Portable Scrubbing Wheel With Pivoting Elements for Continuous Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning devices with rotary brushes face resistance when encountering treatment surfaces, preventing effective rotation and making it difficult to deliver treatment materials simultaneously without stopping the cleaning process.
Innovation Solution
A portable scrubbing apparatus with a rotatable wheel and nozzle system that allows fluid to be directed at the wheel for rotation, while scrubbing elements pivot to maintain contact with the surface and include a dispensing system to apply treatment material as needed, ensuring continuous cleaning and efficient material delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a rotary brush is propelled by fluid delivered through the device, then the brush can rotate and clean the surface, but resistance is encountered when other portions of the brush are positioned against the treatment surface, preventing effective rotation
Solution Approach 1:
The scrubbing elements are designed to pivot dynamically between a radial orientation during fluid-driven rotation and a contact orientation when engaging the treatment surface. This dynamic adjustment allows the brush to maintain rotation while effectively contacting the surface for cleaning.
Solution Approach 2:
The brush is segmented into multiple independent scrubbing elements that can pivot individually. This segmentation allows different portions of the brush to perform different functions simultaneously - some elements rotate with the fluid flow while others contact the surface, reducing overall resistance.
2Productivity
If treatment material is delivered to the surface being cleaned, then the cleaning effectiveness is improved, but it is difficult to deliver the treatment material at the desired time and in the desired amount without stopping cleaning
Solution Approach 1:
The treatment material delivery system is merged with the rotating brush assembly. The dispenser is positioned to receive treatment material onto the scrubbing elements during rotation, combining the cleaning and treatment application functions into a single integrated operation that continues without stopping.
Solution Approach 2:
Treatment material is applied to the scrubbing elements in advance of their contact with the treatment surface. The dispenser delivers material onto the rotating brush elements, which then carry the material to the surface during their rotational path, ensuring material is ready for immediate application without interrupting cleaning.

AI summary
A portable cleaning apparatus includes a handle and a wheel rotatably mounted to the handle having a plurality of scrubbing elements. A nozzle delivers fluid to the scrubbing elements to effect rotation of the wheel. The scrubbing elements can be secured to the wheel to limit pivoting movement of the scrubbing element in a direction of rotation of the wheel while permitting greater pivoting movement of the scrubbing elements in a direction opposite the direction of rotation of the wheel. A dispensing system mounted to the handle is remotely operable to position a dispenser of treatment material in the rotational path of the scrubbing elements to apply treatment material to the scrubbing elements.
