Solution Overview

Problem

Users face inconvenience when trying to control smart home devices without a terminal device, as they need to physically move to the device or the terminal to issue control commands.

Innovation Solution

A device control method utilizing a target voice module equipped with audio processing capabilities, which communicates with servers to convert voice commands into control instructions and control smart home devices remotely.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users control smart home devices using a terminal device, then control functionality is achieved, but users need to physically move to the device or terminal to issue control commands

Engineering Contradiction:

ImproveConvenience of device controlVSAvoidTime for physical movement

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the mechanical approach of physically moving to the device or terminal with an acoustic field-based voice control system. The voice module captures sound waves acoustically and transmits control commands through network communication, eliminating the need for physical displacement of the user.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The voice module acts as an intermediary between the user and the smart home devices. It captures voice commands, converts them to control instructions through server processing, and transmits them to the target devices, serving as a mediating component that enables remote control without direct user-device interaction.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Speed

If voice control is implemented locally without server communication, then response speed is faster, but control functionality and reliability are limited

Engineering Contradiction:

ImproveVoice control response speedVSAvoidControl instruction accuracy

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The system performs preliminary voice capture and preprocessing locally through the voice module, enabling rapid initial response. The captured voice data is then transmitted to servers for comprehensive processing, combining local speed advantages with server-side reliability for accurate control instruction generation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The control system is segmented into local and remote components. The voice module handles local voice capture and initial processing for speed, while the server handles complex voice recognition and control instruction generation for reliability. This segmentation allows each component to optimize for its specific function.

Inventive Principle:

Principle #1Segmentation
