Method for operating a laundry washing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laundry washing machines require users to manually select operating programs and parameters, which can be time-consuming and inefficient, especially as user habits and laundry quantities change over time.
Innovation Solution
A method and device that automatically determine the quantity of laundry, select the most frequently used operating program based on prior usage, and display associated parameters, allowing for easy operation with options to modify settings for optimal washing results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually selects operating programs and parameters, then the user can control washing settings, but the operation becomes time-consuming and inefficient
Solution Approach 1:
The washing machine automatically determines the quantity of laundry and selects the operating program based on historical usage data, enabling the system to serve itself by making intelligent decisions without requiring manual user input for program selection
Solution Approach 2:
The system stores and analyzes historical usage data from previous wash cycles, using this feedback information to automatically select the most frequently used program for the current laundry quantity, thereby learning from past user preferences
2Adaptability or versatility
If the washing machine offers fixed predetermined programs, then the device complexity is reduced, but the adaptability to user habits and changing laundry quantities is limited
Solution Approach 1:
The system pre-stores multiple operating programs with their associated parameters in memory before operation, organized by laundry quantity ranges, enabling rapid automatic selection without real-time computation or complex processing during the wash cycle initiation
Solution Approach 2:
The system varies the selected operating program and its parameters based on the determined laundry quantity and historical usage patterns, dynamically adjusting washing settings to match both the load size and user preferences
