Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems face challenges in efficiently managing and resetting the default user password for multifunction peripherals, particularly when users forget or need to change the password, leading to restricted operations and difficulties in connecting these devices to management systems.

Innovation Solution

An electronic device and device management system are designed to include a communication device, storage device, and control device, which allow for resetting the default user password by rewriting it to a default value upon request, and a device management system that can transmit such requests across networks, utilizing computer-readable media to execute device control and management programs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the default user password is changed or forgotten, then security is improved, but the ease of operation deteriorates because users cannot log in and operations are restricted

Engineering Contradiction:

Improvepassword securityVSAvoidlogin accessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device enables self-service password resetting by allowing the default user to reset their own password through a simple operation on the device interface, eliminating the need for external intervention while maintaining security through authentication mechanisms

Inventive Principle:

Principle #25Self-service

2Ease of operation

If the password is reset to default value, then ease of operation is improved, but security deteriorates because the default password is publicly known

Engineering Contradiction:

Improvepassword recoveryVSAvoidpassword security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary authentication verification before allowing password resetting, checking that the user is indeed the default user through device-internal verification mechanisms, thus enabling safe password recovery without compromising security

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device provides feedback mechanisms to confirm successful password resetting and guides users through the process, ensuring that the password is properly updated while maintaining security through controlled access and verification steps

Inventive Principle:

Principle #23Feedback

3Reliability

If external intervention is required to reset password, then security is improved, but productivity deteriorates due to service person visits or support center contact

Engineering Contradiction:

Improvepassword securityVSAvoidpassword resetting efficiency

Core Design Contradiction:

AI summary

An electronic device includes a communication device, a storage device, and a control device that acts as a device controller. The communication device communicates with an external device. The storage device stores therein a log-in password and a default value of a default user. The device controller resets, upon receipt of a request to reset the log-in password via the communication device, the log-in password of the default user, by rewriting the log-in password to the default value.
