Solution Overview

Problem

Conventional cooking instruments lack the capability to systematically and consistently produce complex meals with precision and speed, requiring multiple instruments and manual intervention due to their inability to handle multiple cooking zones with different heating sequences.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single cooking instrument is used, then device complexity is reduced, but the ability to produce complex meals with precision and speed deteriorates

Engineering Contradiction:

Improvenumber of cooking instrumentsVSAvoidcooking speed and precision

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The cooking chamber is divided into multiple independently controllable heating zones, each with its own heating elements and temperature control. This allows different portions of food to be cooked simultaneously with different heating sequences and parameters, enabling complex meals to be prepared in a single instrument with precision and speed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cooking instrument implements dynamic heating sequences where each zone can independently adjust its heating parameters throughout the cooking process. The system can switch between different heating modes (e.g., preheating, cooking, resting) in different zones simultaneously, allowing complex meals to be prepared efficiently in one instrument.

Inventive Principle:

Principle #15Dynamics

2Manufacturing precision

If multiple heating sequences are applied simultaneously to different food portions, then cooking precision is improved, but device complexity increases

Engineering Contradiction:

Improvecooking precisionVSAvoidheating system configuration

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The heating system is segmented into multiple independent zones with separate heating elements, controllers, and sensors. Each zone can execute its own heating sequence independently, allowing precise control over different food portions without requiring a single complex centralized control system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each heating zone is designed with universal functionality, capable of performing all necessary cooking operations (heating, holding, cooling) independently. This modular approach allows the system to handle multiple heating sequences simultaneously while keeping individual zone complexity manageable.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If manual intervention is required to monitor and adjust cooking, then cooking adaptability is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvecooking adaptabilityVSAvoidhuman intervention required

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Each heating zone is equipped with sensors that continuously monitor temperature, humidity, and cooking progress. This feedback is fed to the control system, which automatically adjusts heating parameters to maintain optimal cooking conditions, eliminating the need for manual monitoring while preserving cooking adaptability.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The cooking system performs self-adjustment through automated control algorithms that respond to sensor feedback. The instrument independently manages heating sequences, temperature regulation, and cooking timing for multiple zones simultaneously, providing adaptability without requiring human intervention.

Inventive Principle:

Principle #25Self-service

AI summary

Several embodiments include a cooking instrument. The cooking instrument can select a food cooking recipe and identify relative areas in a cooking chamber to place at least two portions of food. The relative areas would match the food cooking recipe. The cooking instrument can display information associated with an instruction to place the at least two portions of food over the relative areas. The cooking instrument can then determine a heating sequence in accordance with the food cooking recipe and control, based on the heating sequence, a heating system to directionally transfer heat under different heating characteristics respectively to the at least two portions of the food at the identified relative areas in the cooking chamber.
