Automated Back Scrubber with Rotating Brushes and Soap Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing back scrubbers for showers lack an efficient and hygienic mechanism for cleaning the back of a patient, as they do not effectively distribute soap uniformly and require manual operation, which can be tiring and inefficient.
Innovation Solution
A back scrubber device with a housing that removably attaches to a vertical surface, containing a control circuit and soap reservoir, which uses rotating brushes to distribute soap through a manifold structure, providing motive force for rotation and soap distribution via a pump and brush motors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual operation is used for back scrubbing, then device complexity is reduced, but productivity and cleaning efficiency deteriorate
Solution Approach 1:
The back scrubber device is designed to perform cleaning functions automatically without requiring manual scrubbing operations. The device attaches to the patient's back and autonomously executes the cleaning process through integrated motors, brushes, and soap distribution systems, thereby improving productivity while maintaining reasonable device complexity
Solution Approach 2:
Manual mechanical scrubbing actions are replaced with an automated mechanical system comprising electric motors that rotate brushes and a pump that distributes soap. This substitution eliminates the need for manual operation while significantly enhancing cleaning efficiency and productivity
2Device complexity
If soap is not distributed uniformly, then device complexity is reduced, but manufacturing precision and cleaning quality deteriorate
Solution Approach 1:
The soap distribution system is segmented into multiple outlets or nozzles positioned across the brush assembly, allowing soap to be delivered uniformly across different zones of the back. This segmentation ensures even distribution without requiring overly complex pumping or control mechanisms
Solution Approach 2:
A manifold or distribution channel acts as an intermediary between the soap reservoir and the brush surfaces, evenly channeling soap to multiple contact points. This intermediary structure simplifies the overall system while achieving uniform soap distribution across the cleaning area
3Productivity
If automated soap distribution is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
A simple pump mechanism, operating on basic hydraulic principles, is used to distribute soap automatically. This pump can be driven by a small motor and delivers soap through gravity-assisted flow to the brushes, achieving automated operation without requiring complex control systems or multiple moving parts
Solution Approach 2:
The pump and soap distribution system is integrated with the existing brush motor and housing structure, serving multiple functions simultaneously: storing soap, pumping it under pressure, and distributing it through the brush assembly. This multi-functionality reduces overall device complexity while maintaining high productivity
