Multi-Cavity Sandwich Maker for Coordinated Hot Filling and Toasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Making hot sandwiches at home is a complicated and time-consuming process due to the need for multiple appliances to prepare and cook individual components, which can be difficult to coordinate and clean.
Innovation Solution
A kitchen appliance with a cooking assembly featuring two heated plates and a center ring, allowing for the simultaneous preparation, assembly, and cooking of a hot sandwich within a single device, with movable parts to form multiple cooking cavities for layering and easy removal of the finished sandwich.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple appliances are used to prepare individual sandwich components separately, then each component can be prepared with dedicated functionality, but the overall process becomes complicated and time-consuming
Solution Approach 1:
The patent combines multiple cooking functions (toasting, heating, cooking) into a single sandwich making appliance with multiple heating elements and cavities. This allows all sandwich components to be prepared in one device rather than requiring separate appliances like toasters, microwaves, and skillets, thereby reducing overall device complexity while maintaining versatile cooking capabilities
Solution Approach 2:
The appliance is designed to perform multiple cooking functions simultaneously - toasting bread in outer cavities, cooking fillings in inner cavities, and assembling the complete sandwich. This multi-functional design eliminates the need for multiple specialized appliances while providing dedicated functionality for each cooking task
2Productivity
If multiple appliances are used to prepare sandwich components, then each component can be prepared independently, but coordinating preparation times becomes difficult
Solution Approach 1:
By merging all cooking functions into one appliance with multiple independently controlled heating elements and cavities, the system allows simultaneous preparation of different sandwich components at different temperatures and times. The coordinated control of multiple heating zones enables all components to be ready at the same time without requiring manual coordination between separate appliances
Solution Approach 2:
The appliance features dynamically controllable heating elements in different cavities that can operate independently at different power levels and temperatures. This dynamic control allows optimal cooking conditions for each component type (bread, cheese, meat, vegetables) to be maintained simultaneously, ensuring all components are prepared independently yet ready at the same time
3Adaptability or versatility
If multiple appliances are used for sandwich preparation, then various cooking methods can be applied, but cleaning complexity increases
Solution Approach 1:
The patent integrates multiple cooking surfaces and cavities into a single appliance structure with removable components. This design allows all cooking surfaces to be accessed and cleaned from one location, and removable parts can be easily taken out for washing, significantly reducing cleaning complexity compared to managing multiple separate appliances
Solution Approach 2:
The appliance incorporates removable rings and dividers that segment the cooking cavities for different food items. These segmented components can be easily removed and washed separately, simplifying the cleaning process while maintaining the versatility to prepare different types of sandwiches with various cooking methods
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 appliance simplifies the preparation and cooking of hot sandwiches by integrating multiple cooking functions into one device, ensuring all components are cooked evenly and efficiently, while also reducing cleaning complexity.
Implementation Method 1
a heating element positioned within the bottom housing and configured to transfer thermal energy to the cooking plate

AI summary
An appliance for cooking a food item comprises a bottom housing, a top housing, and a cooking assembly. The cooking assembly comprises a top heated plate, a bottom heated plate, and a center ring therebetween. The top heated plate is selectively movable between (i) an open position and (ii) a closed position in which a top cooking cavity is selectively formed by the top heated plate and the top housing when the top housing is in a closed position. The bottom heated plate is selectively movable between (i) an open position and (ii) a closed position in which a bottom cooking cavity is selectively formed by the bottom housing and the bottom heated plate. A center cooking cavity is selectively formed by the top heated plate, the center ring, and the bottom heated plate when the top and bottom heated plates are in their respective closed positions.
