Solution Overview

Problem

Users face difficulties in inputting correct authentication information for multiple destinations in image transmission, leading to transmission failures due to different authentication requirements for various servers, such as SMB and FTP servers.

Innovation Solution

An image transmission apparatus with a multi-address transmission function and each-time authentication capability, which allows users to pre-register authentication information for destinations and switch between automatic and manual authentication modes, reducing errors by limiting the number of destinations for each authentication mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users manually input authentication information for each destination, then the system can support multiple different authentication mechanisms (SMB, FTP), but the complexity of operation increases and error rate increases

Engineering Contradiction:
Improveauthentication mechanism compatibilityVSAvoidauthentication input complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs preliminary action by automatically obtaining authentication information from an authentication server before the actual image transmission occurs. The control unit retrieves usernames and passwords for multiple destinations in advance, stores them temporarily, and makes them available for subsequent transmissions without requiring users to manually input credentials each time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

An authentication server acts as an intermediary between the image transmission apparatus and multiple destination servers (SMB, FTP, etc.). Instead of users directly managing credentials for each destination, the authentication server mediates by providing centralized authentication information retrieval, eliminating the need for users to handle multiple different authentication mechanisms manually.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the system prompts for authentication information before each transmission, then security is maintained, but transmission efficiency decreases due to repeated user operations

Engineering Contradiction:
Improveauthentication securityVSAvoidtransmission efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system maintains continuity of useful action by automatically retrieving and storing authentication information for multiple destinations, then using this pre-obtained information for subsequent transmissions. This eliminates the need to repeatedly prompt users for authentication before each transmission, maintaining both security through authenticated access and efficiency through automated credential management.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system performs self-service by automatically obtaining, storing, and managing its own authentication information without requiring continuous user intervention. The control unit independently retrieves credentials from the authentication server and manages the transmission process using stored authentication data, freeing users from repetitive manual authentication tasks while maintaining secure access.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If users must input correct authentication information for all destinations, then transmission accuracy improves, but the time required for operation increases

Engineering Contradiction:
Improveauthentication accuracyVSAvoidauthentication input time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system performs preliminary action by automatically obtaining and verifying authentication information for all destinations before transmission begins. The control unit retrieves credentials in advance, ensuring accuracy through automated retrieval rather than manual input, and stores them for immediate use during transmission operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system replaces the mechanical process of manual authentication input with an automated information processing mechanism. Instead of users physically typing credentials, the control unit automatically retrieves authentication information from the authentication server using electronic communication, eliminating manual input errors and reducing the time required for authentication.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
