Electronic Equipment Setting Modification via Email Permission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printer systems face complications due to posterior reports of setting modifications, which can lead to security issues and unnecessary re-modifications, as administrators may not be able to permit or reject these changes in a timely or clear manner.
Innovation Solution
The electronic equipment includes an instruction receiving unit for setting modifications and an electronic mail sending unit that sends access information for a web page permission, allowing administrators to explicitly permit or reject setting changes, with the equipment maintaining current settings until permission is granted or denied, and deleting unauthorized modification requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the printer performs setting modification and sends a posterior completion notification to the administrator, then the administrator is informed of the modification, but the administrator cannot permit or reject the modification in advance, leading to security issues and complications
Solution Approach 1:
The system sends an electronic mail to the administrator before the setting modification is executed, requesting permission in advance. The modification is postponed until the administrator responds, allowing pre-approval rather than post-notification. This resolves the contradiction by enabling security approval while avoiding the complication of unauthorized modifications followed by notifications.
2Loss of information
If the administrator receives a posterior report of setting modification, then the administrator is notified of the change, but the administrator must make the user modify the setting again if permission is not granted, causing unnecessary re-modification
Solution Approach 1:
The system requests administrator permission before executing setting modifications by sending an electronic mail with the modification details. The modification is only executed after the administrator grants permission or the permission request expires. This prevents unauthorized modifications, ensuring that no setting information is lost and eliminating the need for time-consuming re-modifications.
Solution Approach 2:
The system implements a feedback loop where the administrator's response to the permission request directly controls whether the modification is executed. The electronic mail system provides feedback from the administrator to the printer, allowing the administrator to approve or reject modifications before they take effect. This feedback mechanism prevents loss of setting information and eliminates unnecessary re-modification time.
3Reliability
If the electronic equipment sends an electronic mail for permission before setting modification, then the administrator can permit or reject the modification, but the process requires additional communication steps
Solution Approach 1:
The electronic mail system serves as an intermediary between the user who requests modification and the administrator who grants permission. The mail system transmits the modification request and receives the approval response, mediating the authorization process. This intermediary approach ensures reliable authorized modification while managing the additional communication steps through an automated, standardized process rather than manual intervention.

AI summary
There is provided electronic equipment including: an instruction receiving unit that receives an instruction of a setting modification regarding the electronic equipment; and an electronic mail sending unit that sends an electronic mail including access information on a web page for permission of the setting modification by the modification instruction to a mail address corresponding to a predetermined administrator in a case of receiving the modification instruction. The electronic equipment further includes: a setting modification unit that modifies the setting according to the modification instruction based on the access to the web page.
