Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation air deflection grilles are complex to adjust, often resulting in suboptimal airflow patterns due to manual adjustment of individual air deflection lamellae and potential misalignment.
Innovation Solution
The air deflection lamellae are connected via a coupling element, allowing simultaneous adjustment of multiple blades without tools, with a design that ensures easy operation and optimal airflow patterns through symmetric, adjustably mounted blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual air deflection lamellae are adjusted manually, then the adjustment can be performed without additional components, but the adjustment process becomes complex and time-consuming
Solution Approach 1:
Multiple air deflection lamellae are connected through a common coupling element that allows simultaneous adjustment of all connected lamellae by a single rotational movement, merging the adjustment function into one unified operation
Solution Approach 2:
The adjustment mechanism is segmented into modular components where each lamella can be independently connected to the coupling element, allowing flexible configuration while maintaining synchronized adjustment capability
2Adaptability or versatility
If air deflection lamellae are adjusted individually, then each lamella can be positioned independently, but misalignment occurs resulting in suboptimal airflow patterns
Solution Approach 1:
The coupling element merges the positioning function for multiple lamellae, ensuring they all achieve precise alignment simultaneously through a single adjustment action, eliminating misalignment issues while maintaining adaptability
Solution Approach 2:
The coupling element creates an equipotential adjustment state where all connected lamellae are positioned at the same angular orientation, ensuring uniform airflow distribution across all outlets
3Shape
If the gap between air deflection slats and frame sections is reduced for visual appeal, then the appearance is improved, but the coupling element becomes visible affecting the aesthetic
Solution Approach 1:
The coupling element is positioned in the rear area of the grille, utilizing the depth dimension to place the functional component outside the visible front plane, allowing narrow gap dimensions for aesthetic purposes while hiding the coupling mechanism
4Adaptability or versatility
If the distance between axes of rotation of adjacent air deflection blades is reduced, then the edge areas contact in maximum inclined position improving airflow direction, but the structural complexity increases
Solution Approach 1:
The coupling element merges the rotational control of multiple adjacent lamellae into a single mechanism, reducing structural complexity while maintaining the capability for precise airflow control through coordinated rotation of all connected blades

Implementation Method 1
at least two air deflection blades, preferably all air deflection blades, are connected via a coupling element in such a way that when the coupling element is displaced, the position of all air deflection blades connected to one another via this coupling element can be changed equally

AI summary
The ventilation air guiding grid has frame sections (1) which are spaced apart and are arranged opposing each other. Two air deflectors (2) are mounted on the frame sections and mutually positioned in parallel, where the ends of the air deflectors are rotatable about its respective axis of rotation. The deflectors are connected via a coupling element such that interconnection position of the deflectors is varied upon displacement of the coupling element.
