Solution Overview

Problem

Existing devices for fast cooking foods, such as pasta, are mechanically complex, energy-intensive, and prone to food waste due to adhesion to chamber walls, with limited versatility in cooking different types of food.

Innovation Solution

A device with a pressurized boiler and cooking chambers where shut-off valves are operated by pressurized liquid, reducing external energy needs, incorporating jutting elements to prevent food adhesion, and allowing multiple parallel cooking chambers for various food types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If shut-off valves are operated by external motors or mechanical mechanisms, then reliable sealing closure is achieved, but device complexity and energy consumption increase

Engineering Contradiction:
Improvesealing closureVSAvoidmechanical complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The shut-off valve utilizes the pressurized liquid already present in the cooking chamber to actuate the piston and open the valve, eliminating the need for external motors or complex mechanical mechanisms. The system serves itself by using its own operational fluid (pressurized water) to control the valve operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention employs hydraulic principles by using pressurized liquid to move the piston in the shut-off valve. The pressurized water from the cooking chamber directly acts on the piston to open the valve, converting hydraulic pressure into mechanical motion for valve actuation.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Reliability

If traditional shut-off valves are used, then sealing closure is achieved, but energy consumption increases due to external power requirements

Engineering Contradiction:
Improvesealing closureVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system uses the pressurized liquid already present in the cooking chamber to actuate the valve, eliminating the need for external energy sources. The pressurized water serves dual purposes: cooking the food and operating the shut-off mechanism.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The pressurized liquid acts as an intermediary that transfers energy from the cooking chamber to the shut-off valve mechanism, enabling valve operation without direct external energy input. The liquid mediates between the heat source and the mechanical actuation system.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If smooth chamber walls are used, then easy cleaning is achieved, but food adhesion to walls occurs causing waste

Engineering Contradiction:
Improvefood detachmentVSAvoidfood waste
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The cooking chamber walls are provided with local protrusions that create specific local conditions for food detachment. These protrusions are strategically placed on the wall surface to prevent food adhesion at critical locations while maintaining overall chamber functionality.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The protrusions on the chamber walls create curved surfaces that prevent food from adhering flatly to the wall. The curved geometry of the protrusions makes it difficult for food to maintain stable adhesion, facilitating easy detachment and reducing waste.

Inventive Principle:
Principle #14Spheroidality (Curvature)

4Device complexity

If single cooking chamber is used, then device simplicity is maintained, but versatility in cooking different food types is limited

Engineering Contradiction:
Improvedevice simplicityVSAvoidcooking versatility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The cooking system is divided into multiple independent cooking chambers, each capable of processing different food types simultaneously. This segmentation allows for specialized cooking conditions in each chamber while maintaining overall system simplicity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple cooking chambers are provided, each capable of cooking different types of food (pasta, rice, vegetables, etc.). The system achieves multi-functionality through parallel chambers that can be independently operated, allowing versatile cooking capabilities without requiring complex multi-purpose mechanisms.

Inventive Principle:
Principle #6Universality (Multi-functionality)
