Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical connection is used to couple the x-ray source and detector panel, then the system structure is stable and easy to operate, but the operating locations are restricted and the geometry of scannable objects is limited
Solution Approach 1:
The system divides the x-ray imaging system into two independent components: a handheld x-ray source and a separate detector panel. This segmentation allows each component to be positioned independently, enabling operation in diverse locations and geometries without requiring a fixed mechanical connection between source and detector.
2Object-affected harmful factors
If a sweeping pencil beam collimator is used to produce a focused x-ray beam, then the beam size is reduced and scattered radiation is minimized, but the operator must move the instrument to fully x-ray the object
Solution Approach 1:
The system employs a dynamic geometry configuration where the detector panel can be independently positioned at optimal distances from the object while the handheld source is moved freely by the operator. This dynamic arrangement allows the use of focused beam collimators while eliminating the need for precise instrument positioning, as the detector adapts to different scanning scenarios.
3Object-affected harmful factors
If shielding is added to reduce scattered x-ray energy, then operator safety is improved and allowable operating time is increased, but the device complexity and size increase
Solution Approach 1:
The system introduces an intermediary detector panel that is mechanically independent from the handheld source. This separation allows the source to be compact with minimal shielding while the detector panel, positioned separately, captures the x-ray signal. The intermediary wireless communication system transmits data between the separated components, enabling safety without adding bulk to the handheld device.
4Power
If a high energy x-ray source (120 keV or greater) is used, then the penetrating power is increased for security screening, but the radiation safety risks increase in congested areas
Solution Approach 1:
The system replaces the traditional mechanical coupling and fixed geometry system with a wireless communication-based data transmission system. This allows the handheld high-energy source to operate independently without requiring close proximity to the detector, reducing radiation exposure time and distance for operators in congested areas while maintaining the high penetrating power needed for security screening applications.
