Baking Pan Insert Geometry for Crisp Edges and Even Baking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baking pans fail to produce baked goods with a consistent crisp edge and chewy center, as edges adjacent to the pan sides often turn out firmer than the center, and existing solutions like crested pans or spring form pans do not adequately address this issue by providing additional cooking surfaces or airflow.
Innovation Solution
A baking pan system with a base pan and an insert member, where the insert rim extends at a 90-degree angle, creating a critical ratio between the inner and outer sides to achieve crisp edges and chewy centers, along with removable dividers and a serving system for easy handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional baking pans are used, then the structure is simple and easy to manufacture, but the edges of baked goods have uneven texture (chewy rather than crisp) and cooking time is longer
Solution Approach 1:
The baking pan is segmented into a base pan and a separate insert member with raised rims. This segmentation allows the insert to create additional cooking surfaces and airflow channels, producing crisp edges through enhanced heat circulation while keeping the base pan simple for manufacturing.
Solution Approach 2:
The insert member is nested within the base pan, with the insert's outer periphery fitting inside the base pan's interior periphery. This nesting arrangement allows the complex insert structure to be stored compactly within the simpler base pan when not in use, and enables the insert to modify heat distribution without requiring a completely new pan design.
2Area of stationary object
If crests are added to increase baking surface contact, then surface contact is increased, but additional airflow is not provided and sharp evenly firm edges are not achieved
Solution Approach 1:
Instead of adding crests that only increase surface contact area in two dimensions, the insert member introduces a vertical dimension with raised rims that create three-dimensional airflow channels. This allows hot air to circulate above and around the batter, providing both increased effective cooking surface and enhanced convective heat transfer for faster, more uniform cooking.
3Productivity
If bundt pan inserts are used, then additional airflow is provided, but firm edges are not achieved due to smooth corners and bund scallops
Solution Approach 1:
The insert member features raised rims with specific geometric characteristics (non-scalloped edges and controlled corner radii) that differ from the overall pan shape. This local quality modification at the edges creates focused airflow patterns and heat distribution that produce firm, crisp edges, while the rest of the pan maintains geometry suitable for the desired baked good shape.
4Productivity
If the ratio between inner rim and outer sides is not optimized, then manufacturing is easier, but firm edges and reduced cooking time are not achieved
Solution Approach 1:
The insert member's dimensions are specifically designed with a predetermined ratio between the inner rim diameter and outer side dimensions. This parameter optimization creates optimal airflow velocity and heat distribution patterns that reduce cooking time and produce firm edges, while the ratio-based design simplifies manufacturing by providing clear dimensional relationships between features.
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 pan system effectively produces baked goods with crisp edges and chewy centers by optimizing heat circulation and cooking time, while maintaining structural integrity and ease of use through its design and materials.
Implementation Method 1
The pan has three cooking surfaces that produce a crisp edge and reduce cooking time through the creation of additional airflow
Implementation Method 2
A baking pan system with a base pan and insert member, where the insert rim extends at a 90-degree angle, creating a critical ratio between the inner and outer sides to enhance airflow and heat circulation

AI summary
The baking pan disclosed herein creates a single, or double, bite sized baked product that has a crispy outer edge and a chewy interior. The ratio between the side of the interior insert of the pan and the exterior side of the pan is critical to form the desired product. The pan can range in size from about a 5 inch exterior diameter to a 16 inch exterior diameter with the interior insert increasing accordingly.
