Solution Overview

Problem

Conventional cooking ovens lack efficient heat distribution and debris management, leading to uneven cooking and potential for food debris to be transferred to lower oven portions, which can cause issues during maintenance and cleaning.

Innovation Solution

A cooking oven with a rotating cooking plate, variable speed drive system, and a debris collecting channel, along with a central radiant heating flame and perimeter multi-flame manifold, controlled by sensors and circuitry to maintain thermal output and prevent debris transfer, is designed to enhance cooking efficiency and cleanliness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a rotating cooking plate is used to transport foodstuffs through the cooking chamber, then cooking efficiency and uniformity are improved, but debris may accumulate on the plate and be transferred to lower oven portions

Engineering Contradiction:

Improvecooking efficiencyVSAvoiddebris transfer

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts the debris collection function from the main cooking plate by adding a separate debris collecting channel at the lower portion of the cooking chamber. This channel captures debris that falls during rotation and prevents its transfer to lower oven portions, thereby resolving the harmful effect while preserving the cooking efficiency benefits of the rotating plate.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The debris collecting channel acts as an intermediary structure between the rotating cooking plate and the lower oven portions. It intercepts debris in transit and provides a designated collection area, preventing harmful debris transfer while allowing the rotating plate to continue its cooking function uninterrupted.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If multiple heat sources are used to improve heat distribution, then cooking uniformity is improved, but device complexity increases

Engineering Contradiction:

Improvecooking uniformityVSAvoidheat source configuration

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The heating system is segmented into multiple independent heat sources positioned at different locations within the cooking chamber. This segmentation allows each heat source to target specific zones, improving overall heat distribution and cooking uniformity while maintaining manageable system complexity through modular configuration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different heat sources are strategically positioned to provide localized heating to specific areas of the cooking chamber. This local quality approach ensures that each region receives appropriate heat intensity, achieving uniform cooking across the entire plate while using a complexity-appropriate number of heat sources.

Inventive Principle:

Principle #3Local quality

3Object-generated harmful factors

If a debris collecting channel is added to prevent debris transfer, then cleanliness is improved, but device complexity increases

Engineering Contradiction:

Improvedebris accumulationVSAvoidstructural components

Core Design Contradiction:

Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The debris collecting channel is merged with the existing cooking chamber structure, utilizing available space and integrating with the rotating plate mechanism. This integration approach adds the debris collection function without requiring entirely separate structural components, thereby improving cleanliness while minimizing the increase in device complexity.

Inventive Principle:

Principle #5Merging (Combining)
