Multi-Device Voice Control With Master Device Target Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional home appliances with voice recognition systems face issues such as operation confusion, the need for users to memorize different start commands for each device, inability to control devices without voice input units, and reliance on server intervention for prioritizing voice commands.
Innovation Solution
A method for controlling multiple electronic devices that allows operation using natural language voice commands or a single feature point, without requiring users to memorize start commands for each device. This method eliminates the need for server intervention by designating one device as a master to analyze voice commands, determine the target device, and transmit the command, thereby enabling control of devices without voice recognition units and those located in areas where voice input cannot be collected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different feature points (start commands) are used for each home appliance to prevent operation confusion, then operation confusion is prevented, but users must memorize different starting commands for each home appliance
Solution Approach 1:
The patent applies universality by enabling a single feature point to control multiple types of electronic devices. Instead of requiring different start commands for each device type, the system allows one universal feature point to trigger voice recognition across multiple devices, eliminating the need for users to memorize device-specific commands while maintaining reliable device identification through voice analysis
2Reliability
If a server is used to select priority of voice commands among multiple electronic devices, then voice command priority can be determined, but additional server intervention is required
Solution Approach 1:
The patent applies self-service by enabling electronic devices to autonomously determine voice command priority without server intervention. Devices use local voice recognition to identify which device the user is addressing, and the targeted device automatically prioritizes and executes its own commands, eliminating the need for external server coordination while maintaining reliable priority determination
