Modular Bathing Aid Assembly for Safe Back and Foot Scrubbing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bathing aids are inconvenient and unsafe for users, particularly elderly, children, and handicapped individuals, as they require users to raise their legs to clean their feet, leading to potential slips and falls, and often lack a sufficient scrubbing area for effective body cleaning.
Innovation Solution
A bathing aid comprising a base with a scrubbing member, fastener, and binding member, detachably fixed to a surface, allowing users to move their back or feet safely while providing a larger scrubbing area by connecting multiple units, which can also serve as a pillow or back pad for a bathtub.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional bathing aid (bathing ball or sponge) is used, then the user can clean their body, but the user must hold it tightly in hand which is inconvenient for cleaning back and feet, and may cause foot slip or body fall
Solution Approach 1:
The bathing aid is divided into multiple detachable modules (first bathing aid module, second bathing aid module, etc.) that can be separately positioned and used. Each module can be independently fixed to the bathtub surface, allowing users to clean different body parts (back, feet, etc.) without needing to hold the bathing aid, thereby improving both convenience and safety.
Solution Approach 2:
The bathing aid modules are designed to be fixed to the bathtub surface using suction cups, enabling the bathing aid to serve itself by maintaining its position without user intervention. Users can simply move their bodies to access different cleaning areas rather than needing to manually position or hold the bathing aid.
2Ease of operation
If an elongated handle with bathing ball or sponge is used, then the user can clean their back conveniently, but the user still needs to raise their leg for cleaning feet which is inconvenient and unsafe
Solution Approach 1:
The bathing aid system is segmented into multiple functional modules that can be positioned at different locations on the bathtub surface. This includes modules for back cleaning and modules for foot cleaning, allowing users to access both functions without needing to raise their legs or reposition themselves significantly.
Solution Approach 2:
The bathing aid system is designed with multi-functional modules that can serve different cleaning purposes (back cleaning, foot cleaning, etc.). Each module can be independently used or combined with others, providing universal applicability for various body parts without requiring the user to raise their legs.
3Adaptability or versatility
If a fixed-size bathroom accessory with projections is used, then it can be detachably fixed on wall for cleaning back, but it cannot provide appropriate scrubbing area to meet user's actual need and projections deteriorate comfort
Solution Approach 1:
The bathing aid is divided into multiple detachable modules with different sizes and functions. Users can select and combine modules based on their specific cleaning needs, providing customizable scrubbing areas without the discomfort of fixed-size designs with protruding elements.
Solution Approach 2:
Different modules are designed with different local characteristics suitable for specific body parts. For example, some modules may have softer surfaces for sensitive areas while others have more robust scrubbing surfaces for tougher areas, all without requiring protruding projections that would deteriorate comfort.
4Adaptability or versatility
If a modular system with spaced projections is used, then the scrubbing area can be enlarged by connecting additional modules, but the projections deteriorate comfort and suction cup connection is insufficient
Solution Approach 1:
The modular bathing aid system is segmented into multiple detachable units that can be connected to expand the scrubbing area. Each module maintains a smooth surface design without protruding projections, ensuring comfort is preserved even when multiple modules are combined for larger coverage areas.
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
Enables safe and convenient cleaning of the back and feet without the risk of falls, with the ability to expand or reduce the scrubbing area as needed, providing enhanced comfort and support during bathing.
Implementation Method 1
a fastener mounted to a bottom side of the base for fastening the base to a surface of an object detachably

AI summary
A bathing aid includes a base, a scrubbing member mounted to a top side of the base, a fastener mounted to a bottom side of the base for detachably fastening the base to a surface of an object, and a binding member for binding the scrubbing member and the fastener to the base. The base has a positioning portion and a connecting part. The scrubbing member is partially received in the positioning portion. The connecting part is detachably coupled with the base of another same bathing aid to substantially expand the scrubbing area for body cleaning. In this way, the bathing aid can not only be fixed to a wall or the ground for the user to conveniently clean his or her back or feet but expand the area for contact the user's body or serve as a pillow for the user to lie on.
