Traverser Shield Integration for X-ray Inspection Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing X-ray inspection apparatuses with multiple shield shutters complicate the structure, increase costs, and reduce inspection speed due to their size and complexity, while also allowing radioactive ray leakage during the feeding process.
Innovation Solution
The apparatus is designed with three compartments: a feed-in preparation chamber, an imaging chamber, and a feed-out preparation chamber, where a traverser with shields moves the inspection object in a direction different from its receipt and discharge, preventing radioactive ray leakage by maintaining a closed space and eliminating the need for additional shutters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple shield shutters are used to prevent radioactive ray leakage during object feeding, then radiation safety is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines the radiation shielding function with the object transport function by integrating shields into the traverser structure. The traverser carries both the inspection object and the shields simultaneously, merging two functions into one component system. This eliminates the need for separate shield shutters while maintaining radiation safety during feeding operations.
Solution Approach 2:
The traverser is designed as a multi-functional component that simultaneously performs object transport and radiation shielding. By making the traverser universal for both purposes, the patent reduces the total number of components needed and simplifies the overall system structure while ensuring radiation protection during the feeding process.
2Reliability
If multiple shield shutters are used to prevent radioactive ray leakage, then radiation safety is improved, but inspection speed decreases
Solution Approach 1:
By merging the shielding function into the traverser, the patent eliminates the time required for separate shutter operations. The shields move with the traverser during object feeding, eliminating delays associated with opening and closing independent shutters, thus maintaining high inspection speed while ensuring radiation safety.
Solution Approach 2:
The integrated shield-traverser system allows continuous operation during object feeding. Since the shields are part of the moving traverser assembly, they automatically follow the feeding motion without requiring separate activation cycles, maintaining continuous inspection workflow and high productivity.
3Reliability
If dual lane structure is combined with multiple shield shutters, then radiation safety is improved, but apparatus size increases
Solution Approach 1:
The patent merges the shielding function into the traverser structure in the dual lane system, eliminating the need for additional fixed shield shutters. This integration approach maintains radiation safety while avoiding the space requirements of separate shutter mechanisms, thus keeping the apparatus size compact.
Solution Approach 2:
The patent uses dynamic, movable shields integrated into the traverser rather than static fixed shutters. This allows the shielding to be present only when needed during object feeding, and eliminates the need for large fixed shutter structures, reducing the overall apparatus volume while maintaining radiation protection.

Function Achieved in This Case
This design shortens inspection time and prevents radioactive ray leakage, reducing the apparatus's complexity and cost by allowing simultaneous feeding and discharging of inspection objects during X-ray imaging without external exposure.
Implementation Method 1
a shield that moves together with the mount, and prevents radioactive rays that enter through one of the first opening and the second opening and propagate in the moving direction of the traverser from reaching the other one of the first opening and the second opening

AI summary
An inspection apparatus includes a feed-in preparation chamber, an imaging chamber, and a feed-out preparation chamber. Each preparation chamber includes a feed-in unit that receives an inspection object through a first opening, a traverser that translates the received object to a second opening in a direction different from the receiving direction of the object, and a feed-out unit that moves the object in a direction different from a moving direction of the traverser and discharges the object through the second opening. The imaging chamber includes an imaging unit that images the object fed from the feed-in preparation chamber. The traverser includes a mount for the object, and a shield that moves together with the mount and prevents radioactive rays entering one of the first and second openings and propagating in the moving direction of the traverser from reaching the other opening.
