Image Forming Apparatus Virtual Storage Area for User Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses face challenges in efficiently managing personal setting values due to limited storage capacity and the need for users to repeatedly configure settings, leading to user frustration and potential storage overflow.
Innovation Solution
The implementation of a virtual storage area within the image forming apparatus allows for temporary storage of personal setting values when the storage capacity is reached, enabling seamless user experience by automatically switching to the virtual storage area during login and deleting data when the user logs out, thus preventing storage overflow and user confusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If personal setting values are stored for each user, then user convenience is improved, but storage capacity is consumed
Solution Approach 1:
The patent divides the storage system into two distinct segments: a standard storage area for permanent personal setting values and a virtual storage area for temporary settings. This segmentation allows the system to maintain user convenience by storing settings while managing storage capacity through clear differentiation between persistent and temporary data.
Solution Approach 2:
The virtual storage area functions as a disposable storage mechanism where temporary setting values are stored without consuming permanent storage capacity. These virtual settings are automatically discarded when no longer needed, analogous to using disposable objects that serve their purpose and are then discarded without long-term resource consumption.
2Device complexity
If storage capacity is limited with quota function, then storage management is improved, but user access is restricted when quota is exceeded
Solution Approach 1:
The virtual storage area acts as an intermediary between the quota limitation system and user access needs. When users exceed their storage quota, the virtual storage area provides an intermediate solution that allows continued access and setting functionality without violating the storage management constraints, thus mediating between storage control and user convenience.
3Device complexity
If automatic clear function is used, then storage management is improved, but user settings are lost after predetermined time
Solution Approach 1:
The patent applies different quality characteristics to different storage areas: the standard storage area provides permanent retention for personal setting values, while the virtual storage area provides temporary retention. This local differentiation of storage qualities allows the system to maintain settings where needed while automatically clearing temporary virtual settings, preventing information loss in permanent storage while enabling storage management through temporary area clearance.

AI summary
An image forming apparatus includes a storage unit that stores a personal setting value of a user, a reception unit that receives a login of the user, and a control unit that that determines whether the personal setting value of the user whose login is received can be stored in the storage unit, and in a case where it is determined that the personal setting value cannot be stored and registration of the personal setting value is instructed by the user whose login is received, performs control so as to store the personal setting value of which the registration is instructed in a virtual storage area prepared for temporary storage.
