Solution Overview

Problem

The existing Wi-Fi Protected Setup (WPS) configuration process for wireless terminals is overly complex, requiring an 8-digit PIN entry and multiple message exchanges, which complicates the setup process for users.

Innovation Solution

A method where a registration apparatus scans a multi-dimensional code on a wireless terminal to acquire a configuration password, encrypts configuration information, and sends it to the terminal through a wireless access device, allowing the terminal to decrypt and access the network, reducing interaction processes and simplifying the configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the traditional WPS PIN mode is used for wireless terminal configuration, then security authentication is achieved, but the configuration process becomes complex requiring manual PIN entry and multiple message exchanges

Engineering Contradiction:

Improvesecurity authenticationVSAvoidconfiguration process complexity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the manual mechanical input of PIN codes with automatic optical recognition through multi-dimensional code scanning. The registration apparatus automatically captures and processes the multi-dimensional code containing configuration credentials, eliminating the need for manual PIN entry and reducing configuration steps while maintaining security through encrypted credential transmission.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a multi-dimensional code as an intermediary carrier that contains encrypted configuration credentials. This code serves as a mediator between the wireless terminal and registration apparatus, allowing automatic credential transfer without direct interaction or manual input, thus simplifying the configuration process while preserving security.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If manual PIN entry and multiple message exchanges are required, then secure configuration is achieved, but the configuration time increases

Engineering Contradiction:

Improvesecure configurationVSAvoidconfiguration time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary action by pre-encoding configuration credentials into a multi-dimensional code that can be automatically scanned and recognized. This preparation work is done in advance, allowing the registration apparatus to quickly retrieve and process configuration information without requiring time-consuming manual entry or multiple interaction rounds during the actual configuration process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces time-consuming manual PIN entry and iterative message exchanges with rapid automatic optical scanning and recognition. The multi-dimensional code scanning technology enables the registration apparatus to instantly capture configuration credentials, dramatically reducing configuration time while maintaining security through encrypted credential transmission.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If the configuration process requires multiple interaction steps, then authentication security is maintained, but the user operation complexity increases

Engineering Contradiction:

Improveauthentication securityVSAvoidinteraction process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the configuration credentials from the complex multi-step interaction process and embeds them directly into a multi-dimensional code. This extraction allows the credentials to be transferred in a single scanning operation rather than through multiple message exchanges, simplifying the interaction process while maintaining authentication security through encrypted credential transmission.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses a multi-dimensional code as an intermediary that encapsulates all necessary configuration credentials. This single intermediary object replaces multiple interaction steps, allowing the registration apparatus to obtain all required information in one scanning operation, thereby reducing interaction complexity while preserving security through the encrypted content of the code.

Inventive Principle:

Principle #24Intermediary (Mediator)
