Dishwasher Single-Button Control for Program and Language Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing dishwashers with single buttons, users face difficulty in accessing and changing washing programs and display languages due to complex processes and safety restrictions, limiting their ability to select alternative programs or change languages without service intervention.
Innovation Solution
A dishwasher design featuring a control card with a single start button that changes functions based on the door position, allowing users to start the automatic washing program, access the setting menu, change the reference program, and select display languages through simple button presses, enabling easy program and language adjustments.
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 menu options
Solution Approach 1:
The patent applies dynamics by making the start button's function change based on the door position. When the door is closed, the button starts the washing program; when the door is open, the button provides access to the setting menu. This dynamic functional change allows a single button to serve multiple purposes, reducing device complexity while maintaining ease of operation for different user needs.
2Ease of operation
If the start button is made multi-functional to access setting menu, then ease of operation improves, but reliability deteriorates due to potential user errors
Solution Approach 1:
The patent applies local quality by associating the setting menu access function specifically with the door-open state, while the washing program start function is associated with the door-closed state. This spatial differentiation ensures that users can only access the setting menu when the door is open, preventing accidental program interruptions and maintaining reliability while providing ease of operation when needed.
3Adaptability or versatility
If additional buttons are added for program selection, then adaptability improves, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the start button to perform multiple functions: starting the washing program, accessing the setting menu, and selecting different washing programs. This multi-functionality maintains adaptability for program selection while avoiding the need for additional buttons, thus preventing an increase in device complexity.
4Ease of operation
If the setting menu is made easily accessible, then ease of operation improves, but safety deteriorates due to potential accidental changes
Solution Approach 1:
The patent applies local quality by restricting setting menu access to the door-open state, creating a spatial condition that prevents accidental changes during washing operations. Users must open the door to access settings, making the action deliberate and visible, thereby improving ease of operation when intended while preventing harmful accidental changes during closed-door washing cycles.
