Device for distributing air
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air diffusers often result in uneven air distribution, with more air exiting from outlet openings opposite the inlet compared to those positioned laterally, complicating system design and planning.
Innovation Solution
A device with a housing featuring an air inlet and multiple outlet openings, incorporating a displacement element with a hollow cylinder-like cutting plane that ensures equal air flow distribution by guiding air through and around conically widening sections, maintaining symmetry and static positioning to achieve uniform air discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional air diffuser design is used, then air distribution is achieved, but uneven air flow exits from different outlet openings (more air from opposite outlet than lateral outlets)
Solution Approach 1:
The diffuser body is segmented into multiple outlet openings positioned at different locations (opposite, lateral, and angular outlets). The displacement body segments the airflow path, creating distinct flow channels that guide air uniformly to each outlet opening, resolving the uneven distribution issue.
Solution Approach 2:
The displacement body acts as an intermediary element between the inlet opening and the multiple outlet openings. It mediates the airflow by redirecting and distributing it uniformly to all outlets, preventing direct unbalanced flow paths that would cause unequal air discharge.
2Quantity of substance
If displacement body is added to achieve uniform air distribution, then air flow uniformity improves, but device complexity increases
Solution Approach 1:
The displacement body utilizes geometric parameter changes, specifically its contoured shape with varying cross-sectional area along the flow direction. This geometric design naturally guides and distributes airflow uniformly to multiple outlets without requiring complex mechanical components, control systems, or multiple moving parts.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures that approximately equal amounts of air exit from all outlet openings, simplifying system design and maintaining efficient air distribution, with air flowing through and around the displacement elements to achieve balanced airflow.
Implementation Method 1
The at least one displacement element causes the air to be distributed within the interior of the housing, so that substantially the same amount of air exits from the outlet openings on the different sides of the housing. Since the shape of the displacement element is similar to that of a hollow cylinder, the air also flows in particular through the displacement element.
