Solution Overview

Problem

Existing air fryers have poor steaming effects and user experiences due to traditional frying pans with flat structures that obstruct hot air from reaching the bottom of food, requiring flipping during cooking, and undetachable, hard-to-clean frying basket assemblies with closed bottoms that accumulate grease.

Innovation Solution

A frying pan with arched protrusions and air vents to allow hot air to reach the bottom of food, eliminating the need for flipping, and a detachable frying basket assembly with an oil receiving tray and steamer rack, facilitating easy cleaning and grease management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional flat plate frying pan structure is used, then the structure is simple and easy to manufacture, but hot air cannot reach the bottom of the food due to obstruction, requiring flipping operations during cooking

Engineering Contradiction:
Improvecooking operationVSAvoidfrying pan structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The frying pan bottom is segmented into multiple arched protrusions with air vents, dividing the solid surface into functional zones that allow hot air penetration while maintaining structural integrity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The frying pan transitions from a flat two-dimensional surface to a three-dimensional arched structure, creating vertical space for hot air circulation and enabling heating from multiple directions simultaneously

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a traditional undetachable frying basket assembly with closed bottom is used, then the structure is simple and robust, but grease accumulates at the bottom affecting food taste and cleaning is inconvenient

Engineering Contradiction:
Improvecleaning operationVSAvoidfrying basket assembly structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The frying basket assembly is segmented into detachable components including the basket body, frying pan, and oil receiving tray, allowing separate cleaning and maintenance of each part

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The oil receiving tray is extracted as a separate detachable component from the frying basket assembly, enabling easy removal and cleaning to prevent grease accumulation and maintain food quality

Inventive Principle:
Principle #2Taking out (Extraction)

3Object-generated harmful factors

If a traditional closed bottom frying basket assembly is used, then the structure provides good support and stability, but grease accumulates at the bottom during frying and baking

Engineering Contradiction:
Improvegrease accumulationVSAvoidfrying basket assembly structure
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The oil receiving tray is extracted as a separate functional component to collect and isolate grease, preventing it from contaminating the food while maintaining the structural support of the basket assembly

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The closed bottom structure is converted from a grease-trapping hazard into a beneficial oil collection feature by integrating the detachable oil receiving tray, which collects grease for easy disposal while maintaining cooking functionality

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

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
