Solution Overview

Problem

The production of existing grill burners is complicated and expensive due to the need for multiple components and complex assembly processes, particularly the coupling and connection of accessory holder supports to the box-shaped body.

Innovation Solution

A burner design featuring a single, molded metal sheet body with integrated support elements and accessories, such as spark plugs, where the support elements are formed as protrusions and tabs within the sheet, eliminating the need for external fastening systems and simplifying the assembly process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If multiple separate components (box-shaped body and accessory holder supports) are used, then the burner functionality is complete, but the production complexity and assembly time increase

Engineering Contradiction:
Improveproduction complexityVSAvoidnumber of components
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the box-shaped body and accessory holder supports into a single integrated component. The support elements are formed as integral protrusions from the sheet metal body, eliminating the need for separate support components and their associated fastening systems. This reduces the number of parts while maintaining all necessary functional capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sheet metal body serves multiple functions simultaneously: it forms the combustion chamber, provides structural support, and integrates the accessory holder supports. The single component performs what previously required multiple separate parts, simplifying both manufacturing and assembly processes.

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

2Productivity

If multiple separate components with fastening systems are used, then the burner structure is stable, but the assembly time and production costs increase

Engineering Contradiction:
Improveassembly timeVSAvoidassembly complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The support elements are formed as integral parts of the box-shaped body through sheet metal forming operations. This eliminates the need for separate fastening operations (screws, welds, or clips) to attach support brackets, significantly reducing assembly steps and production time while maintaining structural stability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The support elements are pre-formed as integral protrusions during the sheet metal forming process itself. This preliminary formation of support structures eliminates the need for subsequent assembly operations to attach separate support components, streamlining the manufacturing workflow.

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If separate support brackets are used for accessories, then the accessories can be properly positioned, but the production costs and manufacturing steps increase

Engineering Contradiction:
Improvemanufacturing costVSAvoidaccessory positioning
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The accessory holder supports are integrated directly into the burner body as formed protrusions. This eliminates the need for separate support brackets and their associated fastening hardware, reducing material costs and manufacturing complexity while ensuring reliable accessory positioning through the integrated support structure.

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This design reduces production costs and time by integrating support elements into the burner body, making assembly easier and more efficient while maintaining proper functionality.

Implementation Method 1

the first plate-shaped portion (4) defines at its convex area a first perforated surface (4a) for the flow of the combustible fluid outwards

Methodology Applied
Scientific EffectFluid flow:

Implementation Method 2

The spark plug can thus trigger the combustion near the gas-dispensing holes

Methodology Applied
Scientific EffectCombustion: Combustion

Implementation Method 3

each support element (7) is made in a single body with the portions (4, 5) defining the body (2)... the accessory (8), such as a spark plug, is arranged at least partially above the first surface (4a), in order to allow the ignition of the flame at the microholes

Methodology Applied
Scientific EffectElectrical discharge: Electric Spark
