Solution Overview

Problem

Portable propane stoves lack a compact and stable cooking solution for outdoor use, as existing collapsible tables are often too large for easy transport and may pose safety risks due to instability on uneven surfaces.

Innovation Solution

A compact propane stove with an integrated roll table design, where the table surface rolls around the stove with legs stored inside, providing a portable, stable, and space-efficient cooking solution that can be easily assembled and disassembled without tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a portable table is brought for cooking, then stability and safety are improved, but portability and storage space deteriorate

Engineering Contradiction:

ImprovestabilityVSAvoidportability

Core Design Contradiction:

ReliabilityVSLength of moving object

Solution Approach 1:

The table surface is designed to roll around and enclose the propane stove, with the table legs storing inside the outer circumference defined by the table surface. This nesting configuration allows the stable table structure to be compacted into a small portable unit that fits within the stove's footprint.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The table and stove are merged into a single integrated unit where the table surface rolls around the stove assembly. This combination eliminates the need to transport separate table and stove items, achieving both stability (through the table) and portability (through integration) simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

2Length of moving object

If a collapsible table with folding legs is used, then portability is improved, but stability and safety deteriorate

Engineering Contradiction:

ImproveportabilityVSAvoidstability

Core Design Contradiction:

Length of moving objectVSReliability

Solution Approach 1:

The table employs dynamic leg mechanisms that can be quickly deployed from a compact stored position to a fully extended stable position. The legs transition from a retracted state during transport to an extended state during use, providing stability only when needed while maintaining portability during transport.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The table legs are pre-positioned in a compact configuration for transport, then quickly deployed to a stable configuration before cooking begins. This preliminary preparation ensures the table is ready for stable use without requiring complex assembly during cooking setup.

Inventive Principle:

Principle #10Preliminary action

3Length of moving object

If a roll table is used, then portability and storage space are improved, but device complexity increases

Engineering Contradiction:

ImproveportabilityVSAvoiddevice complexity

Core Design Contradiction:

Length of moving objectVSDevice complexity

Solution Approach 1:

The table surface is constructed as a flexible rollable element that can be wound around the stove. This flexible shell design enables compact storage while maintaining a rigid flat surface when deployed, avoiding the need for complex mechanical folding mechanisms.

Inventive Principle:

Principle #30Flexible shells and thin films
