Image Processing Apparatus Resume Auto-Clear Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multifunction image processing apparatuses face user inconvenience due to the conflict between resume and auto-clear functions, where users struggle to balance convenience and security in maintaining and resetting settings.
Innovation Solution
An image processing apparatus comprising a resume unit to reproduce settings, an auto-clear unit to clear settings, and a switching unit to toggle between these functions, allowing exclusive enabling of both resume and auto-clear functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the resume function is enabled to automatically reproduce previous settings, then user convenience is improved, but security risks increase as current users may inadvertently use previous users' settings
Solution Approach 1:
The patent applies local quality by differentiating the treatment of settings based on user authentication status. Registered users experience the resume function that automatically reproduces their previous settings, while unregistered or current users see initialized settings. This localized approach allows the system to provide convenience to authorized users without exposing security risks to unauthorized users.
2Object-affected harmful factors
If the auto-clear function is enabled to initialize settings after a period of inactivity, then security is improved, but user convenience deteriorates as users must re-enter settings
Solution Approach 1:
The patent applies dynamics by making the setting initialization behavior conditional rather than static. The system dynamically adjusts whether to initialize settings based on real-time user authentication status. When a user is authenticated, the system maintains previous settings; when unauthenticated or after timeout, the system initializes settings. This dynamic behavior allows the system to balance security and convenience based on current operational context.
3Adaptability or versatility
If both resume and auto-clear functions are enabled simultaneously, then functional completeness is improved, but system complexity increases due to conflicting operations
Solution Approach 1:
The patent resolves the conflict between resume and auto-clear functions by applying local quality - each function operates in its own designated context. The resume function operates locally for authenticated users, while the auto-clear function operates locally for unauthenticated users or after timeout periods. This contextual separation eliminates operational conflicts while maintaining both functions' benefits.
Solution Approach 2:
The system dynamically determines which function to execute based on real-time conditions. The control unit monitors user authentication status and actively selects either the resume function or the auto-clear function, preventing their simultaneous conflicting execution. This dynamic control mechanism simplifies system operation while maintaining functional completeness.

AI summary
An object of the present invention is to exclusively enable both a resume function and an auto-clear function. To achieve the object, there are provided a resume unit configured to reproduce setting based on stored setting information, an auto-clear unit configured to clear the setting information, and a switching unit configured to switch from an operation of enabling either one of the resume unit and the auto-clear unit to an operation of enabling the other of the resume unit and the auto-clear unit.
