Wall-Mounted Fan Air Circulation for Floor Refinishing Curing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air circulation systems are not suitable for use during floor refinishing as they cannot operate on a 'wet' floor and may interfere with the curing process if air is circulated prematurely, leading to skinning issues.
Innovation Solution
An air circulation system that includes a vertically mounted fan supported by an outlet tap connected to a wall receptacle, equipped with a timer and humidistat for controlled operation, allowing for delayed start and humidity management, along with optional UV lighting and heating for curing and mold prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional air circulation systems are used during floor refinishing, then air circulation is provided, but the system cannot operate on a wet floor and may interfere with the curing process causing skinning issues
Solution Approach 1:
The fan unit is suspended from the ceiling (vertical dimension) rather than being placed on the floor (horizontal dimension), allowing air circulation without contact with the wet floor surface. This dimensional change enables operation during floor refinishing without compromising the curing process.
2Productivity
If fans are positioned on the wet floor to speed the curing process, then air circulation speed is increased, but the fan cannot be safely positioned on the wet surface
Solution Approach 1:
The fan unit operates from the ceiling dimension rather than the floor dimension, providing air circulation to accelerate curing without requiring placement on the wet floor surface, thus ensuring safety while maintaining productivity.
Solution Approach 2:
The fan unit is pre-configured with suspension capabilities and control systems before deployment, allowing it to be safely installed and operated from the ceiling without requiring floor contact during the refinishing process.
3Productivity
If air circulation is provided immediately after solvent application, then drying speed is increased, but skinning occurs on the refinishing material
Solution Approach 1:
The fan unit incorporates a timer or control system that delays the start of air circulation until the refinishing material has initially set, preventing skinning while subsequently accelerating the drying process without compromising surface finish quality.
Solution Approach 2:
The air circulation operates in controlled periodic cycles rather than continuously, allowing intervals for the refinishing material to set without air disturbance, then providing circulation to accelerate drying, thereby preventing skinning while maintaining drying speed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe and efficient air circulation above a floor surface without additional equipment, preventing skinning and promoting effective curing while managing humidity and mold/mildew, suitable for high-humidity areas like basements and recreational vehicles.
Implementation Method 1
Air circulation systems, such as fan units are commonly utilized for ventilation, assistance with climate and humidity control
Implementation Method 2
a timer and a humidistat connectable to corresponding electrical outlets of the at least two electrical outlets of the outlet tap for selectively controlling operation of the fan

AI summary
An air circulation system includes an outlet tap having a pair of prong outlets receivable by a corresponding pair of electrical outlets of an electrical receptacle mounted to a vertical wall and positioned near a support surface, the outlet tap having at least two electrical outlets opposite the pair of prong outlets for providing electrical power from one or both of the electrical outlets of the electrical receptacle. A support member operatively connected to the outlet tap, the support member is adapted to suspendedly support a fan vertically above the support surface in response to the outlet tap being received by the electrical receptacle. A timer and a humidistat are connectable to corresponding electrical outlets of the at least two electrical outlets of the outlet tap for selectively controlling operation of the fan.
