Movable Lid Heating for Multi-Mode Cooking Appliances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking devices are limited to single cooking operations, requiring multiple devices for various cooking modes, leading to increased costs and storage issues for consumers who want to cook food in different ways.
Innovation Solution
A multifunctional cooking system with a housing and movable lid that allows for multiple cooking modes by controlling airflow and heat distribution, integrating features of pressure cookers and air fryers into a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate cooking devices are used to perform different cooking operations, then each device can be optimized for its specific function, but the cost and storage space requirements increase significantly
Solution Approach 1:
The patent integrates multiple cooking functions (pressure cooking, air frying, baking, roasting, steaming) into a single cooking device. The device includes a removable basket with heating elements that can be positioned in different configurations, allowing one device to replace multiple specialized cooking appliances while maintaining optimized performance for each cooking mode through adjustable component positioning
2Adaptability or versatility
If multiple separate cooking devices are purchased to enable different cooking modes, then cooking flexibility is improved, but the accumulation of devices becomes prohibitive from cost and storage standpoint
Solution Approach 1:
The patent combines the functionality of pressure cookers, air fryers, ovens, and steamers into a single integrated device. By merging these previously separate appliances into one unit with shared components (heating elements, basket, housing), the total volume required for storage is dramatically reduced while maintaining all desired cooking mode flexibilities
3Device complexity
If a single device is designed to perform multiple cooking operations, then cost and storage space are reduced, but the device complexity and operational control become more challenging
Solution Approach 1:
The patent employs dynamically adjustable components including a removable basket that can be positioned at different heights and angles, heating elements that can be activated selectively, and a lid that can be configured in multiple positions. These dynamic adjustments allow the device to optimize its internal configuration for each specific cooking mode, simplifying operation by automatically adapting to the selected function rather than requiring complex manual controls for each mode
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 system enables efficient and versatile cooking by combining multiple functions in one device, reducing the need for multiple appliances and optimizing space and cost, while providing user-friendly operation.
Implementation Method 1
at least one heating element is associated with said lid
Implementation Method 2
in a first cooking mode of the plurality of cooking modes, the at least one heating element is open to airflow between the at least one heating element and the hollow chamber
