Wall-Mounted Back Scrubber with Suction-Based Soap Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing back scrubbing devices lack stability and durability, often becoming dislodged during use due to flimsy mounting mechanisms and are cumbersome to maneuver, especially when used for thorough scrubbing of large areas.
Innovation Solution
A mountable back scrubbing device with a base, dispenser, and a dispensing frame that includes a central vein and lateral veins for soap distribution, nubs for scrubbing, and a mounting mat with suction cups for secure attachment, allowing for stable and efficient soap dispensing and scrubbing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the back scrubbing device is made large enough to scrub the entire back and body, then the scrubbing coverage is improved, but the device becomes bulky and cumbersome to move
Solution Approach 1:
The device is divided into a stationary mounting base and a separable handheld scrubbing component. The base remains fixed to provide stable soap dispensing and scrubbing surface, while the handheld portion can be easily moved and repositioned by the user to access different areas of the back and body.
2Reliability
If the mounting mechanism is made stronger to withstand prolonged and vigorous use, then the stability and reliability are improved, but the device complexity increases
Solution Approach 1:
The mechanical mounting mechanism is replaced with suction cups that utilize vacuum pressure and adhesion forces to attach the device to the shower wall. This eliminates complex mechanical fasteners, screws, or clips while providing strong, reliable mounting that withstands vigorous use and humid bathroom environments.
3Ease of operation
If the device is made stationary and mounted on the wall, then the ease of scrubbing is improved, but the mounting mechanism becomes flimsy and does not remain mounted for extended periods
Solution Approach 1:
The device uses suction cups with vacuum adhesion technology instead of mechanical mounting systems. The suction cups create a strong seal against the shower wall, utilizing atmospheric pressure to hold the device firmly in place during extended use, preventing it from becoming dislodged or appearing flimsy.
4Productivity
If the veins and nubs are used to distribute liquid soap throughout the dispenser, then the soap distribution efficiency is improved, but the risk of leakage increases
Solution Approach 1:
The veins and nubs are constructed from flexible material that can deform to control soap flow. The flexible structure allows the veins to distribute soap efficiently through their channels while the material's elasticity prevents leakage by conforming to pressure changes and maintaining sealed connections at the soap reservoir interface.
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 provides stable, thorough, and efficient scrubbing of hard-to-reach areas by securely attaching to a surface, ensuring prolonged use and effective soap distribution without leakage, even in humid environments.
Implementation Method 1
a mounting mat on the bottom surface of the base, where the mounting mat secures the mountable back scrubbing device against a flat surface
