Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real array technology is used to achieve high imaging performance, then imaging performance is improved, but device volume increases
Solution Approach 1:
The patent replaces the mechanical real array system with an electronic synthetic aperture system. Instead of using multiple physical antenna elements arranged in a large array, the invention uses a single or small number of antenna elements combined with digital signal processing to synthesize a large aperture, thereby achieving high imaging performance while minimizing device volume.
Solution Approach 2:
The patent changes the operating parameters by using electromagnetic wave frequencies in the microwave or millimeter-wave band, which have longer wavelengths compared to optical frequencies. This allows the system to achieve diffraction-limited resolution with a smaller aperture size, resolving the contradiction between imaging performance and device volume.
2Measurement precision
If mechanical control is used to achieve high track positioning precision, then positioning precision is improved, but device volume increases
Solution Approach 1:
The patent replaces mechanical positioning systems (such as mechanical arms or optical tracking devices) with an electronic self-positioning system. The system uses electromagnetic signals and digital processing to determine and correct for positional deviations, achieving high track positioning precision without requiring bulky mechanical components.
3Volume of moving object
If synthetic aperture technology is used to reduce device volume, then device volume is reduced, but track positioning precision requirement increases
Solution Approach 1:
The patent replaces mechanical positioning requirements with electronic self-positioning capabilities. The system incorporates sensors and signal processing algorithms that automatically detect and compensate for positional deviations, eliminating the need for precise mechanical control while maintaining high imaging quality with a compact device.
