C-Shaped Shield for Tire Brush Chemical Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tire brush systems in car washes suffer from inefficient chemical distribution, leading to waste and uneven coating, as well as clogging issues with sprayers and nozzles, resulting in significant chemical loss and safety hazards.
Innovation Solution
A c-shaped shield with through-ports and grooves is designed to attach to tire brushes, providing even chemical distribution and preventing spills by eliminating restrictive points in the chemical delivery line, while the shield's design captures and re-applies excess chemical, reducing wear on brushes and friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If sprayers or nozzles are used to spray chemical onto the brushes, then chemical can be applied to the tire brush, but the chemical is wasted and the applicators clog easily
Solution Approach 1:
The patent removes the restrictive nozzles and sprayers from the chemical delivery system. Instead of forcing chemical through small orifices, the system delivers chemical through open channels directly to the brush, eliminating the clogging issue and reducing chemical waste while maintaining effective chemical application.
Solution Approach 2:
The chemical delivery system is segmented into multiple distribution channels that deliver chemical to different sections of the brush independently. This segmentation allows chemical to be distributed evenly across the brush surface without requiring restrictive nozzles, thereby reducing chemical waste and preventing clogging.
2Quantity of substance
If sprayers or nozzles are used to spray chemical onto the brushes, then chemical can be applied to the tire brush, but the chemical does not distribute evenly along the brush
Solution Approach 1:
The chemical delivery system is divided into multiple distribution channels that independently deliver chemical to different sections of the brush. This segmentation ensures uniform chemical distribution across the entire brush surface, eliminating the uneven coating problem associated with sprayer systems.
Solution Approach 2:
Distribution channels act as intermediaries between the chemical source and the brush. These channels guide and evenly distribute chemical along the brush surface, ensuring uniform application without the restrictions and inconsistencies caused by nozzles and sprayers.
3Quantity of substance
If sprayers or nozzles are used to spray chemical onto the brushes, then chemical can be applied to the tire brush, but the chemical does not continuously stay on the brushes and drips off when not in use
Solution Approach 1:
The system dynamically adjusts chemical delivery based on brush operation. Chemical is continuously supplied to the brush during operation through open channels, and the system adapts to maintain chemical on the brush surface. When the brush is not in use, chemical delivery is adjusted to prevent excessive accumulation and dripping, improving reliability and reducing waste.
4Quantity of substance
If restrictive nozzles or pin hole manifolds are used for chemical delivery, then chemical can be sprayed onto the brush, but the system clogs due to the restrictive nature of the design
Solution Approach 1:
The patent extracts and removes the restrictive nozzles and pin hole manifolds from the chemical delivery system. By eliminating these restrictive components, the system achieves reliable chemical delivery without clogging, as chemical flows through open channels rather than being forced through small orifices that are prone to blockage.
Solution Approach 2:
Instead of forcing chemical through restrictive nozzles, the system inverts the approach by using open channels that allow chemical to flow freely to the brush. This inversion of the delivery mechanism eliminates the clogging problem inherent in restrictive nozzle designs while maintaining effective chemical application.

AI summary
A device for use in dispensing tire chemical onto a cylindrical car tire brush, comprising, an elongated shield having a concave inside surface having a curvature generally matching the outside curvature of the cylindrical brush, a port entering into the inside surface of the shield for receiving a chemical, and at least one distribution groove formed into the inside surface, which distribution groove communicates with the port and is inclined downwardly at an angle so as to distribute the chemical longitudinally along the said inside surface.
