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 against damage and design freedom are improved, but airflow dynamics are compromised and directivity is reduced
Solution Approach 1:
The patent changes the geometric parameters of the mesh panel, specifically the shape and orientation of vent holes, to optimize airflow characteristics. The elongated vent holes oriented perpendicular to the dominant airflow direction reduce flow resistance and improve directivity while maintaining protection functionality.
Solution Approach 2:
The mesh panel acts as a composite structure combining protective coverage with controlled permeability. The specific geometric configuration of vent holes within the mesh panel creates a composite functionality that simultaneously provides protection and optimized airflow dynamics.
2Reliability
If an air permeable cover with small holes is arranged to cover the outlet of an air vent, then protection against damage and design freedom are improved, but directivity is reduced
Solution Approach 1:
The patent optimizes geometric parameters including elongating vent holes in the mesh panel and orienting them perpendicular to the dominant airflow direction. This parameter change enhances directivity by guiding airflow more effectively through the cover while maintaining protection.
Solution Approach 2:
The mesh panel features non-uniform local characteristics with elongated vent holes strategically oriented to match local airflow patterns. This local optimization of hole geometry and orientation improves directivity in specific directions while maintaining overall protective coverage.
3Ease of operation
If conventional vanes are used to redirect airflow, then directivity is improved, but vulnerability to damage from exterior objects and human interaction increases
Solution Approach 1:
The mesh panel serves as an intermediary element between the airflow control mechanism and the external environment. It provides protective coverage that shields internal vanes and structures from direct exposure to exterior objects while still allowing controlled airflow through its permeable structure.
Solution Approach 2:
The mesh panel functions as a thin film structure that provides protective coverage without the rigidity and vulnerability of solid covers. Its flexible, permeable nature allows it to withstand external interactions while maintaining airflow functionality.

AI summary
Air vent including mesh panel with improved directivity. In general, the disclosed subject matter relates to an air vent which comprises a mesh panel with vent holes to cover an outlet of the air vent, wherein the air vent provides for improved directionality of the outlet air through the mesh panel. The improvement in directivity is provided by that the air flowing towards the mesh panel is directed to flow substantially perpendicular to the mesh panel in at least some direction modes of the air redirecting element.
