Scraper Sponge with Rigid Attachment for Hardened Substance Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sponges are too soft and pliable to effectively scrape away unwanted substances like dirt, hardened oils, or grease from surfaces, especially in tight corners and crevices, and existing scraper sponge solutions are often bulky, inconvenient, or economically inefficient.
Innovation Solution
A scraper sponge design featuring a sponge body with a securely attached scraper attachment that provides a rigid edge for scraping, allowing for easy manipulation and use of multiple surfaces, with a scraper cap that can be fixedly secured using adhesive or heat fusion, and made from materials like natural rubber, synthetic rubber, or plastics, enabling effective removal of substances from various surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional sponge is used for cleaning, then it is absorbent and easy to manipulate, but it is too soft to scrape away hardened substances or substances in tight corners and crevices
Solution Approach 1:
The patent combines a conventional sponge with a rigid scraper attachment to create a dual-function tool. The sponge provides absorbency and ease of manipulation, while the rigid scraper attachment provides the necessary rigidity to scrape away hardened substances and reach tight corners. This merging resolves the contradiction by integrating both soft and rigid components into a single operative tool.
Solution Approach 2:
The invention uses composite construction by attaching a rigid material (such as plastic or metal) scraper to a flexible sponge material. This composite structure allows the tool to exhibit both the softness and absorbency of the sponge and the rigidity and scraping capability of the rigid attachment, thereby resolving the contradiction between softness for ease of manipulation and rigidity for effective scraping.
2Strength
If an abrasive layer is added to a sponge to enable scraping, then it can remove some substances, but it still does not provide a rigid enough edge to effectively scrape substances in tight corners and grooves
Solution Approach 1:
The invention segments the cleaning tool into distinct functional components: a sponge body for absorbency and a separate rigid scraper attachment for scraping. The scraper attachment is designed with a thin, rigid edge that can access tight corners and grooves, while the sponge portion provides flexibility and absorbency. This segmentation allows each component to excel at its specific function without compromising the other.
Solution Approach 2:
The rigid scraper attachment is designed with a thin edge that concentrates scraping force at a specific location, enabling effective access to tight corners and grooves. The local quality of the scraper edge provides the necessary rigidity and precision for difficult-to-reach areas, while the overall tool maintains the sponge's flexibility and absorbency properties.
3Strength
If a scraper attachment is securely inserted into the sponge, then it provides effective scraping, but it precludes use of the total sponge surface area
Solution Approach 1:
The scraper attachment is positioned in a specific location on the sponge (typically centered or offset) rather than covering the entire surface. This dimensional placement allows the scraper to provide effective scraping at its location while leaving the majority of the sponge surface area available for cleaning tasks. The tool operates effectively in both scraping and general cleaning modes without requiring full surface coverage by the scraper.

AI summary
A scraper sponge for cleaning and scraping away unwanted substances from an object or surface comprising a sponge body defining a first surface, first layer, second layer, third layer, second surface opposite the first surface, a continuous side surface around the perimeter; and the back of a scraper attachment that is inserted through an aperture in layers two and three then rests firmly against the first layer where it borders the second layer and a smaller cylinder shaped part on the back of the scraper attachment is inserted through a smaller aperture approximately through the middle of the first layer and first surface and held in place by a scraper cap and fixedly secured with adhesive. The entire surface area of the scraper, on its front surface, is covered with pyramid shaped points extending outwardly in the direction of the second surface of the sponge body and is made level with the second surface of the sponge body when forces are applied to the top surface of the scraper cap and subsequent back of scraper attachment to manipulate the rigid scraper on a hard surface. The sponge body has three surfaces available for cleaning and scouring: the first surface, front scraper attachment surface and second surface. The seamless second layer, third layer, and continuous side surface of the second and third layer are made of the same sponge-like cellulose material. As an alternative, the second layer, third layer, second surface, and the continuous side surface of the second and third layer are not made of the same material and the sponge body has at least four surfaces adapted for cleaning and scouring; the first surface, scraper attachment front surface, the continuous side surface of layer two and the second surface.
