Popcorn Popper Cooking Surface With Elevated Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing popcorn poppers often result in burnt or overcooked popcorn due to prolonged contact with the heated cooking surface or oil, requiring active user intervention to prevent burning.
Innovation Solution
A popcorn popper design featuring a cooking surface with elevated supports and grooves that allow popped kernels to move passively to a cooler area, reducing contact with the heat source and minimizing scorching, by utilizing the natural expansion of kernels to lift them out of the oil and onto the supports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the popcorn remains on the heated cooking surface during popping, then the kernels continue to cook efficiently, but the popped kernels become burnt or overcooked
Solution Approach 1:
The cooking surface is segmented into distinct zones: a heated cooking area for unpoped kernels and a cooler support area for popped kernels. This spatial segmentation allows different stages of the popping process to occur simultaneously in different locations, maintaining cooking efficiency while preventing burning of finished popcorn.
Solution Approach 2:
Different regions of the cooking surface have different thermal properties. The cooking area maintains high temperature for efficient kernel popping, while the support area has reduced heat exposure. This local quality differentiation enables popped kernels to be protected from overheating while unpoped kernels continue to cook effectively.
2Object-affected harmful factors
If a stirring mechanism is added to move popped corn off the heat source, then burning is prevented, but device complexity increases
Solution Approach 1:
The cooking surface geometry itself performs the function of separating popped from unpoped kernels. The elevated support area acts as a passive destination for popped kernels, which naturally migrate there due to their expanded size and buoyancy in oil. This self-service mechanism eliminates the need for external stirring mechanisms while still preventing burning.
Solution Approach 2:
The function of moving popped kernels off the heat source is extracted from an active mechanical stirring mechanism and embedded into the passive geometric design of the cooking surface. The elevated support area serves as a dedicated zone that automatically receives and holds popped kernels away from the primary heat source.
3Device complexity
If the cooking surface is made passive without stirring mechanisms, then device complexity is reduced, but popped corn remains in contact with the heat source and burns
Solution Approach 1:
The solution moves from a two-dimensional flat cooking surface to a three-dimensional elevated support structure. By creating vertical elevation, popped kernels are physically lifted off the primary heated plane and positioned on an elevated platform with reduced heat exposure, maintaining simplicity while preventing burning.
Solution Approach 2:
The elevated support area acts as an intermediary zone between the heated cooking surface and the final serving area. Popped kernels are transferred to this intermediate platform that provides thermal buffering, protecting them from direct prolonged heat exposure while the cooking process continues.

Function Achieved in This Case
The design effectively reduces the risk of burning popcorn by minimizing contact with the heat source and oil, eliminating the need for active user intervention to prevent burning, while maintaining efficient cooking of remaining kernels.
Implementation Method 1
produced through the propensity of the corn kernel to explosively expand when heated
Implementation Method 2

AI summary
A popcorn popper including a cooking surface with at least one elevated support and a pattern of contiguous grooves. Each of the contiguous grooves is equal to or larger in width than an average size of an unpopped popcorn kernel and smaller than an average size of a popped popcorn kernel. Each of the elevated supports has a height that is equal to or greater than the average size of an unpopped popcorn kernel. The elevated supports are formed in substantially concentric rings on the cooking surface.
