X-Ray Tube Insulating Structure for Stable High-Magnification Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray generation apparatuses face instability and reduced enlargement ratio when the distance between the object and the X-ray generation unit is increased, due to discharge issues between the bending portion of the storage container and the cathode, which are not adequately addressed by existing solutions.
Innovation Solution
An X-ray generation apparatus design where the cathode is positioned between the anode and the bending portion of the storage container in the tube axis direction, with an insulating member blocking the path between the conductive line and the convex portion of the connecting portion, and an insulating liquid filling the internal space to suppress discharge, while maintaining a longer projecting portion for improved enlargement ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the length of the projecting portion of the storage container is increased to improve enlargement ratio, then the enlargement ratio is improved, but discharge readily occurs between the bending portion and the cathode
Solution Approach 1:
An insulating member is introduced as an intermediary component between the bending portion of the storage container and the cathode of the X-ray generation tube. This insulating member prevents direct electrical discharge while allowing the projecting portion to maintain its extended length for improved enlargement ratio. The insulating member acts as a mediator that blocks the harmful electrical discharge path without interfering with the geometric configuration needed for imaging.
2Reliability
If the distance between the bending portion and the cathode is increased to reduce discharge, then discharge is reduced, but the apparatus size increases
Solution Approach 1:
Instead of increasing the distance between the bending portion and cathode along the tube axis direction (one dimension), the insulating member is positioned to block the discharge path in a different spatial arrangement. This allows maintaining a compact apparatus size while still preventing discharge by utilizing spatial positioning in multiple dimensions rather than simply increasing linear distance.
3Reliability
If the cathode is arranged between the anode and the bending portion to reduce discharge, then discharge is reduced, but the operational stability becomes unstable when the distance between the bending portion and cathode is increased
Solution Approach 1:
The insulating member serves as a stable intermediary that maintains consistent electrical isolation between the bending portion and cathode regardless of their relative positions. This ensures operational stability by providing a reliable barrier against discharge, allowing the cathode to be positioned between the anode and bending portion without compromising system stability.
