Solution Overview
Problem
Existing fully integrated kitchen appliances, such as dishwashers and refrigerators, face challenges in providing a clear and visually appealing illuminated display on their doors, as projection-based solutions can be difficult to see from a distance and look unappealing when inactive.
Innovation Solution
A display device with illuminated elements, such as LEDs and light guides, is integrated into the door, protruding into a recess in the panel, allowing the display to shine through a translucent cover, ensuring visibility and a seamless appearance when active, while being concealed when inactive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a projection device is used to display information on the floor, then the display can be provided on the appliance, but the display is difficult to see from a distance and is not clearly visible
Solution Approach 1:
The display device is moved from projecting onto the floor (2D surface) to being integrated into the door panel itself (3D structure with recess), allowing the display to be positioned at an optimal viewing distance and angle, thereby improving visibility and detectability from a distance
2Ease of operation
If the display device is integrated into the door, then the display is always visible, but the aesthetic integrity of the panel is compromised when inactive
Solution Approach 1:
The display device is nested within a recess in the door panel, allowing it to be concealed when inactive and only become visible when illuminated, thus maintaining panel aesthetics while ensuring display accessibility when needed
Solution Approach 2:
The panel area containing the display changes from opaque (when display is off) to translucent (when display is illuminated), creating a visual transformation that maintains aesthetic integrity in inactive state while providing visibility when active
3Shape
If a recess is made in the panel for the display device, then the display can be integrated seamlessly, but the manufacturing complexity increases
Solution Approach 1:
The manufacturing process is segmented into distinct steps: creating the recess in the panel, mounting the display device separately, and then integrating it into the panel, which simplifies each individual step while achieving seamless integration
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a clear, bright, and visually appealing illuminated display that is easily recognizable, even when the appliance is not in operation, without compromising the aesthetic integrity of the appliance's front panel.
Implementation Method 1
A display device is arranged on the door, which has or forms an illuminated display... light-conducting bodies or light guides... the illuminated display shines through the cover

AI summary
An electrical appliance in the form of a dishwasher (11) or a refrigerator for installation in a kitchen (1) has an essentially full-surface door (13) for opening on a front side and a panel (30) to be attached to the front of this door over the entire surface. A display device (17) with an illuminated display (18) is arranged on the door (13), at least part of the display device protruding beyond the front side of the door (13). A recess (32) corresponding to the protruding part of the display device (17) is provided in the bezel (30) so that this part is located therein. A film (40) is then glued over the entire surface of the door as a lamination, the film being translucent in such a way that the illuminated display (18) shines through it when activated and can be seen.
