Dual-Layer Sponge Roller for High-Capacity Low-Resistance Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning equipment, such as vacuum cleaners and manual tools, struggle to effectively remove waste and stains firmly attached to the ground, and thicker sponge rollers in new generation cleaners face challenges with water removal and energy efficiency due to excessive squeezing force required.
Innovation Solution
A sponge roller design comprising an outer absorbent layer and an inner non-absorbent layer, where the outer layer is thinner than the inner layer, allowing for efficient water storage and gentle squeezing without hindering rotation, and tapered ends for improved ground coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the sponge roller is made thicker to improve cleaning capability, then the cleaning capacity is improved, but more squeezing force is required to remove water which increases energy consumption
Solution Approach 1:
The sponge roller is segmented into multiple layers with different properties: an inner layer made of non-absorbent sponge and an outer layer made of absorbent sponge. This segmentation allows the roller to maintain thickness for cleaning capability while the outer layer specifically handles water absorption, reducing the force needed for water removal and thus lowering energy consumption during operation.
2Productivity
If the squeezing force is increased to remove water from the sponge roller, then water removal efficiency is improved, but the resistance to rolling increases which wastes energy
Solution Approach 1:
The sponge roller applies local quality by using an outer layer specifically designed with absorbent sponge material. This local differentiation means water absorption and removal functions are concentrated in the outer layer, allowing for more efficient water removal with less squeezing force applied to the entire roller, thereby reducing energy waste from excessive resistance during rolling.

AI summary
A sponge roller, a cleaning roller assembly, and a floor cleaner. The sponge roller includes an outer layer and an inner layer. The outer layer is sleeved on the inner layer; the inner layer is made of non-absorbent sponge, and the outer layer is made of absorbent sponge. The sponge roller can be made with a large thickness, thus improving the cleaning capacity of the cleaner. The water is mainly stored in the outer layer, so it can be squeezed out without the exertion of much more external force, and thus the resistance against the rotation of the sponge roller is negligible, thus saving the energy consumption.
