Vehicle Inspection Conveyor Overlapping Powered Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In X-ray inspection systems for small vehicles, the division of the conveyor into two sections creates an unpowered section, causing vehicles to stall when passing through, which affects inspection quality and complexity in propeller handover due to varying vehicle sizes and structures.
Innovation Solution
A vehicle inspection system conveyor with a first and second conveying device, featuring powered and unpowered sections arranged side by side, where the unpowered section is positioned within the range of powered sections, ensuring continuous driving force and simplifying the handover process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the conveyor is divided into two sections (front and rear) to avoid impact on imaging quality, then detectors can be easily placed on both sides and bottom, but an unpowered section exists at the junction causing vehicles to stall and affecting inspection process and image quality
Solution Approach 1:
The patent merges the powered sections of the first and second conveying devices to eliminate the unpowered gap. The first powered section and second powered section are positioned to overlap or abut, ensuring continuous power transmission through the scanning area, thus preventing vehicle stalling while maintaining detector placement capability.
Solution Approach 2:
The patent positions the powered sections in advance to cover the entire scanning area including the junction zone. By pre-configuring the powered sections to extend into the previously unpowered junction area, the system ensures continuous driving force is available before vehicles reach the transition zone, preventing stalls.
2Reliability
If propellers are provided on both sections for smooth handover, then conveying can be maintained, but control process becomes complicated and handover is unstable due to diversified vehicle sizes and structures
Solution Approach 1:
The patent ensures continuous powered sections overlap or abut to eliminate the unpowered gap entirely. This eliminates the need for propeller handover control, as the powered sections provide continuous driving force throughout the scanning area, simplifying control while maintaining reliable conveyance.
Solution Approach 2:
The patent segments the conveying system into multiple powered sections (first powered section and second powered section) that are independently controllable but positioned to provide continuous coverage. This segmentation allows each section to handle different vehicle types independently while maintaining overall continuity, reducing the complexity of coordinated handover.
3Device complexity
If the conveyor is divided into two sections with unpowered junction, then frame setting and turning are simplified, but vehicles slip and stall when passing through the unpowered section
Solution Approach 1:
The patent merges the powered sections to eliminate the unpowered junction zone. By extending the powered sections to cover the entire scanning area including the junction, the system maintains simple frame setting and turning while ensuring continuous driving force prevents vehicle slipping and stalling.

AI summary
A conveying device for a vehicle inspection system, and a vehicle inspection system. The conveying device is used for conveying a vehicle to be inspected from front to rear so that the vehicle to be inspected passes through a scanning area of a vehicle inspection system; and the conveying device comprises a first conveying device (10) and a second conveying device (20) arranged side by side in the left to right direction, wherein the first conveying device (10) comprises, within a conveying path of the vehicle to be inspected, at least one first powered section that provides a driving force to the vehicle to be inspected and at least one first non-powered section that does not provide a driving force to the vehicle to be inspected, and the second conveying device (20) comprises, within the conveying path of the vehicle to be inspected, at least one second powered section that provides a driving force to the vehicle to be inspected, wherein the first non-powered section is located within the range of at least one second powered section in the front to rear direction.
