Air pressure cooker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pressure cookers cannot simultaneously perform the functions of an air fryer and an electric pressure cooker, limiting food variety and taste options for users.
Innovation Solution
An air pressure cooker design that combines air fryer and electric pressure cooker functions by incorporating a modular upper cover with interchangeable accessories, including a heat insulation cover, motor, fan blades, heating tubes, and valves, allowing for switching between air fryer and pressure cooker modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional pressure cooker design is used, then the device structure is simple, but it cannot simultaneously perform air fryer and pressure cooker functions
Solution Approach 1:
The patent integrates both air fryer and pressure cooker functions into a single device. The upper cover can be configured with either air frying components (heating tube, fan blades) or pressure cooking components (sealing ring, steam vent), allowing one device to perform multiple cooking functions that previously required separate appliances
Solution Approach 2:
The upper cover is designed as a separable module that can be removed and replaced. The sealing ring and steam vent are positioned on the upper cover, allowing users to detach the entire upper cover assembly and replace it with an alternative configuration, enabling function switching without complex internal mechanisms
2Adaptability or versatility
If air fryer and pressure cooker functions are combined, then food variety and taste options are improved, but the device complexity increases
Solution Approach 1:
The device allows dynamic reconfiguration of the upper cover based on cooking needs. Users can remove and replace the upper cover assembly to switch between air frying and pressure cooking modes, providing functional adaptability without requiring complex automated switching mechanisms or multiple fixed configurations
3Adaptability or versatility
If interchangeable accessories are added to enable function switching, then the adaptability is improved, but the ease of operation deteriorates
Solution Approach 1:
The upper cover is designed as a complete removable module that includes all necessary components for a specific cooking function (sealing ring, steam vent, or air frying elements). This segmentation allows users to switch functions by simply removing and replacing the entire upper cover assembly rather than manipulating multiple small components, maintaining operational simplicity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
