Solution Overview
Problem
Existing dispersion plates with multilayer constructions are complex, laborious, and costly to produce, and they lack reproducibility in spraying direction and conical mist formation, which is essential for applications like fuel combustion and aerosol spraying.
Innovation Solution
A dispersion plate with a common longitudinal axis for the inlet, passage, and outlet, where the opening wall is parallel to the axis and divergent from it, allowing for reproducible spraying direction and conical mist formation, made in a single piece using electroplating methods, facilitating easy production and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multilayer construction is used to achieve turbulence and improve atomization, then the dispersion plate can spray mist in a conical manner, but the structure becomes complex and production becomes laborious and costly
Solution Approach 1:
The patent merges multiple functional layers into a single integrated dispersion plate structure. The single plate incorporates the inlet, passage, outlet, and turbulence-generating features all in one piece, eliminating the need for separate layers while maintaining the atomization and conical spray functions.
Solution Approach 2:
The dispersion plate is segmented into distinct functional zones within a single structure: the inlet region, the passage with turbulence-generating elements, the outlet region, and the conical spray formation zone. This segmentation allows each function to be optimized independently while maintaining overall simplicity.
2Reliability
If a multilayer construction is used to improve atomization, then mist dispersion is enhanced, but production becomes laborious and costly due to critical positioning requirements
Solution Approach 1:
By combining all layers into a single dispersion plate manufactured as one piece, the patent eliminates the laborious and costly positioning process required for multilayer constructions. The single-piece manufacturing approach ensures consistent positioning of all features without requiring critical alignment between separate layers.
3Manufacturing precision
If the passage diameter is varied to control spray direction, then spraying direction reproducibility improves, but the structure becomes more complex
Solution Approach 1:
The dispersion plate incorporates local variations in passage diameter at specific locations to control spray direction. The passage has a first diameter section and a second diameter section with different dimensions, creating localized flow characteristics that ensure reproducible spraying direction without requiring complex overall structure.

AI summary
A dispersion plate for dispersing a fluid includes two surface sides, a peripheral side and at least one through-opening which extends between the two surface sides, the opening including an inlet on one surface side, a passage, and an outlet on the other surface side, and the inlet, the passage and the outlet being delimited by an opening wall of the dispersion plate. The inlet, the passage and the outlet have a common longitudinal axis, the part of the opening wall delimiting the passage being substantially parallel to the common longitudinal axis, and the part of the opening wall delimiting the outlet, from the passage to the surface side where the outlet is located, being divergent relative to the common longitudinal axis. A method for producing a dispersion plate by electroplating is also described.
