Side Brush Mechanism With Adjustable Skew for Vehicle Corner Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tunnel type car washing machines have suboptimal cleaning effects due to complex side brush structures and high manufacturing costs, often leaving residues on vehicles with large skew angles and corners, necessitating supplementary cleaning with additional brush assemblies that result in functional waste and increased costs.
Innovation Solution
A side brush mechanism with a novel structure featuring a side brush mounting beam, a swing arm connected to a reducer, a left-right skew actuator, and a rocker arm actuator, allowing for adjustable brushing angles and extended reach to clean large-angle windows and vehicle corners, along with proximity switches for position detection and a limit block to prevent over-stroke, enhancing cleaning efficiency and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex side brush structure with multiple actuators is used to achieve adjustable brushing angles and extended reach, then cleaning effectiveness is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The side brush assembly is divided into multiple independently controllable modules: a swing arm mechanism for horizontal movement, a skew mechanism for vertical adjustment, and a rotation mechanism for brushing action. Each module has its own actuator, allowing selective activation based on cleaning needs, thereby improving adaptability while managing complexity through functional segmentation
Solution Approach 2:
The side brush structure employs dynamic positioning capabilities with multiple degrees of freedom, allowing real-time adjustment of brushing angle and position through coordinated actuators. This dynamic adaptability enables the brush to conform to various vehicle shapes and cleaning requirements, significantly improving cleaning effectiveness without requiring an overly complex fixed structure
2Adaptability or versatility
If additional brush assemblies are installed for supplementary cleaning of corners and large skew angle windows, then cleaning coverage is improved, but manufacturing cost and functional waste increase
Solution Approach 1:
The side brush assembly is designed as a multi-functional unit capable of performing both primary cleaning and supplementary cleaning tasks. Through coordinated activation of the swing arm, skew mechanism, and rotation mechanism, a single assembly can clean standard surfaces, large skew angle windows, and vehicle corners, eliminating the need for separate supplementary brush assemblies and reducing manufacturing costs
3Adaptability or versatility
If the side brush assembly is extended to reach vehicle corners, then cleaning coverage is improved, but the risk of actuator over-stroke and component damage increases
Solution Approach 1:
The system incorporates sensors that detect the position of the side brush assembly and provide feedback to the control system. When the brush reaches its extended position or detects potential over-stroke conditions, the sensors trigger the control system to stop actuator movement, preventing component damage and extending service life while maintaining the ability to reach vehicle corners
