Solution Overview

Problem

Existing heating containers for outdoor use require a separate discharge hole for vapor, which complicates manufacturing and can lead to water introduction into the built-in container when the main body is inclined, limiting their effectiveness and convenience.

Innovation Solution

A heating container design featuring a main body and built-in container formed of rigid materials, with a sealing cover that completely seals the built-in container and allows vapor discharge between the main body and built-in container, eliminating the need for a separate discharge hole and incorporating a soft material attachment for secure sealing, a detachable coupling mechanism, and an elastic member for easy removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If a discharge hole is formed in the main body for vapor discharge, then vapor can be discharged from the heating container, but the manufacturing process becomes more complex and water may be introduced into the built-in container when the main body is inclined

Engineering Contradiction:
Improvevapor accumulationVSAvoidmanufacturing process complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The sealing cover integrates both sealing and vapor discharge functions into a single component. The vapor discharge holes are formed in the sealing cover itself rather than requiring separate discharge holes in the main body, combining the sealing function with the vapor discharge function in one element.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Multiple vapor discharge holes are distributed across the sealing cover to provide sufficient vapor discharge pathways without requiring a single large or complex discharge structure. This simplified approach replaces the need for complex single-hole designs.

Inventive Principle:
Principle #26Copying

2Object-generated harmful factors

If a discharge hole is formed in the main body, then vapor can be discharged, but water may be introduced into the built-in container when the main body is inclined

Engineering Contradiction:
Improvevapor accumulationVSAvoidwater intrusion prevention
Core Design Contradiction:
Object-generated harmful factorsVSReliability

Solution Approach 1:

The sealing cover combines sealing and vapor discharge functions, positioning the vapor discharge holes in a location that maintains sealing integrity even when the container is inclined, preventing water intrusion while ensuring vapor escape.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sealing cover provides localized sealing quality at the interface between the built-in container and main body, with vapor discharge holes strategically positioned to maintain reliability under various orientations.

Inventive Principle:
Principle #3Local quality

3Device complexity

If the built-in container is simply inserted into the main body, then the structure is simple, but water may be introduced into the built-in container when the main body is inclined

Engineering Contradiction:
Improvestructural complexityVSAvoidsealing reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The sealing cover integrates sealing and vapor discharge functions, providing reliable sealing without requiring complex additional structures. The vapor discharge holes are formed directly in the sealing cover, eliminating the need for separate discharge mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of operation

If the sealing cover is coupled to the main body with a detachable coupling mechanism, then the built-in container can be easily removed, but the structure becomes more complex

Engineering Contradiction:
Improvebuilt-in container removalVSAvoidcoupling mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The detachable coupling mechanism allows the sealing cover to be easily attached and detached from the main body, enabling simple removal and installation operations. The coupling structure provides secure connection during use but allows easy separation when needed.

Inventive Principle:
Principle #15Dynamics

AI summary

Provided is a heating container simply cooks or heats foods using a heater without help of a heating device required for cooking during the outdoor leisure activation such as climbing or fishing. The heating container includes a main body in which a heater is inserted and water is poured, a built-in container inserted into the main body, the built-in container providing a space for cooking foods therein, and a sealing cover sealing an opened upper portion of the built-in container, the sealing cover being coupled to the main body when the built-in container is sealed. Each of the main body and the built-in container is formed of a rigid material, and vapor generated when water within the main body is boiled is discharged between the main body and the built-in container to the outside.
