Alcohol Cooking Tank Geometry for Homogeneous Flame Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking appliances that use alcohol for food heating struggle with achieving homogeneous cooking due to inefficient flame distribution, leading to inconsistent cooking results.
Innovation Solution
A cooking appliance design featuring a tank with an inwardly inclined sidewall and a conically inclined base, which directs the combustion flame towards a container, ensuring consistent and reproducible cooking. The tank's shape, including a smaller top diameter and an inverted truncated cone opening, enhances flame confinement and directionality for improved cooking quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple tank design is used for alcohol combustion, then the device complexity is reduced, but the cooking homogeneity deteriorates
Solution Approach 1:
The tank is designed with a conical base and inwardly inclined sidewalls, creating a curved geometric configuration that directs flames uniformly toward the container. This curvature transforms the flame distribution pattern to achieve homogeneous cooking without requiring complex mechanical control systems.
Solution Approach 2:
The tank geometry parameters are specifically optimized: the sidewalls are inclined at a specific angle inwardly, and the base has a defined conical shape. These parameter changes create a confinement volume that naturally directs and distributes flames evenly, achieving homogeneous cooking through geometric optimization rather than complex active control.
2Ease of operation
If the tank has a larger opening for easy pouring, then the ease of operation is improved, but the flame confinement deteriorates
Solution Approach 1:
The tank opening is segmented into two functional zones: an upper inverted truncated cone section that facilitates easy pouring with a larger effective opening, and a lower conical base section that provides flame confinement. This segmentation allows each zone to optimize its specific function without compromising the other.
Solution Approach 2:
The tank design utilizes vertical dimensionality with the inverted truncated cone opening positioned above the conical base. This vertical arrangement separates the pouring function (at the top opening) from the combustion function (at the lower confined base), allowing both large opening and good confinement to coexist in different spatial dimensions.
