Angled Melamine Foam Sponge for Cleaning Corners and Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sponge products are ineffective in reaching into corners and along edges for effective scrubbing and cleaning due to their design limitations.
Innovation Solution
A sponge product with a melamine foam body and an abrasive layer, where the melamine foam and abrasive portions are configured in parallel layers with angled surfaces to form a unitary block, allowing the sponge to effectively reach into corners and edges for cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional sponge products are used, then the cleaning function is provided, but the ability to reach into corners and edges is insufficient
Solution Approach 1:
The cleaning product is divided into distinct functional segments: a foraminous melamine resin portion and an abrasive portion, each with different cleaning mechanisms. The product is also segmented into multiple working edges (first, second, third, and fourth working edges) that can be selectively applied to different surface geometries including corners and edges
Solution Approach 2:
The sponge product incorporates asymmetric geometric features including inclined surfaces and working edges at various angles (acute and obtuse angles). This asymmetric design allows the product to conform to and effectively clean non-planar surfaces such as corners, edges, and contoured surfaces that symmetric conventional sponges cannot reach
2Adaptability or versatility
If a unitary cleaning product with both sponge and abrasive portions is used, then cleaning versatility is improved, but the ability to effectively scrub corners and edges remains insufficient
Solution Approach 1:
The invention extends the cleaning capability from two-dimensional surface cleaning to three-dimensional corner and edge cleaning by incorporating working edges that protrude at various angles. The inclined surfaces and angled working edges create a three-dimensional cleaning interface that can access and clean corner regions and edge profiles that planar sponges cannot reach
3Ease of operation
If the sponge product has a low profile design, then maneuverability is improved, but the structural complexity increases to achieve angled working edges
Solution Approach 1:
The foraminous melamine resin portion and the abrasive portion are merged into a single unitary cleaning product through adhesive bonding. This integration allows the product to maintain a compact low-profile structure while incorporating multiple working edges and inclined surfaces, eliminating the need for separate cleaning tools and reducing overall structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The product enables effective cleaning of edges and corners, providing both aggressive scrubbing and gentle cleaning capabilities with its melamine foam and abrasive surfaces, respectively, while maintaining a low profile for easy maneuverability.
Implementation Method 1
An abrasive is layer adjacent only to the upper surface of the melamine foam body layer and attached thereto to form a unitary product

AI summary
A sponge product for cleaning a work surface includes an open-cell melamine foam body layer having a front wall, rear wall, first sidewall or second sidewall that is inclined and at an acute angle relative to the upper surface of the body layer. An abrasive layer is adjacent the upper surface of the melamine foam body layer forming a unitary product. The abrasive layer has at least one of the front wall, rear wall, first sidewall or second sidewall forming an obtuse angle with the lower surface of the abrasive layer, and the abrasive layer upper surface and at least one front wall, rear wall, first sidewall or second sidewall forms a working edge having an acute angle, and the working edge remains flat against the work surface when a force is applied to the sponge product.
