Curved Trajectory Wheel Brush Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wheel washing devices often fail to achieve optimal cleaning results due to the brush device's inability to accurately align with the wheel axis, especially for vehicles with varying wheel diameters and widths, leading to incomplete coverage and reduced cleaning effectiveness.
Innovation Solution
The wheel washing device features an infeed device that moves the brush device along a trajectory with at least one turning point, allowing for adjustable positioning to align closely with the wheel axis, regardless of vehicle width and wheel diameter, ensuring better coverage and cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the brush device is lowered along a straight inclined plane, then the structure is simple, but the alignment accuracy with the wheel axis deteriorates for vehicles with varying wheel diameters
Solution Approach 1:
The infeed trajectory is designed as a curved path with at least one turning point instead of a straight inclined plane. This curvature allows the brush device to follow an optimized path that improves alignment accuracy with the wheel axis for vehicles with varying wheel diameters and widths, resolving the contradiction between structural simplicity and alignment precision.
2Measurement precision
If the brush device follows a curved trajectory with turning points, then the alignment accuracy with the wheel axis is improved, but the device complexity increases
Solution Approach 1:
The infeed device is designed with dynamic adjustment capabilities that allow the trajectory to be automatically adapted based on the detected wheel position and vehicle dimensions. This dynamic approach enables the system to achieve high alignment accuracy without requiring complex manual configuration or multiple fixed trajectories for different vehicle types.
Solution Approach 2:
The system incorporates feedback mechanisms that detect the wheel position and vehicle characteristics, then automatically adjust the infeed trajectory parameters. This feedback loop enables the brush device to follow the optimal curved path with turning points while keeping the control system complexity manageable through automated adjustment rather than manual configuration.
