Beveled Scraper Litter Scoop for Hygienic Waste Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for removing cat waste from litter boxes are unpleasant, inefficient, and often require direct hand contact with the waste, leading to health and hygiene concerns.
Innovation Solution
A scoop device with a stainless steel construction, non-stick coating, and a beveled scraper, designed to segregate and remove urine clumps and feces from the litter box without releasing ammonia odors, and featuring a handle for easy handling and hanging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a thin plastic bag is used to manually pick up cat waste, then direct hand contact with waste is achieved, but hygiene and health concerns worsen
Solution Approach 1:
The scoop device serves as an intermediary tool between the user's hand and the cat waste. It features a basket that collects waste and a scraper that removes adhered material, allowing users to handle waste without direct hand contact. The waste is transferred to a separate container or bag through the scoop, eliminating the need to touch waste with bare hands while maintaining operational simplicity.
2Reliability
If clay litter is used to absorb urine and form clumps, then urine isolation is improved, but ammonia odor release worsens when clumps break apart
Solution Approach 1:
The scraper component converts the harmful effect of adhered waste that would otherwise break and release ammonia into a benefit. By effectively removing waste that sticks to the litter box walls and edges, the scraper prevents subsequent breaking and ammonia release. The beveled edge design enhances this by cleanly scraping away adhered material before it can break apart during normal scooping operations.
3Productivity
If a traditional scoop is used to remove waste, then waste removal is achieved, but direct hand contact and unpleasant experiences worsen
Solution Approach 1:
The scoop device is segmented into distinct functional components: a basket for collecting loose waste, a scraper for removing adhered waste, and a handle for user operation. This segmentation allows each component to perform its specific function efficiently while keeping the user's hand separated from the waste throughout the entire process. The waste is contained within the basket and removed via the scraper, never requiring hand contact.
4Ease of operation
If the scoop device has openings to allow litter to fall through, then waste segregation is improved, but structural complexity worsens
Solution Approach 1:
The scoop basket utilizes a porous or perforated structure with openings that allow loose litter to pass through while retaining larger waste clumps. This porous design achieves effective waste separation without requiring complex mechanisms. The simple pattern of holes or slots in the basket provides the necessary filtration function while maintaining structural simplicity and ease of manufacturing.
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 scoop device effectively separates and removes cat waste from litter boxes, reducing direct contact with waste, minimizing odor release, and enhancing hygiene and user comfort.
Implementation Method 1
the device could be coated by a non-stick material such as Teflon®
Implementation Method 2
a beveled scraper... leading edge, or end of the scraper of the scoop device is beveled and sharpened to allow loosening of the material such as urine clump or feces
Implementation Method 3
a stainless steel scoop provided with one or more openings to allow the loose litter material to fall through back into the litter box
Implementation Method 4
handle, which is formed using dense foam material that is uncompressible, and non-slip outer surface providing optimum level of grip

AI summary
A scoop device designed to allow the user to easily segregate urine clump or balls and feces, lift, discard, and wash the device for further use, is disclosed. The scoop device comprises a filter basket, a narrowed wall which includes raised ribs, a beveled scraper, and a handle. The filter basket and beveled scraper, are coated by a non-stick material. The filter basket is a spatula shaped end, positioned between the handle and the beveled scraper end in the scoop device. The filter basket is further extended towards to form the flat beveled scraper configuration in the scoop device. The filter basket and the beveled scraper comprises one or more openings that prevent the scoop device from capturing loose litter material. Further, the scraper of the scoop device is beveled and sharpened to allow loosening of the material such as urine clump or feces, inadvertently adhering to the sides of the litter box.
