diffuser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diffusers lack the ability to adjust airflow direction and radial angle, leading to inefficient air distribution and potential spread of pollutants in indoor spaces.
Innovation Solution
A diffuser design featuring a main body connected to an air duct with a first airflow guide that moves up and down to guide airflow horizontally and a second airflow guide with a downwardly inclined surface to direct airflow downward, allowing for adjustable airflow paths and concentration of air supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional diffuser with a fixed damper is used, then the structure is simple, but the airflow direction cannot be adjusted
Solution Approach 1:
The patent applies the dynamics principle by making the airflow guide movable rather than fixed. The first airflow guide can move vertically to switch between horizontal and downward airflow directions, while the second airflow guide can also move to adjust the downward airflow angle. This dynamic mechanism enables airflow direction adjustment without requiring complex rotating joints or multiple dampers, resolving the contradiction between adaptability and device complexity.
2Productivity
If a single airflow path is used, then the device structure is simple, but the air distribution efficiency is low
Solution Approach 1:
The patent applies segmentation by dividing the airflow into multiple paths using separate airflow guides. The first airflow guide creates a horizontal flow path, while the second airflow guide creates a downward flow path. This segmentation allows different portions of air to be distributed in different directions simultaneously, improving air distribution efficiency without requiring a completely complex multi-duct system.

AI summary
Disclosed is a diffuser. The diffuser comprises: a main body configured to be connected to an air duct installed on a ceiling, and comprising an air outlet; a first airflow guide configured to move up and down with respect to the main body to open and close at least a portion of the air outlet, and configured to guide an airflow discharged from the air outlet in response to the air outlet being opened, the first airflow guide comprising an opening configured to allow air to pass through the first airflow guide; and a second airflow guide configured to move up and down with respect to the main body and the first airflow guide to open and close the opening of the first airflow guide, and comprising a downwardly inclined surface configured to guide an airflow discharged from the opening in response to the opening being opened.
