Solution Overview
Problem
Users often experience unpleasant odors when taking out cleaned tableware from a dishwasher due to prolonged exposure, requiring manual odor removal processing which can be forgotten or inconvenient, leading to a suboptimal user experience.
Innovation Solution
A method and apparatus for controlling a dishwasher that predicts the user's tableware taking-out time based on operation and active time data, automatically initiating odor removal processing before the tableware is removed, utilizing a human body sensor assembly and historical behavior data to enhance user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dishwasher operates continuously to maintain cleaning readiness, then the tableware remains clean, but odor develops due to prolonged exposure
Solution Approach 1:
The system performs odor removal processing in advance before the user actually takes out the tableware. By predicting the taking-out time based on historical data and initiating odor removal beforehand, the system eliminates odor before it becomes a problem, resolving the contradiction between maintaining cleaning readiness and preventing odor development.
2Object-affected harmful factors
If the user manually initiates odor removal processing, then odor can be removed, but the operation becomes complex and may be forgotten
Solution Approach 1:
The dishwasher system automatically performs odor removal processing without requiring user intervention. The control unit autonomously monitors operation time, predicts when tableware will be taken out, and initiates odor removal independently, making the system self-serve and eliminating the burden on users to remember and manually start odor removal.
Solution Approach 2:
The system uses historical behavior data and operation time feedback to continuously improve its prediction accuracy. By analyzing past patterns of when users take out tableware, the system refines its predictions and optimizes the timing of odor removal processing, creating a closed-loop system that adapts to user behavior.
3Ease of operation
If the dishwasher automatically performs odor removal, then user convenience is improved, but energy consumption increases
Solution Approach 1:
The system performs odor removal processing partially and selectively based on predicted necessity rather than continuously. By using historical behavior data to predict when tableware will be taken out, the system activates odor removal only when needed, avoiding unnecessary energy consumption while maintaining user convenience.
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 automates odor removal before tableware is taken out, reducing user complexity and improving the overall experience by ensuring the tableware is removed in a fresh condition, thus enhancing user satisfaction and convenience.
Implementation Method 1
The active time set includes at least one active time instance at which an occurrence of a human body activity in a predetermined region of the dishwasher is sensed by the human body sensor assembly
Data Source
AI summary
A control method includes obtaining an active time set in a predetermined time period that includes an active time instance at which a human body sensor assembly of a dishwasher detects human body activity in a predetermined region of the dishwasher, obtaining operation time of the dishwasher in the predetermined time period, predicting a tableware taking-out time point based on the active time set and the operation time, and controlling, at a target time point, the dishwasher to perform odor removal processing. The target time point is at a time length before the tableware taking-out time point.
