BBQ Grill Scraper with Conformable Edge to Reduce Wire Bristle Hazards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing BBQ grill cleaning tools, particularly wire brushes, pose food safety hazards and are ineffective in removing debris from all surfaces of the grill grate, while metal scrapers can damage certain grates.
Innovation Solution
A BBQ grill scraper with a wearable, conformable scraping edge and a protrusion 'tooth' that fits into grill grate openings, allowing for straight-line movement and conforming to the grate surface over time, combined with an I-shaped cleaning tool for reaching sides and underside debris, and optional features like a non-slip grip and bottle opener.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wire brushes are used to clean grill grates, then debris removal capability is improved, but food safety hazards increase due to loose bristles contaminating food
Solution Approach 1:
The patent removes the harmful wire bristles from the cleaning tool entirely, extracting only the useful debris removal function. The cleaning surface is replaced with a rigid scraper blade that scrapes debris off the grate without the risk of loose particles contaminating food.
Solution Approach 2:
The scraper blade is designed as a replaceable component that can be discarded when worn. This disposable approach eliminates the safety hazard of loose bristles while maintaining effective debris removal, as the rigid blade can be replaced rather than repaired.
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 scraper blade is designed with different properties at different locations - the leading edge is rigid for effective scraping, while the body material is selected to be less abrasive than metal. This local differentiation allows effective debris removal while minimizing damage to the grill grate surface.
Solution Approach 2:
The scraper blade uses composite or composite-like materials that combine rigidity for scraping effectiveness with reduced abrasiveness to protect the grill grate. The material selection balances these two competing requirements.
3Ease of operation
If scrapers with ridged surfaces are used to clean grill grates, then top surface cleaning is improved, but cleaning completeness worsens as debris remains on sides and bottoms
Solution Approach 1:
The cleaning tool is segmented into multiple functional components: a main scraper blade for the top surface, and additional protrusions or extensions that reach into the gaps between grates to clean sides and bottoms. This segmentation allows comprehensive cleaning of all grate surfaces.
Solution Approach 2:
The scraper design extends cleaning into the third dimension by adding vertical protrusions that reach between grates, rather than only horizontal scraping of the top surface. This multi-dimensional approach ensures complete debris removal from all grate surfaces.
4Strength
If the scraping edge is made rigid for durability, then tool strength is improved, but adaptability to different grate surfaces worsens
Solution Approach 1:
The scraper blade is designed with controlled flexibility that allows it to dynamically adapt to the grate surface profile while maintaining overall structural strength. The blade can flex slightly to conform to irregular surfaces but remains rigid enough for effective scraping.
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
Effectively removes char and debris from all grill surfaces without safety hazards, conforms to the grate for improved cleaning, and includes features for enhanced usability and safety.
Implementation Method 1
The scraping end is made of a material that can wear or conform to the grill grate over time and use
Implementation Method 2
The scraping edge is drawn back and forth across a hot grill grate surface to remove char and other debris
Implementation Method 3
The scraping end includes a protrusion or 'tooth' that fits into the adjoining openings in the grill grate, thus allowing the scraping edge to easily travel in a straight path across the grates
Implementation Method 4
The scraping edge is drawn back and forth across a hot grill grate surface to remove char and other debris
Implementation Method 5
The scraping edge is drawn back and forth across a hot grill grate surface to remove char and other debris

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 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.
