Modular Pizza Oven with Segmented Baking Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial pizza ovens are heavy, difficult to install, and maintain, leading to high shipping and installation costs, and they often produce uneven heating due to large size and volume, resulting in inconsistent baking. Additionally, existing burner systems are inefficient in maintaining desired temperatures, and flame detection systems are prone to false signals from contamination, causing operational interruptions.
Innovation Solution
A modular pizza oven design with a conveyor belt system that allows for easy assembly and disassembly, featuring a jam detection system, adjustable conveyor speed and air circulation for even baking, and a burner arrangement that combines the efficiency of on/off and modulating systems to maintain consistent temperatures, along with a flame detection system positioned to minimize contamination effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-unit pizza oven is constructed and shipped to the customer, then the oven can be delivered to the customer, but the shipping and installation costs are high due to the large size and weight
Solution Approach 1:
The pizza oven is divided into multiple separate modules that can be shipped individually and assembled at the installation site. This segmentation reduces the weight and size of each individual shipping unit, lowering shipping costs and making installation more manageable without requiring specialized heavy machinery installation services.
2Strength
If the pizza oven is constructed as a single unit with riveting, tech screws, and welding, then the oven is structurally sound, but the oven cannot be easily disassembled for repair
Solution Approach 1:
The oven is designed as modular units with standardized connection interfaces that allow for easy disassembly and reassembly. This enables individual modules to be replaced or repaired without dismantling the entire oven structure, maintaining structural integrity while significantly improving ease of repair and reducing service call costs.
3Productivity
If the pizza oven is made large to accommodate commercial use, then the oven can handle high volume, but uneven heating occurs due to the large size and volume
Solution Approach 1:
The large baking chamber is divided into multiple smaller modular sections, each with its own heating elements and air circulation systems. This segmentation allows each module to maintain uniform temperature distribution and heating consistency, while the combined modular system provides the total baking capacity needed for commercial high-volume operations.
Solution Approach 2:
Each modular section is equipped with localized heating controls and air circulation mechanisms tailored to its specific dimensions and baking requirements. This ensures that each local zone achieves optimal and uniform baking results, preventing the uneven heating that occurs in large monolithic ovens where temperature distribution is difficult to control consistently across the entire volume.
4Measurement precision
If the flame detection system is positioned close to the burner, then the detection is sensitive, but false signals occur due to contamination
Solution Approach 1:
An intermediary optical channel or protective barrier is introduced between the flame detection sensor and the burner environment. This intermediary allows the sensor to detect flame presence accurately while protecting it from direct exposure to contamination, oil, and heat that would otherwise cause false signals and reduce detection reliability.
