Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray inspection apparatuses face challenges in attenuating vibration effectively, leading to inaccurate measurement results due to the shift mechanism being between the frame and anti-vibration mounting, which compromises the attenuation of external vibrations.
Innovation Solution
An X-ray apparatus design that integrates the shift mechanism and anti-vibration mechanism as one unit, allowing the frame to be shifted and maintained while attenuating vibrations, featuring a guide rail, shift members, and anti-vibration units positioned below the frame to reduce external vibration influence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a flat panel detector is used in an X-ray device, then image quality and detection sensitivity are improved, but the detector is fragile and susceptible to damage from impact or pressure
Solution Approach 1:
The housing structure serves multiple functions: it protects the flat panel detector from physical damage, provides mounting positions for various components (collimator, position-sensitive detector, light sources), and enables different operational modes (transmission, reflection, phase-contrast imaging) through configurable component arrangements
Solution Approach 2:
The patent positions the flat panel detector at the focal point of the parabolic mirror and structures the housing to absorb and distribute mechanical stresses before they can reach the detector, preventing damage from external impacts or pressure during operation
2Illumination intensity
If a parabolic mirror is used to focus synchrotron radiation, then X-ray intensity and image resolution are improved, but the device complexity and alignment requirements increase
Solution Approach 1:
The patent combines the parabolic mirror, flat panel detector, collimator, and position-sensitive detector into an integrated housing assembly with pre-established geometric relationships, reducing the complexity of field assembly and alignment while maintaining the optical focusing benefits
Solution Approach 2:
The patent utilizes the vertical dimension by positioning components at different heights within the housing, with the parabolic mirror below the flat panel detector and the light source above, creating a three-dimensional optical path that simplifies alignment compared to planar arrangements
3Adaptability or versatility
If multiple detectors are used to capture different types of imaging data, then diagnostic information and measurement capability are improved, but the device complexity and data processing requirements increase
Solution Approach 1:
The housing structure is designed to accommodate multiple detector types (flat panel detector for transmission imaging, position-sensitive detector for phase-contrast imaging) along with collimators and light sources, enabling a single device to perform multiple imaging functions through configurable component arrangements
Solution Approach 2:
The patent divides the imaging system into functionally independent modules (transmission imaging path with flat panel detector, phase-contrast imaging path with position-sensitive detector and collimator) that can be independently configured and operated, simplifying the management of complexity through modular design

AI summary
An X-ray apparatus includes: an X-ray source that radiates X-rays upon an object to be measured; a frame upon which the X-ray source is mounted; an anti-vibration mechanism that attenuates vibration applied to the frame; and a shift mechanism that shifts the frame and the anti-vibration mechanism integrally together.
