Solution Overview
Problem
Current radiography diagnosis systems for hands are bulky, difficult to move, and require significant space due to separate X-ray source, irradiation zone, and image receiving device configurations.
Innovation Solution
Integration of a transmission-type X-ray source module, image receiving assembly, and shielding structure within a single casing, along with a shutter assembly for controlled irradiation and reduced source-image distance, enabling miniaturization and easy mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate X-ray source device, irradiation zone, and image receiving device are used, then reliable radiological diagnosis can be achieved, but the system becomes bulky and difficult to move
Solution Approach 1:
The patent combines the X-ray source device, irradiation zone, and image receiving device into a single integrated radiography diagnosis device. The X-ray source module and image receiving module are disposed within the same housing, with the irradiation zone positioned between them, creating a unified portable system that maintains diagnostic reliability while improving mobility.
2Reliability
If separate X-ray source device, irradiation zone, and image receiving device are used, then reliable radiological diagnosis can be achieved, but the system occupies significant space
Solution Approach 1:
The patent merges multiple functional components into a compact integrated device. The housing contains the X-ray source module, image receiving module, and irradiation zone in a space-efficient arrangement, significantly reducing the area occupied compared to separate equipment while preserving full diagnostic functionality.
3Area of moving object
If transmission-type X-ray source module with greater light-emitting angle range is used, then sufficiently large irradiation area can be achieved with reduced irradiation distance, but the source-image distance becomes shorter requiring precise positioning
Solution Approach 1:
The patent incorporates an adjustable positioning mechanism that allows dynamic adjustment of the object's position within the irradiation zone. This enables precise positioning to compensate for the shorter source-image distance while maintaining the advantage of a larger irradiation area through the transmission-type X-ray source's greater light-emitting angle range.

Implementation Method 1
The transmission-type X-ray source module is disposed in the casing and adapted to provide an X-ray toward the object to be detected in the shielded space
Implementation Method 2
the image receiving assembly receives the X-ray passing through the object to be detected at the same time
Implementation Method 3
The first shielding structure is disposed in the casing and forms a shielded space

AI summary
A radiography diagnosis device includes a casing having an opening, a first shielding structure, a dose measuring unit, a transmission-type X-ray source module, and an image receiving assembly. The first shielding structure is disposed in the casing and forms a shielded space located between the transmission-type X-ray source module and the image receiving assembly and corresponding to the opening. An object to be detected is adapted to enter the shielded space through the opening. The transmission-type X-ray source module is disposed in the casing and adapted to provide an X-ray toward the object to be detected in the shielded space. The image receiving assembly is disposed in the casing. During image capturing, the X-ray generated by the transmission-type X-ray source module is received by the dose measuring unit, and the image receiving assembly receives the X-ray passing through the object to be detected at the same time.
