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

VSEngineering 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

Engineering Contradiction:
Improvedisplay functionVSAvoidimage quality
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

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

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvedisplay functionVSAvoidcontamination
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

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

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Inventive Principle:
Principle #2Taking out (Extraction)

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

Engineering Contradiction:
Improveheads-up display functionVSAvoidextractor hood structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improveextractor hood structureVSAvoiddigital content display options
Core Design Contradiction:
Device complexityVSAdaptability or versatility

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

Inventive Principle:
Principle #6Universality (Multi-functionality)
