Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional industrial X-ray generators are bulky and heavy due to the use of high-pressure gas containers and large X-ray shielding members made of lead, which complicates their downsizing and lightweight design.
Innovation Solution
The design positions the X-ray tube and high-voltage generating section adjacently, using a molded member with insulating resin and a small amount of heavy metal oxide for shielding, and incorporates a booster circuit with piezoelectric transformers to reduce weight and volume, along with a controller and power supply driver arrangement for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-pressure gas containers are used for insulation, then insulation performance is improved, but device weight and volume increase
Solution Approach 1:
The patent replaces the mechanical high-pressure gas container insulation system with an electrical insulation system using molded members made of insulating resin. This substitution eliminates the need for heavy pressure vessels while achieving the required insulation performance through material properties and structural design.
Solution Approach 2:
The patent employs composite materials consisting of insulating resin combined with small amounts of heavy metal oxide for X-ray shielding. This composite approach provides both electrical insulation and radiation shielding functions in a single lightweight structure, replacing the need for separate heavy metal containers.
2Object-affected harmful factors
If large X-ray shielding members made of lead are used, then X-ray shielding performance is improved, but device weight increases
Solution Approach 1:
The patent uses composite materials where insulating resin is combined with small amounts of heavy metal oxide particles. This composite provides adequate X-ray shielding performance through the heavy metal oxide component while the resin matrix maintains structural integrity, achieving lightweight shielding without requiring large amounts of lead.
Solution Approach 2:
The patent applies X-ray shielding material locally only where radiation protection is necessary, rather than using large solid lead blocks. The heavy metal oxide is dispersed within the insulating resin at specific locations to provide targeted shielding while minimizing overall material usage and weight.
3Reliability
If X-ray tube and high-voltage generating section are arranged at unrelated positions, then insulation is improved, but device volume increases
Solution Approach 1:
The patent merges the X-ray tube and high-voltage generating section into a compact integrated unit. The molded member simultaneously provides electrical insulation between high-voltage components and X-ray shielding, eliminating the need for separate large-distance arrangements while maintaining insulation performance through material properties.
Solution Approach 2:
The use of composite insulating resin with heavy metal oxide allows the molded member to perform multiple functions (electrical insulation and X-ray shielding) in close proximity, enabling the X-ray tube and high-voltage section to be arranged adjacently without compromising insulation or requiring excessive volume.
4Ease of manufacture
If conventional molded member insulation is used, then manufacturing simplicity is improved, but X-ray shielding capability is insufficient
Solution Approach 1:
The patent enhances conventional molded member insulation by incorporating heavy metal oxide particles into the insulating resin matrix. This composite material maintains the ease of molding and manufacturing while adding X-ray shielding capability that pure insulating resin lacks, achieving both manufacturing simplicity and radiation protection.

AI summary
An X-ray generator includes a booster circuit formed by sequentially connecting a plurality of boosting steps extending from a low-voltage terminal to a high-voltage terminal of its own.The booster circuit is arranged in a lateral region of the X-ray tube so as to make the low-voltage terminal of its own correspond to the anode of the X-ray tube and the high-voltage terminal of its own correspond to the cathode of the X-ray tube. A lead wire extending from the cathode to the outside of the X-ray tube is connected to the high-voltage terminal of the booster circuit. A molded member containing insulating resin is formed to shield at least a cathode side end part of the X-ray tube, the lead wire outwardly extending from the cathode side end part and a high-voltage terminal side end part of the booster circuit.
