Server-Mediated Home Appliance Voice Control Across Rooms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in controlling home appliances with voice commands from a distance, particularly with appliances installed in hard-to-reach locations, as existing voice control systems require physical proximity.
Innovation Solution
A home appliance control method that involves a server receiving voice messages, determining appliance information, generating control instructions, and sending them to the corresponding appliances, allowing for remote voice control by binding appliances to the same account or group and using notification mechanisms to facilitate instruction acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If voice control requires physical proximity to the home appliance, then the voice recognition accuracy is improved, but the user convenience and control distance are worsened
Solution Approach 1:
The patent introduces a server as an intermediary between the user's voice input and the target home appliance. The server receives voice messages from any home appliance in the network, performs centralized voice recognition, and distributes control instructions to the appropriate appliance. This mediator approach allows users to issue voice commands from any location in the home without needing to be physically close to the target appliance, thereby improving user convenience while maintaining control accuracy through centralized processing.
2Adaptability or versatility
If each home appliance is equipped with complex voice recognition systems, then the voice control capability is improved, but the manufacturing cost and device complexity are worsened
Solution Approach 1:
The patent implements a universal voice recognition system where the server performs voice recognition for all home appliances in the network. Instead of each appliance having its own voice recognition module, the server serves as a multi-functional platform that handles voice processing for diverse appliances (air conditioners, televisions, lights, etc.). This universal approach reduces device complexity and manufacturing costs while maintaining comprehensive voice control capability across all appliances through centralized intelligence.
3Ease of operation
If voice control is implemented in hard-to-reach locations, then the user convenience is improved, but the voice signal quality and recognition accuracy are worsened
Solution Approach 1:
The server acts as an intermediary that receives voice messages transmitted through the home appliance network rather than requiring direct acoustic capture from the user. This allows users to issue voice commands from any location in the home, including hard-to-reach areas, as the voice signal is transmitted electronically through the network infrastructure to the server for processing, eliminating the relationship between physical distance and signal quality.

AI summary
A home appliance control method includes receiving, by a server, a voice message sent from a first home appliance, determining appliance information and control information of a second home appliance according to the voice message, generating a control instruction corresponding to the appliance information according to the control information, storing the control instruction, upon receiving a control instruction acquisition request sent from the second home appliance, acquiring the appliance information corresponding to the second home appliance, and sending the stored control instruction corresponding to the appliance information to the second home appliance to configure the second home appliance to execute the control instruction.
