Scraper Sponge with Integrated Rigid Scraper for Tight-Space Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sponges are too soft and pliable to effectively scrape away substances like dirt, hardened oils, or grease from tight corners, grooves, and crevices, and existing scraper sponge solutions are often bulky, inconvenient, or unsafe, lacking a flexible and ergonomic design that allows full use of the sponge surface area.
Innovation Solution
A scraper sponge with a securely attached, semi-rigid scraper integrated into a sponge body, featuring pyramid-shaped edges and a contoured O-shaped ring for easy manipulation, allowing for effective scraping in tight spaces and comfortable handling, while maintaining the sponge's absorbent properties.
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 and pliable to effectively scrape away unwanted substances from tight corners, grooves, and crevices
Solution Approach 1:
The patent combines a conventional sponge with a rigid scraper component into a single integrated cleaning device. The scraper is securely attached to the sponge body, allowing the user to leverage both the sponge's absorbency and maneuverability and the scraper's rigidity for effective scraping of stubborn substances from difficult-to-reach areas.
Solution Approach 2:
The cleaning device uses composite construction by attaching a rigid scraper material (such as plastic or metal) to a flexible sponge material. This composite structure enables the device to perform both soft cleaning and hard scraping functions, resolving the contradiction between softness for manipulation and rigidity for scraping power.
2Strength
If an abrasive layer is added to a sponge to enable scraping, then scraping capability is improved, but the device still cannot effectively remove substances from tight corners and grooves due to lack of rigid edge
Solution Approach 1:
The scraper component is designed with specific local characteristics including a rigid structure for scraping power, a tapered or angled edge for accessing tight corners and grooves, and a secure attachment mechanism to the sponge. This localized optimization of structure and geometry enables effective scraping in difficult-to-reach areas while maintaining overall device functionality.
3Strength
If existing scraper sponge solutions are designed with integrated scrapers, then scraping function is added, but the design becomes bulky and precludes use of total sponge surface area
Solution Approach 1:
The scraper is attached to a specific portion of the sponge rather than covering the entire surface, allowing different regions of the sponge to serve different functions. This segmented approach maintains access to various surfaces of the sponge for cleaning while the scraper handles scraping tasks, avoiding bulkiness and maximizing usable surface area.
Solution Approach 2:
The scraper is positioned to extend from one surface of the sponge, utilizing the third dimension (depth/thickness) rather than occupying horizontal space. This dimensional arrangement allows the scraper to be integrated without significantly increasing the overall footprint or blocking access to other sponge surfaces, reducing bulkiness while maintaining functionality.

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 secured to the first layer opposite the first surface and the scraper defined by the first layer and an aperture through and approximately in the middle of the second layer, third layer and second surface of the sponge body. The entire surface area of the scraper, on it's 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 first surface and subsequent back of scraper 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 surface and second surface. The seamless second layer, third layer, third surface, 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 front surface, the continuous side surface of layer two and the second surface. As a second alternative, the scraper and aperture are placed on the width side of the scraper sponge.
