X-ray emitter housing axial threaded ring seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing x-ray emitter housings face issues with uneven contact pressure distribution on sealing elements due to radial screw connections, leading to reduced tightness under extreme temperature changes and prolonged operation, which affects the vacuum integrity.
Innovation Solution
The use of an axially acting threaded ring to connect the housing parts, ensuring even contact pressure distribution on a sealing element, such as an O-ring, eliminates the need for multiple radial screws and provides a reliable, constant seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If radial screw connections are used to connect housing parts, then alignment and structural stability are provided, but contact pressure is applied only at particular points and is not transmitted homogeneously onto the sealing element
Solution Approach 1:
The connection structure is segmented into multiple radial screw connections that work together to achieve both alignment stability and improved pressure distribution on the sealing element
Solution Approach 2:
The screw connections are strategically positioned at specific locations around the housing to optimize both structural alignment and pressure distribution characteristics at different regions of the sealing element
2Stability of the object's composition
If radial screw connections are used to connect housing parts, then alignment is fixed, but contact pressure acting on particular points may reduce over time, impairing tightness
Solution Approach 1:
The screw connections are pre-adjusted and pre-tensioned during assembly to establish optimal contact pressure distribution before operation begins, compensating for potential pressure reduction during extended use
Solution Approach 2:
The design incorporates mechanisms that maintain contact pressure over time through the interaction of multiple radial screws working together, ensuring sustained tightness despite operational changes
3Stability of the object's composition
If multiple radial screws are used to connect housing parts, then alignment is provided, but the number of components and assembly complexity increases
Solution Approach 1:
The connection system is divided into multiple radial screw positions that can be assembled in a systematic pattern, reducing overall complexity through standardized repetition
Solution Approach 2:
The radial screw connections serve multiple functions simultaneously: providing alignment, distributing pressure, and maintaining structural integrity, thereby reducing the need for additional specialized components
