Movable Display Screen Power Switch for Household Appliances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household appliances, such as washing machines, have cumbersome and inconvenient power switching mechanisms, with traditional physical key switches being cumbersome and touch-sensitive switches experiencing weak power and incomplete power-off issues, affecting user experience and appearance.
Innovation Solution
A control assembly that integrates a movable display screen connected to a power switch, allowing power-on and power-off control by pressing the screen, eliminating the need for a separate power switch key and incorporating a rebound self-locking device for complete power-off, enhancing user experience and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional physical key power switch is used, then the power switching function is reliable, but the operation becomes cumbersome and the appearance is affected
Solution Approach 1:
The patent merges the power switch function with the display screen by integrating a movable module that combines both components. When the display screen is pressed, it moves to activate the power switch, eliminating the need for a separate physical key and simplifying the control panel structure while maintaining reliable power control.
Solution Approach 2:
The movable module serves multiple functions: it acts as both the display screen and the power switch mechanism. This multi-functional design reduces the number of separate components needed on the control panel, addressing the contradiction between operational ease and device complexity.
2Device complexity
If a touch-sensitive power switch is used, then the appearance is improved, but the power-off becomes incomplete
Solution Approach 1:
The patent combines the visual appeal of a touch interface with the reliability of a mechanical switch by integrating both functions into a movable module. The physical movement of the display screen provides complete power-off reliability while maintaining the streamlined appearance of a touch-sensitive design.
3Ease of operation
If a separate power switch key is arranged on the control panel, then the power control function is independent, but the overall appearance is affected and operation becomes cumbersome
Solution Approach 1:
The patent merges the power switch key function into the display screen itself through the movable module design. This eliminates the need for a separate physical key, simplifies the control panel appearance, and makes the power switching operation more intuitive by using the familiar display screen as the activation point.

AI summary
The present disclosure provides a household appliance and a control assembly which includes a control panel, a display screen and a power switch. The display screen is arranged on the control panel and can move relative to the control panel. The power switch is connected to the control panel and/or the display screen for controlling the power-on and power-off of the household appliance. When the display screen is pressed, the display screen moves relative to the control panel and controls the power-on or power-off of the power switch. By pressing the display screen to control the power-on and power-off of the power switch, a complete power-off can be achieved to eliminate the drawbacks of weak power and incomplete power-off of the touch-sensitive power switch, and the arrangement of a power switch key is omitted, therefore the operation and the overall appearance of the household appliance is simplified.
