Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional twisted wire brushes for cleaning grills are prone to wear, breakage, and pose health hazards due to detached bristles, and have limited surface area for cleaning, requiring excessive force and posing safety risks when cleaning hot surfaces.
Innovation Solution
A multi-handled twisted wire grill brush design with three brushes, each with a twisted core wire and spring coils arranged at specific angles and diameters, providing increased surface area and improved ergonomics to reduce the risk of injury during cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional wire brushes use thick, rigid metal bristles to achieve strong cleaning force, then cleaning effectiveness is improved, but bristle durability deteriorates due to wear, bending, and breakage
Solution Approach 1:
The patent changes the material parameter of bristles from rigid metal to flexible wire, and adjusts the structural parameter by arranging bristles at multiple angles (0°, 45°, 90°) relative to the core axis. This allows the brush to maintain cleaning effectiveness through geometric arrangement while improving durability through material flexibility and stress distribution.
Solution Approach 2:
The patent uses composite construction by combining multiple wire materials with different properties (stainless steel, aluminum, copper) in the same brush assembly. Each material contributes different characteristics: stainless steel for strength, aluminum for flexibility, and copper for corrosion resistance, creating a composite brush that balances cleaning force and durability.
2Force
If conventional wire brushes use thick, rigid metal bristles to achieve strong cleaning force, then cleaning effectiveness is improved, but health safety deteriorates due to detached bristles contaminating food
Solution Approach 1:
The patent changes the material parameter from rigid metal to flexible wire and adjusts the structural parameter by arranging bristles at multiple angles. This creates a brush that maintains cleaning force through geometric arrangement while reducing the tendency of bristles to detach and contaminate food.
Solution Approach 2:
Instead of making bristles rigid to prevent detachment, the patent inverts the approach by making them flexible and arranging them at multiple angles, which naturally secures them through geometric interlocking while maintaining cleaning effectiveness.
3Productivity
If a single brush design is used to clean hot grill surfaces requiring two hands for leverage, then cleaning capability is maintained, but operator safety deteriorates due to risk of hand injury from hot surfaces
Solution Approach 1:
The patent divides the single brush into three separate brush assemblies arranged at different angles (0°, 45°, 90°) relative to the handle. This segmentation allows the operator to effectively use one hand on the handle while the distributed brush surfaces provide adequate cleaning capability, reducing the need for a second hand near the hot grill surface.
Solution Approach 2:
The patent adds angular dimensionality by arranging brush surfaces at multiple angles (0°, 45°, 90°) rather than in a single plane. This three-dimensional arrangement increases the effective cleaning surface area and distributes cleaning force across different orientations, enabling effective one-handed operation.
4Device complexity
If a single brush with limited surface area is used for cleaning, then device simplicity is maintained, but cleaning efficiency deteriorates due to insufficient brush surface area
Solution Approach 1:
The patent divides the cleaning function into three separate brush assemblies, each with its own twisted wire core and bristle arrangement. This segmentation increases the total brush surface area available for cleaning while maintaining relatively simple individual brush structures that are easy to manufacture.
Solution Approach 2:
The patent utilizes angular dimensionality by arranging the three brush surfaces at different angles (0°, 45°, 90°) relative to the handle axis. This three-dimensional configuration maximizes the effective cleaning surface area in multiple directions without significantly increasing the overall device footprint or complexity.
