Solution Overview
Problem
Existing oil mist separators face challenges in efficiently attaching metal-plate elements to cylindrical components without complex positioning processes, which can lead to insecure attachments and potential distortions during operation.
Innovation Solution
A structural unit featuring a metal-plate element with a segmented through-neck and overmolded plastic, where the cylindrical component is positioned through the neck, allowing for simplified manufacturing and secure attachment without requiring precise alignment in the spraying tool, and providing radial and axial support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex positioning process is used to attach the metal-plate element to the cylindrical component, then the attachment security is improved, but the manufacturing complexity increases
Solution Approach 1:
The through-neck is divided into multiple circumferentially spaced segments that are bent out of the metal plate element's plane. Each segment creates a discrete positioning feature that guides the cylindrical component into correct alignment, eliminating the need for complex positioning tools while ensuring secure attachment.
Solution Approach 2:
The segmented through-neck acts as an intermediary structure between the metal plate element and the cylindrical component. It provides mechanical guidance and positioning during assembly, allowing the components to self-align without requiring complex external positioning tools or procedures.
2Manufacturing precision
If precise alignment is required in the spraying tool, then the attachment precision is improved, but the manufacturing difficulty increases
Solution Approach 1:
The segmented through-neck structure is pre-formed in the metal plate element during manufacturing. The segments are bent out of the plane to create built-in positioning features that automatically guide the cylindrical component into correct alignment during assembly, eliminating the need for precise manual alignment or complex positioning tools.
Solution Approach 2:
The segmented through-neck enables the components to self-align during assembly. The geometry of the segments and the cylindrical component creates automatic positioning through mechanical interference, allowing the assembly process to be simpler and more tolerant of manufacturing variations without requiring high-precision alignment procedures.

AI summary
A structural unit includes a cylindrical component and a metal-plate element having a through-neck, and the cylindrical component extends though the through-neck and is attached to the cylindrical component. The through-neck substantially determines a position of the metal-plate element relative to the cylindrical component with respect to a radial direction of the cylindrical component. Also an oil mist separator including the structural unit.
