Reverse Rotation Side Washer With Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle wash systems are inadequate in cleaning certain areas, such as vehicle sides and wheels, due to non-reverse rotation side washers that can damage the vehicle and have maintenance issues with cloth attachment cores and hubs.
Innovation Solution
A reverse rotation side washer system with a retractable angled primary arm and secondary arm, using a stack of horizontal cloth brush panels that rotate in the opposite direction of vehicle travel, along with a shaft assembly and shock/spring assemblies to prevent damage and facilitate easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If non-reverse rotation side washers are used, then the system is simple to implement, but cleaning efficacy is insufficient and vehicle damage may occur
Solution Approach 1:
The patent applies reverse rotation to the side washer brushes, making them rotate in the opposite direction of conventional systems. This inversion allows the brushes to naturally retract away from the vehicle during rotation, preventing damage while effectively cleaning hard-to-reach areas like wheel wells and side panels that conventional forward-rotating brushes cannot access
2Device complexity
If conventional cloth attachment cores and hubs are used, then the initial structure is simple, but maintenance becomes difficult over time
Solution Approach 1:
The patent segments the cloth attachment system into modular components including the core, hub, and removable cloth elements. This segmentation allows individual components to be easily replaced without replacing the entire assembly, significantly reducing maintenance time and cost while improving ease of repair
Solution Approach 2:
The patent incorporates wear compensators that automatically adjust parameters such as brush pressure and cloth tension as components wear over time. This parameter adjustment maintains optimal cleaning performance and extends the service life of the system without requiring frequent complete replacements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively cleans hard-to-reach areas without damaging the vehicle and simplifies the replacement and maintenance of cloth materials by allowing for gentle, safe cleaning and easy retrofitting of conventional systems.
Implementation Method 1
at least one shock and spring assembly positioned between the retractable angled primary arm and the floor mount, and between the retractable secondary arm and the retractable angled primary arm

AI summary
Embodiments include a vehicle side washer assembly, a shaft assembly, and horizontal cloth brush panels. The side washer assembly includes a retractable angled primary arm, a retractable secondary arm, a shaft assembly having an upright shaft, and horizontal cloth brush panels. The upright shaft is disposed through a shaft attachment region of each of the horizontal cloth brush panels. The shaft assembly includes an upright shaft including notches and protrusions, and retrofit discs each including a shaft opening that matches contours of the upright shaft. Each of the retrofit discs includes rotary notches. The horizontal cloth brush panels each include flat fingers, a contiguous central region, and a brush shaft opening cut to match contours of the upright shaft. The horizontal cloth brush panels rotate in a reverse rotation with a direction of travel of a vehicle, and can be mixed and matches with various sizes and shapes.
