Magnetic Knife Scraper for Stable Blade Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing knife cleaning methods, such as using divots or knife gliders, fail to effectively remove food buildup during cutting, posing safety risks and inefficiencies due to food accumulation and device instability.
Innovation Solution
A magnetically secured knife cleaning device that rests on the spine and sides of the knife, using a magnet to adhere to the blade and move along its length, featuring scrapers to remove food buildup without falling off, ensuring safety and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a knife glider device is used to slide along the blade, then the device can remove food buildup, but the device may improperly move or fall off the knife leading to safety risks
Solution Approach 1:
The patent replaces the mechanical friction-based attachment (knife glider resting on blade) with a magnetic attachment system. The magnet embedded in the cleaning device creates magnetic attraction to the metallic knife blade, securing the device in place while allowing it to slide for food removal, thus eliminating the instability and safety risks of manual handling.
Solution Approach 2:
The magnet acts as an intermediary between the cleaning device and the knife blade. It provides a non-contact attachment mechanism that holds the device securely to the metallic blade during operation, enabling reliable food removal without direct manual contact or risk of detachment.
2Ease of operation
If divots are built into the blade to disrupt surface tension, then food should be knocked off the blade, but the divots do not work and food still stays on the knife
Solution Approach 1:
The cleaning device performs the food removal function autonomously by sliding along the blade and mechanically scraping food residue. This self-service mechanism eliminates the need for manual finger wiping and provides reliable food removal without relying on ineffective blade modifications like divots.
3Ease of operation
If the user uses fingers to wipe away food accumulated on the blade, then food can be removed, but it creates safety issues due to inadvertent cutting of the user's fingers
Solution Approach 1:
The magnetic cleaning device serves as an intermediary tool between the user and the knife blade. It allows food removal without direct finger contact by sliding along the blade and scraping residue, thus eliminating the safety hazard of inadvertent finger cutting while maintaining effective food removal capability.
Solution Approach 2:
The patent substitutes manual finger wiping with a mechanical scraping action performed by the cleaning device. The device's scraper mechanism removes food residue through controlled mechanical motion along the blade, replacing the dangerous manual action with a safe automated process.
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 device provides a safer and cleaner cutting experience by eliminating the need for manual cleaning and preventing device detachment, effectively removing food residue along the blade.
Implementation Method 1
The device includes a magnet that applies a magnetic force to a metallic knife blade and ensures the device stays on the knife
Implementation Method 2
the first scraper and the second scraper are configured to remove matter on a blade of the knife as the device moves on the spine of the knife

AI summary
A knife cleaning accessory device may include a first scraper and a second scraper connected at a connection section such that the first and second scrapers are facing each other. A magnet may be placed in one of the first or second scrapers and the magnet configured to secure the device to the knife. A slot may be positioned between the first and second scrapers. The slot may include an open end wherein the device may be placed on the blade of knife such that it rests on the spine of the knife. The device is moveable on the spine of the knife from a first position to a second position, and the first scraper and the second scraper are configured to remove matter on a blade of the knife as the device moves on the spine of the knife.
