Solution Overview

Problem

Existing portable and tripod burners face issues with safety, durability, and stability due to complex assembly requirements, exposure of gas lines to wear and tear, and lack of adjustable support for varying pot sizes, leading to potential gas leaks and hazardous pot placement.

Innovation Solution

A propane swivel burner design featuring a welded gas line to the cylinder pipe, a hexagon-shaped grill with interlocking slots for stability, adjustable levels for different pot sizes, and foot stands for enhanced stability, eliminating fittings and providing a seamless construction that reduces leakage risks and improves pot placement safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If multiple fittings are used to assemble the burner legs and gas lines, then the burner can be easily assembled and disassembled, but the gas lines are exposed to wear and tear and leakage risks increase

Engineering Contradiction:
Improveassembly easeVSAvoidgas line safety
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The gas line is integrated directly into the leg structure, eliminating separate gas line fittings. The gas line becomes an inherent part of the leg assembly, reducing the number of connection points and potential leakage sites while maintaining assembly simplicity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The vulnerable gas line fittings are extracted from the assembly and replaced with a welded construction. The gas line is welded directly to the burner body, removing the need for threaded connections and reducing exposure to wear and tear from assembly/disassembly operations.

Inventive Principle:
Principle #2Taking out (Extraction)

2Device complexity

If the burner legs are placed directly on rough surfaces, then the burner structure is simplified, but the legs become dented or punctured reducing stability

Engineering Contradiction:
Improvestructure simplicityVSAvoidleg stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

Protective feet are pre-attached to the bottom of each leg before the burner is put into service. These feet serve as a preliminary protective measure against dents and punctures from rough surfaces, preventing damage before it occurs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Protective feet act as an intermediary element between the leg and the rough surface. This intermediate layer protects the leg from direct contact with damaging surfaces while maintaining the simplicity of the overall structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If the cooking pot is placed directly on the burner legs, then the burner design is simplified, but the pot may slide off creating safety hazards

Engineering Contradiction:
Improvedesign simplicityVSAvoidpot instability
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

A grill grid is introduced as an intermediary between the cooking pot and the burner legs. This grid provides a stable, flat cooking surface that prevents pots from sliding off while maintaining relatively simple burner design.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The support structure transitions from one-dimensional leg support to a two-dimensional grill grid surface. This dimensional change provides broader contact area for pot stability while keeping the overall design simple.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Adaptability or versatility

If the burner structure uses multiple fittings and connections, then assembly is more flexible, but the overall durability and sturdiness are reduced

Engineering Contradiction:
Improveassembly flexibilityVSAvoiddurability
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

Multiple separate components (gas line, leg supports, connections) are merged into integrated welded structures. The gas line is welded to the leg, and the leg supports are welded to the main body, creating a unified structure that is both durable and sufficiently flexible for assembly.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The burner utilizes composite construction combining welded metal structures with integrated gas line pathways. This composite approach creates a sturdy, unified structure that maintains flexibility through design rather than multiple fittings.

Inventive Principle:
Principle #40Composite materials
