Griddle Assembly Heat Shield for Uniform Temperature Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooktop appliances with single or multiple burners struggle to evenly heat griddle cooking surfaces, leading to thermal gradients and hot or cold spots.
Innovation Solution
A griddle assembly with a heat shield positioned between the griddle and the gas burner, which alters the heat transfer path to achieve more uniform heating across the griddle surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single elongated burner is used for the griddle, then the device complexity is reduced, but the temperature uniformity across the griddle cooking surface deteriorates
Solution Approach 1:
A heat shield is introduced as an intermediary component between the gas burner and the griddle cooking surface. The heat shield intercepts and redistributes thermal energy, converting the direct localized heating from the burner into a more uniform heat distribution across the griddle surface, thereby resolving the temperature uniformity issue without increasing burner complexity
2Temperature
If multiple burners are used for the griddle, then the temperature uniformity is improved, but the device complexity increases
Solution Approach 1:
The heat shield serves as a mediating structure that enables uniform temperature distribution using a single burner. By positioning the heat shield between the burner and griddle surface, it redistributes thermal energy to eliminate hot and cold spots, achieving the temperature uniformity benefit of multiple burners while maintaining the simplicity of a single-burner configuration
3Use of energy by moving object
If direct heating from the burner to the griddle is used, then the heating efficiency is maximized, but thermal gradients across the cooking surface increase
Solution Approach 1:
The heat shield acts as a thermal intermediary that captures concentrated heat from the burner and redistributes it across the griddle surface. This maintains high heating efficiency by preserving the thermal energy from the burner while eliminating thermal gradients through the redistributing effect of the heat shield
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 heat shield enhances even temperature distribution and reduces thermal gradients, maintaining consistent cooking performance without compromising maximum heating capacity.
Implementation Method 1
a heat shield positioned adjacent to a bottom surface of the griddle. The heat shield is positioned over the gas burner and along a vertical direction between the bottom surface of the griddle and the gas burner
