Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If nozzles are continuously arranged in a staggered manner to cover the whole width of metal plate strip, then descaling coverage is improved, but energy and water waste increases when processing narrow specification plates
Solution Approach 1:
The nozzle arrangement system is made dynamically adjustable through independent drive mechanisms that can shift nozzles along guide rails. This allows the nozzle configuration to adapt from a dense staggered arrangement for wide plates to a reduced arrangement for narrow plates, eliminating energy and water waste while maintaining full coverage capability when needed.
Solution Approach 2:
The system changes the spatial parameters of nozzle arrangement by adjusting the position and quantity of active nozzles based on plate width. The independent drive mechanisms enable continuous adjustment of nozzle positions along the width direction, transforming the fixed staggered arrangement into a variable configuration that matches the actual processing requirements.
2Area of stationary object
If nozzles are symmetrically arranged on both sides of the plate strip to ensure coverage, then descaling coverage is improved, but nozzle service life decreases due to mutual spray interference
Solution Approach 1:
The nozzle system uses independent drive mechanisms to dynamically adjust the positions of nozzles on both sides of the plate strip. This allows the system to maintain symmetric coverage for wide plates while reducing or eliminating mutual interference for narrow plates, thereby extending nozzle service life without compromising coverage area.
Solution Approach 2:
The spatial parameters of nozzle positions are continuously adjustable along the width direction. By changing the lateral position of nozzles based on plate width, the system eliminates direct face-to-face spray interference that occurs in fixed symmetric arrangements, reducing nozzle damage while maintaining adequate coverage.
3Area of stationary object
If the number of nozzles is increased to cover the widest width specification, then descaling coverage is improved, but device complexity increases
Solution Approach 1:
The nozzle system is divided into multiple independently controllable modules, each capable of being positioned and adjusted separately. This segmentation allows the system to cover wide areas when needed while simplifying the active configuration for narrower plates, reducing overall system complexity through modular independence.
Solution Approach 2:
Each nozzle module serves multiple functions: it can be positioned at different locations along the width direction, adjusted in its spray angle, and independently activated or deactivated. This multi-functionality reduces the need for numerous fixed nozzles, simplifying the overall device while maintaining comprehensive coverage capability.
4Ease of manufacture
If nozzles are fixed in a traditional straight arranging manner, then manufacturing simplicity is maintained, but adaptability to different width specifications decreases
Solution Approach 1:
The system transforms the fixed straight arrangement into a dynamic configuration through independent drive mechanisms that can shift nozzles along guide rails. This maintains the simplicity of the basic linear structure while adding the capability to adapt to different width specifications through controlled positional changes.
Solution Approach 2:
The system changes the positional parameters of nozzles along the width direction based on the required plate width. By adjusting the lateral position of nozzles while maintaining their linear arrangement, the system adapts to different specifications without requiring complex reconfiguration or redesign of the overall structure.

AI summary
A method for arranging jet cleaning nozzles comprising: arranging multiple rows of nozzles in a parallel and uniform manner along a lengthwise direction of a metal plate strip; arranging the nozzles in each row at an equal interval; arraying adjacent rows of nozzles in a staggered manner along the widthwise direction of the metal plate strip so as to form a nozzle matrix; wherein each nozzle is perpendicular to a moving direction of the metal plate strip, and the perpendicular distance of each nozzle to a surface of the metal plate strip is the same. Through the method for arranging jet cleaning nozzles, nozzles can be flexibly controlled based on the change of the geometric relationship between nozzles, in order to implement efficient and continuous descaling on the surfaces of a metal plate strip with different width specifications and different requirements on the descaling speed. In this way, waste of energy and water resources occurred when changing specifications is avoided, and the phenomenon that upper and lower nozzles spray to each other is also avoided, thereby achieving flexible and efficient control over the arrangement mode of jet cleaning nozzles for descaling.
