Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing back washing devices either use hardened scrubbers that are uncomfortable or soft towels that lose shape and require awkward movements to clean the entire back effectively.
Innovation Solution
A back and body washing device with a central portion made of soft cotton terrycloth and interfacing material to maintain shape during use, featuring handle sections for easy maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If soft towels are used for back washing, then comfort is improved, but shape stability deteriorates causing the towel to fold and lose shape
Solution Approach 1:
The back washing device combines soft cotton terrycloth material with a rigid structural core, creating a composite structure that provides both comfort through the soft outer material and shape stability through the rigid internal support, preventing the towel from folding or losing shape during use
Solution Approach 2:
Different parts of the device have different properties: the outer surface uses soft cotton terrycloth for comfort against the skin, while the internal structure uses rigid material for shape stability, allowing each region to perform its specific function optimally
2Object-affected harmful factors
If soft towels are used for back washing, then comfort is improved, but cleaning effectiveness worsens due to awkward movements required
Solution Approach 1:
The composite structure of soft outer material with rigid internal support allows the towel to maintain its shape and position on the back, enabling effective cleaning without requiring awkward body contortions, thus improving cleaning effectiveness while maintaining comfort
Solution Approach 2:
The device is designed to be flexible enough to conform to the back's surface while maintaining sufficient structural integrity to stay in position, allowing natural body movements to be used effectively for cleaning without requiring awkward contortions
