Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an active NLJD system with orientable block and multiple sensors is used, then detection reliability and accuracy are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple detection functions (NLJD electronic component detection, optical confirmation imaging, and neutralization targeting) into a single integrable orientable block assembly. This merging allows the system to achieve high detection reliability through multi-sensor correlation while managing complexity through unified mechanical integration and coordinated control of all sensors within one modular unit.
2Reliability
If the detection range is extended to several tens of meters, then safety of the carrier is improved, but detection precision may deteriorate
Solution Approach 1:
The patent introduces an optical confirmation camera as an intermediary verification tool between the NLJD electronic detection and final target confirmation. This intermediary allows the system to maintain extended detection range for safety while compensating for potential precision loss at distance through optical imaging confirmation, enabling reliable identification of detected electronic components as actual IED threats.
3Area of stationary object
If an orientable block with scanning capability is used, then coverage area is improved, but operation complexity increases
Solution Approach 1:
The orientable block is designed as a universal platform that performs multiple functions: NLJD electronic component detection, optical imaging confirmation, and neutralization targeting. All these functions are integrated within the same mechanical structure and controlled through unified orientation control, allowing the system to cover large areas while simplifying operation through multi-functional integration rather than separate systems.
4Ease of operation
If manual adjustment of display scale is provided, then ease of operation is improved, but time consumption increases
Solution Approach 1:
The system provides self-service through automated functions that reduce manual intervention. The orientable block automatically scans and positions targets, the optical camera automatically captures and displays images of detected components, and the system correlates detection data with visual confirmation without requiring manual adjustment of display scales or manual analysis, thereby reducing both operational complexity and time consumption.

AI summary
The system has an orientable block (6) in which transmission and reception antennas (3, 4) of detecting units (2) are mounted. The detecting units detect improvised explosive devices, and are directed in a manner so as to illuminate same zones of a space. A detection confirmation camera (7) is directed toward the zones illuminated by the antennas so as to form an image of the zones. A control unit (8) controls orientation of the orientable block, and causes displacement of the block so as to generate scan of a part of the space by the detection units. An independent claim is also included for a mobile vehicle.
