Static CT Detection Device with Opening Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CT detection devices require objects to be moved onto a conveying belt for detection, which is inefficient and can lead to contamination and radiation exposure, especially when detecting sensitive materials like meat.
Innovation Solution
A static CT detection device with a shielding body and an opening portion that allows objects to be conveyed directly through a detection channel without contact, using a ray source and detector arranged outside the channel to prevent radiation leakage and contamination, and incorporating a shielding cover and labyrinth-like structure for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conveying belt is used to transport objects through the detection channel, then objects can be detected, but the device complexity increases and contamination risk increases
Solution Approach 1:
The patent removes the conveying belt system entirely from the detection device. Instead of having objects conveyed through a enclosed channel with belts, the invention uses an open detection area where objects can be directly detected while moving through the space, eliminating the need for mechanical conveying components and their associated complexity
Solution Approach 2:
The detection space is divided into a detection area surrounded by shielding walls and a separate opening area. This segmentation allows objects to pass through the opening without contacting the shielding structure or conveying mechanisms, while still enabling detection within the protected detection area
2Productivity
If a conveying belt is used to transport objects, then detection can be performed, but manual operations are required and efficiency decreases
Solution Approach 1:
The detection device allows objects to be detected automatically as they pass through the opening area. The system does not require manual placement onto conveying belts or intervention to move objects through the detection process, enabling continuous automated detection of moving objects
3Reliability
If objects are moved onto a conveying belt, then detection can occur, but contamination risk increases for sensitive materials
Solution Approach 1:
The invention extracts objects from the enclosed detection channel environment and allows them to pass through an open detection area. This eliminates contact between objects and potential contamination sources such as conveying belts, shielding surfaces, and mechanical components within the detection path
Solution Approach 2:
The opening area serves as an intermediary space between the external environment and the protected detection area. Objects pass through this intermediate zone without contacting the shielding structure or detection channel walls, preventing contamination while enabling detection
4Object-affected harmful factors
If a closed detection channel is used to prevent radiation leakage, then radiation safety is improved, but the device becomes more complex and requires conveying mechanisms
Solution Approach 1:
Instead of enclosing the entire detection space, shielding walls are strategically positioned only where radiation containment is necessary. The opening area remains unshielded to allow object passage, while localized shielding prevents radiation leakage in critical directions, reducing overall structural complexity
