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 surfaces, and difficulty in removing food particles and bacteria, which can lead to contamination and surface damage.
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 improved abrasive capabilities and resilience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional wire or plastic bristle brushes are used to clean grate cooking surfaces, then the brushing action can reach crevices and bristle tips contact the surface, but the brushes lack durability, have few abrasive surfaces, and quickly become permanently deformed
Solution Approach 1:
The patent changes the physical state and mechanical properties of the cleaning element by replacing rigid bristles with spring-loaded abrasive pads. This parameter change enables the cleaner to maintain resilience while providing durable abrasive surfaces that resist permanent deformation during repeated use on cooking surfaces.
Solution Approach 2:
The invention combines multiple materials and mechanisms into a composite cleaning device: springs provide elastic resilience, abrasive pads provide cleaning surfaces, and the combination creates a system that achieves both durability and reliability by allowing the abrasive elements to be replaced while the spring mechanism remains reusable.
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 and between bristles making them difficult to clean
Solution Approach 1:
The cleaning device is segmented into multiple independent abrasive pads arranged in a grid pattern, each pad being separately accessible. This segmentation allows food particles to be easily removed from between individual pads without requiring deep cleaning of tight crevices, while still providing broad surface coverage through the array of pads.
Solution Approach 2:
The use of flexible abrasive pads instead of rigid bristles creates larger gaps between cleaning elements. These flexible pads can conform to surface contours while maintaining open spaces that prevent food particle accumulation, making the device easy to clean and maintain.
3Productivity
If conventional bristle brushes are used to clean grate cooking surfaces, then some cleaning action is provided, but they are ineffective in removing substances and tend to scratch delicate surfaces
Solution Approach 1:
The abrasive pads are designed with controlled abrasive properties that provide effective cleaning power where needed while maintaining a surface structure that prevents excessive scratching. The local quality of the abrasive surface is optimized to remove food substances effectively without damaging the underlying cooking surface.
Solution Approach 2:
The spring-loaded mechanism provides dynamic pressure control, allowing the abrasive pads to apply sufficient force for effective cleaning while automatically adjusting to surface contours. This dynamic action prevents rigid scratching that occurs with conventional brushes while maintaining high cleaning productivity.
