Image Forming Device Screen Transition for External Service Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming devices lack user-friendly interfaces for accessing external services, leading to poor usability during authentication processing.
Innovation Solution
The device includes a first and second setting screen, with controllers switching from a device internal mode to an Internet connection mode upon user instruction, allowing seamless transition and improved user interface for authentication with external services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the image forming device uses a unified setting screen for both internal functions and external service cooperation, then the device structure is simple, but the usability for authentication processing deteriorates
Solution Approach 1:
The setting screen is segmented into two distinct modes: a first setting screen for internal device functions and a second setting screen for external service authentication. This segmentation allows each screen to be optimized for its specific purpose, improving usability without significantly increasing overall system complexity.
Solution Approach 2:
The controller dynamically switches between the first setting screen and the second setting screen based on the received instruction type. This dynamic switching capability allows the device to adapt its interface to the current operational context, providing appropriate usability for each mode while maintaining a unified underlying system structure.
2Ease of operation
If the image forming device provides a dedicated interface for external service authentication, then the usability for authentication processing is improved, but the device complexity increases
Solution Approach 1:
The controller serves multiple functions by managing both the first setting screen for internal operations and the second setting screen for external authentication. This multi-functionality allows the device to provide dedicated authentication interface capabilities without requiring separate hardware components, thereby improving usability while controlling complexity growth.
3Productivity
If the controller switches control modes between internal function and external service cooperation, then the authentication processing efficiency is improved, but the control system complexity increases
Solution Approach 1:
The controller implements dynamic mode switching between first control mode (internal functions) and second control mode (external service authentication). This dynamic control mechanism enables efficient authentication processing by dedicating appropriate control logic to each mode, while the switching framework remains integrated within the existing controller architecture, limiting the increase in overall system complexity.

AI summary
An image forming device includes a display that displays a first setting screen and a second setting screen, and one or more controllers. The first setting screen receives a setting related to an internal function of the image forming device and the second setting screen receives a setting related to cooperation with an external service. In a case of receiving an instruction to cooperate with the external service via the first setting screen, the one or more controllers switch a control mode of the device from a first control mode related to the internal function of the image forming device to a second control mode related to the cooperation with the external service, and cause a display screen to transition from the first setting screen to the second setting screen.
