Floor Vent Assembly with Slider Mechanism for Flush Airflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor vents often protrude above the surrounding floor surface, are not designed to handle weight, and lack effective airflow regulation mechanisms, such as dampers, which can lead to inefficient heating and cooling.
Innovation Solution
A simple floor vent assembly with a slider mechanism that allows for easy airflow control by moving a slider relative to the air vent, using a molded plastic design with a support bracket for reinforcement, ensuring the vent remains flush with the floor and can handle weight without rotating mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional louvered damper is used for airflow control, then airflow regulation is achieved, but the actuator extends above the vent cover causing protrusion above the floor surface
Solution Approach 1:
The slider mechanism moves horizontally within the plane of the vent cover rather than vertically extending above it. The actuator translates linear motion in one dimension (horizontal sliding) into the desired airflow control function, eliminating the need for vertical protrusion while maintaining operational capability.
Solution Approach 2:
The slider and actuator mechanism are nested within the confines of the vent cover body. The actuator and slider assembly fit inside the vent cover structure, allowing the airflow control mechanism to be contained within the flush-mounted envelope rather than extending beyond it.
2Shape
If the vent cover is designed to fit precisely into the floor opening, then a flush installation is achieved, but the structure lacks strength to handle foot traffic and furniture weight
Solution Approach 1:
The vent cover employs a composite construction combining a rigid outer shell for structural strength with internal reinforcement elements. The body is made from durable materials that provide both the flush appearance and the necessary load-bearing capacity to support foot traffic and furniture weights.
Solution Approach 2:
The vent cover structure is divided into functional segments: a strong outer shell for structural integrity and weight bearing, an internal slider mechanism for airflow control, and a precise fitting interface for flush installation. This segmentation allows each component to be optimized for its specific function without compromising the others.
3Ease of manufacture
If a simple grille design is used, then manufacturing is simple and cost-effective, but airflow regulation capability is lacking
Solution Approach 1:
The static grille is transformed into a dynamic system by incorporating a movable slider that can shift position to adjust airflow. The slider creates variable openings that can be dynamically adjusted from fully open to partially closed positions, providing airflow regulation capability while maintaining a simple overall structure that remains easy to manufacture.
Solution Approach 2:
The simple vent cover structure is given multiple functions: it provides structural support for flush installation, houses the airflow control mechanism, and maintains an aesthetically pleasing appearance. The slider mechanism itself serves dual purposes by both regulating airflow and potentially indicating its position through visual cues.
4Adaptability or versatility
If rotatable louvers are used for airflow control, then damper function is achieved, but the mechanism becomes complex with multiple moving parts
Solution Approach 1:
The complex rotatable louver mechanism is replaced by extracting only the essential function needed: variable airflow control. The simple slider moving in a straight line within the vent cover body achieves the same airflow regulation purpose without the complexity of rotation, multiple louvers, or intricate linkages.
Solution Approach 2:
The mechanical rotatable louver system is substituted with a simpler linear sliding mechanism. Instead of rotating multiple louvers around an axis, a single slider moves horizontally to adjust the opening size, reducing mechanical complexity while maintaining airflow control functionality.

AI summary
A floor vent assembly with slots for airflow having a structure and interaction between an air vent and a slider with an actuator extending through the air vent to permit manual sliding of the slider in the floor vent assembly to selectively open/restrict the air vent for airflow. The floor vent assembly may also have an internal structural plate with corresponding slots. The user simply manually moves the actuator and thus the slider within the floor vent assembly where respective slots align or are offset to allow or restrict the flow of air through the floor vent assembly.
