Extractor hood device with imaging area element for digital content and kitchen appliance with extractor hood device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kitchen extractor hood devices with projected digital content face issues due to irregular surfaces and contamination, leading to distorted and degraded image quality, and existing solutions have complex structures or lack integration with kitchen arrangements.
Innovation Solution
An extractor device with a vertically movable extension element featuring an imaging surface element made of transparent material with surface treatment, allowing for high-quality digital content projection while maintaining a simple structure and easy cleaning, integrated into a kitchen worktop or cabinet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital content is projected onto a room wall or existing surface, then a display function is added to the kitchen, but the image quality is degraded due to irregular surfaces and contamination
Solution Approach 1:
A projection screen is introduced as an intermediary element between the projector and the wall. This dedicated screen surface provides a smooth, contamination-resistant display area that does not suffer from the irregularities and grease accumulation problems of the wall surface, thereby maintaining high image quality while enabling digital content display in the kitchen environment
Solution Approach 2:
The display function is segmented from the wall surface and implemented on a separate, dedicated projection screen. This allows the screen to be optimized specifically for projection purposes with appropriate surface properties, while the wall remains unchanged, resolving the conflict between adding display functionality and maintaining image quality
2Adaptability or versatility
If a projection surface is placed behind the cooktop, then digital content can be displayed in the kitchen, but the surface is exposed to grease particles and contaminants from cooking fumes
Solution Approach 1:
The projection screen acts as an intermediary that is specifically designed and positioned to be protected from contaminants. It can be integrated into the extractor hood structure or positioned in the airflow path, allowing it to be shielded from grease particles while still serving its display function
Solution Approach 2:
The projection screen is extracted from the contaminated environment behind the cooktop and positioned within the extractor hood structure or in a protected location. This separates the display surface from the harmful cooking fumes and grease particles, preventing contamination while maintaining the display function
3Adaptability or versatility
If a complex structure with vertically movable columns and transparent splash guard is used for the extractor hood, then a heads-up display can be projected onto the splash guard, but the device complexity increases
Solution Approach 1:
The projection screen is merged with the extractor hood structure itself, eliminating the need for separate vertically movable columns and transparent splash guards. The screen is integrated into the hood's existing components, such as the baffle plate or front surface, thereby achieving the heads-up display function without increasing device complexity
4Device complexity
If the extractor hood is integrated into the worktop with a simple structure, then the design is simplified and modern, but the options for displaying digital content are limited
Solution Approach 1:
The extractor hood structure is designed with multi-functionality, serving both its primary ventilation purpose and as a platform for digital content display. The projection screen is integrated into the hood structure, allowing the simple, modern extractor hood to simultaneously provide vapor extraction and digital content output without requiring additional complex components
