Solution Overview
Problem
Existing X-ray inspecting apparatuses with numerous detection elements on the X-ray-incident side face high manufacturing costs due to increased assembly complexity and potential discontinuity issues, which can lead to reduced X-ray sensitivity.
Innovation Solution
The apparatus employs a configuration with multiple detection units aligned in a specific direction, where scintillators and detection main bodies are continuously aligned without gaps, using ceramic bases for support and overhanging elements to ensure continuity and simplify assembly, while maintaining low X-ray source output for broad energy band detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If numerous detection elements are disposed on the X-ray-incident side, then X-ray detection capability is improved, but manufacturing cost and assembly complexity increase
Solution Approach 1:
The detection part is divided into multiple detection units, each comprising a scintillator and detection main body. These segmented units are arranged in a specific configuration where scintillators are positioned on the X-ray-incident side while detection elements are placed on the opposite side, reducing assembly complexity while maintaining detection capability across a broad energy band.
2Measurement precision
If numerous detection elements are disposed on the X-ray-incident side, then X-ray detection capability is improved, but manufacturing cost increases
Solution Approach 1:
Instead of placing detection elements directly on the X-ray-incident side, the invention inverts the conventional arrangement by positioning scintillators on the X-ray-incident side and detection elements on the opposite side. This inversion allows for simpler manufacturing and assembly processes while still achieving broad energy band detection through the scintillator conversion process.
3Measurement precision
If detection elements are disposed on the X-ray-incident side, then direct X-ray detection is achieved, but discontinuity issues reduce sensitivity
Solution Approach 1:
The scintillators perform a preliminary conversion of X-rays to visible light before the detection elements process the signal. This preliminary action ensures continuous and consistent detection across all elements, as the scintillators uniformly convert incident X-rays regardless of minor positional variations, thereby maintaining detection sensitivity and consistency.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for effective detection of X-rays across a broad energy band while reducing manufacturing costs and maintaining sensitivity, ensuring continuous element and scintillator alignment for consistent performance.
Implementation Method 1
The scintillators emit visible light rays of a predetermined wavelength band by absorbing X-rays of an energy band higher than the predetermined energy band
Implementation Method 2
