Dishwasher Single-Button Control for Program and Language Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dishwashers with a single start button, users face difficulty in accessing and changing washing programs and display language settings due to complex processes, which are typically restricted for safety reasons, limiting their ability to select alternative programs or change languages.
Innovation Solution
A dishwasher design where a single start button functions differently based on the door position, allowing users to start the automatic washing program when closed and access a setting menu for program changes and language selection when open, enabling easy access to reference programs and language options through prolonged button presses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single start button is used to simplify the interface, then device complexity is reduced, but ease of operation deteriorates because users cannot easily access setting menus or change programs
Solution Approach 1:
The patent applies dynamics by making the start button's function changeable based on door position. When the door is closed, the button starts the washing program; when the door is open, it accesses the setting menu. This dynamic functional change allows a single button to serve multiple purposes, reducing interface complexity while maintaining ease of operation for different user needs.
2Ease of operation
If the start button is made multifunctional to improve ease of operation, then ease of operation is improved, but device complexity increases due to additional control logic
Solution Approach 1:
The patent uses door position as an intermediary condition that mediates the start button's function. The control card detects door position (open/closed) and automatically determines which function to activate. This intermediary approach simplifies the control logic compared to implementing a full menu system, as the door position naturally divides the functionality into two clear states.
3Reliability
If setting menu access is restricted for safety reasons, then reliability is improved, but ease of operation deteriorates because users cannot change programs or language settings
Solution Approach 1:
The patent applies dynamics by making the start button's function changeable based on door position. When the door is closed, the button starts the washing program; when the door is open, it accesses the setting menu. This dynamic functional change allows a single button to serve multiple purposes, reducing interface complexity while maintaining ease of operation for different user needs.
