Household device and adjustment method with freely selectable standard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household appliances, such as washing machines, lack user-friendly options for selectively setting and varying parameter values like spin speed and temperature, especially for one-time use, and do not allow for easy differentiation between standard and customized settings.
Innovation Solution
Incorporating an assignment flag that allows users to activate a 'Standard' or 'Default' mode for parameter settings, which can be displayed and retained in memory, enabling users to modify settings for one-time use or store them for later use, with options to revert to manufacturer defaults.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users can selectively modify parameter values for one-time use, then user flexibility and ease of operation are improved, but device complexity increases due to the need for assignment flags and memory management
Solution Approach 1:
The control system segments parameter settings into two distinct modes: standard settings (affecting all program executions) and individual settings (affecting only the current execution). This segmentation is achieved through assignment flags associated with each parameter, allowing the system to manage complexity by clearly separating the two functionality types.
Solution Approach 2:
The system dynamically adjusts the scope of parameter settings based on the state of assignment flags. When a parameter has its assignment flag activated, modifications affect only the current program execution. When deactivated, modifications affect all executions. This dynamic behavior allows the system to adapt its functionality based on user needs without requiring separate hardware systems.
2Adaptability or versatility
If the system stores individual program sequences in memory, then adaptability is improved, but loss of information increases when mains supply is switched off without proper memory retention
Solution Approach 1:
The system performs preliminary actions by activating assignment flags and storing parameter modifications in memory before the mains supply is switched off. This ensures that individual program settings are preserved and can be retrieved on the next activation, preventing information loss and maintaining user customizations across power cycles.
3Adaptability or versatility
If multiple variants of main programs are available, then adaptability is improved, but device complexity increases due to additional memory requirements
Solution Approach 1:
The control system achieves multi-functionality by using a single memory structure that can store both standard parameters (affecting all programs) and individual parameters (affecting specific executions) through the use of assignment flags. This universal approach allows multiple program variants to be managed without requiring separate memory allocations for each variant, reducing overall device complexity.

AI summary
The front loading washing machine (1) has an operation panel (2) which is provided with a display (3) and several control elements (8-11) having display keys. The display is provided for displaying an automatic flow effecting control process of main program (4) and parameter values (5-7) such as washing temperature or spinner rotation speed. The display keys are provided for selecting the main program and parameter values by the control of controller. An independent claim is included for method for adjusting household appliance.
