Active Air Intake Grille Linkage for Wider Blade Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing active air intake grilles, particularly the exposed straight waterfall type, suffer from inefficient air intake due to air flow deviation and limited opening angles, which affects heat dissipation efficiency and effective air intake area.
Innovation Solution
An active air intake grille design featuring a fixed bracket, link bracket, driving device, and link mechanisms that allow blades to rotate relative to the fixed bracket, forming adjustable air intake channels, with magnetic attraction for precise alignment and elastic components for stable movement, enabling a larger effective air intake area and improved heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the straight waterfall type grille is used with blades turning inward around a rotation axis, then the air intake can be opened and closed, but the air flow deviation occurs and the effective air intake area is reduced
Solution Approach 1:
The blade link mechanism transforms the rotation of the link bracket into rotational movement of the blades around their own axes. This dynamic mechanism allows the blades to pivot dynamically during opening/closing while maintaining their orientation relative to the air flow direction, preventing air flow deviation and maximizing the effective air intake area throughout the movement cycle.
2Device complexity
If the rotation angle of blades is limited, then the structure remains simple, but the heat dissipation efficiency is affected
Solution Approach 1:
The blade link mechanism provides dynamic adjustment capability, allowing the blades to rotate through a large angle range (nearly 90 degrees or more) as the link bracket moves. This dynamic rotation enables the air intake area to be maximized during operation, significantly improving heat dissipation efficiency while the mechanism itself remains relatively simple in structure.
3Manufacturing precision
If magnetic attraction is used for blade alignment, then precise alignment is achieved, but additional components are required
Solution Approach 1:
Magnetic attraction forces are introduced as an intermediary mechanism to achieve precise alignment between the blades and the air flow direction. The magnetic interaction provides continuous alignment force during the blade rotation process, ensuring that the blades maintain optimal orientation without requiring complex mechanical alignment mechanisms or additional adjustment components.
