Household appliance with control element and and method for operating a household appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of household appliances face difficulties in resetting operating parameters after incorrect operation, often forgetting the adjusted values and dealing with multiple changes that complicate the resetting process.
Innovation Solution
Incorporating a reset control element that allows operators to easily revert to original settings by actuating a dedicated button or switch, with options for resetting single or multiple changes, including time-dependent and state-specific configurations, to simplify the resetting process without needing to remember the adjusted values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a control element is operated incorrectly, then the operating parameter changes, but the user cannot easily reset to the original value
Solution Approach 1:
The system stores the original operating parameter value in advance before any changes occur. This preliminary storage of information allows the user to reset to the exact original value without needing to remember it, directly resolving the contradiction between ease of resetting operation and loss of original value information.
2Ease of operation
If multiple operating parameters are changed, then the complexity of resetting increases, but a simple reset mechanism is needed
Solution Approach 1:
The reset function is segmented into two distinct modes: a first reset mode that resets to the original stored value, and a second reset mode that sequentially undoes individual changes. This segmentation allows the system to handle multiple parameter changes while maintaining simplicity through mode selection, resolving the contradiction between ease of operation and device complexity.
3Ease of operation
If a reset function is added, then resetting becomes easier, but the device complexity increases
Solution Approach 1:
The control element is designed with multi-functionality, where existing control elements serve both their primary function of changing parameters and a secondary function of initiating reset operations through specific operation patterns (e.g., prolonged pressing or specific sequences). This universality adds the reset capability without requiring entirely new dedicated hardware components, thus improving ease of operation while minimizing increases in device complexity.
