Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing image processing devices lack secure and efficient communication capabilities when connecting to virtual private networks (VPNs), particularly in multi-function devices like printers and scanners, which hinders secure data transmission and printing/scanning operations across networks.

Innovation Solution

An image processing device is designed with an image processing unit, a user interface unit, and a VPN processing unit, allowing secure VPN connections through authentication information obtained via the user interface, enabling secure communication and operation within a VPN environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If image processing devices connect to VPN using stored authentication information, then secure communication is achieved, but device complexity increases due to additional VPN processing requirements

Engineering Contradiction:

Improvesecure communicationVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The image processing device integrates VPN processing capabilities into its existing communication functions, allowing the device to perform both image processing and secure VPN communication through unified authentication mechanisms. The device can function as both a traditional imaging device and a VPN client without requiring separate dedicated hardware

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The image processing device autonomously performs VPN authentication and connection management using its own built-in authentication information storage and processing capabilities, rather than relying entirely on external servers or manual configuration. The device automatically establishes secure connections when needed

Inventive Principle:

Principle #25Self-service

2Ease of operation

If authentication information is obtained through UI unit, then ease of operation is improved, but loss of time increases due to manual input requirements

Engineering Contradiction:

Improveease of operationVSAvoidloss of time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

Authentication information is pre-configured and stored in the image processing device during initial setup or device provisioning. This preliminary configuration eliminates the need for repeated manual authentication inputs during normal operation, reducing time loss while maintaining ease of operation for subsequent connections

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device stores copies of authentication information (such as certificates, keys, or credentials) in its memory system, allowing rapid retrieval and reuse without requiring repeated manual entry. This copying mechanism enables quick authentication while maintaining security through encrypted storage

Inventive Principle:

Principle #26Copying
