Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual measurement using laser theodolite is used for alignment, then the alignment can be performed with simple equipment, but the alignment accuracy and objectivity deteriorate due to human visual sense and instrument placement errors
Solution Approach 1:
The patent replaces the manual mechanical measurement system (laser theodolite) with an automated optical detection system. The accelerator target spot, collimator central line, and detector central line are automatically aligned using a detection device that measures their positions and calculates alignment deviations, eliminating human visual estimation and manual instrument placement errors while maintaining equipment simplicity.
2Productivity
If detector arm mount is used in movable inspection systems, then the system can be quickly deployed to new sites, but the alignment time increases due to mechanical adjustment requirements
Solution Approach 1:
The patent implements self-alignment functionality where the detection device automatically measures the positions of the accelerator target spot, collimator central line, and detector central line, and the system automatically calculates and guides the alignment adjustments. This eliminates the need for manual mechanical adjustments by operators, enabling quick deployment while maintaining accurate alignment through automated measurement and calculation.
3Device complexity
If manual alignment adjustment is performed, then the equipment can be aligned without automated systems, but the alignment objectivity and reliability deteriorate due to human error
Solution Approach 1:
The patent implements a feedback-based alignment system where the detection device continuously measures the positions of the accelerator target spot, collimator central line, and detector central line. The system calculates alignment deviations and provides feedback guidance for adjustments, repeating the measurement and calculation process until alignment meets predetermined standards. This automated feedback loop ensures objective and reliable alignment while keeping the system relatively simple.

AI summary
The present disclosure discloses an alignment system and an alignment method for a container or vehicle inspection system, and an inspection system. The inspection system comprises comprising an ray source, a collimator, a detector arm and a detector module mounted on a detector arm, the ray source, the collimator and the detector module are arranged to form an inspection passage, a ray beam emitted from the ray source passes through collimator and irradiates onto an inspected object, and an attenuated ray beam is collected by the detector module so as to complete inspection. The alignment system comprises a measuring module arranged to receive the ray beam emitted from the collimator and to measure the ray beam so as to determine positions and orientations of the ray source and the collimator. With the alignment method, alignment between a center point of the ray source, a central line of a detector tip and a central line of the collimator may be more accurately measured.
