Solution Overview

Problem

Configuring multiple network devices, especially in geographically diverse and remote locations, is challenging due to the need for skilled administrators, high costs, and security concerns when pre-configuring devices with sensitive information at the point of manufacture.

Innovation Solution

A system where network devices, such as wireless switches, can automatically request and receive configuration information from a management server over a network, allowing untrained personnel to initiate the process by simply connecting the device and applying power, enabling secure and efficient configuration of multiple devices without on-site technical expertise.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If network devices are pre-configured with required configuration information at the place of manufacture, then configuration speed is improved, but security is worsened since configuration information including security information would be exposed at the point of manufacture

Engineering Contradiction:
Improveconfiguration speedVSAvoidsecurity exposure
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by pre-configuring devices with minimal bootstrap information (device identifier and configuration server address) at manufacture, then completes the full configuration automatically after deployment through communication with the configuration server, thus balancing early preparation with security

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention extracts sensitive configuration information from the device manufacturing process and transfers it to a secure configuration server, where it remains protected until automatically deployed to specific devices through secure communication channels

Inventive Principle:
Principle #2Taking out (Extraction)

2Manufacturing precision

If skilled network administrators manually configure each network device, then configuration accuracy is improved, but labor cost and time consumption are worsened

Engineering Contradiction:
Improveconfiguration accuracyVSAvoidtime consumption
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system enables self-service by allowing network devices to automatically request and receive their own configuration information from the configuration server using their device identifiers, eliminating the need for manual administrator intervention while maintaining accuracy through server-side validation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The configuration server acts as an intermediary between device manufacturing and deployment, automatically matching devices with their correct configuration information based on device identifiers, thus replacing manual administrator work with automated server-side processing

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If configuration information is communicated over unsecure networks, then ease of operation is improved, but network security is worsened exposing the network to compromise and vulnerability to outside attack

Engineering Contradiction:
Improveease of configurationVSAvoidnetwork security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system changes the security parameter of communication by implementing encryption and authentication protocols between devices and the configuration server, allowing secure configuration updates even when communicating over unsecure networks like the Internet

Inventive Principle:
Principle #35Parameter changes
