Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The durability of X-ray generating apparatuses is compromised due to degradation of insulating members when irradiated with radiation, leading to reduced insulating performance.
Innovation Solution
An X-ray generating apparatus with an insulating fluid-filled outer case, featuring a third window with a higher linear expansion coefficient than the insulating member, which fits into an opening between the first and second windows, allowing for flowable insulating fluid and enhanced voltage withstand capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the insulating member is directly exposed to X-ray irradiation, then the structure is simplified, but the insulating member degrades and durability is reduced
Solution Approach 1:
The insulating fluid serves as a protective cushion between the X-ray irradiation source and the insulating member. By placing the fluid in advance, it absorbs and attenuates the radiation before it reaches the insulating member, thereby cushioning the member from degradation and extending its service life.
2Ease of manufacture
If a fixed insulating structure is used, then manufacturing is simplified, but maintenance and replacement of insulating components become difficult
Solution Approach 1:
The insulating system is segmented into two distinct components: a fixed insulating member that provides structural support and a movable insulating fluid that can be independently replenished or replaced. This segmentation allows the fluid to be maintained separately from the structural component, simplifying maintenance procedures.
Solution Approach 2:
The insulating system transitions from a static solid insulating member to a dynamic system where the insulating fluid can flow and be replenished. The fluid's ability to move and be replaced dynamically enables easy maintenance without requiring disassembly of the entire insulating structure.
