Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray apparatuses cannot dynamically scan objects spot by spot, limiting their effectiveness in safety inspection and medical treatment applications.
Innovation Solution
An integrated flying-spot X-ray apparatus is developed, comprising a ray generator, a revolving collimator device driven by a frameless torque motor, and a cooling system, all mounted on a compact frame, enabling dynamic spot-by-spot scanning by rotating the collimator device with an aperture outside the sector-shaped X-ray beam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional X-ray apparatus emits X-ray along a conical plane or sector plane, then the X-ray coverage area is large, but dynamic spot-by-spot scanning capability is lost
Solution Approach 1:
The patent segments the X-ray beam path by introducing a collimator with movable apertures that divides the conical/sector X-ray beam into selectable directional beams. This segmentation enables spot-by-spot scanning capability while maintaining the simplicity of the original X-ray tube structure, as the collimator acts as an independent modular component.
Solution Approach 2:
The patent introduces a collimator as an intermediary device between the X-ray tube and the inspection target. This collimator with its rotatable aperture structure mediates the X-ray beam direction, enabling dynamic scanning without requiring direct movement of the X-ray tube or complex positioning systems.
2Volume of moving object
If functional devices are integrated on a mounting frame, then the apparatus structure becomes compact, but heat dissipation from the ray generator becomes more challenging
Solution Approach 1:
The patent extracts the cooling function from the integrated mounting frame by adding a dedicated cooling device with separate cooling channels. This extraction allows the ray generator to be closely integrated with other components for compactness while maintaining effective heat dissipation through the independent cooling system.
Solution Approach 2:
The mounting frame serves multiple functions: it provides structural support for integrating the ray generator, collimator, and other components to achieve compactness, while simultaneously serving as a thermal management structure with integrated cooling channels that conduct heat away from the ray generator.
3Adaptability or versatility
If the collimator device is made rotatable to achieve scanning, then spot-by-spot scanning is enabled, but the device complexity and control difficulty increase
Solution Approach 1:
The patent implements dynamic scanning capability by making the collimator rotatable about the ray generator. This dynamic structure allows the aperture to be positioned at different angles to achieve spot-by-spot scanning, while the rotation mechanism is designed to be simple and controllable.
Solution Approach 2:
The collimator apertures are pre-positioned at specific angles around the ray generator, allowing for predetermined scanning patterns. This preliminary arrangement of aperture positions enables systematic scanning without requiring complex real-time calculation or control algorithms.
