Dual-Layer Sponge Roller Design for Low-Resistance Floor Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional floor cleaners, including vacuum cleaners and manual tools, struggle to effectively remove waste and stains firmly attached to the ground, and the existing sponge rollers face challenges with water removal and energy efficiency due to the thickness and design of their sponge layers.
Innovation Solution
A sponge roller design featuring 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 conical ends that extend into the base shell for comprehensive cleaning.
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 the resistance during rotation increases and energy is wasted
Solution Approach 1:
The sponge roller is divided into two functional layers: an inner non-absorbent layer that maintains structural integrity and a thin outer absorbent layer that performs water absorption. This segmentation allows the roller to achieve effective cleaning without the excessive thickness that would cause high rotational resistance and energy waste.
Solution Approach 2:
Different regions of the sponge roller have different properties: the inner layer is made of non-absorbent sponge for structural support, while the outer layer is made of absorbent sponge for water absorption. This local differentiation optimizes both cleaning effectiveness and rotational efficiency without requiring the entire roller to be thick.
2Productivity
If a thick sponge roller is used to improve cleaning capability, then the cleaning capacity is improved, but the squeezing force required increases and water cannot be effectively removed
Solution Approach 1:
The sponge roller is segmented into an inner non-absorbent layer and an outer absorbent layer. The thin outer layer absorbs water during cleaning and allows for easy water removal through squeezing, while the inner layer provides structural support. This segmentation enables effective water removal without requiring a thick sponge structure.
Solution Approach 2:
The outer layer is specifically designed with absorbent properties for water uptake, while the inner layer has non-absorbent properties for structural integrity. This local quality differentiation ensures that water can be effectively removed from the outer layer without requiring excessive squeezing force on a thick structure.
3Quantity of substance
If the outer absorbent layer is made thicker to improve water absorption, then the water storage capacity is improved, but the resistance during rotation increases
Solution Approach 1:
The sponge roller structure segments the water absorption function into a thin outer layer, while the inner non-absorbent layer provides structural support. This segmentation achieves sufficient water storage capacity in the outer layer without the rotational resistance penalty of a thick overall structure.
Solution Approach 2:
The outer layer is locally optimized for water absorption with appropriate thickness, while the inner layer is optimized for structural support. This local quality differentiation maximizes water storage capacity in the functional outer layer while minimizing the rotational resistance that would result from a uniformly thick structure.

AI summary
A sponge roller (211), cleaning roller component (210), and floor cleaner. The sponge roller (211) comprises an inner sponge layer and an outer sponge layer, and the outer sponge layer is sleeved on the inner sponge layer. The inner sponge layer is made from non-absorbent sponge, and the outer sponge layer is made from absorbent sponge. Such sponge roller can be formed with a large thickness, and accordingly improves the cleaning effect of the cleaner. Since the portion absorbing water is primarily the outer sponge layer, water can be squeezed out of the roller without using an excessive force; thus no excessive obstruction to the sponge roller is formed, and unnecessary energy consumption is prevented.
