Solution Overview

Problem

The existing methods for producing panigacci are inefficient, leading to inconsistent cooking times, uneven heating, and difficulties in achieving a high volume of freshly cooked products, as they rely on manual dosing and heating of terracotta dishes, resulting in variations in quality and flavor.

Innovation Solution

An automated apparatus using rotating conveyor belts with terracotta dishes that are heated in an oven, allowing for continuous production with precise batter dosing and pressure-controlled cooking, ensuring homogeneous cooking while maintaining traditional cooking methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual dosing and heating of terracotta dishes is used, then traditional cooking method is maintained, but production efficiency is low and cooking consistency is poor

Engineering Contradiction:
Improveproduction efficiencyVSAvoidautomation level
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The system allows terracotta dishes to be automatically conveyed through the oven and dosed with batter without manual intervention. The conveyor belt system enables the dishes to move through heating and cooking zones autonomously, eliminating the need for manual dosing and heating while maintaining traditional cooking methods.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical operations (hand-dosing, manual dish handling) are replaced with an automated conveyor belt system that mechanically transports terracotta dishes through controlled heating zones. The system uses mechanical conveyance instead of human labor to achieve consistent cooking results.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If terracotta dishes are heated individually over flame, then traditional method is preserved, but heating uniformity is poor and cooking time varies

Engineering Contradiction:
Improvecooking consistencyVSAvoidheating system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The heating system is divided into multiple independent heating zones along the conveyor belt path. Each zone can be controlled separately to ensure uniform heating of terracotta dishes as they pass through, eliminating the variability of individual flame heating while maintaining traditional cooking principles.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses a dynamic conveyor belt that moves dishes through controlled heating zones at regulated speeds. This dynamic approach allows precise control of residence time in each heating zone, ensuring uniform cooking without the inconsistencies of static manual heating methods.

Inventive Principle:
Principle #15Dynamics

3Extent of automation

If conveyor belt with burners under belt is used, then automation is achieved, but traditional cooking method is compromised and heating uniformity is poor

Engineering Contradiction:
Improveautomation levelVSAvoidtraditional cooking method integrity
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The conveyor belt acts as an intermediary that transports terracotta dishes through the oven without direct contact between burners and dishes. Heating occurs through thermal radiation and convection from the oven environment, preserving the traditional method of heating terracotta dishes while achieving automation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of placing burners under the conveyor belt to heat from below, the system inverts the approach by using an oven environment that heats the terracotta dishes from all sides through radiation and convection. This maintains the traditional heating principle while achieving automated processing.

Inventive Principle:
Principle #13The other way round (Inversion)

4Productivity

If more terracotta dishes are processed simultaneously, then production volume increases, but heating uniformity and temperature control deteriorate

Engineering Contradiction:
Improveproduction volumeVSAvoidtemperature uniformity
Core Design Contradiction:
ProductivityVSTemperature

Solution Approach 1:

The system transitions from processing dishes in a single batch to continuous processing along the conveyor belt's length. Multiple dishes are processed simultaneously at different positions along the conveyor, each receiving uniform heating from the oven environment, thereby increasing production volume while maintaining temperature uniformity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
