Solution Overview

Problem

Digital multi-function peripherals (MFPs) face usability issues due to limited input and display capabilities, requiring users to manually set both image forming and network conditions, which complicates operations and compromises security by allowing unauthorized access.

Innovation Solution

A multi-function input/output device that uses an optically readable device control setting medium to automatically set image forming and network conditions, incorporating a scanner to read two-dimensional codes containing authentication and setup information, thereby simplifying user interactions and enhancing security by restricting access to authorized users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of device control setting items is increased to provide multiple functions, then the functionality and versatility of the digital copier is improved, but the ease of operation deteriorates due to the limited size of liquid crystal display and hard keys

Engineering Contradiction:
ImprovefunctionalityVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The invention uses a barcode (optical copy) to represent device control setting items, allowing multiple setting items to be displayed in a compact format that overcomes the physical limitations of the liquid crystal display and hard keys

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The invention transitions from a two-dimensional display layout to a barcode encoding system that packs multiple setting items into a compact optical pattern, effectively adding a new dimension for information representation

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the number of displaying layers is increased to accommodate more setting items, then the functionality is improved, but the ease of use deteriorates due to complex navigation through multiple screens

Engineering Contradiction:
ImprovefunctionalityVSAvoidease of use
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Instead of using multiple display layers, the invention creates a single-layer barcode that encodes all necessary setting information, eliminating the need for users to navigate through multiple screens

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The barcode segments multiple setting items into discrete encoded units that can be individually identified and processed by the scanner, allowing complex information to be conveyed in a single visual element

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If manual input operations are required for both image forming and network settings, then the adaptability is improved, but the productivity deteriorates due to the time-consuming setup process

Engineering Contradiction:
ImproveadaptabilityVSAvoidproductivity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The invention pre-encodes all device control setting items into a barcode, so that when the barcode is scanned, the settings are automatically applied without requiring users to manually input each setting during operation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system performs automatic setup by scanning the barcode and self-configuring the device settings, eliminating the need for manual user input and significantly reducing setup time

Inventive Principle:
Principle #25Self-service

4Ease of operation

If the device is made accessible to all users, then the ease of operation is improved, but the security deteriorates by allowing unauthorized access

Engineering Contradiction:
ImproveaccessibilityVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The invention applies different quality levels to different parts of the barcode system: the barcode itself provides open access for authorized users, while embedded authentication information provides restricted access control for sensitive operations

Inventive Principle:
Principle #3Local quality

AI summary

In a multi-function input/output device, an optical reading unit optically reads an optically readable code from a device control setting medium on which device control setting information, including use authentication information and unit-control-setting information for a document input control setting unit, a document-data-processing control setting unit, and a document-data-output control setting unit, is recorded. The device control setting information including the use authentication information is recognized from the code read by the optical reading unit. A user authentication unit authenticates the user by using a use authentication code of the use authentication information. A setting processing unit sets the unit-control-setting information based on a recognition result of the device control setting information and the use authentication information.
