Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a linear array probe with single-frequency scanning method is used, then the device complexity is reduced, but the imaging resolution is limited by probe frequency and detection depth
Solution Approach 1:
The probe is segmented into multiple independent receiving components arranged in a two-dimensional array, where each component can be independently controlled. This segmentation allows the system to achieve high imaging resolution through precise spatial sampling while managing complexity through modular architecture, as each segment operates independently with dedicated control circuits.
Solution Approach 2:
The patent implements dynamic control of the receiving components through electronic switching and signal processing. The system dynamically adjusts which receiving components are active, their gain settings, and signal routing based on the scanning requirements. This dynamic operation enables the probe to adapt to different imaging depths and resolutions without physical reconfiguration, resolving the contradiction between resolution and complexity.
2Measurement precision
If multiple receiving components are distributed in a two-dimensional array with integrated control circuits, then the imaging resolution is improved, but the device complexity and power consumption increase
Solution Approach 1:
The system employs periodic scanning sequences where receiving components are activated in systematic patterns across the two-dimensional array. Rather than all components operating simultaneously, the scanning method periodically activates specific components based on the imaging depth and resolution requirements. This periodic activation significantly reduces average power consumption while maintaining high imaging resolution through the systematic coverage of the array elements.
Solution Approach 2:
The patent changes operational parameters such as the activation pattern, gain settings, and scanning frequency of receiving components based on imaging requirements. By dynamically adjusting these parameters, the system optimizes the balance between imaging quality and power consumption, allowing high resolution when needed while reducing power usage during normal operation.
3Measurement precision
If a two-dimensional array of receiving components with row and column signal lines is implemented, then the imaging resolution is enhanced, but the circuit design complexity increases
Solution Approach 1:
The control circuits integrated with each receiving component are designed as multi-functional units that can perform multiple operations including signal amplification, analog-to-digital conversion, and electronic switching. This universality reduces the need for separate dedicated circuits for each function, thereby managing overall circuit complexity while supporting the enhanced imaging resolution provided by the two-dimensional array architecture.
Solution Approach 2:
The patent merges multiple circuit functions into integrated control circuits that are combined with each receiving component. By combining amplification, switching, and signal processing functions into single integrated units, the system reduces the total number of discrete components and interconnections required, thereby managing circuit design complexity despite the sophisticated two-dimensional array configuration.
