Extendable Bathing Applicator With Elastic Reach and Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shower puffs and back scrubbers have limited reach, making it difficult for users, especially elderly, larger, or inflexible individuals to clean their back and other hard-to-reach areas, and often require rigid handles that are cumbersome and obstructive.
Innovation Solution
An extendable bathing device with an elastic band surrounded by scrubbing materials, such as open cell mesh or loofah, and a retractable cable assembly with a locking mechanism, allowing for increased reach and ease of use, while also facilitating the application of lotions and other substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a rigid elongated handle is used to increase reach, then the effective reach of the user is improved, but the device becomes cumbersome and obstructive in the shower
Solution Approach 1:
The patent applies the dynamics principle by using an elastic band instead of a rigid handle. The elastic band can dynamically extend to provide reach when needed and automatically retract to a compact form for easy storage and transport. This dynamic behavior resolves the contradiction between needing long reach and maintaining ease of operation.
Solution Approach 2:
The patent implements nesting by allowing the elastic band to retract and compact into a small form factor when not in use. The extendable structure can be nested within a compact configuration, enabling the device to transition between extended operational state and compact storage state, thus resolving the contradiction between reach and portability.
2Length of moving object
If a rigid elongated handle is used to increase reach, then the effective reach of the user is improved, but the device obstructs the already crowded shower or bath
Solution Approach 1:
The elastic band provides dynamic length adjustment, extending only when the user needs to reach distant areas and retracting when not in use. This dynamic behavior reduces the average space occupation in the shower while maintaining the capability for extended reach when needed, resolving the contradiction between reach and space occupation.
Solution Approach 2:
The patent applies local quality by providing extendability only at the specific location where reach is needed (the band itself), while the rest of the device remains compact. This localized extension capability allows reach improvement without proportionally increasing the overall space occupation of the device.
3Ease of operation
If conventional shower puffs are used, then the device is compact and easy to store, but the ability to reach parts of the body is limited
Solution Approach 1:
The elastic band structure allows the device to dynamically transition between a compact stored state and an extended operational state. When stored, the band is compact like traditional shower puffs; when in use, it extends to provide enhanced reach, thus resolving the contradiction between storage ease and reach capability.

AI summary
An extendable applicator device which allows a user to apply soap, lotion, medication, or various other substances to areas of the body which may be difficult to reach. The device can function as a traditional scrubbing or application device but may also be extended so that the user's back, shoulders, or other areas can be addressed as well. Exemplary embodiments use an elastic member that can elongate to allow an extended reach. Other embodiments use a locking mechanism or a retracting assembly to allow the device to extend.
