X-ray Generator Anode Parallel Movement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray generators with multiple generation zones face challenges in maintaining accurate positional alignment during parallel movement, leading to oscillation and tilting of the anode, which complicates the correct determination of the X-ray generation zone facing the cathode.
Innovation Solution
The X-ray generator employs a casing with driving and guiding means disposed uniformly relative to the center axis of a seal member, along with elastic-force-imparting means, to ensure precise parallel movement of the anode without lateral oscillation or tilting, allowing both X-ray generation zones to face the cathode at the same distance and angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single drive mechanism is used to move the anode parallel to the cathode, then the device complexity is reduced, but the anode oscillates laterally and tilts during movement, making it difficult to correctly determine the position of the X-ray generation zone
Solution Approach 1:
The single drive mechanism is divided into multiple drive mechanisms (first and second drive mechanisms) positioned at different locations. Each drive mechanism independently moves the anode, and by coordinating their actions, lateral oscillation and tilting are prevented while maintaining parallel movement accuracy.
Solution Approach 2:
Multiple drive mechanisms are combined to work together on the same anode. The first drive mechanism moves the anode in one direction while the second drive mechanism moves it in another direction, and their combined action achieves accurate parallel movement without oscillation or tilting.
2Device complexity
If the drive mechanism is disposed at a position separated from the center rotational axis of the anode, then the structure is simplified, but the anode tilts during parallel movement
Solution Approach 1:
Different regions of the anode are acted upon by different drive mechanisms positioned at specific locations. The first drive mechanism is disposed at a first position while the second drive mechanism is disposed at a second position, allowing localized control that prevents tilting while maintaining overall structural simplicity.
3Ease of operation
If negative pressure caused by air suction is applied to the anode at a position separated from the center rotational axis, then the anode can be moved, but the anode oscillates laterally and tilts during movement
Solution Approach 1:
The single air suction force is segmented into multiple air suction forces applied at different positions. The first air suction force is applied at a first position and the second air suction force is applied at a second position, allowing coordinated movement that prevents lateral oscillation and tilting while maintaining ease of operation.
