Solution Overview

Problem

The installation of network repeaters is complex for users without technical knowledge, particularly in extending wireless networks at home, due to the need for manual configuration of wireless network details and security settings, and existing solutions like WPS have security flaws.

Innovation Solution

A method for connecting a network repeater to access equipment using authentication with identification information, including a public key and private key pair, automated device detection, and voice-based user interaction to simplify the installation process while ensuring security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual configuration of wireless network details and security settings is required, then security is ensured, but installation complexity increases for non-technical users

Engineering Contradiction:
ImprovesecurityVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies preliminary action by pre-configuring the repeater with identification information (including cryptographic keys) before deployment. During installation, the repeater automatically transmits this identification information to the access point, which retrieves stored configuration parameters using this information. This eliminates the need for users to manually configure security settings during installation, while maintaining security through pre-established cryptographic authentication.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If WPS technology is used for simple pairing, then ease of operation is improved, but security flaws are introduced

Engineering Contradiction:
Improvepairing simplicityVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces an intermediary mechanism where the access point serves as a secure mediator between the repeater and the network configuration. The repeater transmits only identification information (not full credentials), and the access point uses this to retrieve pre-stored configuration parameters from its memory. This intermediary approach simplifies user interaction while maintaining security through the access point's role as a trusted mediator that controls parameter distribution.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the security-critical configuration parameters from the repeater and stores them securely in the access point's memory during manufacturing or initial setup. The repeater only carries identification information, which is insufficient for unauthorized network access. This extraction separates the authentication function (held by repeater) from the configuration distribution function (held by access point), improving both simplicity and security.

Inventive Principle:
Principle #2Taking out (Extraction)

3Extent of automation

If identification information is transmitted beforehand to access equipment, then automated authentication is enabled, but device complexity increases

Engineering Contradiction:
Improveautomated authenticationVSAvoidauthentication mechanism complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the access point to perform multiple functions: it acts as a wireless access point, stores configuration parameters in its memory, receives and processes identification information from repeaters, retrieves corresponding parameters using this information, and transmits them automatically. This multi-functionality consolidates what would otherwise require separate systems into a single device, reducing overall system complexity while enabling automated authentication.

Inventive Principle:
Principle #6Universality (Multi-functionality)
