communication terminal issues a usage restriction release instruction to the image forming apparatus.
