Solution Overview

Problem

Existing fume extraction devices are limited in their ability to spatially target and effectively remove vapors and odors in cooking areas, often requiring fixed installations and lacking flexibility to adapt to different cooking setups, which can lead to incomplete removal of hazardous fumes and odors.

Innovation Solution

A modular fume extraction device with adjustable and movable components, including fume limitation modules and extraction openings, allowing for flexible positioning and alignment to specifically target vapor sources, combined with an air supply system to create an air curtain for effective fume separation and extraction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed installation fume extraction devices are used, then the device structure is simple and easy to install, but the device cannot adapt to different cooking setups and cannot effectively target vapor sources

Engineering Contradiction:
Improveadaptability to different cooking setupsVSAvoiddevice structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fume extraction device incorporates movable components including a height-adjustable hood assembly that can move vertically along the cooktop, and a rotatable extraction unit that can pivot to face different cooking zones. This dynamic positioning capability allows the device to adapt to various cooking setups and target vapor sources effectively, while maintaining a relatively simple overall structure through the use of guide rails and pivot joints.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If movable components are added to enable flexible positioning, then the adaptability to different cooking setups is improved, but the device complexity increases

Engineering Contradiction:
Improveease of positioning and alignmentVSAvoidnumber of movable components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device is divided into modular segments: a stationary base unit, a height-adjustable hood assembly that moves independently on guide rails, and a rotatable extraction unit with pivot joints. This segmentation allows each component to be adjusted independently for easy positioning, while the modular design prevents the complexity from becoming unmanageable by maintaining clear functional boundaries between segments.

Inventive Principle:
Principle #1Segmentation

3Productivity

If the extraction device is designed to target specific vapor sources, then the effectiveness of fume removal is improved, but the device cannot be easily repositioned for different cooking areas

Engineering Contradiction:
Improveeffectiveness of fume removalVSAvoidability to extract from different spatial regions
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The extraction device features a rotatable extraction unit with pivot joints that can rotate horizontally and vertically to face different cooking zones, and a height-adjustable hood assembly that can move along guide rails to position the extraction opening at optimal heights. This dynamic positioning system maintains high extraction effectiveness for targeted vapor sources while enabling easy repositioning for different cooking areas.

Inventive Principle:
Principle #15Dynamics
