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

VSEngineering 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

Engineering Contradiction:
Improvebrush durabilityVSAvoidsurface scratching
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

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

Inventive Principle:
Principle #35Parameter changes

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

Inventive Principle:
Principle #40Composite materials

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

Engineering Contradiction:
Improvecleaning coverage areaVSAvoidbrush cleaning maintenance
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

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

Inventive Principle:
Principle #30Flexible shells and thin films

3Productivity

If rigid scrapers are used to remove debris from cooking surfaces, then cleaning efficiency is improved, but the surfaces are scratched and damaged

Engineering Contradiction:
Improvedebris removal efficiencyVSAvoidsurface damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

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

Inventive Principle:
Principle #35Parameter changes

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

Engineering Contradiction:
Improvebristle strengthVSAvoidsurface contour conformance
Core Design Contradiction:
StrengthVSAdaptability or versatility

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

Inventive Principle:
Principle #40Composite materials

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

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
