Problem

Conventional cooking devices are limited to single cooking operations, requiring multiple devices for various cooking modes, which leads to increased cost and storage issues for consumers who want to cook food in different ways.

Innovation Solution

A multifunctional cooking system that integrates multiple cooking modes into a single device, featuring a housing with a movable lid, multiple heating elements, and a rotational air movement device, allowing for conductive and convective cooking modes, along with a secondary lid for pressure cooking and air frying capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate cooking devices are used for different cooking operations, then each device can be optimized for its specific function, but the cost and storage space required increase significantly

Engineering Contradiction:
Improvecooking mode versatilityVSAvoidnumber of devices
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cooking device integrates multiple cooking functions (pressure cooking, air frying, baking, roasting, steaming, sautéing) into a single device by combining a heating element, an air movement device, and a controller that can operate in different modes, eliminating the need for multiple separate cooking devices

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

Solution Approach 2:

The patent merges the functionality of a pressure cooker and an air fryer (and potentially other cooking devices) into one unified system by integrating the heating element, air movement device, and control system into a single housing with a shared cooking chamber

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If a single device performs multiple cooking operations, then cost and storage space are reduced, but the device complexity and control difficulty increase

Engineering Contradiction:
Improvenumber of devicesVSAvoidoperation simplicity
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The controller automatically selects and executes appropriate cooking parameters and sequences based on the selected cooking mode, reducing the need for manual intervention and making the complex multi-function device easy to operate

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The unified control system manages multiple cooking functions through a single interface, allowing users to select from different cooking modes (pressure cooking, air frying, baking, etc.) without needing to understand the complex underlying mechanisms of each function

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