Solution Overview

Problem

Existing cooking appliances are inefficient in simultaneously preparing different foods with varying degrees of doneness and preparation methods, often requiring multiple containers and compromising on optimal cooking results, especially for portioned ready meals.

Innovation Solution

A cooking appliance with a cooking space divided into multiple independently controlled cooking zones, allowing for the use of different cooking agents and methods within the same zone, such as steam, grilling, or microwaving, without the need for physical partitions, enabling flexible and optimal preparation of various foods without repositioning the vessel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If different foods are placed in different containers on various levels of the cooking space, then different foods can be prepared simultaneously, but the device complexity and size increase

Engineering Contradiction:

Improvesimultaneous preparation of different foodsVSAvoiddevice complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The cooking chamber is divided into multiple cooking zones with different cooking means (steam, grill, microwave) to prepare different foods simultaneously in the same vessel, eliminating the need for multiple containers and levels

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A single cooking chamber is designed to accommodate multiple cooking means (steam generator, grill, microwave) that can operate independently or simultaneously, allowing one device to perform multiple cooking functions

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple cooking means are added to provide different preparation types, then cooking versatility improves, but manufacturing costs and device size increase

Engineering Contradiction:

Improvecooking versatilityVSAvoidmanufacturing costs

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Multiple cooking means (steam generator, grill, microwave) are merged into a single cooking chamber, allowing different preparation types to be applied to different foods in the same vessel without requiring separate appliances

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Different cooking means are arranged in different spatial dimensions within the cooking chamber (steam from below, grill from above, microwave throughout), allowing simultaneous operation without increasing external device size

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Volume of moving object

If cooking zones are arranged one below the other, then vertical space is utilized, but the vessel must be repositioned for different cooking methods

Engineering Contradiction:

Improvevertical space utilizationVSAvoidvessel repositioning

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The cooking chamber is segmented into multiple independent cooking zones (steam zone, grill zone, microwave zone) that can operate simultaneously on different foods in the same vessel, eliminating the need to reposition the vessel

Inventive Principle:

Principle #1Segmentation

AI summary

The invention relates to a cooking device having a cooking chamber for preparing dishes, a controller, and at least one cooking means (11, 12, 13), which, in the cooking chamber, acts on the dishes to be prepared in accordance with the controller. The cooking chamber has a receptacle for the dishes to be prepared, which has a fixed rotational position. The cooking chamber is divided into at least two cooking zones (10), wherein each cooking zone (10) has a separate cooking means (11, 12, 13), which can be controlled independently of the cooking means (11, 12, 13) of the at least one other cooking zone (10). The at least two cooking zones (10) lie next to each other on a plane of the cooking chamber and are mutually open. At least one of the cooking zones (10) has more than one cooking means (11, 12, 13), wherein at least one first cooking means of said cooking means (11, 12, 13) of the same cooking zone (10) corresponds to a different preparation type than a second cooking means of said cooking means (11, 12, 13) of the same cooking zone (10). Said device enables fast and simple joint preparation of foods that are in different cooking states.
