Display apparatus and home appliance having the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home appliance displays are limited in projecting image information externally due to the integration of image generators and adjustors as separate modules, which increases the volume and complicates installation, especially when aiming to project images onto a surface below the appliance.
Innovation Solution
A compact display apparatus is designed with an image generator and adjustor housed within a single unit, allowing the image generator to project light and the adjustor to adjust the image size, with the adjustor moving relative to the image generator to change the projection distance and focus, enabling larger image projection onto a surface below the appliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the image generator and adjustor are integrated as separate modules, then the image projection function is achieved, but the volume of the display apparatus increases and installation becomes complicated
Solution Approach 1:
The patent combines the image generator and adjustor into a single integrated module, eliminating the need for separate module installation and reducing overall device complexity while maintaining all necessary functions
2Ease of manufacture
If the image generator and adjustor are integrated as separate modules, then the image projection function is achieved, but the volume of the display apparatus increases
Solution Approach 1:
The patent merges the image generator and adjustor into one compact integrated module, significantly reducing the overall volume of the display apparatus while maintaining ease of manufacturing and assembly
Solution Approach 2:
The adjustor is positioned within the housing that also contains the image generator, with components nested efficiently to minimize the external dimensions of the display apparatus
3Adaptability or versatility
If the adjustor moves relative to the image generator, then the image size adjustment is achieved, but the mechanical complexity increases
Solution Approach 1:
The patent implements a movable adjustor that can shift position relative to the image generator along the optical axis, enabling dynamic adjustment of image size and focus without requiring complex mechanical mechanisms
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
This configuration minimizes the display apparatus' volume, allowing easy installation and adjustment of image size and resolution, enhancing user visibility of the projected image.
Implementation Method 1
an illumination lens configured to condense light generated by the light source to the display device
Implementation Method 2
an adjustor including a reflective lens configured to adjust a size of the image projected from the display apparatus
Data Source
AI summary
Disclosed herein is a home appliance comprising a front panel and a display apparatus disposed to a rear of a rear side of the front panel. The display apparatus includes an image generator including a light source configured to generate a light; a lens configured to condense the light generated by the light source; and a display device configured to generate an image thereon from the condensed light, and to transmit at least a portion of the condensed light so that the image is projected downward from the image generator to a surface outside of the home appliance; and an adjustor including a lens configured to move relative to the image generator to adjust a size of an image projected downward from the image generator to the surface.
