Operating method for laundry machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional combo washing machines require users to manually select and input multiple options for washing, drying, and refreshing, leading to inconvenience, especially when dealing with delicate items, and often result in wrinkled or inadequately dried clothes.
Innovation Solution
An operating method for a laundry machine that allows users to select a single 'all-in-one' course, which automatically performs washing, drying, and refreshing using predetermined settings, including steam cycles, to ensure efficient wrinkle removal and drying without the need for additional user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users manually select multiple options for washing, drying, and refreshing in conventional combo washing machines, then various treatment functions can be performed, but user convenience deteriorates due to the need for multiple selections and inputs
Solution Approach 1:
The patent merges multiple separate functions (washing, drying, refreshing) into a single integrated course selection. Users select one course that automatically executes the sequence of washing → drying → refreshing operations, eliminating the need to manually select multiple separate options and improving ease of operation while maintaining full treatment functionality
Solution Approach 2:
The invention creates a universal course that performs multiple treatment functions (washing, drying, refreshing) through a single selection. This multi-functional course adapts to different treatment needs while simplifying the user interface, allowing one course to serve multiple purposes that previously required separate selections
2Adaptability or versatility
If drying is performed as an auxiliary function via option selection in conventional combo washing machines, then drying capability is provided, but operation complexity increases due to requiring additional option selection after washing
Solution Approach 1:
The patent combines the auxiliary drying function with the main washing course into an integrated sequence. The drying operation is merged into the course execution flow, automatically following washing and refreshing operations, thereby eliminating the need for separate option selection and reducing operational complexity while preserving drying capability
3Adaptability or versatility
If multiple options are required for washing course, drying option, and refreshing option in conventional machines, then comprehensive treatment is achieved, but user labor increases due to multiple selections
Solution Approach 1:
The patent merges three separate selection requirements (washing course, drying option, refreshing option) into a single course selection. The system automatically executes the comprehensive treatment sequence (washing → drying → refreshing) based on one user input, maintaining full treatment comprehensiveness while reducing user labor from multiple selections to a single action
Solution Approach 2:
The system performs self-service by automatically determining and executing the sequence of operations (washing, drying, refreshing) based on the selected course. The machine autonomously manages the multi-step treatment process without requiring continuous user input or selection, reducing user labor while achieving comprehensive treatment
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 method enables efficient and convenient treatment of clothes, ensuring a wrinkle removal score of 3.5 or more and a water percentage of 5% or less, allowing users to wear clothes immediately after the cycle is complete, while preventing damage to delicate items.
Implementation Method 1
