Extruded Vacuum Chamber with Segmented Door for Leak-Tight Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum systems with chamber extruded profiles require laborious milling for opening, leading to inefficiencies in leak-tightness and production costs.
Innovation Solution
A vacuum system with a chamber extruded profile that is fully closed transversely to the central longitudinal axis, featuring a reversibly opening and closing end-face door, eliminating the need for milling, and incorporating hinge projections, latch holder projections, and cooling ribs for enhanced leak-tightness and cost-effective production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an opening is milled into the chamber extruded profile for loading and unloading, then the vacuum chamber can be accessed, but the production becomes laborious and leak-tightness is compromised
Solution Approach 1:
The chamber extruded profile is segmented into a closed main body and a separate door component. The door is detachably connected to the chamber profile via a door receiving structure, allowing the opening function to be achieved without milling into the main chamber body. This segmentation maintains the integrity and leak-tightness of the chamber while providing easy access for loading and unloading.
2Ease of operation
If the chamber extruded profile is opened by milling, then access is provided, but leak-tightness is reduced and assembly costs increase
Solution Approach 1:
The chamber is segmented into a closed extruded profile and a separate door that attaches to a door receiving structure. This segmentation preserves the continuous, uninterrupted structure of the main chamber body, ensuring leak-tightness while providing access through the detachable door mechanism.
Solution Approach 2:
The door receiving structure is pre-formed as an integral part of the chamber extruded profile during the extrusion process. This preliminary formation of the receiving structure eliminates the need for subsequent milling operations and ensures that the opening mechanism is already integrated and leak-tight before final assembly.
3Ease of operation
If a door is added to the chamber extruded profile, then access is improved, but device complexity increases
Solution Approach 1:
The door system is segmented into separate functional components: the door itself, the door receiving structure in the chamber profile, and the hinge connection. This segmentation allows each component to be optimized independently and assembled in a straightforward manner, reducing overall complexity compared to integrating a door directly into the extruded profile.
Solution Approach 2:
Instead of integrating the door opening directly into the chamber profile through milling, the solution inverts the approach by making the door a separate component that attaches to the profile. The chamber profile provides the receiving structure, and the door provides the opening function, reversing the traditional integration approach and simplifying the overall design.

AI summary
A vacuum system, such as the form of a plasma system, includes a vacuum chamber. The side walls of the vacuum chamber are configured in the form of a completely closed chamber extruded profile. A first end face of the chamber extruded profile is closed off with a plate. A second end face of the chamber extruded profile, which lies opposite the first end face, has a reversibly openable and closable door. The door is fastened by at least one hinge pivotably to the chamber extruded profile. The side walls, which are fully closed transversely to the longitudinal axis of the chamber extruded profile, enable a simple and cost-effective production of the vacuum chamber. The vacuum chamber may be accommodated at least partially in a housing, which may likewise be configured at least partially in the form of an extruded profile.
