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

VSEngineering 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

Engineering Contradiction:
Improveimage qualityVSAvoiddetector durability
Core Design Contradiction:
Measurement precisionVSReliability

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

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

Engineering Contradiction:
ImproveX-ray intensityVSAvoidoptical system complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Inventive Principle:
Principle #1Segmentation
