Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional carburetor with a small diameter outflow portion is used, then the structure remains simple and easy to manufacture, but it is difficult to assemble mesh components at predetermined intervals and perpendicular to the flow direction
Solution Approach 1:
The fuel atomization device is divided into multiple components: a body portion, a cap portion, and multiple mesh components. The body portion includes a through-hole with a larger diameter than the outflow portion, providing space for assembling mesh components at predetermined intervals. This segmentation allows complex functionality to be achieved while maintaining ease of assembly through modular construction.
Solution Approach 2:
The invention introduces a dimensional change by creating a through-hole with a larger diameter than the outflow portion of the jet nozzle. This additional spatial dimension provides room for assembling multiple mesh components perpendicular to the fuel flow direction, solving the assembly difficulty caused by the small diameter of the original outflow portion.
2Productivity
If mesh components are added to refine fuel particles, then fuel efficiency improves and exhaust fumes reduce, but the device complexity and assembly difficulty increase
Solution Approach 1:
The fuel refinement function is achieved through multiple separate mesh components (first mesh, second mesh, etc.) that can be independently assembled within the through-hole. Each mesh component contributes to fuel particle refinement, and their modular nature allows for easy installation and maintenance while achieving the desired fuel efficiency improvement.
Solution Approach 2:
The cap portion acts as an intermediary component that secures the mesh components within the through-hole. It includes a securing portion that fits into the through-hole and holds the mesh components in place, facilitating easy assembly and disassembly while maintaining the structural integrity needed for fuel refinement.
3Volume of moving object
If the outflow portion diameter is kept small for compact design, then the carburetor size remains small, but mesh components cannot be properly assembled
Solution Approach 1:
The invention resolves the size constraint by introducing a through-hole with a larger diameter than the outflow portion. This creates an intermediate chamber that provides the necessary space for assembling mesh components, while the overall device size remains compact because the through-hole is integrated into the existing carburetor structure rather than increasing the external dimensions.
Solution Approach 2:
The mesh components are nested within the through-hole of the body portion, which itself is part of the compact carburetor structure. The cap portion then nests over the body portion to secure the assembly. This nested arrangement allows multiple components to be housed in a compact space without increasing the overall device volume significantly.
