Chainmail Abrader Scraper Assembly for Non-Scratch Grill Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scrapers with wire or plastic bristles are ineffective in cleaning grate cooking surfaces due to their lack of durability, abrasive limitations, and difficulty in removing substances without scratching the surfaces, as well as accumulation of food particles and bacteria in crevices.
Innovation Solution
A scraper with a chainmail or wire cloth abrader mounted to a frame, featuring a back pressure mechanism that allows the abrader to conform to surfaces, providing enhanced abrasiveness and cleaning efficiency while minimizing surface damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wire or plastic bristle brushes are used to clean grate cooking surfaces, then the brushing action can reach crevices, but the brushes lack durability and effectiveness in removing substances without scratching surfaces
Solution Approach 1:
The patent changes the physical state and properties of the cleaning element by using wire rope with specific diameter ranges (0.03-0.16 inches) and construction (strands twisted together), transforming it from a rigid bristle to a flexible, resilient wire rope bristle that can adapt to surface contours while maintaining durability and preventing scratches
Solution Approach 2:
The wire rope bristle is constructed as a composite structure with multiple strands twisted together, combining flexibility and resilience properties that neither single-material bristles nor rigid scrapers possess, enabling effective cleaning without surface damage
2Area of stationary object
If conventional brushes with tightly packed bristles are used, then coverage area is increased, but food particles and bacteria accumulate in crevices between bristles making them difficult to clean
Solution Approach 1:
The wire rope bristles function as flexible cleaning elements that can be spaced apart while maintaining structural integrity, allowing the cleaning surface to be washed thoroughly without food particle accumulation in tight crevices, unlike rigid tightly-packed bristle brushes
3Productivity
If rigid scrapers are used to remove debris from cooking surfaces, then cleaning efficiency is improved, but the surfaces are scratched and damaged
Solution Approach 1:
The patent transforms the cleaning mechanism from rigid scraping to flexible wire rope bristle action, where the wire rope's flexibility and resilience allow it to remove debris effectively through a combining scraping and brushing action without the surface-damaging effects of rigid scrapers
4Strength
If wire rope bristles are made with larger diameter for durability, then strength is improved, but flexibility and ability to conform to surface contours decreases
Solution Approach 1:
The wire rope bristle uses a composite construction of multiple strands twisted together, where the strand configuration (number of strands, wires per strand) can be adjusted to achieve the optimal balance between strength and flexibility for different cleaning applications
Solution Approach 2:
The wire rope bristle is designed to be resilient and flexible, allowing it to dynamically adapt to surface contours during cleaning motion, unlike rigid fixed-length bristles that cannot conform to irregular surfaces
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 effectively removes debris from grate cooking surfaces without scratching, maintains hygiene by preventing bacterial accumulation, and extends the lifespan of cooking surfaces through improved durability and cleaning efficiency.
Implementation Method 1
an elastic member positioned adjacent to the chainmail body such that the elastic member is capable of applying pressure against the chainmail body enabling the chainmail body to resiliently conform to the contours of the surface
Implementation Method 2
a scraper for use in abrading a surface including a handle attached to a scraper head. The scraper head has chainmail abrader mounted to a frame
