Solution Overview
Problem
Existing body washing machines do not effectively address the challenge of cleaning the back and shoulders, which are typically difficult to reach and maintain proper hygiene, leading to potential skin damage and acne.
Innovation Solution
A back and shoulder washing machine with extendable spinning brushes that attach to a shower wall, featuring a swiveling motion and a refillable soap reservoir, connected to the shower head water supply for efficient and comfortable cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a person uses a hand-operated scrubbing tool to clean their back and shoulders, then they can maintain some level of hygiene, but it is difficult to reach and strain the user, reducing ease of operation
Solution Approach 1:
The device allows a person to wash their own back and shoulders automatically through motorized brush rotation and extension, eliminating the need for manual scrubbing actions that cause strain while maintaining hygiene effectiveness
Solution Approach 2:
The patent replaces manual mechanical scrubbing with an automated motorized system that rotates and extends brushes to clean the back, substituting human physical effort with mechanical automation to reduce strain
2Productivity
If conventional shower devices are used to wash the back, then water can be applied, but they lack effective scrubbing capability, reducing cleaning effectiveness
Solution Approach 1:
The device combines water dispensing functionality with motorized brush scrubbing capabilities in a single integrated system, allowing simultaneous water application and mechanical cleaning to enhance overall cleaning effectiveness
Solution Approach 2:
The shower device performs multiple functions including water dispensing, soap application, and automated brush scrubbing, making it a multi-functional cleaning system that addresses various cleaning needs in one device
3Productivity
If fixed brushes are used in back washing devices, then the structure is simple, but they cannot effectively reach all areas of the back, reducing cleaning coverage
Solution Approach 1:
The patent employs dynamically adjustable brush extensions that can extend and retract based on cleaning needs, allowing the brushes to reach different areas of the back while maintaining a compact structure when not in use
Solution Approach 2:
The device adds the dimension of brush extension along the length of the back, allowing brushes to reach from the upper to lower back areas, effectively utilizing spatial dimension to improve coverage without proportionally increasing overall device complexity

AI summary
A back and shoulder cleansing machine for a shower wall is disclosed. The device mounts to the wall using suction cups and is connected to the shower head water supply for dispensing water and soap from the brush body. Additionally, the brush body rotates and also has a pair of elevated brushes extending from the main device. The elevated brushes are also configured to have a swiveling motion and are then used to wash a person's shoulders. Additionally, the main body includes a refillable soup revivor which is accessed from a top end of the main body. Excess water from within the main body is then dispensed from a release valve at the bottom end of the main body.
