Solution Overview

Problem

Existing electric steam cookers lack control over steam release and are not adaptable to different container sizes, making them inefficient for heating and steaming food economically.

Innovation Solution

A steam cooker accessory with a steam generator and a removable ring that surrounds the steam generator, allowing for adjustable sizes and a water reservoir for quicker steam production, along with a notch for easy steam exhaust, facilitating easier cleaning and adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a steam generator is designed with a fixed structure, then it is simple to manufacture, but it cannot adapt to different container sizes

Engineering Contradiction:
Improveadaptability to different container sizesVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The steam generator is divided into separate modular components: a base unit with heating element and water reservoir, and removable ring attachments of different sizes. This segmentation allows the same base unit to work with multiple container sizes by simply changing the ring attachment, resolving the contradiction between adaptability and structural simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base steam generator unit is designed with universal functionality to work with multiple container sizes through interchangeable ring attachments. The same heating mechanism and water reservoir serve all container configurations, achieving adaptability without increasing the complexity of the core steam generation system.

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

2Ease of operation

If a duct is provided for steam exhaust, then steam can be vented effectively, but it is difficult to clean

Engineering Contradiction:
Improveease of cleaningVSAvoidsteam accumulation
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The exhaust function is extracted from the steam generator body and integrated into the removable ring attachment. The exhaust opening is formed directly in the ring structure itself, allowing the ring to be removed and cleaned easily without disassembling ducts or channels within the main generator body.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The ring attachment with its integrated exhaust opening serves as a self-contained unit that can be easily removed, rinsed, and reattached. The simple open structure of the ring with exhaust opening requires no complex disassembly for cleaning, making maintenance straightforward and efficient.

Inventive Principle:
Principle #25Self-service

3Productivity

If a large water reservoir is used, then steam production is sustained longer, but it takes longer to heat the water and produce steam

Engineering Contradiction:
Improvesteam production speedVSAvoidsteam production duration
Core Design Contradiction:
ProductivityVSDuration of action of moving object

Solution Approach 1:

The system dynamically adapts water quantity to cooking needs through interchangeable reservoir sizes. For quick steaming tasks, a small reservoir provides rapid heating. For longer cooking sessions, a larger reservoir extends duration. This dynamic configuration allows optimization of either speed or duration based on specific cooking requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The water reservoir capacity parameter can be changed by selecting different sized reservoirs or partial filling options. This parameter adjustment allows the user to optimize the balance between heating time and steam production duration according to the specific cooking task at hand.

Inventive Principle:
Principle #35Parameter changes
