Solution Overview

Problem

The process of binding an intelligent terminal to a user account is complex and time-consuming, requiring multiple configuration steps.

Innovation Solution

A device binding method that involves generating and matching signal fingerprints at specific positions to automatically bind an intelligent terminal to a user account, using a server to determine the correspondence between the terminal's signal fingerprint and the user's account based on collected Wi-Fi or Bluetooth signals, and configuring the terminal accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a user manually binds a device to a terminal device, then the binding process can be customized, but the operation becomes complex and time-consuming

Engineering Contradiction:
Improvebinding operation simplicityVSAvoidbinding time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent implements automatic binding where the terminal device autonomously sends binding requests to the device without requiring manual user intervention. The system automatically receives binding responses and establishes the binding relationship, allowing the device to serve itself rather than requiring complex manual operations from the user.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent pre-configures binding parameters and establishes binding relationships in advance through automatic mechanisms. The terminal device proactively initiates binding requests and pre-establishes the necessary communication protocols, so that when actual usage occurs, the binding is already in place and no time-consuming manual configuration is needed.

Inventive Principle:
Principle #10Preliminary action

2Loss of time

If automatic binding is implemented, then binding time is reduced, but the system complexity increases

Engineering Contradiction:
Improvebinding timeVSAvoidbinding mechanism complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent employs a universal binding mechanism that can handle multiple types of devices and terminal devices through a standardized binding protocol. The same automatic binding process works for various device types (worn devices, smart home devices, etc.), eliminating the need for device-specific complex binding mechanisms while maintaining simplicity across the board.

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

Solution Approach 2:

The patent introduces a binding response message as an intermediary element that carries binding parameters from the device to the terminal device. This intermediary structure simplifies the overall system by providing a standardized interface for binding information exchange, making the automatic binding process manageable despite the increased automation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If binding parameters are not considered in automatic binding, then the process is simpler, but the binding may not meet user needs

Engineering Contradiction:
Improvebinding process complexityVSAvoidbinding adaptability to user needs
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent incorporates binding parameters as changeable elements that can be adjusted based on user needs. The binding response message includes parameters such as binding time, validity period, and other configurable settings that allow the automatic binding process to adapt to different user requirements while maintaining overall simplicity through standardized parameter handling.

Inventive Principle:
Principle #35Parameter changes

AI summary

This application provides a device binding method. The method includes: A user terminal collects a signal at a collection position, generates a first signal fingerprint, and sends the first signal fingerprint and a corresponding first account to a server. An intelligent terminal collects a signal at a set position, generates a second signal fingerprint, and sends the second signal fingerprint and a corresponding device identifier of the intelligent terminal to the server. The server determines that the second signal fingerprint matches the first signal fingerprint, to determine that the second signal fingerprint is corresponding to the first account. The server binds the intelligent terminal to the first account based on a correspondence between the second signal fingerprint and the device identifier of the intelligent terminal. In this application, efficiency and accuracy of binding the intelligent terminal to the first account are improved.
