Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hood systems inefficiently discharge cooking oil fumes, leading to health risks such as lung cancer due to the wide distance between fume generation and suction, and reduced efficiency in narrow and wide spaces.
Innovation Solution
An artificial intelligence range hood with a movable intake and exhaust duct that adjusts vertically, combined with a control unit to manage suction and discharge based on harmful substance detection, allowing 360° fume collection and filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional hood system is installed at a distance above a range, then the hood body structure is simple and easy to install, but the distance between cooking oil fume generation point and suction point is wide, resulting in poor suction efficiency and health hazards
Solution Approach 1:
The patent introduces a movable intake and exhaust duct that can adjust its position dynamically. This duct can move vertically along a guidance hole to change the distance between the suction opening and the cooking surface, allowing the system to adapt to different cooking scenarios and maintain optimal suction efficiency while remaining installable in various configurations.
2Ease of manufacture
If suction ducts are formed in a circular hole structure with an open lower portion, then the device complexity is low and manufacturing is easy, but the suction and discharge efficiency is significantly reduced in wide places
Solution Approach 1:
The patent segments the suction system into multiple components: a fixed intake and exhaust duct for structural support, a movable intake and exhaust duct for adaptive positioning, and a discharge mode conversion unit with selectable openings. This segmentation allows each component to perform its specific function optimally while maintaining manufacturing feasibility.
Solution Approach 2:
The patent adds vertical movement capability to the suction system through the movable duct that travels along a guidance hole. This transforms the static circular suction opening into a dynamic three-dimensional suction zone that can adjust its position vertically to effectively capture fumes in both narrow and wide cooking spaces.
3Device complexity
If a fixed hood structure is used, then the device complexity is low, but the system cannot adapt to different cooking scenarios or optimize suction in narrow versus wide spaces
Solution Approach 1:
The patent introduces a movable intake and exhaust duct that can adjust its position dynamically. This duct can move vertically along a guidance hole to change the distance between the suction opening and the cooking surface, allowing the system to adapt to different cooking scenarios and maintain optimal suction efficiency while remaining installable in various configurations.
Solution Approach 2:
The patent adds vertical movement capability to the suction system through the movable duct that travels along a guidance hole. This transforms the static circular suction opening into a dynamic three-dimensional suction zone that can adjust its position vertically to effectively capture fumes in both narrow and wide cooking spaces.
4Device complexity
If cooking oil fumes are discharged only from an upper portion of the hood, then the hood body structure is simple, but the discharge distance is wide and users may breathe in harmful fumes
Solution Approach 1:
The patent segments the discharge system into multiple components: a fixed intake and exhaust duct for structural support, a movable intake and exhaust duct for adaptive positioning, and a discharge mode conversion unit with selectable openings. This segmentation allows each component to perform its specific function optimally while maintaining manufacturing feasibility.

AI summary
The present invention relates to an artificial intelligence range hood which may rapidly and easily discharge cooking oil fumes and indoor polluted air by selectively opening or closing a movable intake and exhaust duct or an indoor polluted air intake and exhaust duct, may prevent industrial accidents in advance, such as lung cancer that may be caused by continuously sucking cooking oil fumes including various harmful substances by a reference amount or more, may automatically create a pleasant indoor air quality environment by significantly improving indoor air quality, may rapidly suck and discharge the cooking oil fumes by lowering the movable intake and exhaust duct to a portion where the cooking oil fumes are generated, and may rapidly discharge the cooking oil fumes by allowing the cooking oil fumes to sequentially pass through the movable intake and exhaust duct and a fixed intake and exhaust duct after the cooking oil fumes are collected into a cooking oil fume suction hole in a 360° lateral direction of an oil drip tray, thereby protecting the health of a cook.
