Arrangement with a round brush
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foot washing devices are not suitable for individuals with physical disabilities, and they often cause excessive stress on the brush and limit accessibility to hard-to-reach areas of the foot.
Innovation Solution
A rotary-driven round brush mounted on a support with a U-shaped bracket, allowing easy access from multiple angles, and a water-driven motor with a slip clutch for safety, integrated with a container for soap and disinfectant, and a pedal-operated shut-off valve for convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the round brush is mounted to project freely from the wall without additional components, then the device complexity is reduced, but the accessibility to hard-to-reach areas of the foot (toes, instep, heel) is limited
Solution Approach 1:
The device is segmented into functional zones: the round brush for general cleaning, the bracket with opening for toe and instep access, and the support structure for heel access. This segmentation allows each component to address specific hard-to-reach areas while maintaining overall system simplicity
Solution Approach 2:
The bracket introduces a new spatial dimension by creating an opening that allows the brush to access the toes and instep from above, while the support structure provides access from below. This multi-dimensional approach enables comprehensive foot cleaning without adding complex mechanisms
2Ease of operation
If the round brush is positioned to allow access to toes and instep, then the accessibility is improved, but excessive stress is placed on the brush itself
Solution Approach 1:
The bracket acts as an intermediary structure that supports the foot during cleaning. By providing a platform for the foot to rest on, the bracket bears the mechanical stress instead of transferring it directly to the round brush, thereby protecting the brush while enabling access to difficult-to-reach areas
3Ease of manufacture
If the round brush is driven by a hydraulic motor with water exiting laterally through openings, then the ease of manufacture is improved, but the water supply to the brush is insufficient
Solution Approach 1:
The hollow shaft is nested within the motor housing, with water supply channels integrated into the shaft structure. Water is supplied through the hollow shaft and distributed radially through openings in the shaft wall, ensuring reliable water supply to the brush while maintaining a compact, easily manufactured design

AI summary
The invention relates to an arrangement (1) for cleaning floors having a round brush (2) driven in rotation. The rotary drive (12), operated with water, is arranged on a carrier (3) formed as a housing (4). Water exits in the region of the shaft of the round brush (2) from the rotary drive (12) to the round brush (2). A U-shaped bracket (7) is secured to the housing (4) and is arranged above the round brush (2) such that the upper region of the round brush (2) protrudes through the bracket (7). The supply of water to the rotary drive (12) is controlled by a shut-off valve (3) which is actuated with the aid of a pedal (31). The pedal (31) is arranged between a foot part (11) of the housing (4) and the round brush (2).
