Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air vents for motor vehicles require visible fins or multiple outlet openings to direct airflow, which complicates design, reduces aesthetic appeal, and increases mechanical complexity and wear.
Innovation Solution
An air vent design utilizing a conical air guiding element and the Coanda effect to direct airflow without external fins or multiple outlets, featuring a slide with a stopper that covers the inlet opening and a manipulator for adjusting airflow direction and intensity, along with planar elements for additional guidance and low-friction movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fins or multiple outlet openings are used to direct airflow, then airflow direction control is improved, but device complexity and aesthetic appearance deteriorate
Solution Approach 1:
The patent extracts the airflow direction control function from traditional visible fins and multiple outlets, implementing it through a single outlet opening with an internal conical air guiding element that directs airflow using the Coanda effect, thereby simplifying the external structure while maintaining directional control capability
Solution Approach 2:
The patent introduces a conical air guiding element as an intermediary component inside the nozzle housing that mediates airflow direction by creating a curved surface that guides the air jet along its contour, enabling directional control without external fins or multiple openings
2Ease of operation
If fins or multiple outlet openings are used to direct airflow, then airflow direction control is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The patent removes the need for visible external fins and multiple outlet openings by extracting the airflow direction control function to an internal conical air guiding element, resulting in a clean single-opening design that maintains aesthetic appearance while providing directional control
Solution Approach 2:
Instead of directing airflow outward through multiple openings or fins as in conventional designs, the patent inverts the approach by using a single opening with an internal conical element that curves the airflow path, achieving direction control from the inside out with a simpler external appearance
3Ease of operation
If traditional air guiding elements are used, then airflow direction is improved, but mechanical stability and durability deteriorate
Solution Approach 1:
The patent merges the airflow direction control function into the conical air guiding element that is integrated within the nozzle housing, reducing the number of separate moving parts and external components, thereby improving mechanical stability and durability while maintaining directional control capability
4Adaptability or versatility
If multiple moving components are used for airflow control, then airflow adjustment flexibility is improved, but wear and maintenance requirements worsen
Solution Approach 1:
The patent combines multiple airflow control functions (direction control, flow rate adjustment) into a single integrated conical air guiding element with a slide mechanism, reducing the number of moving components and minimizing wear points while maintaining adjustment flexibility
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 design achieves a clean aesthetic, high mechanical stability, durability, and reduced wear due to fewer moving components, while allowing for easy airflow direction and intensity adjustment.
Implementation Method 1
the air vent according to the invention makes use of the Coanda effect. Due to the Coanda effect, the air runs along the inside of the nozzle housing and thus along the conical air guide element without detaching from these surfaces
