Flue and vent grilling system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grilling appliances face issues with rapid escape of moisture, heat, and smoke, leading to inefficient cooking, hot spots, dry environments, and increased fuel consumption, as these appliances direct heat and smoke away from food, reducing flavor exposure and cooking performance.
Innovation Solution
A flue and vent grilling system that includes a body with a hood, an outer shell with an exhaust port, a flue with input and output, and a grating, allowing for controlled air intake and smoke management, which enhances moisture retention and smoke flavoring by recirculating heat and smoke within the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If moisture, heat, and smoke are allowed to escape rapidly through the top vent, then the grill structure is simple and easy to manufacture, but cooking performance deteriorates due to hot spots, cold spots, dry cooking environment, and reduced smoke flavoring
Solution Approach 1:
The grill is segmented into distinct functional zones: a cooking chamber for food preparation, a smoke chamber for smoke generation and circulation, and a water pan section for moisture control. This segmentation allows each zone to perform its specific function optimally while maintaining overall system simplicity
Solution Approach 2:
The patent employs a nested structure where the water pan is positioned within the cooking chamber, the smoke chamber is integrated alongside the cooking chamber, and multiple components are housed within a compact outer shell. This nesting approach maintains simplicity while enabling complex smoke and moisture management functions
2Loss of substance
If heat and smoke are directed away from food for rapid venting, then moisture escape is controlled, but smoke flavoring and cooking efficiency deteriorate due to reduced exposure to flavoring smoke
Solution Approach 1:
The flue system creates a continuous circulation path for smoke and heat through the cooking chamber, ensuring that smoke continuously flows over the food surface. This continuous exposure maximizes smoke flavoring and cooking efficiency while the water pan continuously evaporates to maintain moisture levels
Solution Approach 2:
The flue acts as an intermediary structure that guides and directs smoke and heat flow between the combustion chamber and the food surface. It mediates the interaction between heat source, smoke, and food, ensuring optimal exposure while the water pan serves as an intermediary for moisture management
3Reliability
If a flue and vent system is implemented for smoke management, then smoke flavoring and moisture retention improve, but device complexity increases due to additional components
Solution Approach 1:
The flue structure serves multiple functions simultaneously: it acts as a smoke conduit, a heat distribution channel, and a structural support element. The water pan simultaneously provides moisture through evaporation and acts as a heat sink. This multi-functionality reduces the need for separate dedicated components for each function
Solution Approach 2:
The patent merges the smoke circulation function with the heat distribution function into a single flue system. The water pan is combined with the cooking chamber structure rather than being a separate external component. This merging approach maintains improved smoke flavoring and moisture retention while minimizing the increase in device complexity
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 system significantly improves cooking efficiency, retains moisture, and enhances smoke flavoring, reducing fuel consumption and cooking time by managing heat and smoke effectively within the grilling environment.
Implementation Method 1
a flue attached to the outer shell, the flue including a flue output and a flue input... recirculating heat and smoke within the system
Implementation Method 2
The convection gasses and smoke typically rises up through an internal volume of the grill and exit through a top vent
