Image Forming Apparatus Personal Setting Synchronization Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses lack flexibility in managing personal settings and password information, as they cannot collectively control synchronization with a server based on firmware version, leading to security concerns and user experience issues.
Innovation Solution
An image forming apparatus with a storing unit, synchronization management unit, and export unit that allows applications to freely select and collectively change synchronization of personal settings with a server, using a synchronous control flag associated with each setting to manage synchronization according to the firmware version.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If personal settings are synchronized with a server, then user experience is improved through centralized management, but security is worsened due to centralized storage of confidential information
Solution Approach 1:
The patent segments the personal settings into different categories: general settings that can be synchronized with the server, and confidential information (passwords, authentication data) that remains local. The synchronous control information allows each setting to be independently controlled, enabling selective synchronization that balances user experience with security requirements.
Solution Approach 2:
Different storage locations are assigned based on the nature of the data: centralized server storage for non-sensitive settings and local device storage for sensitive information. This local quality approach allows the system to optimize for convenience where appropriate while maintaining security where necessary.
2Adaptability or versatility
If synchronization is controlled individually for each setting, then flexibility is improved, but device complexity increases
Solution Approach 1:
The synchronous control information serves multiple functions: it acts as a flag to identify which settings should be synchronized, as export information when distributing personal settings to other devices, and as a control mechanism for firmware version-based synchronization policies. This multi-functionality reduces the need for separate control mechanisms.
Solution Approach 2:
The system automatically manages synchronization based on the synchronous control information and firmware version, eliminating the need for manual configuration of each setting. The export unit also automatically includes synchronous control information when distributing settings, reducing administrative overhead.
3Adaptability or versatility
If firmware updates change synchronization behavior, then adaptability is improved, but reliability worsens due to potential inconsistency across devices
Solution Approach 1:
The synchronous control information is exported along with personal settings when distributing them to other devices. This preliminary action ensures that the receiving device has the necessary control information to maintain consistent synchronization behavior, even across firmware updates and device migrations.
Solution Approach 2:
The system uses firmware version information as feedback to determine synchronization behavior. When firmware is updated, the system can detect the version change and adjust synchronization settings accordingly, maintaining consistency across the device fleet while adapting to new requirements.
Data Source
AI summary
Personal settings for each user and each application are stored in personal setting holding units 311 and 310. When a personal setting is to be exported, synchronous control information indicating whether or not synchronization is to be performed for each personal setting is exported. In the case where the firmware version of an apparatus that is to import the information indicates synchronization of the personal setting, the personal setting is rewritten in accordance with the synchronous control information.
