Foot cleaning device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foot cleaning devices do not effectively clean the bottom of the foot or heel simultaneously with other portions of the foot or leg.
Innovation Solution
A foot cleaning device featuring a T-shaped frame with interconnected rollers and sheet rolls, allowing for simultaneous cleaning of the top and bottom of the foot, with a third roller connected to the frame to facilitate rotation of the interconnected rollers, enabling effective cleaning and massage of the foot and heel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single roller or simple roller arrangement is used, then the device structure is simple, but it cannot clean the bottom of the foot or heel simultaneously with other portions of the foot or leg
Solution Approach 1:
The foot cleaning device is divided into multiple independent roller units (first roller, second roller, third roller, fourth roller) that can be separately positioned and configured. Each roller can contact different portions of the foot, allowing simultaneous cleaning of multiple areas including the bottom of the foot, heel, and other portions without requiring a single complex roller structure.
Solution Approach 2:
The device transitions from a single-plane roller arrangement to a multi-dimensional configuration where rollers are positioned at different heights and angles. The third and fourth rollers are arranged at different vertical levels than the first and second rollers, creating a three-dimensional cleaning surface that can accommodate the contours of the foot, heel, and ankle simultaneously.
2Adaptability or versatility
If multiple spaced-apart rollers are used to clean different portions of the foot, then cleaning coverage is improved, but the rollers cannot rotate together to provide effective cleaning action
Solution Approach 1:
The first, second, third, and fourth rollers are connected through a common drive mechanism that includes a drive shaft, belt, and pulley system. This merging of the rollers into a synchronized system ensures that when one roller rotates, all other rollers rotate simultaneously, providing coordinated cleaning action across multiple foot areas including the heel and bottom of the foot.
Solution Approach 2:
A belt acts as an intermediary element that transfers rotational motion from the drive shaft to multiple pulleys mounted on different rollers. This intermediary mechanism ensures synchronized rotation of all rollers while allowing them to remain spaced apart to contact different portions of the foot and heel simultaneously.
3Adaptability or versatility
If the foot is placed between spaced-apart rollers, then the bottom of the foot can be cleaned, but the heel and other portions cannot be cleaned simultaneously
Solution Approach 1:
The device utilizes vertical and angular dimensions in addition to horizontal spacing. The third and fourth rollers are positioned at different vertical levels, allowing the foot to be cradled in a three-dimensional arrangement where the heel contacts lower rollers while the midfoot and forefoot contact upper rollers, achieving comprehensive coverage without excessive device length.
Solution Approach 2:
The multiple rollers are arranged in a nested configuration where the foot passes through and contacts rollers at different levels and positions. The first and second rollers are positioned to contact the bottom of the foot, while the third and fourth rollers contact the heel and ankle areas, creating a nested cleaning path that maximizes coverage within a compact device footprint.
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
The device allows for comprehensive cleaning and massage of the foot, including the bottom and heel, by rotating the interconnected rollers when the foot is placed in specific positions, ensuring thorough cleaning and comfort.
Implementation Method 1
The first sheet roll abutting each of the first and second rollers... rotation of the third roller causes rotation of the plurality of interconnected rollers

AI summary
A cleaning device includes at least one T-shaped frame and a first sheet roll surrounding an internal space. The T-shaped frame abuts the internal space. First and second rollers are spaced apart from each other within the internal space and are disposed at opposite first and second ends of the at least one T-shaped frame, such that the first sheet roll abuts each of the first and second rollers. A third roller, exterior to, and spaced apart from, the first sheet roll, rotatably attached to the at least one T-shaped frame at a third end thereof.
