Extension Service Management Unit for Image Forming Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack an efficient mechanism to provide functions beyond standard capabilities without relying on standard applications, limiting customization and integration of additional services.
Innovation Solution
An electronic device with a first and second extension service, managed by an extension service management unit, which notifies and executes specific operations between services, enabling functions beyond standard capabilities without using standard applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If extension services are provided without using standard applications, then customizability and additional functionalities are improved, but service management complexity and coordination difficulty increase
Solution Approach 1:
The patent introduces an extension service management unit as an intermediary component that coordinates between multiple extension services and the extension application. This management unit handles service registration, state monitoring, and inter-service communication, thereby enabling customizability while managing the complexity of coordinating multiple extension services without requiring the extension application to directly manage each service individually.
2Adaptability or versatility
If multiple extension services are coordinated through notification mechanisms, then service integration and collaboration are improved, but communication overhead and response time increase
Solution Approach 1:
The patent implements a feedback mechanism where the extension service management unit monitors the states of extension services and automatically notifies relevant services of state changes. This feedback loop enables services to respond to changes in other services' states, improving integration and collaboration while maintaining efficient communication through automated rather than manual notification processes.

AI summary
An image forming device includes a data collection service and a mail transmission service as extension services for providing a function other than a standard function of the image forming device to an extension application, and an extension service management unit for managing the data collection service and the mail transmission service. When the state of one of a plurality of extension services changes, a service activation control unit of the extension service management unit notifies the other of the plurality of extension services of the change. When the extension service is notified of the change in the state of the other extension service from the service activation control unit, the extension service executes a specific operation.
