Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cleaning vehicle or building exteriors are physically demanding, require manual scrubbing, and are difficult for high-profile vehicles without ladders, and cannot simultaneously rinse and scrub.
Innovation Solution
A pressure washer wand cleaning attachment with a roller assembly and bristled head that spins due to water pressure, allowing simultaneous application of water and soap, and can be attached to any standard pressure washer wand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual scrubbing with sponge or brush is used, then cleaning can be performed, but it is physically demanding and difficult for high-profile vehicles
Solution Approach 1:
The patent combines the rinsing function and scrubbing function into a single integrated operation. The roller assembly with bristles is positioned to contact the surface simultaneously as water is sprayed, allowing rinsing and scrubbing to occur at the same time rather than sequentially. This merging of functions eliminates the need for separate rinsing and scrubbing steps, reducing both physical effort and time required for cleaning.
Solution Approach 2:
The roller assembly is designed to be self-propelling through the force of water pressure alone. As water sprays onto the bristles, it automatically causes the roller to rotate and move across the surface without requiring manual scrubbing motions. This self-service mechanism eliminates the physically demanding repetitive scrubbing motion while maintaining effective cleaning action.
2Ease of operation
If traditional sponge or brush is used, then soap can be applied, but manual scrubbing is required which is physically demanding
Solution Approach 1:
The roller assembly serves multiple functions simultaneously: it acts as a soap application surface, a scrubbing brush, and a rinsing mechanism. Soap is applied to the bristles of the roller, which then contacts the surface to scrub and clean. The same roller is simultaneously rinsed by the water spray. This multi-functionality eliminates the need for separate soap application tools and scrubbing brushes, reducing device complexity while improving ease of operation.
3Adaptability or versatility
If ladder or step stool is used to reach high areas, then high-profile vehicles can be cleaned, but it introduces safety risks and complexity
Solution Approach 1:
The water spray acts as an intermediary that transmits the cleaning action from the ground level to high surfaces. The roller assembly, propelled by water pressure, can reach and clean high areas of vehicles without requiring the operator to physically elevate themselves. This intermediary mechanism allows safe and easy cleaning of high-profile vehicles while maintaining effectiveness on elevated surfaces.
