HVAC Coil Brush With Articulating Handle And Segmented Bristles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleaning devices are inadequate for accessing and cleaning the evaporator coils of HVAC systems due to their geometry and tight spacing, failing to effectively remove debris from both the coil surface and between the fins.
Innovation Solution
A coil brush with adjustable bristle bundles and articulating handles that allow for various angles and access points, featuring straight, bent, or hook-shaped bristles, enabling efficient cleaning of hard-to-reach areas by adjusting stiffness and positioning for optimal debris removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional brushes (cat hair brush, pot brush, wire welding brush) are used to clean evaporator coils, then general cleaning can be performed, but they cannot access tight spaces and converging points due to their size and geometry
Solution Approach 1:
The brush head is divided into multiple bristle bundles arranged in a matrix pattern, with each bundle accessible from different directions. This segmentation allows the brush to clean both the coil surface and the spaces between fins effectively, resolving the contradiction between accessibility and cleaning effectiveness.
Solution Approach 2:
The brush design adds dimensional versatility by allowing access to bristle bundles from multiple directions (front, back, sides). This multi-dimensional access capability enables the brush to reach converging points and tight spaces while maintaining effective cleaning performance.
2Area of stationary object
If the brush head is made larger to clean more surface area, then cleaning coverage increases, but it cannot fit in tight spaces and converging points
Solution Approach 1:
The brush head is segmented into multiple bristle bundles arranged in a compact matrix. This segmentation provides a large total cleaning surface area while keeping the overall brush head size small enough to fit in tight spaces and converging points.
Solution Approach 2:
Different bristle bundles can be accessed from different directions, allowing the brush to adapt to local geometries of the coil. This local accessibility maintains large cleaning coverage while fitting constrained spaces.
3Productivity
If bristle stiffness is increased to improve debris removal capability, then cleaning effectiveness increases, but the brush cannot access tight spaces and may damage coil fins
Solution Approach 1:
The brush employs bristle bundles with varying stiffness characteristics suitable for different cleaning locations. Softer bundles can access tight spaces between fins, while stiffer bundles handle heavier debris on coil surfaces, resolving the contradiction between debris removal capability and accessibility.
Solution Approach 2:
The brush design allows for adjustable or variable bristle stiffness through different bundle configurations. This dynamic adaptation enables the brush to optimize its mechanical properties for both tight space access and effective debris removal.

AI summary
The present invention provides a coil brush having one or more brush heads with any brush head parallel to any other. The brush heads may have a head base, a bristle slide or guide, and bundles or groups of straight and/or angled bristles, which may be interspersed in different arrangements in a head base of the head brush head, allowing for a variety of brushing planes. The coil brush may further comprise a rear mount handle or a detachable handle that allow the user to adjust the position of the brush to better access and clean coils in hard to reach places. The bristle slide allows the user to control the stiffness of the bundles of bristles by controlling the spreading of the bristles. This invention allows the brushing of coils in heating ventilation and air conditioning equipment at a variety of angles from a variety of coil access points.
