Adjustable Air Outlet Directing Means for Stable Airflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air flow apparatuses with adjustable bladelike directional means suffer from wear and play issues, leading to instability and noise during direction changes, resulting in unstable air flow redirection and increased manufacturing costs and time due to numerous interconnected components.
Innovation Solution
The air flow directing means are adjustably arranged between inactive and active positions within the air flow passage, using recesses and elongate elements with air directing tongues, eliminating the need for moveable parts that wear, allowing for direct adjustment of air flow direction without play and reducing manufacturing complexity and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bladelike directional means are interconnected and adjustable in different directions, then air flow direction can be controlled, but wear and play occur leading to instability and noise
Solution Approach 1:
The patent extracts the adjustable directional control function from complex interconnected bladelike components and implements it through a single adjustable air flow directing means that can be positioned between inactive and active positions, eliminating the wear and play issues caused by multiple interconnected parts
Solution Approach 2:
The patent merges multiple adjustable bladelike directional means into a single air flow directing means that performs the same function, reducing the number of moving parts and eliminating wear between interconnected components while maintaining air flow direction control
2Adaptability or versatility
If multiple interconnected bladelike directional means are used, then air flow can be directed, but the number of moveable parts increases leading to manufacturing complexity and cost
Solution Approach 1:
The patent combines multiple separate bladelike directional components into a single integrated air flow directing means, significantly reducing the number of parts that need to be manufactured and assembled while maintaining the capability to control air flow direction
Solution Approach 2:
The single air flow directing means is designed to perform multiple functions: it can be positioned in an inactive position where it does not interfere with air flow, and in various active positions where it directs air flow in different directions, replacing the need for multiple specialized components
3Ease of operation
If bladelike directional means are adjusted, then air flow direction changes, but play between components causes noise and unstable redirection
Solution Approach 1:
The patent removes the problematic interconnected bladelike components that generate noise and instability through wear and play, replacing them with a single air flow directing means that adjusts without component interaction issues
Solution Approach 2:
The single air flow directing means is designed as a simple, robust component without complex interconnected parts, accepting that it may need replacement over time but eliminating the ongoing maintenance and noise issues associated with wear in multi-component systems

AI summary
The invention relates to an air flow apparatus (1 ) for directing an air flow (2) into a room, which air flow apparatus (1 ) comprises at least one air flow passage (3a, 3b) having at least one air flow directing means (4a, 4b) received therein for directing the air flow (2) from the airflow apparatus (1) into the room. The air flow directing means (4a, 4b) are adjustably arranged in relation to the airflow passage (3a, 3b) between an inactive and an active position. I the active position the air flow directing means (4a, 4b) physically more arranged within the air flow passage (3a, 3b) than in the inactive position. This in order to change direction the outflowing air flow (2) in and/or from the air flow passage (3a, 3b) in relation to the outflowing air flow (2) In the Inactive position.
