Profiled Baking Sheet With Elevated Domes For Even Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baking trays require frequent food turnover to achieve even browning and ventilation, complicating the cooking process and often necessitating non-stick coatings to prevent adhesion.
Innovation Solution
A baking sheet with a profiled surface, where the height of the profiling is significantly greater than the material thickness, allowing baked goods to rest and ventilate on the underside without the need for turning or additional non-stick coatings, using embossed dome-shaped elevations and depressions that can withstand high temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flat baking sheet surface is used, then the manufacturing process is simple, but the food requires turning during baking to achieve even browning and ventilation
Solution Approach 1:
The invention transitions from a flat two-dimensional surface to a three-dimensional profiled surface with elevations and depressions. This dimensional change allows hot air to circulate underneath the food through the depressions, eliminating the need to turn the food during baking while maintaining even browning and ventilation on all sides.
2Ease of manufacture
If a flat baking sheet surface is used, then the contact area with food is large, but this requires additional non-stick coatings to prevent adhesion
Solution Approach 1:
By creating a profiled surface with elevations and depressions, the actual contact area between the food and the baking sheet is reduced to only the peaks of the elevations. This dimensional change naturally minimizes adhesion points, eliminating the need for additional non-stick coatings while maintaining ease of manufacture.
3Strength
If the material thickness is increased to provide structural integrity, then the strength is improved, but the ventilation capability is reduced
Solution Approach 1:
The invention creates deep depressions that extend through the material thickness, forming ventilation channels. This dimensional change allows effective ventilation even with thin materials (10-100 μm), as the vertical depth of the depressions provides adequate air flow paths without requiring increased material thickness.
4Ease of operation
If a profiled surface with high elevations is created, then the ventilation and non-stick properties are improved, but the manufacturing complexity increases
Solution Approach 1:
The profiled surface is created by segmenting the continuous surface into discrete elevations and depressions at regular intervals. This segmentation simplifies the manufacturing process, as the pattern can be reproduced using standard embossing rollers with corresponding凸起和凹陷 patterns, making the complex-looking surface easy to manufacture.
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
Enables even cooking and ventilation on all sides without turning the food, reducing mechanical stress and eliminating the need for non-stick coatings, while maintaining structural integrity at high temperatures.
Implementation Method 1
the hot air in the baking chamber can reach all surfaces
Implementation Method 2
the material can be embossed or pressed, with embossing being able to take place via heated rollers
Implementation Method 3
embossing being able to take place via heated rollers, which can also introduce the profiling into the baking base in continuous operation

AI summary
The baking support (1) has a sheet or a strip of small or thick heatproof material, where the material has a profiling. The profiling is higher than the thickness of the material. The height of the profiling is thirty times as large is as the thickness of the material. The baking support is used in material such as paper, a plastic, fleece material or a metal foil.
