Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air vents with visible vanes are prone to damage and the addition of air permeable covers compromises airflow dynamics, making it difficult to achieve satisfactory directivity and airflow through the vent.
Innovation Solution
An air vent design featuring a mesh panel with vent holes and air redirecting elements that redirect airflow substantially perpendicular to the mesh panel in multiple direction modes, improving airflow directionality and flow rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an air permeable cover with small holes is arranged to cover the outlet of an air vent, then protection of internal structures is improved, but airflow directivity deteriorates
Solution Approach 1:
The air redirecting element is positioned upstream of the mesh panel to pre-direct the airflow before it reaches the cover. This preliminary action ensures that air flows substantially perpendicular to the mesh panel, optimizing penetration through the small holes and maintaining directivity despite the protective cover being in place.
Solution Approach 2:
The air redirecting element acts as an intermediary between the airflow source and the mesh panel. It modifies the airflow characteristics (direction and angle) before the air encounters the protective cover, enabling the system to simultaneously achieve protection and satisfactory airflow directivity.
2Reliability
If an air permeable cover is added to protect the air vent, then damage prevention is improved, but airflow dynamics deteriorate
Solution Approach 1:
The air redirecting element performs preliminary action by aligning the airflow perpendicular to the mesh panel before the air reaches the cover. This ensures optimal airflow dynamics and maximizes the amount of air that can penetrate through the small holes, maintaining productivity while the cover provides protection.
Solution Approach 2:
The air redirecting element changes the parameters of the airflow (specifically the angle of incidence) to be substantially perpendicular to the mesh panel. This parameter change optimizes airflow penetration through the cover, maintaining satisfactory airflow dynamics despite the presence of the protective mesh panel.
3Reliability
If the air flow hits the mesh panel at an angle, then airflow through the vent holes is reduced, but the mesh panel provides protection
Solution Approach 1:
The air redirecting element performs preliminary action by adjusting the airflow direction upstream of the mesh panel. This ensures that air arrives at the panel at substantially perpendicular angles, maximizing penetration through the vent holes and maintaining high airflow productivity while the mesh provides protection.
Solution Approach 2:
The air redirecting element changes the critical parameter of airflow angle to be substantially perpendicular to the mesh panel surface. This parameter optimization ensures maximum airflow throughput through the small vent holes while the mesh panel maintains its protective function.
