Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a fixed combustion chamber structure is used, then structural stability is improved, but maintenance complexity increases due to dust accumulation

Engineering Contradiction:
Improvestructural stabilityVSAvoidmaintenance complexity
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The combustion chamber is divided into a combustion chamber main body and a separate burner head that can be detached. The burner head includes the cylindrical portion with nozzles and can be removed as a separate unit for maintenance, allowing dust accumulation issues to be addressed without dismantling the entire combustion chamber structure.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If multiple nozzles are integrated into a single burner head, then device complexity is reduced, but ease of maintenance worsens due to dust accumulation in integrated structures

Engineering Contradiction:
Improvedevice complexityVSAvoidease of maintenance
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The burner head integrating fuel nozzle, combustion supporting gas nozzle, and processing gas nozzle is designed as a detachable unit. This segmentation allows the integrated nozzle assembly to be easily removed and replaced as a single unit, maintaining operational simplicity while enabling straightforward maintenance by eliminating the need to disassemble individual nozzle components.

Inventive Principle:
Principle #1Segmentation
