Solution Overview

Problem

Conventional cooking ovens lack efficient heat distribution and debris management systems, leading to uneven cooking and potential for debris accumulation, which can result in suboptimal cooking outcomes and maintenance challenges.

Innovation Solution

A cooking oven design featuring a rotating cooking plate with a central radiant heating flame, perimeter multi-flame manifold, and sensors for temperature control, along with a debris collecting channel and removable debris ring, ensures uniform heat distribution and effective debris containment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a conventional cooking oven is used, then the structure is simple, but heat distribution is uneven leading to suboptimal cooking outcomes

Engineering Contradiction:

Improvecooking uniformityVSAvoidoven structure

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The heating system is segmented into multiple independent heat sources: a central radiant heating flame positioned at the central void of the cooking plate, and perimeter multi-flame manifolds positioned at circumferential locations. This segmentation allows each heat source to independently contribute to different zones of the cooking chamber, achieving uniform heat distribution across the cooking surface while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the cooking chamber are provided with different heating characteristics: the central void receives concentrated radiant heating from the central flame for intense localized cooking, while the perimeter regions receive distributed heating from the multi-flame manifolds for even edge cooking. This local differentiation of heating quality resolves the contradiction by providing precisely what each zone needs without requiring complex overall system design.

Inventive Principle:

Principle #3Local quality

2Productivity

If the cooking time is reduced for efficiency, then productivity increases, but cooking quality may deteriorate

Engineering Contradiction:

Improvecooking speedVSAvoidcooking quality

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The rotating cooking plate ensures continuous exposure of all food items to the heating zones, eliminating idle time and ensuring every portion receives consistent radiant heat over the cooking cycle. The rotation mechanism maintains constant useful action by continuously presenting different areas of the food to the optimal heating positions, enabling rapid yet uniform cooking that achieves both high productivity and excellent cooking quality.

Inventive Principle:

Principle #20Continuity of useful action

3Duration of action of stationary object

If debris is allowed to accumulate during cooking, then the system operates continuously without interruption, but maintenance challenges increase

Engineering Contradiction:

Improveoperational continuityVSAvoidmaintenance difficulty

Core Design Contradiction:

Duration of action of stationary objectVSEase of repair

Solution Approach 1:

The debris ring is designed as a removable component that can be easily extracted from the cooking chamber. This extraction capability allows operators to quickly remove accumulated debris without disassembling the entire oven or interrupting the overall system operation. The debris ring acts as a separate, easily removable element that captures debris during cooking, and can be taken out for cleaning without affecting the operational continuity of the main cooking system.

Inventive Principle:

Principle #2Taking out (Extraction)

4Manufacturing precision

If multiple heat sources are added for uniform heating, then cooking quality improves, but energy consumption increases

Engineering Contradiction:

Improveheat distribution uniformityVSAvoidenergy consumption

Core Design Contradiction:

Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

Multiple heat sources are merged into a coordinated heating system where the central radiant flame and perimeter multi-flame manifolds work together synergistically. The central flame provides intense concentrated heat for the core cooking area, while the perimeter manifolds provide distributed heat for edge zones. This merging of heat sources achieves uniform heat distribution across the entire cooking surface more efficiently than using a single high-power source, as each heat source operates in its optimal zone simultaneously.

Inventive Principle:

Principle #5Merging (Combining)
