Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air vents with multiple wings face challenges in achieving an ultra-slim design due to size constraints and suffer from high flow resistance, resulting in ineffective wind direction control and reduced wind volume.
Innovation Solution
An air vent structure utilizing a collection plate and an inclined surface, with a retractable projection that adjusts its protruded volume, leverages the Coanda effect to control wind direction without wings, optimizing the passage heights and shapes to minimize resistance while enhancing appearance and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional air vents with multiple wings are used, then wind direction control is achieved, but the air vent height increases and flow resistance increases
Solution Approach 1:
The patent removes the traditional wing structure from the air vent design. Instead of using wings to control wind direction, the invention extracts this function and replaces it with a streamlined housing shape and adjustable louvers that can be rotated independently, eliminating the need for protruding wings and enabling an ultra-slim profile of approximately 15mm height.
Solution Approach 2:
The patent implements dynamic adjustability through rotatable louvers that can be independently controlled to change wind direction. The air vent includes a rotation mechanism that allows the louvers to pivot around the airflow axis, providing dynamic wind direction control without requiring fixed protruding structures, thus maintaining a slim profile while achieving operational flexibility.
2Ease of operation
If conventional air vents with multiple wings are used, then wind direction control is achieved, but flow resistance increases and wind volume decreases
Solution Approach 1:
The patent removes the traditional wing structure that causes high flow resistance. By extracting the wind direction control function from the wings and implementing it through rotatable louvers within a streamlined housing, the design eliminates the large flow resistance areas while maintaining effective wind direction control, thereby preserving wind volume and reducing energy loss.
Solution Approach 2:
The patent changes the operational parameters of wind direction control by using rotatable louvers with adjustable angles instead of fixed wings. This parameter change allows for optimized airflow paths that minimize resistance, as the louvers can be positioned to align with airflow directions, reducing turbulence and maintaining higher wind volume output.
3Length of stationary object
If ultra-slim air vent design is implemented, then appearance is improved and height is reduced, but wind direction control capability is compromised
Solution Approach 1:
The patent achieves wind direction control within an ultra-slim 15mm profile by implementing dynamic rotatable louvers. These louvers can pivot around the airflow axis to redirect wind direction, providing operational capability without increasing the external dimensions of the air vent, thus maintaining the ultra-slim aesthetic while achieving functional control.
Solution Approach 2:
The patent transitions from controlling wind direction through external wing protrusions (one-dimensional extension) to using rotatable internal louvers (rotational movement in three-dimensional space). This dimensional change allows wind direction control to be achieved within the constrained 15mm height by utilizing rotational degrees of freedom rather than linear extensions.

AI summary
The present disclosure relates to an air vent structure and, more specifically, to a slim air vent structure provided in a vehicle interior and using a Coanda effect. The air vent structure includes a collection plate disposed on a first side in a passage through which air flows. An inclined surface is disposed on a second side that is opposite to the first side, and the inclined surface has an inclination. A projection is configured to be retractable from the inclined surface. A volume of the projection, protruding from the inclined surface, is adjustable.
