Solution Overview

Problem

Fixed-type hoods installed over cooking equipment are ineffective in removing oil mist due to their fixed position and height, leading to odors and grease stains on walls and furniture, and are not portable for outdoor cooking.

Innovation Solution

A portable air flow apparatus with a head unit, base unit, and columnar unit that allows adjustable positioning of the suction inlet and discharge outlet, preventing bypass phenomena and enabling efficient suction and discharge of oil mist, and can be used both indoors and outdoors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a fixed-type hood is installed over cooking equipment, then the hood structure is simple and installation is easy, but the hood cannot effectively remove oil mist when cooking occurs at positions far from the hood

Engineering Contradiction:
Improvehood installation simplicityVSAvoidoil mist removal efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent transforms the fixed-type hood into a mobile cart-mounted hood that can be freely positioned and adjusted. The hood is mounted on a cart with wheels, allowing it to move to different cooking locations. The height of the hood is also adjustable via a height adjustment mechanism, enabling dynamic adaptation to various cooking positions and utensil heights, thereby maintaining effective oil mist removal efficiency while preserving installation simplicity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mobile hood is designed to serve multiple cooking scenarios - it can be used with fixed cooking equipment, portable burners, and outdoor cooking setups. The cart structure includes features like a water tank for stabilizing the cart during use, and the hood itself can be adjusted to different heights and angles, making it universally applicable to various cooking methods and locations, thus improving oil mist removal efficiency across different contexts while maintaining ease of deployment.

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

2Ease of operation

If the hood is installed at a great height from the cooking equipment, then the hood does not interfere with cooking operations, but oil mist is not effectively removed due to long distance

Engineering Contradiction:
Improvecooking operation convenienceVSAvoidoil mist removal efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The height adjustment mechanism allows the hood to be dynamically positioned at optimal heights for different cooking scenarios. The hood can be lowered close to the cooking surface when needed for effective oil mist capture, or raised higher when cooking operations require more space. This dynamic height adjustment resolves the contradiction by allowing the hood to adapt its position based on the specific cooking situation, maintaining both operational convenience and removal efficiency.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If a fixed-type hood is used, then the hood structure is stable, but the hood cannot be used for portable cooking or outdoor cooking

Engineering Contradiction:
Improvehood structural stabilityVSAvoidcooking location flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The mobile cart structure provides both stability and mobility. The cart has a stable base with a water tank that acts as a counterweight to stabilize the hood during operation, preventing tipping while allowing easy movement via wheels. This dynamic design enables the hood to be transported to outdoor locations or different rooms while maintaining structural stability during use, thus resolving the contradiction between stability and versatility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The water tank in the cart serves as a counterweight to balance the hood and prevent the cart from tipping over during operation. This counterweight mechanism provides structural stability to the mobile hood system, ensuring that even though the hood is portable and can be moved to various locations, it remains stable and secure during cooking operations, thus maintaining both stability and adaptability.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

4Device complexity

If the suction inlet is positioned far from the cooking surface, then the hood structure is simple, but bypass phenomena occur and oil mist removal efficiency decreases

Engineering Contradiction:
Improvehood structure simplicityVSAvoidoil mist removal efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The mobile hood design allows the suction inlet to be dynamically positioned close to the cooking surface by moving the entire hood unit on the cart. The height adjustment mechanism further enables fine-tuning of the inlet position. This dynamic positioning capability eliminates bypass phenomena by ensuring the suction inlet is always in optimal proximity to the cooking surface, maintaining removal efficiency without significantly increasing structural complexity, as the adjustment mechanisms are relatively simple.

Inventive Principle:
Principle #15Dynamics

AI summary

A portable air flow apparatus may include a base configured to be seated on a surface, a head comprising a suction inlet through which air is suctioned into the head and a discharge outlet through which the air suctioned in through the suction inlet is discharged, the suction inlet and the discharge outlet being horizontally spaced apart from each other at a right angle with respect to a vertical direction, and a column that connects the head and the base in such a manner that the head is vertically spaced from the base.
