Extractor hood
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Extractor hoods lack attractive and visually appealing lighting solutions that also provide effective illumination for both functional and decorative purposes without dazzling users.
Innovation Solution
An extractor hood design featuring a sloping hood with a screen device, decorative device, and lighting system where LEDs are arranged to encircle the intake window, providing ambient lighting that is indirect and concealed by the decorative device, with a diffuser to ensure uniform illumination and a lighting module that includes multiple lighting groups for adjustable intensity and methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If lighting devices are arranged to provide direct illumination, then illumination intensity is improved, but user comfort deteriorates due to dazzling
Solution Approach 1:
A diffuser element is introduced as an intermediary between the light source and the user's line of sight. The diffuser scatters the light rays, transforming direct intense illumination into soft, diffuse light that provides adequate illumination intensity without causing dazzling effects to users
2Illumination intensity
If lighting components are exposed for direct viewing, then lighting effect is improved, but aesthetic appearance deteriorates due to visible mechanical components
Solution Approach 1:
A thin, translucent decorative screen is used to cover the lighting components. This screen diffuses the light while maintaining aesthetic appearance by hiding the mechanical lighting components behind an elegantly designed translucent barrier that allows light to pass through softly
Solution Approach 2:
The decorative screen incorporates color-tinted or patterned translucent material that enhances the aesthetic appearance while diffusing light. The screen can be designed with various colors or patterns that change the visual character of the light output, transforming mechanical lighting into an aesthetic feature
3Shape
If decorative device completely covers intake window, then aesthetic appearance is improved, but vapor extraction functionality deteriorates
Solution Approach 1:
The decorative screen is made from a porous or perforated material that allows vapor to pass through while maintaining aesthetic appearance. The porous structure provides sufficient open area for vapor extraction functionality while the overall screen design preserves the decorative coverage of the intake window
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 achieves particularly attractive and functional lighting effects by providing ambient and workplace lighting that is visually appealing, indirect, and energy-efficient, while ensuring the lighting components are concealed, enhancing the extractor hood's design and user experience.
Implementation Method 1
The lighting device has at least one lighting group with at least one light source
Implementation Method 2
the light generated by the illuminant or illuminants can advantageously be scattered and standardized in such a way that an essentially uniform, all-round illumination around the intake window is achieved
Implementation Method 3
the light generated by the illuminant being coupled into the glass of the screen device at least in sections
