Solution Overview

Problem

Commercially available grill cleaning tools often become clogged with debris and struggle to effectively remove charred debris from the rounded surfaces of grill grates, leaving behind residue and affecting food taste and appearance.

Innovation Solution

A barbeque grill scraper with a scraping end made of heat-responsive material, such as wood species, that conforms to the grill surface as it is slid back and forth, forming grooves that match the surface profile to clean the entire cooking surface of char and debris, with optional replaceable ends for different temperatures and seasoning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a hard scraping surface is used to clean the grill grate, then the upper surface can be cleaned effectively, but the rounded surfaces and sides cannot be cleaned well, leaving charred debris behind

Engineering Contradiction:

Improvecleaning effectiveness on upper surfaceVSAvoidconformability to rounded surfaces

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The scraping surface is made from a heat-responsive material that changes its physical properties (softness/flexibility) in response to the heat of the grill grate. When heated, the material becomes soft and conformable to rounded surfaces, and when cooled, it returns to a rigid state for structural support. This parameter change allows the scraper to adapt to different surface geometries while maintaining cleaning effectiveness.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The scraping surface is constructed as a thin, flexible element made of heat-responsive material that can bend and conform to the contours of the grill grate. This flexible structure allows the scraper to wrap around rounded surfaces and maintain contact with the grilling surface, enabling effective cleaning of sides and bottoms that rigid scrapers cannot reach.

Inventive Principle:

Principle #30Flexible shells and thin films

2Strength

If a rigid scraper is used to clean the grill grate, then structural strength is maintained, but the scraper cannot conform to the physical layout and rounded surfaces of the grate

Engineering Contradiction:

Improvestructural strength of scraperVSAvoidconformability to grill surface layout

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The scraper utilizes a heat-responsive material that undergoes a thermal transition: at room temperature, the material maintains structural strength and rigidity for handling and storage; when exposed to the heat of the grill grate during use, the material softens and becomes flexible, allowing it to conform to the grill surface layout and rounded contours.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The scraper transitions from a static, rigid structure to a dynamic, adaptable form through thermal exposure. The material's physical state changes from rigid to flexible in response to environmental conditions (grill heat), enabling the scraper to dynamically adapt its shape to match the grill grate's physical layout during the cleaning process.

Inventive Principle:

Principle #15Dynamics

3Productivity

If a brush is used to clean the grill grate, then initial debris can be removed, but the brush becomes clogged with debris making it ineffective for continued cleaning

Engineering Contradiction:

Improveinitial cleaning capabilityVSAvoidconsistent cleaning performance

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The invention extracts the problematic bristle structure from the cleaning tool and replaces it with a continuous scraping surface made of heat-responsive material. This scraping surface does not have individual bristles that can trap and hold debris,而是 provides a smooth surface that allows debris to be lifted and removed continuously without clogging, maintaining consistent cleaning performance throughout use.

AI summary

A barbeque grill scraper and related methods of use that utilize a scraping end formed of a heat-responsive material to remove char and other debris from the grilling surface. The grill scraper includes a conformable scraping edge formed of the heat-responsive material. As the conformable scraping edge is drawn back and forth along the heated grilling surface, a combination of pressure applied by a user as well as the heat of the grill surface results in the formation of individual grooves along the conformable scraping edge, wherein each groove is formed to match an upper profile of the grilling surface. Over time, the grooves fully conform to the upper profile of the grilling surface such that an entire cooking surface can be scraped clean of char and debris.
