Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional floor cleaners, including vacuum cleaners, struggle to effectively remove waste and stains firmly attached to the ground due to limitations in their working principles, and existing sponge roller cleaners face challenges with water removal and energy efficiency.
Innovation Solution
A sponge roller assembly with an outer absorbent layer and an inner non-absorbent layer, where the outer layer is thinner than the inner layer, and both layers have tapered surfaces, allowing for efficient water storage and gentle water squeezing without hindering rotation, integrated with a power unit and sleeve barrel for enhanced cleaning capabilities.
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 energy is consumed and water removal becomes more difficult
Solution Approach 1:
The sponge roller is divided into multiple layers with different functions: the inner layer (first sponge layer) provides structural support and basic cleaning, while the outer layer (second sponge layer) is optimized for water absorption and release. This segmentation allows each layer to be optimized independently, reducing the total thickness needed while maintaining cleaning capacity and improving water management efficiency.
Solution Approach 2:
Different regions of the sponge roller have different properties: the inner layer has higher density and lower water absorption for structural integrity, while the outer layer has lower density and higher water absorption for effective water pickup and release. This local differentiation of material properties enables the roller to perform multiple functions simultaneously with reduced overall thickness.
2Productivity
If squeezing force is increased to remove water from the sponge roller, then water removal efficiency is improved, but resistance to rolling increases and energy is wasted
Solution Approach 1:
The sponge roller is segmented into layers with different water release characteristics. The outer layer releases water more easily through its porous structure and lower density, while the inner layer provides structural support. This segmentation allows water to be released from the outer layer without requiring excessive squeezing force that would create high rolling resistance.
Solution Approach 2:
The sponge roller utilizes porous sponge materials with different pore structures in different layers. The outer layer has a porous structure that facilitates easy water release, allowing water to be expelled with minimal squeezing force, thereby reducing rolling resistance and energy consumption while maintaining effective water removal.

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.
