Solution Overview

Problem

Classical outdoor stoves require a separate pot or kettle for heating water, which is inefficient and time-consuming, and the fuel flow control is not easily manageable.

Innovation Solution

A portable heating chamber with a fixation mechanism for securing a container, compartments for liquid, a pressure compensation valve, and an outlet for releasing heated liquid, allowing for efficient heating and controlled dispensing of water for preparing beverages or food.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a separate pot or kettle is used for heating water, then the stove structure is simple, but the preparation time increases and efficiency decreases

Engineering Contradiction:
Improvewater heating efficiencyVSAvoidstove structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent integrates the water container directly into the heating chamber of the stove, merging two previously separate components (stove and pot) into a single integrated unit. This eliminates the need for external pots or kettles, thereby reducing preparation time and improving heating efficiency while maintaining structural simplicity through functional integration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The heating chamber is designed to serve multiple functions: it acts as both the combustion chamber and the water heating container. The integrated design allows the same structure to perform both fuel combustion and water heating tasks simultaneously, improving productivity without significantly increasing device complexity.

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

2Loss of time

If a separate pot or kettle is used, then the stove is easier to manufacture, but it takes more time to prepare hot water

Engineering Contradiction:
Improvewater preparation timeVSAvoidstove manufacturing simplicity
Core Design Contradiction:
Loss of timeVSEase of manufacture

Solution Approach 1:

By combining the water container and heating chamber into a single integrated structure, the patent eliminates the time required to separately handle and heat water in external containers. The integrated design reduces water preparation time while maintaining manufacturing simplicity through unified construction rather than assembly of multiple separate components.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If classical outdoor stoves are used with separate pots, then the device is simpler, but the fuel flow control is not easily manageable

Engineering Contradiction:
Improvefuel flow controlVSAvoidstove structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The integration of the water container within the heating chamber allows for direct control of fuel flow to the exact location where water is heated. This unified design improves ease of operation by enabling precise fuel flow management without requiring separate control mechanisms for external pots, while avoiding additional structural complexity through functional consolidation.

Inventive Principle:
Principle #5Merging (Combining)
