Grill grate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Open grill grates allow drippings to burn and create messes, leading to flare-ups, mold, bacteria growth, and rust, while trays disrupt smoke flow and flavor.
Innovation Solution
A grill grate with a continuous bottom and dormers that directs drippings into grease channels, allowing smoke to pass through while containing drippings, enabling easy cleaning and preventing flare-ups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If open grill grates are used, then smoke flow and grilling flavor are maintained, but drippings burn and cause flare-ups creating mess and safety hazards
Solution Approach 1:
The grill grate is segmented into flavor bars with integrated grease channels between them, separating the functions of smoke generation and drip containment. This segmentation allows the grate to maintain open structure for flavor while directing drippings into channels that prevent flare-ups.
Solution Approach 2:
The grease channels act as intermediary structures between the flavor bars, capturing drippings before they can cause harmful flare-ups. These channels serve as a mediating element that preserves the benefits of open grating while eliminating the harmful effects of burning drippings.
2Object-affected harmful factors
If trays or pans are used to catch drippings, then flare-ups and mess are prevented, but smoke flow to grilled food is disrupted lessening distinctive character
Solution Approach 1:
The grease channels are merged directly into the grill grate structure itself, combining the functions of grilling and drip containment in a single integrated component. This eliminates the need for separate trays or pans that would block smoke flow, while still providing effective drip management.
Solution Approach 2:
The grill grate is designed with multi-functionality, serving both as the cooking surface and as the drip containment system. The flavor bars and grease channels work together to simultaneously enable smoke generation and prevent flare-ups, eliminating the trade-off between these functions.
3Ease of operation
If continuous bottom is used to contain drippings, then cleaning is facilitated and flare-ups prevented, but smoke penetration to food is reduced
Solution Approach 1:
The continuous bottom is segmented into discrete grease channels positioned between flavor bars, creating defined pathways for drippings. This segmentation allows smoke to penetrate through the spaces between channels while still providing effective drip containment and easy cleaning of the channel structures.
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 effectively contains drippings, prevents flare-ups, and maintains the flavor and smoke flow of open-grate grilling without the mess, ensuring cleaner and safer grilling.
Implementation Method 1
The dormer is configured to direct drippings around the opening towards the grease channels
Implementation Method 2
The openings allow smoke to reach the meats

AI summary
Grill grates include side walls defining the perimeter of the grill grate and flavor bars, with grease channels between them. The grease channels have continuous, closed bottoms. The flavor bars include dormers. The dormers are configured to direct drippings around the openings, to the grease channels. The dormers can have openings facing substantially towards the grease channels. The grill grates can be formed by methods such as stamping or casting. Stamping the grill grates can include providing metal with flanges and tabs to ensure sufficient material to allow the flavor bars and dormers to be formed, and the grease channels and side walls then sealed through welding. The grill grate can trap drippings in the grease channels while allowing smoke and heat to reach cooked items through the dormers in addition to heat transfer through the material of the flavor bars.
