Built-In Appliance Frame Lighting for Glare-Free Status Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart home and professional devices, such as ovens, lack a clear visual indication of their operational status, making it difficult for users to determine the active program or heating state from a distance, and do not provide an aesthetically enhanced front interface.
Innovation Solution
A device with a frame element and a lighting unit that illuminates the frame, allowing the built-in appliance to be partially moved out of a niche for operation, with light sources integrated into the frame or on its rear to provide glare-free, diffuse lighting, and ventilation openings that are covered in the rest position to be exposed in the operating position, enhancing user visibility and emotional appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the built-in appliance is fully retracted into the niche, then a sleek design is achieved, but the user cannot easily recognize the operational status or program from a distance
Solution Approach 1:
The patent uses light-emitting elements (LEDs) that emit different colors or light patterns to indicate operational status, program selection, and heating state. This allows the appliance to maintain a sleek retracted design while providing clear visual information to users from a distance through color-coded status indicators.
Solution Approach 2:
The patent introduces a lighting unit with diffusing elements as an intermediary between the light sources and the user's view. This mediator allows the appliance to convey operational information through diffuse lighting patterns visible from a distance, while maintaining the sleek aesthetic when retracted, thus resolving the contradiction between design and information visibility.
2Illumination intensity
If the lighting unit is positioned on the front of the frame, then direct illumination is achieved, but glare is produced for the user
Solution Approach 1:
The patent implements local quality by positioning light sources at the rear of the frame element and using diffusing elements integrated into the frame structure. This creates localized illumination zones that provide sufficient lighting for visibility while the diffusing elements scatter the light to eliminate direct glare paths to the user's eyes.
Solution Approach 2:
Instead of placing light sources on the front side of the frame as would be conventional, the patent inverts the arrangement by positioning light sources at the rear of the frame element. This inverted configuration, combined with diffusing elements, allows illumination to pass through the frame material, providing even distribution of light without creating direct glare sources visible to users.
3Productivity
If ventilation openings are always exposed, then ventilation efficiency is improved, but the aesthetic appearance is compromised
Solution Approach 1:
The patent applies dynamics by making the ventilation openings movable rather than fixed. The ventilation openings can be dynamically adjusted between exposed and concealed positions based on operational requirements, allowing the appliance to maintain aesthetic appearance when retracted while providing efficient ventilation when in use through automated opening mechanisms.
