Operating device for a household appliance having an electronic display panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operating devices for household appliances fail to combine electronic display panels with manually displaceable operating elements in a compact and mechanically stable manner, making it difficult to present information intuitively and efficiently.
Innovation Solution
An operating device with an embedded operating element within the electronic display panel, allowing for relative movement and dynamic information presentation, utilizing a rotary selector switch or touch-sensitive interface to minimize surface area and enhance user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the operating element is disposed completely within the surface dimensions of the display panel, then the device achieves compactness and minimized surface area, but the mechanical stability and operational capability of the operating element may be compromised
Solution Approach 1:
The operating element is nested within the display panel surface area, with the rotary selector switch positioned inside the boundaries of the display panel. This allows the operating device to maintain a compact form factor while integrating both components within the same surface envelope, resolving the contradiction between compactness and functional capability.
Solution Approach 2:
The display panel and operating element are merged into a single integrated unit rather than being separate components. The operating element is disposed within the display panel, creating a unified structure that minimizes surface area while maintaining both display and operational functions within the same component assembly.
2Area of stationary object
If the operating element is disposed within the display panel, then the device is minimized in terms of area, but the visibility of information on the display panel may be reduced
Solution Approach 1:
The display panel is designed to dynamically adapt its information display based on the position of the operating element. Information is selectively presented in areas of the display panel that remain visible and are contextually relevant to the current operating element position, ensuring that critical information is always accessible despite the integrated layout.
Solution Approach 2:
The display panel dynamically adjusts the presentation of information based on the rotational position of the operating element. As the user rotates the operating element, the display updates to show relevant menu items, parameters, or information corresponding to the current selection, ensuring that the most important information is always visible and contextually appropriate.
3Area of stationary object
If the operating element is disposed within the display panel, then the device achieves compact embodiment, but the ease of operation may be affected
Solution Approach 1:
The operating element is designed with a segmented structure featuring a rotary outer ring and an inner pressing element. This segmentation allows for distinct operational modes: rotating the outer ring for selection and pressing the inner element for confirmation, providing intuitive and easy operation despite the compact integrated design.
Solution Approach 2:
The operating element features a rotary selector switch with a curved, circular interface that is naturally ergonomic for finger interaction. The rotational motion follows a circular path that is easy to manipulate with a finger, and the curved design provides natural tactile feedback, enhancing ease of operation within the compact form factor.
