Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If optical 3D scanning systems are used to capture external features, then surface imaging capability is improved, but internal structure visibility deteriorates
Solution Approach 1:
The patent replaces optical imaging systems with electromagnetic (microwave) imaging systems. The mechanical/optical approach using cameras and lasers is substituted with electromagnetic wave transmission and reception through the object, enabling penetration into internal structures while maintaining imaging capability.
Solution Approach 2:
The electromagnetic imaging system performs multiple functions: it captures both external surface features and internal structural information simultaneously, and can also determine material properties. This multi-functionality resolves the contradiction by making a single system capable of both surface imaging and internal visualization.
2Measurement precision
If laser distance measurement devices are used to obtain 3D contours, then external shape measurement is improved, but internal part detection deteriorates
Solution Approach 1:
The patent replaces mechanical laser ranging systems with electromagnetic wave-based imaging. Instead of measuring external contours through laser time-of-flight, the system transmits electromagnetic waves through the object to detect internal structures, thereby enabling internal part detection while maintaining measurement precision through sophisticated signal processing.
Solution Approach 2:
The patent introduces electromagnetic waves as an intermediary that can penetrate the object rather than being reflected by the surface. This intermediary enables the detection system to interact with internal structures directly, bypassing the limitation of surface-only measurement inherent in laser-based systems.
3Reliability
If RF array systems are used for planar imaging, then security screening capability is improved, but full 3D imaging capability deteriorates
Solution Approach 1:
The patent transitions from planar 2D RF imaging to full 3D electromagnetic imaging by adding spatial dimensionality to the antenna array configuration and image reconstruction process. This enables comprehensive three-dimensional visualization of objects while maintaining the reliable detection capabilities of RF systems.
4Manufacturing precision
If conventional 3D scanners are used to model objects, then external surface modeling is improved, but internal structure modeling deteriorates
Solution Approach 1:
The patent replaces conventional optical/mechanical 3D scanning with electromagnetic imaging to create comprehensive models that include internal structures. The substitution enables non-destructive penetration imaging that captures both external geometry and internal features, providing complete mechanical models for manufacturing applications.
Solution Approach 2:
The patent performs preliminary electromagnetic characterization of the object's internal structure before physical manufacturing or intervention. This preliminary imaging action provides complete structural information that guides subsequent manufacturing processes, eliminating the need for physical dissection or destructive testing.
