Sensor-Triggered Voice Recognition in Home Appliances
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 continuously.
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 dynamically switches between voice recognition and standby modes based on user input, reducing power consumption by turning off unnecessary components 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 initiation, then user convenience is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts its operational state based on detected user presence. When a user is detected via sensor, the system transitions to voice recognition mode; when no user is present, it returns to standby mode. This dynamic state adjustment resolves the contradiction by enabling convenient voice recognition only when needed, rather than maintaining it continuously.
Solution Approach 2:
The system employs periodic sensor detection to monitor user presence and triggers voice recognition mode intermittently based on these detections. This periodic activation rather than continuous operation reduces power consumption while maintaining the capability for seamless voice initiation when a user is present.
2Use of energy by moving object
If the home appliance requires explicit trigger command to initiate voice recognition, then power consumption is reduced, but user convenience deteriorates
Solution Approach 1:
The system performs preliminary sensor detection to identify user presence before activating voice recognition mode. This preliminary action eliminates the need for users to explicitly issue trigger commands, as the system proactively prepares the voice recognition capability in advance when it detects a user is present, thereby improving convenience without excessive power consumption.
3Ease of operation
If the home appliance uses sensor detection to automatically initiate voice recognition mode, then user convenience is improved, but device complexity increases
Solution Approach 1:
The system segments the control functionality into distinct modules: sensor detection module, voice recognition module, and control logic module. This segmentation allows each component to perform its specific function independently, simplifying the overall system architecture while enabling automatic initiation of voice recognition based on sensor input.

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.
