Home Appliance Voice Recognition Triggered by User Actions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home appliances require users to explicitly utter a trigger command before initiating voice recognition, which can be inconvenient and inefficient, and they often consume unnecessary power by maintaining voice recognition mode consistently.
Innovation Solution
A home appliance system that detects user actions, such as opening or closing a door, to automatically initiate voice recognition mode without requiring a trigger command, and adjusts power consumption by turning off sensors and microphones when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the home appliance operates in voice recognition mode continuously to enable seamless voice recognition initiation, then the voice recognition responsiveness is improved, but the power consumption increases
Solution Approach 1:
The home appliance performs preliminary detection of user actions (such as door opening/closing, approach detection) before initiating voice recognition mode. This allows the system to activate voice recognition only when a user action is detected, rather than maintaining it continuously, thus reducing power consumption while still providing seamless voice recognition initiation when needed
Solution Approach 2:
The system periodically checks for user actions (through sensors detecting door events, approach, etc.) and transitions to voice recognition mode only when such actions are detected. This periodic monitoring approach replaces continuous operation, maintaining responsiveness to user needs while significantly reducing overall power consumption during idle periods
2Use of energy by moving object
If the home appliance requires explicit trigger command to initiate voice recognition mode, then the power consumption is reduced, but the user interaction complexity increases
Solution Approach 1:
The system performs preliminary detection of user actions (door opening/closing, user approach) before requiring a trigger command. This preliminary detection automatically prepares the system for voice recognition, eliminating the need for users to manually issue trigger commands while still maintaining power efficiency by not activating voice recognition in all states
Solution Approach 2:
The home appliance automatically detects user actions and initiates voice recognition mode without requiring explicit user commands. The system serves itself by monitoring sensor inputs (door events, approach detection) and autonomously transitioning to the appropriate mode, thereby simplifying user interaction while managing power consumption intelligently
3Speed
If the sensor and microphone remain active in standby mode to detect user actions, then the detection responsiveness is improved, but the power consumption increases
Solution Approach 1:
The sensor and microphone operate in a periodic monitoring mode during standby, detecting user actions such as door opening/closing events or user approach. When such actions are detected, the system transitions to full voice recognition mode. This periodic operation maintains detection responsiveness for key user actions while consuming significantly less power than continuous operation

AI summary
A home appliance is provided. The home appliance includes a sensor, a microphone, a speaker, and a processor. The processor is configured to, based on one of a first event wherein a user action is detected through the sensor or a second event wherein a trigger command for initiating a voice recognition mode is input through the microphone occurring, operate in the voice recognition mode, and control the speaker to output an audio signal corresponding to the event occurred, and the audio signal is an audio signal set differently for each of the first event and the second event.
