Segmented Brush for Variable Wheel Cleaning Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wheel cleaning systems fail to effectively clean vehicle wheels due to constant pressure application, which is inadequate for irregular surfaces and varying distances from the axis of rotation, and require replacement of entire brushes even if only a small segment is damaged.
Innovation Solution
A wheel cleaning system with a brush assembly comprising multiple cleaning elements that cyclically change length and contact pressure, mounted on a shaft rotating about a longitudinal axis, allowing for varying radial distances and phased positioning to engage wheel surfaces effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cylindrical brush with constant bristle length is used, then the brush structure is simple and easy to manufacture, but it applies constant pressure to the wheel which is inadequate for irregular surfaces and varying distances from the axis of rotation
Solution Approach 1:
The brush is divided into multiple segments with different bristle lengths arranged in a non-uniform pattern around the circumference. This allows different portions of the brush to adapt to different distances from the axis of rotation and various wheel surface irregularities, while maintaining a relatively simple overall cylindrical structure that is easy to manufacture.
2Device complexity
If the entire brush is replaced when a small segment is damaged, then the brush structure is simple and contiguous, but it results in unnecessary replacement and increased cost
Solution Approach 1:
The brush is divided into multiple replaceable segments that can be independently removed and replaced. This segmentation allows only the damaged segment to be replaced rather than the entire brush, reducing material waste and cost while maintaining the contiguous appearance and functionality of the overall brush structure during operation.
3Ease of operation
If constant pressure is applied by the brush, then the brush structure and operation are simple, but it fails to provide optimum cleaning for wheels with varying surface distances from the axis of rotation
Solution Approach 1:
The brush segments are designed with different bristle lengths that dynamically adapt to varying distances from the axis of rotation as the brush rotates. This creates variable contact pressure across different portions of the wheel surface, optimizing cleaning performance for irregular surfaces while maintaining relatively simple brush operation without complex control mechanisms.

AI summary
Methods, systems and apparatuses for are disclosed for cleaning a vehicle wheel surface on a vehicle wheel with a brush. A brush may comprise a plurality of resilient brush elements having varying lengths. The methods may provide for rotating the brush elements such that at any time during at least some of the plurality of brush elements are in engagement with the wheel surface. The wheel surface may be engaged by brush elements that have a length that changes cyclically and the brush elements may also cyclically vary the contact pressure between brush elements and the vehicle surface.
