Vehicle-Mounted CT Layout for Lower Height and Easier Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted security inspection systems face challenges with inconvenient maintenance due to the vertical or horizontal arrangement of item inspection machines, which can increase vehicle height and occupy excessive space when using high-end products like slip ring CTs.
Innovation Solution
A vehicle-mounted security inspection system with a CT security inspection device installed on a subframe, featuring a sunken structure and a transverse arrangement, which includes a rear frame with lower portions and a slip ring positioned lower than the main frame, allowing for compact design and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a high-end product such as slip ring CT is used, then the security inspection capability is improved, but the overall height of the vehicle-mounted security inspection apparatus increases, occupying a large space
Solution Approach 1:
The patent transitions from vertical arrangement to transverse arrangement of the CT security inspection device. The device is installed on the subframe extending in the transverse direction of the vehicle, with the slip ring positioned such that its height is lower than the main frame height, thereby reducing the vehicle's overall height while maintaining inspection capability
Solution Approach 2:
The CT security inspection device is nested within the vehicle's subframe structure. The device is installed on the subframe's rear portion, utilizing the existing vehicle structure to accommodate the inspection device without significantly increasing the vehicle's external dimensions
2Volume of moving object
If the CT security inspection device is installed on the subframe in transverse direction, then the vehicle height is reduced, but the maintenance convenience may be affected
Solution Approach 1:
The vehicle-mounted security inspection system is divided into independent modules: the CT security inspection device, the subframe, and the main frame. The CT device can be independently installed and maintained on the subframe, facilitating easier maintenance access compared to integrated vertical arrangements
