Brush Construction with Multi-Angle Bristles for Spoked Wheel Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle washing brushes are ineffective in cleaning spoked wheels, as their bristles cannot reach the sides and inner parts of the spokes, leading to incomplete cleaning and high water and detergent consumption, and are costly to maintain.
Innovation Solution
A brush construction with a base plate supporting bristles that are tilted at various angles and directions, including both clockwise and anticlockwise, allowing for better penetration between the spokes and reducing the need for costly adapters by being compatible with existing systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional brushes with axially arranged bristles are used, then the brush structure is simple and compatible with existing systems, but the bristles cannot reach the sides and inner parts of spoked wheels, resulting in incomplete cleaning
Solution Approach 1:
The bristles are arranged with different tilts and directions in different local areas of the brush. Specifically, the brush includes bristles tilted radially outward, bristles tilted radially inward, and bristles tilted axially, creating locally optimized cleaning zones that can effectively reach all surfaces of spoked wheels including sides and inner parts
Solution Approach 2:
The brush is divided into multiple functional zones with different bristle configurations. The bristles are segmented into different tilt groups (radially outward, radially inward, axial) that work together to clean different portions of the wheel, allowing the single brush to perform multiple cleaning functions
2Productivity
If special brushes with multiple disks and independent rotation mechanisms are used, then cleaning effectiveness improves, but the device complexity and cost increase significantly
Solution Approach 1:
Multiple cleaning functions that previously required separate disks and independent rotation mechanisms are merged into a single brush structure. The combination of bristles with different tilts (radially outward, radially inward, and axial) within one brush enables comprehensive cleaning of spoked wheels without requiring complex multi-disk mechanisms
Solution Approach 2:
The brush is designed as a universal cleaning device that can effectively clean all types of wheels including spoked wheels. By incorporating bristles with multiple tilt directions and arrangements, the single brush structure performs the functions previously requiring specialized multi-disk brushes, reducing both complexity and cost
3Area of stationary object
If brushes with frustoconical shape are used, then the surface of action increases, but the bristles still cannot effectively reach the sides of the spokes
Solution Approach 1:
While maintaining the frustoconical shape for increased surface area, the invention adds locally optimized bristle arrangements with different tilts. The inclusion of radially inward tilted bristles and axially tilted bristles in specific zones enables these bristles to reach into the spaces between spokes and clean the sides and inner parts that were previously inaccessible
