Solution Overview

Problem

Traditional stone pizza ovens face issues with uneven heat distribution, cumbersome pizza repositioning, safety hazards from charcoal combustion, smoke contamination, and difficult charcoal residue management, leading to suboptimal baking quality and increased production costs.

Innovation Solution

A controllable rotating pizza oven with a baking chamber and combustion chamber, featuring a rotating tray driven by a drive shaft and control lever, which allows for 180-degree rotation of the baking pan, along with a smoke exhaust system and temperature detector, to ensure even heating, reduce manual adjustments, and enhance safety and cleanliness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the stone is fixed in the baking chamber, then the structure is simple, but the heat distribution is uneven and the pizza cannot be baked evenly

Engineering Contradiction:

Improveheat distributionVSAvoidstructure complexity

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The patent transforms the fixed stone into a rotatable baking pan that can rotate 180 degrees or 360 degrees within the baking chamber. This dynamic structure allows the pizza to be exposed to different temperature zones during baking, achieving even heat distribution without requiring a complex multi-zone heating system.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The baking chamber is effectively divided into different temperature zones (high temperature zone near the combustion chamber and low temperature zone away from it). The rotatable baking pan allows the pizza to move between these zones, utilizing the natural temperature gradient to achieve even baking.

Inventive Principle:

Principle #1Segmentation

2Temperature

If the pizza is manually re-positioned multiple times, then the baking quality can be improved, but the operation becomes cumbersome and baking time increases

Engineering Contradiction:

Improvebaking qualityVSAvoidbaking time

Core Design Contradiction:

TemperatureVSLoss of time

Solution Approach 1:

Instead of manually removing and repositioning the pizza multiple times, the patent implements a rotatable baking pan that can automatically rotate the pizza 180 degrees or 360 degrees within the chamber. This continuous dynamic adjustment eliminates the need for repeated manual interventions, maintaining baking quality while reducing total baking time.

Inventive Principle:

Principle #15Dynamics

3Shape

If the combustion chamber is behind the baking chamber, then the layout is compact, but opening the baking chamber causes fire to burn backwards creating safety hazards

Engineering Contradiction:

Improvelayout compactnessVSAvoidsafety

Core Design Contradiction:

ShapeVSReliability

Solution Approach 1:

The patent divides the oven into functionally independent sections: the combustion chamber and baking chamber are separated with independent openings. The combustion chamber has its own opening on the side away from the baking chamber, preventing fire from burning backwards when the baking chamber is opened. This segmentation maintains compact layout while ensuring safety.

Inventive Principle:

Principle #1Segmentation

4Temperature

If charcoal is burned for heating, then high temperature can be achieved, but smoke and dust contaminate the pizza and require frequent cleaning

Engineering Contradiction:

Improveheating temperatureVSAvoidsmoke and dust contamination

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the harmful combustion process from the baking chamber by providing a separate opening for the combustion chamber on the side away from the baking chamber. This allows smoke and dust to be vented externally rather than contaminating the pizza in the baking chamber, while still achieving high temperatures through charcoal combustion.

Inventive Principle:

Principle #2Taking out (Extraction)
