Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional welding methods with radially outwardly bent flange areas are used to connect combustion chamber elements, then the connection stability is improved, but the device complexity and assembly complexity increase due to required deformations and multi-step processes
Solution Approach 1:
The combustion chamber is divided into multiple elements that can be connected through laser welding, allowing for modular assembly without complex deformations of flange areas. Each element maintains its structural integrity while enabling simplified connection processes.
Solution Approach 2:
Traditional mechanical welding processes are replaced with laser welding technology, which eliminates the need for radially bent flange areas and complex deformation steps. The laser welding process directly joins elements through precise energy input, reducing assembly complexity while maintaining connection stability.
2Volume of moving object
If radially staggered arrangement of combustion chamber elements is implemented, then the compactness and simplicity of design are improved, but the manufacturing precision requirements increase for laser welding alignment
Solution Approach 1:
The combustion chamber elements are arranged in a radially staggered configuration, utilizing radial positioning to achieve compactness. This dimensional arrangement allows elements to overlap axially while maintaining precise laser welding alignment through the radial offset, effectively combining compact design with manufacturability.
3Reliability
If axial overlap of circumferential walls is used to connect combustion chamber elements, then the leak-proof connection is improved, but the ease of manufacture decreases due to laser welding requirements
Solution Approach 1:
Traditional mechanical connection methods are replaced with laser welding to join circumferential walls in axial overlap. The laser welding process creates seamless, leak-proof joints without requiring complex mechanical fastening systems, improving reliability while maintaining ease of manufacture through automated processing.
