Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle stops for inspection and persons get off the vehicle, then inspection safety is improved, but inspection efficiency deteriorates
Solution Approach 1:
The inspection system transitions from a static stopped-vehicle mode to a dynamic moving-vehicle mode. The vehicle carries the inspection apparatus and moves through the inspection area, allowing continuous motion during inspection. This dynamic approach eliminates the need to stop and disembark, simultaneously maintaining safety through automated operation and improving efficiency by eliminating idle time.
Solution Approach 2:
The inspection system operates autonomously without requiring manual intervention or passenger disembarkation. The automated inspection apparatus performs scanning and detection functions while the vehicle moves, making the system self-sufficient and eliminating the need for human operators to exit the vehicle during inspection.
2Productivity
If the vehicle moves during inspection, then inspection efficiency is improved, but driver safety from X-ray irradiation deteriorates
Solution Approach 1:
The driver is extracted from the inspection area by positioning the driver's seat or driver position outside the X-ray scanning zone. The inspection apparatus scans the vehicle cargo area while the driver remains in a safe position, separating the harmful X-ray exposure zone from the driver's location. This allows the vehicle to move during inspection without exposing the driver to radiation.
Solution Approach 2:
The vehicle structure itself acts as an intermediary barrier between the X-ray source and the driver. The vehicle body, cargo area, and structural components shield the driver from direct X-ray exposure while allowing the inspection apparatus to scan the cargo space. This intermediary protection enables safe operation during motion.
3Productivity
If the scanning speed is increased, then inspection efficiency is improved, but measurement precision deteriorates
Solution Approach 1:
The inspection system maintains continuous scanning action without interruption or pausing. The X-ray apparatus operates continuously as the vehicle moves, eliminating gaps in the inspection process. This continuous operation allows higher speeds while maintaining precision through uninterrupted data collection and real-time image processing.
Solution Approach 2:
The inspection system incorporates feedback mechanisms that monitor the inspection process in real-time and adjust parameters to maintain quality. Sensors and detectors provide continuous feedback on cargo detection, allowing the system to compensate for motion effects and maintain measurement accuracy even at increased speeds through adaptive control.

AI summary
The present disclosure provides a vehicle-carried quick inspection system (11). The vehicle-carried quick inspection system may comprise an X-ray source (12) and a detector (13), the X-ray source and the detector being arranged to form an inspection passage. The vehicle-carried quick inspection system further comprises a controller (18) configured to control the X-ray source so that X-ray irradiation dose is extremely low when the driver's cab of the inspected vehicle passes through an X-ray beam, and control the X-ray source so that the irradiation dose of the X-ray source becomes a working dose when the other subsequent portions of the inspected vehicle pass through the X-ray beam. With the vehicle-carried quick inspection system of the present disclosure, a mobile and fully automated security inspection system is obtained and quick inspection can be achieved, while protecting the driver from being damaged from X-ray irradiation. Compared to fixed inspection systems or mobile inspection systems in prior arts, the vehicle-carried quick inspection system of the present disclosure can provide more convenient and quicker inspection.
