Solution Overview

Problem

In conventional image processing apparatuses, there is no consideration for user authority when displaying notification information, leading to the risk that general users may delete important notification information intended for administrators.

Innovation Solution

An image processing apparatus is designed with a detector to identify events, a display to show notification information, and a controller that restricts operation authority over the notification information to specific users, ensuring that administrators are properly notified of critical events.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If notification information is made accessible to all users, then ease of operation is improved, but reliability deteriorates due to risk of deletion by unauthorized users

Engineering Contradiction:
Improveaccessibility of notification informationVSAvoidcertainty of administrator notification
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies local quality by differentiating access rights for different notification types. Administrator notifications are restricted to administrator-only access, while general notifications are accessible to all users. This is implemented through the notification management table that stores authentication requirement flags for each notification, allowing the system to provide differentiated access control based on the specific notification's security requirements.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If operation authority is unrestricted, then ease of operation is improved, but loss of information increases due to potential deletion of critical notifications

Engineering Contradiction:
Improveoperability of notification informationVSAvoiddeletion of administrator notifications
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent implements preliminary anti-action by pre-configuring authentication requirements in the notification management table before notifications are displayed. The system proactively prevents unauthorized deletion by requiring administrator authentication for critical notifications before allowing any operation that would modify or delete them. This preventive measure is embedded in the notification display control that checks authentication status before permitting operations.

Inventive Principle:
Principle #9Preliminary anti-action

3Reliability

If operation authority is restricted to specific users, then reliability is improved, but ease of operation deteriorates due to additional authentication requirements

Engineering Contradiction:
Improvecertainty of authorized accessVSAvoidaccess convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies partial action by implementing authentication requirements only for specific notification types that require it, rather than universally for all notifications. The notification management table stores authentication requirement flags that allow the system to apply authentication checks selectively - administrator notifications require authentication while general notifications do not. This partial application of authentication maintains reliability for critical information while preserving ease of operation for non-critical information.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

An image processing apparatus according to an embodiment includes: a detector which detects an occurrence of an event; a display which displays notification information regarding the occurred event; and a controller which restricts operation authority over the notification information displayed on the display to a specific user when the notification information corresponds to a notification for the specific user, and makes the operation authority over the notification information di splayed on the display unrestricted when the notification information does not correspond to a notification for the specific user.
