Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional nozzles with static geometry are used, then the structure is simple, but the spatial distribution control and metering precision are insufficient
Solution Approach 1:
The nozzle geometry is made adjustable through a mechanism that allows dynamic modification of the emergence shape and gap size. This enables precise control over spatial distribution and metering while maintaining operational flexibility, directly resolving the contradiction between precision and complexity.
2Productivity
If higher pressure is applied to increase discharge rate, then the productivity increases, but the noise emission and energy consumption increase
Solution Approach 1:
The system optimizes the relationship between pressure, flow rate, and nozzle geometry by allowing adjustment of emergence parameters. This enables achieving required discharge rates with lower pressure differentials, thereby reducing noise emission and energy consumption while maintaining productivity.
3Reliability
If conventional pumps are used, then the structure is established, but the wear and energy consumption are high
Solution Approach 1:
The pump operation parameters including pressure, flow rate, and timing are optimized to minimize wear on moving parts while reducing energy consumption. The adjustable nozzle system allows for efficient fluid delivery that reduces the workload on the pump, extending its service life.

AI summary
A fluid discharging system having a pump and a discharging spray head having at least one nozzle through which fluid to be discharged exits is provided. The pump has a stator and a rotor which is attached in a chamber of the stator and can be rotated in relation to the stator about a rotational axis and axially along the axis. The axial displacement of the rotor in a first axial direction is configured such that it brings about pump filling operation. A fluid is drawn via an inlet into the stator chamber, and the axial displacement in an opposite second axial direction is configured such that it brings about discharging operation. The fluid in the chamber is expelled out of an outlet of the pump. The outlet of the pump is arranged in the rotor, and the discharging spray head is fluidically connected to the outlet of the pump.
