Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional on-board relocatable container/vehicle inspection systems face challenges in inspecting small vehicles with lower chassis, as they require complex and costly structures to lower scanning equipment for effective scanning without opening the vehicle.
Innovation Solution
A ramp-platform device that can be disassembled and folded for easy transportation, allowing the vehicle to be raised to a suitable height for scanning by assembling and spreading the ramp-platform device, enabling inspection of the chassis and wheels of small vehicles with a lower chassis without the need for complex structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the scanning vehicle uses a conventional fixed structure, then the scanning height is maintained at over 400 mm, but the chassis and wheels of small vehicles with lower chassis cannot be inspected
Solution Approach 1:
The inspection system is divided into a fixed scanning vehicle and a separate adjustable ramp-platform device. The ramp-platform can be independently assembled and disassembled, allowing the inspection height to be adjusted for different vehicle types without modifying the main scanning vehicle structure.
Solution Approach 2:
The ramp-platform device introduces dynamic adjustability to the inspection system. By allowing the platform height to be changed through assembly and disassembly of ramp parts, the system can adapt to different inspection requirements (standard vehicles vs. low-chassis vehicles) without permanent structural modifications.
2Adaptability or versatility
If the detector and radiation source are lowered to inspect small vehicles, then the scanning range is widened and scanning target is lowered, but the structure becomes complex and cost increases
Solution Approach 1:
The height adjustment function is extracted from the main scanning vehicle and placed in a separate ramp-platform device. This allows the scanning vehicle to maintain its simple, fixed structure while the ramp-platform provides the necessary height variability for different inspection scenarios.
Solution Approach 2:
The inspection system is segmented into a fixed scanning vehicle and a separate adjustable ramp-platform. The ramp-platform handles the height adjustment function independently, avoiding the need to modify the detector or radiation source positioning mechanisms.
3Ease of manufacture
If a fixed high scanning height is used, then the scanning vehicle structure is simple, but small vehicles with lower chassis cannot be effectively scanned
Solution Approach 1:
The system transitions from a static, fixed-height scanning arrangement to a dynamic, adjustable-height arrangement through the ramp-platform device. The platform can be assembled to raise small vehicles to the scanning height or disassembled for transport, providing versatility without complicating the main vehicle structure.
Solution Approach 2:
The inspection capability is segmented from the scanning vehicle itself and placed in a separate ramp-platform device. This allows the scanning vehicle to remain simple and fixed in structure while the ramp-platform provides the necessary height adjustment for different vehicle types.
4Adaptability or versatility
If a complex adjustable structure is used to inspect small vehicles, then the scanning range is improved, but the cost and structural complexity increase
Solution Approach 1:
The adjustable height function is segmented into a separate ramp-platform device that can be independently manufactured and assembled. This modular approach allows for simpler manufacturing of individual components compared to an integrated complex structure, potentially reducing overall system cost.
Solution Approach 2:
The system uses a dynamic assembly/disassembly mechanism for the ramp-platform that provides adjustability without requiring complex permanent structural modifications. This dynamic approach uses simpler, more cost-effective components compared to fixed complex structures.
