Air Outlet with Adjustable Discs for High-Volume Cooling and Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air outlets are inadequate for introducing large volumes of air (over 10,000 m3/h) from great heights into large spaces such as halls or airport buildings, both for cooling and heating efficiently.
Innovation Solution
An air outlet design featuring an adjusting device with rotating disks that automatically controls air passage by vertical movement, distinguishing between cooling and heating modes, and utilizing a spindle drive and guide columns for precise vertical guidance, along with an outer ring to manage air flow through nozzles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing air outlets are used to introduce large volumes of air from great heights, then air delivery capability is improved, but the ability to efficiently switch between cooling and heating modes is insufficient
Solution Approach 1:
The air outlet employs dynamic adjustment mechanisms including rotatable adjustment discs with variable openings and movable guide elements that can change the airflow pattern in real-time. These dynamic components allow the same air outlet to efficiently deliver both cooling air (with high vertical throw) and heating air (with diffusion pattern), resolving the contradiction between high air volume delivery and adaptability to different thermal modes.
2Ease of manufacture
If fixed air flow patterns are used in air outlets, then manufacturing simplicity is improved, but the ability to influence air flow and induction is limited
Solution Approach 1:
The air outlet is segmented into multiple functional components: adjustment discs with multiple opening patterns, separate guide elements for cooling and heating modes, and modular mounting structures. This segmentation allows each component to be manufactured independently with standard processes while providing complex adjustable airflow control when assembled, resolving the contradiction between manufacturing simplicity and operational flexibility.
3Device complexity
If simple adjustment mechanisms are used, then device complexity is reduced, but the precision of air flow control is insufficient
Solution Approach 1:
The patent introduces intermediary elements such as adjustment discs with precisely positioned openings, guide vanes, and linkage mechanisms that translate simple rotational or linear movements into precise airflow direction changes. These intermediaries amplify small adjustment inputs into accurate airflow control, resolving the contradiction between simple device complexity and high manufacturing precision.

AI summary
In the case of an air outlet for releasing air with a nozzle (1) which is connected to an air guidance system and with a front plate (3) from which at least part of an airflow exits, an adjustment device (11) for changing the airflow is to be assigned to the front plate (3) inside the outlet, the distance of which to the front plate (3) is to be changed.
