Voice Recognition Unit Vibration Shielding for Laundry Appliances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treatment apparatuses with voice recognition units face challenges in accurately recognizing user commands due to sensitivity to vibrations from operation and external noise, leading to reduced recognition accuracy and user inconvenience.
Innovation Solution
The integration of a shielding portion that includes an installation unit, a cover with a through-hole to transmit user voice while attenuating vibrations and external noise, and a shock absorber to prevent unwanted vibrations from reaching the voice recognition unit, enhancing its accuracy and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a voice recognition unit is installed in the laundry treatment apparatus to enable voice control, then user convenience is improved, but the recognition accuracy deteriorates due to sensitivity to vibrations from drum rotation and water supply/drainage operations
Solution Approach 1:
The voice recognition unit is separated from the main apparatus body and installed in a separate location (exterior of the cabinet or door). This spatial segmentation isolates the sensitive voice recognition component from the vibration-generating components (drum, water supply/drainage system), allowing voice control functionality to be maintained without compromising recognition accuracy due to operational vibrations.
Solution Approach 2:
A vibration isolation mechanism or damping structure is introduced as an intermediary between the voice recognition unit and the apparatus body. This intermediary component absorbs or blocks vibrations transmitted from the drum rotation and water supply/drainage operations, protecting the voice recognition unit from harmful vibrations while maintaining its ability to detect voice commands.
2Measurement precision
If the voice recognition unit is made highly sensitive to detect voice commands, then recognition capability is improved, but the unit becomes overly sensitive to vibrations from apparatus operation and external noise, worsening recognition reliability
Solution Approach 1:
The voice recognition unit is positioned in a specific location with favorable acoustic and vibration characteristics (exterior of cabinet or door, away from vibration-generating components). This local positioning provides a relatively stable environment that maintains voice detection sensitivity while reducing exposure to harmful vibrations and external noise, thereby improving recognition reliability.
Solution Approach 2:
A vibration isolation mechanism or damping structure is introduced as an intermediary between the voice recognition unit and the apparatus body. This intermediary component absorbs or blocks vibrations transmitted from the drum rotation and water supply/drainage operations, protecting the voice recognition unit from harmful vibrations while maintaining its ability to detect voice commands.
3Adaptability or versatility
If the voice recognition unit is installed inside the apparatus to maximize space utilization, then space efficiency is improved, but vibration from internal components directly affects the unit, worsening recognition accuracy
Solution Approach 1:
The voice recognition unit is separated from the main apparatus body and installed in a separate location (exterior of the cabinet or door). This spatial segmentation isolates the sensitive voice recognition component from the vibration-generating components (drum, water supply/drainage system), allowing voice control functionality to be maintained without compromising recognition accuracy due to operational vibrations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly improves the voice recognition unit's ability to accurately recognize user commands even during operation and external noise interference, enhancing user convenience and reliability.
Implementation Method 1
a cover (230) coupled to a front side of the installation unit (210) to shield the voice recognition unit (300), and a through-hole (231) configured to penetrate the cover (230) to transmit the voice to the voice recognition unit (300)
Implementation Method 2
a shock absorber (220) disposed between the installation unit (210) and the voice recognition unit (300) to prevent vibrations or sound waves generated from the laundry receiving portion (100) or transmitted to the cabinet (10) from being transmitted to the voice recognition unit (300)

AI summary
Disclosed is a laundry treatment apparatus including a voice recognition unit coupled to any one of a cabinet and a door to receive voice of a user and convert the voice into an input signal for driving a laundry receiving portion, and a shielding portion coupled to at least one of the cabinet or the door to prevent vibrations or sound waves generated from the laundry receiving portion from being transmitted to the voice recognition unit.
