Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing information processing systems for image forming devices require users to input both an initial password and an update password during the initial setup, which can be inconvenient and time-consuming.

Innovation Solution

A control device configured to acquire setup information related to the initial setup of an image processing device and display a password setting screen that only requires inputting an update password, eliminating the need to input the initial password.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system requires users to input both initial password and update password during initial setup, then security is ensured through password verification, but user convenience deteriorates due to increased input requirements

Engineering Contradiction:

Improvepassword securityVSAvoidsetup convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The initial password is prestored in the image processing device before the user arrives. This preliminary action eliminates the need for users to input the initial password during setup, as the system already has it stored and ready for verification against the update password.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system performs self-verification by comparing the update password against the prestored initial password automatically. This self-service mechanism eliminates the need for manual verification steps, reducing user input requirements while maintaining security through automated password comparison.

Inventive Principle:

Principle #25Self-service

2Reliability

If the system requires input of both initial password and update password, then password update reliability is improved, but setup time increases

Engineering Contradiction:

Improvepassword update reliabilityVSAvoidsetup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The initial password is prestored in the device before user interaction begins. This preliminary preparation eliminates the time required for users to retrieve or remember the initial password, reducing overall setup time while maintaining password update reliability through automated verification.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system extracts and removes the initial password input step from the user interaction sequence. By taking out this step and using the prestored password automatically, the system reduces setup time while maintaining security through the extracted verification mechanism that compares update password against the stored initial password.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A control device may acquire first setup information related to a progress of an initial setup of a specific image processing device, and in a case where the acquired first setup information includes first information, display a first password setting screen on a display, in which the first password setting screen does not include a first password input area for inputting an initial password but includes a second password input area for inputting an update password, the initial password being necessary to access the specific image processing device and being prestored in the specific image processing device, and the update password being a password to replace the initial password necessary to access the specific image processing device.
