Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the diameter of the jet of HP-nozzles is reduced to reduce water consumption, then water consumption is reduced, but the cleaning result may be compromised
Solution Approach 1:
The invention divides a single large-diameter jet into multiple smaller-diameter jets by providing several nozzle elements (e.g., 2-5 nozzles) in the nozzle body. This segmentation allows the total water consumption to be reduced while maintaining effective cleaning coverage through multiple jet streams that collectively cover the same area as a single larger jet would have.
2Productivity
If multiple nozzle elements are arranged to increase planar performance, then productivity is improved, but device complexity increases
Solution Approach 1:
The invention combines multiple nozzle elements and their respective jet channels into a single integrated nozzle body. This merging approach allows multiple jets to be delivered from one compact component rather than requiring separate nozzle assemblies, thereby increasing planar cleaning performance while minimizing the increase in device complexity.
Solution Approach 2:
The nozzle body is designed as a universal component that can accommodate multiple nozzle elements with different orientations and angles. This multi-functional design allows a single nozzle body to perform multiple cleaning functions simultaneously, addressing different surface areas and angles with one integrated component rather than requiring multiple separate devices.
3Adaptability or versatility
If the nozzle body is made rotational to optimize jet alignment, then adaptability is improved, but device complexity increases
Solution Approach 1:
The invention introduces a rotational capability to the nozzle body, allowing it to be rotated around its longitudinal axis to different angular positions. This dynamic adjustment feature enables optimization of jet alignment with the paper machine direction and coverage area. The rotational mechanism is designed to be simple, allowing manual or automated rotation to predetermined positions without complex control systems.

AI summary
A nozzle arrangement (1) for a high-pressure cleaning or conditioning device of a paper machine having a nozzle body (2), with a first jet channel (3) for liquids impinged with high pressure passing therethrough, with at least one partially penetrating nozzle element (4) being arranged in the jet channel (3), which forms the liquid passing the jet channel (3) into a laminar jet (5). In order to provide a nozzle arrangement (1) increasing the efficiency of the spray tube with a good cleaning result and simultaneously reduced water consumption it is provided that at least one additional nozzle element (4) is located at the nozzle body, which is arranged in another jet channel (3) different from the first jet channel (3) or together with the first and/or another nozzle element (4) in a joint jet channel (3) and that the nozzle body (2) is arranged at the nozzle arrangement (1) rotational about its longitudinal axis without being off-set axially.
