Folding Barbecue Grill Brush Handle Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional barbecue grill brushes lack leverage and safety features, often requiring users to expose their hands to heat and do not efficiently clean curved or cylindrical grating surfaces, and they do not offer convenient storage options.
Innovation Solution
A foldable and extendable barbecue grill brush with a contoured bristle design and removable cleaning head, featuring a hinge mechanism for adjustable leverage, a forearm wrap-around band for single-handed operation, and a design that allows for hands-free cleaning to prevent burns, along with easy storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional straight fixed length handle is used, then the structure is simple, but the user lacks leverage and must expose hands to heat
Solution Approach 1:
The handle is designed with a folding mechanism that allows it to change configuration between extended and folded states. This dynamic structure provides extended leverage when needed during cleaning operations while allowing compact storage when not in use, resolving the contradiction between operational leverage and structural simplicity.
2Object-affected harmful factors
If a longer handle is used to prevent burns, then hand safety improves, but the brush becomes harder to store
Solution Approach 1:
The folding handle mechanism allows the brush to transition between a long extended configuration during use (keeping hands away from heat) and a compact folded configuration for storage (minimizing space occupation), thereby resolving the contradiction between safety and storage convenience.
Solution Approach 2:
The handle segments are designed to nest within each other when folded, with inner segments storing within outer segments, creating a compact storage profile while maintaining full extension capability during operation for burn prevention.
3Productivity
If traditional straight bristles are used, then manufacturing is simple, but cleaning efficiency on curved surfaces is poor
Solution Approach 1:
The bristle assembly features varying bristle lengths and angles at different positions along the brush head, with longer bristles at the center and shorter bristles at the edges. This local variation optimizes cleaning effectiveness on curved grill surfaces while maintaining manufacturability through systematic fabrication patterns.
Solution Approach 2:
The brush head is designed with curved bristle arrangements that match the curvature of typical grill surfaces. The bristles are angled and varied in length to conform to spherical or cylindrical surface geometries, enhancing contact and cleaning efficiency on curved surfaces while remaining manufacturable through standardized bending processes.
4Volume of moving object
If a fixed cleaning head is used, then the structure is simple, but the brush cannot be stored compactly
Solution Approach 1:
The handle incorporates a folding mechanism with hinge joints and locking features that enable the handle to transition between extended and folded states. This dynamic design allows compact storage while maintaining structural integrity and ease of operation during use, balancing storage convenience with operational simplicity.
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 solution provides superior cleaning efficiency on various grating surfaces, prevents hand burns by maintaining distance from heat, and offers compact storage, enhancing user safety and convenience.
Implementation Method 1
a hinge mechanism for adjustable leverage
Implementation Method 2
The food particles or debris generally falls below the cooking surface, thus leaving a relatively clean cooking surface for future food preparation

AI summary
Provided is a barbecue grill brush including a cleaning head. The barbecue grill brush includes a straight handle. A first end of the straight handle is coupled to the cleaning head and a second end of the straight handle is coupled to a hinge. The barbecue grill brush includes a curved handle. A first end of the curved handle is coupled to an opposite side of the hinge from the straight handle, and the hinge is configured to rotate the curved handle with respect to the straight handle. A first handle grip disposed adjacent to the first end of the curved handle, and a second handle grip disposed at a second end of the curved handle. The second end of the curved handle is opposite to the first end of the curved handle.
