Solution Overview

Problem

Existing steam cookers lack features to prevent food from burning and retain nutrients effectively, as they often require constant attention and may use contaminated water, leading to nutrient loss.

Innovation Solution

A double pot hydro steam cooker design where a smaller pot is suspended within a larger one, allowing for steam cooking without direct heat contact, with a lid that seals and directs condensation back into the cooking pot, ensuring purified water and minimizing nutrient loss.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If food is cooked using traditional boiling method, then cooking speed is improved, but nutrients are leached into water and food may burn

Engineering Contradiction:
Improvecooking speedVSAvoidnutrient loss
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The cooking system is segmented into two separate pots: an inner pot for holding food and an outer pot for holding water. This segmentation allows the food to be cooked by steam from the boiling water rather than direct contact with water, preventing nutrient leaching while maintaining cooking speed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Steam acts as an intermediary between the boiling water and the food. The steam transfers heat to cook the food without direct water contact, preventing nutrients from being leached into the water while maintaining efficient heat transfer for quick cooking.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If steam cooker requires constant attention to prevent burning, then food safety is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvefood safetyVSAvoidease of operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The elevated inner pot design allows steam to circulate freely around the food, creating a self-regulating steam cooking environment that prevents burning without requiring constant user attention. The system cooks food evenly through steam circulation, making it hands-off and easy to operate.

Inventive Principle:
Principle #25Self-service

3Device complexity

If water is used for boiling and steaming, then cooking process is simplified, but water contamination and nutrient loss occur

Engineering Contradiction:
Improvecooking process simplicityVSAvoidnutrient loss to water
Core Design Contradiction:
Device complexityVSLoss of substance

Solution Approach 1:

The dual-pot design segments the cooking process into water boiling in the outer pot and steam cooking in the inner pot. This physical separation ensures that food nutrients remain in the inner pot while water boils separately, preventing nutrient leaching into water while maintaining a simple two-pot cooking process.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary

A steam cooker with a first pot and a second pot is provided. The second pot may fit within the first pot and may be suspended above the bottom of the first pot. The bottom of the first pot may be filled with water. Food may be placed within the second pot. A lid may cover the first pot, sealing the water and the second pot within. The first pot may be heated by a fire or stove. The steam from the heated water may sufficiently cook the food. Further, condensation may be collected and water may drip into the second pot. The water is purified due to the boiling process.
