Solution Overview

Problem

Traditional air fryers are limited in functionality, unable to perform frying and baking simultaneously due to a fixed structure, necessitating multiple appliances for different cooking methods.

Innovation Solution

A multifunctional air fryer with a rotatable heating assembly that allows for interchangeable pots, enabling both deep-frying and boiling functions by rotating the heating tube between vertical and horizontal positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the air fryer uses a fixed structure with the heating assembly permanently connected to the body, then the structural stability is improved, but the functional versatility deteriorates as it cannot perform frying and baking simultaneously

Engineering Contradiction:
Improvestructural stabilityVSAvoidfunctional versatility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The heating assembly is made rotatable relative to the fryer body through a rotating mechanism, allowing it to change orientation between facing downward for deep-frying and facing upward for baking/boiling functions. This dynamic adjustment enables one device to perform multiple cooking functions that previously required separate appliances.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If the air fryer uses a fixed heating assembly orientation, then the device complexity is reduced, but the productivity deteriorates as multiple appliances are needed for different cooking methods

Engineering Contradiction:
Improvedevice complexityVSAvoidcooking efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The air fryer is designed with a rotatable heating assembly that can be oriented in different positions to perform multiple cooking functions including deep-frying, pan-frying, and baking/boiling. This multi-functionality allows a single device to replace multiple appliances, improving cooking efficiency without significantly increasing device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the heating assembly is made rotatable to enable multiple functions, then the functional versatility is improved, but the device complexity increases due to additional rotating mechanisms

Engineering Contradiction:
Improvefunctional versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The heating assembly incorporates a rotating mechanism that allows it to change orientation between facing downward and facing upward. This dynamic structure enables the device to perform multiple cooking functions (deep-frying, pan-frying, baking/boiling) while maintaining a relatively simple overall design through the use of a straightforward rotational joint.

Inventive Principle:
Principle #15Dynamics

AI summary

The present invention relates to the technical field of household appliances. Provided is a multifunctional air fryer. In the air fryer, when a heating tube of a heating assembly faces downwards, a pot such as a fryer is placed between the heating tube and a base, a food product is placed in the fryer, and the heating tube emits heat to fry the food product in the fryer, thereby achieving a fryer function; and since the heating assembly is rotatably connected to a rotating assembly and a supporting rod is fixedly connected to the rotating assembly, when the heating assembly rotates the heating tube to face upwards by means of the rotating assembly, a pot such as a frying pan is placed on the heating tube, a food product is placed in the frying pan.
