Solution Overview

Problem

Existing steam cooking machines for food products, such as pasta and cous cous, are inefficient in terms of heat and steam usage, as steam energy is dispersed before it can effectively cook the products, leading to suboptimal cooking performance.

Innovation Solution

A steam cooking machine with a containment plane above the conveyor belt to keep steam tangent to the food products, reducing energy dispersion and enhancing cooking efficiency by maintaining heat contact throughout the cooking process, which can be heated for additional performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If steam is generated and passed through the conveyor belt from bottom upwards, then the food products are cooked, but the steam disperses its energy away from the product in the upper chamber leading to inefficient cooking

Engineering Contradiction:
Improvesteam energy dispersionVSAvoidcooking efficiency
Core Design Contradiction:
Loss of energyVSProductivity

Solution Approach 1:

The invention extracts and removes the harmful energy dispersion from the system by introducing a containment plane that redirects steam flow. The plane captures the dispersing steam in the upper chamber and forces it to remain in contact with the product, thereby taking out the energy loss element and converting it into useful cooking energy.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The containment plane acts as an intermediary element between the steam and the food product. It mediates the steam flow by forcing the steam to remain tangent to and in contact with the product surface, ensuring efficient heat transfer while preventing the steam from dispersing energy away from the cooking zone.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the containment plane is placed throughout the whole conveyor belt length, then steam contact efficiency is maximized, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improvecooking efficiencyVSAvoidstructure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention applies local quality by placing the containment plane only in the initial portion of the conveyor belt where steam contact is most critical for cooking efficiency. This localized approach maintains the beneficial steam containment effect where needed most while avoiding the complexity and cost of implementing it throughout the entire belt length.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention uses partial action by implementing the containment plane only in the initial portion of the cooking chamber rather than throughout the entire length. This partial implementation is sufficient to achieve the primary goal of improving steam contact efficiency without the excessive complexity of a full-length implementation.

Inventive Principle:
Principle #16Partial or excessive action

3Volume of moving object

If the vertical distance between the conveyor belt and containment plane is increased, then more space is available for steam flow, but the steam may disperse and lose contact with the product

Engineering Contradiction:
Improvesteam flow spaceVSAvoidheat energy dispersion
Core Design Contradiction:
Volume of moving objectVSLoss of energy

Solution Approach 1:

The invention applies dynamics by making the containment plane height adjustable rather than fixed. This allows the vertical distance between the conveyor belt and containment plane to be dynamically optimized - providing sufficient space for steam flow while maintaining the plane's ability to redirect and contain steam contact with the product, thereby preventing energy dispersion.

Inventive Principle:
Principle #15Dynamics
