Wearable Grill Scraper Edge for Safe Grate Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing BBQ grill cleaning tools, particularly wire brushes, pose food safety hazards and are inefficient in removing debris from all surfaces of the grill grate, while metal scrapers can damage certain grates and leave residue.
Innovation Solution
A BBQ grill scraper with a wearable scraping edge and protrusion (tooth) made of non-toxic materials like wood, which conforms to the grill grate over time, allowing for effective debris removal from all surfaces without damaging the grate, and an optional L-shaped cleaning tool for reaching sides and underside.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wire brushes are used to clean grill grates, then debris removal efficiency is improved, but food safety hazards increase due to wire bristle ingestion risk
Solution Approach 1:
The patent extracts the harmful wire bristles from the cleaning tool and replaces them with a wooden scraping surface. The cleaning function is maintained through the scraping action of the wood block, while the ingestion hazard is eliminated by removing the wire bristle component entirely.
Solution Approach 2:
The patent employs a wooden block that can be easily replaced. The wooden scraping surface is consumable and can be discarded when worn, providing a safe alternative to durable wire brushes that pose ongoing ingestion risks.
2Productivity
If metal scrapers are used to remove debris from grill grates, then debris removal effectiveness is improved, but grill grate damage increases
Solution Approach 1:
The patent changes the material parameter of the scraping tool from metal to wood. This material substitution maintains the scraping functionality while eliminating the damaging effects associated with metal-on-metal contact, thus protecting the grill grate surface.
3Ease of operation
If ridged scrapers are used to clean grill grates, then top surface cleaning is improved, but side and bottom cleaning effectiveness deteriorates
Solution Approach 1:
The patent adds a protrusion element that extends between the grill grate bars, creating a three-dimensional cleaning capability. This allows the wooden block to access and clean the sides and bottoms of the grate bars, not just the top surface, thereby addressing the dimensional limitation of traditional scrapers.
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 scraper ensures safe and thorough cleaning of BBQ grill grates by preventing wire bristle ingestion and damaging the grill, while the conformable edge and tooth design allow for efficient debris removal from all surfaces, reducing fire hazards and maintaining grill appearance.
Implementation Method 1
The scraping edge is drawn back and forth across a hot grill grate surface to remove char and other debris
Implementation Method 2
the scraping edge will wear or conform to the grate surface to allow for better cleaning
Implementation Method 3
Over time, the scraping edge will wear or conform to the grate surface to allow for better cleaning

AI summary
A barbeque grill scraper that uses a scraping edge with a tooth formed of a wearable material to remove char and debris from the grill grates. The tooth fits between adjoining grill grates to guide the scraping edge and create a plurality of indents in the scraping edge that match the top profile of the grill grates. The grill grates are thus thoroughly cleaned without the health risks associated with wire brush cleaners. Another embodiment further utilizes a protruding cleaning tool to access and clean the lower sides and bottom of the grill grates.
