Solution Overview
Problem
Contaminations from cooling lubricants and shavings in mechanical machining of engine components, such as cylinder heads, pose a risk of engine damage due to disruptions in downstream assembly processes and technical functionality issues.
Innovation Solution
A nozzle apparatus with a slit-shaped nozzle opening and a hollow body extending into the nozzle chamber, which supports the apparatus body and allows for the generation of a fluid stream with high flow velocity and large mass flow rate, is used for flood-washing workpieces in a cleaning container filled with a liquid cleaning medium, enabling effective removal of contaminants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a conventional nozzle is used for cleaning workpieces, then the cleaning process is simple, but the fluid stream has insufficient flow velocity and mass flow rate to effectively remove contaminants
Solution Approach 1:
The hollow body is extended into the nozzle chamber, creating a nested structure where the hollow body is positioned within the nozzle chamber. This nesting arrangement allows the hollow body to support the apparatus body while the nozzle opening generates the fluid stream, achieving high flow velocity without requiring a complex external support structure.
Solution Approach 2:
The nozzle apparatus is divided into distinct functional segments: the hollow body for structural support, the nozzle chamber for fluid containment, and the nozzle opening for fluid ejection. This segmentation allows each component to be optimized independently, achieving high fluid velocity while maintaining structural integrity.
2Productivity
If a high-flow velocity fluid stream is generated to remove contaminants, then cleaning effectiveness is improved, but turbulence and mechanical stress increase
Solution Approach 1:
The hollow body provides localized structural support at the critical region where the fluid stream is generated. By positioning the hollow body within the nozzle chamber, structural reinforcement is applied precisely where needed to handle high flow velocities without causing excessive turbulence or mechanical stress throughout the entire apparatus.
3Adaptability or versatility
If the nozzle geometry is made adjustable to optimize cleaning for different surfaces, then versatility is improved, but device complexity increases
Solution Approach 1:
The nozzle apparatus incorporates adjustable geometry through movable components that allow the nozzle opening configuration to be changed. This dynamic adjustment capability enables optimization of the fluid stream for different workpiece surfaces and contaminant types while maintaining a relatively simple overall structure through the hollow body support system.
