Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If single-element probes or multi-element array probes are placed on both sides of a pipeline for ultrasonic detection, then the detection can be performed, but the contact area between the probes and the slurry is limited and signal energy becomes inconsistent at different positions
Solution Approach 1:
The probe is divided into multiple array elements arranged in specific geometric patterns (linear, circular, or annular arrays). Each element can independently transmit or receive ultrasonic signals, allowing the system to segment the detection process and combine results from multiple elements to achieve consistent signal energy and improved measurement precision across different pipeline positions.
Solution Approach 2:
The invention transitions from traditional single-point probe contact to multi-dimensional array configurations. By arranging probe elements in two-dimensional or three-dimensional geometric patterns around the pipeline, the system achieves comprehensive coverage and consistent signal energy distribution across the entire detection area, resolving the position-dependent energy inconsistency problem.
2Area of stationary object
If probes are positioned at non-central locations in the pipeline, then more coverage area is achieved, but most energy is reflected at other angles resulting in inconsistent transmitted signal energy
Solution Approach 1:
The invention employs asymmetric probe configurations adapted to the specific detection needs and pipeline geometry. By optimizing the asymmetric arrangement of array elements and their individual beamforming parameters, the system achieves both extensive coverage area and consistent signal energy transmission, overcoming the limitations of symmetric central positioning.
Solution Approach 2:
Different array elements are configured with localized optimization for their specific positions and functions. Each element or subgroup of elements can be independently optimized for transmission or reception, allowing the system to achieve consistent signal energy across the entire coverage area while maintaining high measurement precision at each local detection point.
3Area of stationary object
If edge area probes are used for detection, then broader coverage is achieved, but reflected signals are directed in other directions resulting in inability to receive effective echo signals
Solution Approach 1:
The probe array is segmented into multiple elements that can independently control transmission and reception timing. By segmenting the detection process and using beamforming techniques across multiple elements, the system can receive effective echo signals from edge areas while maintaining broad coverage, as each element contributes to the overall signal reconstruction.
Solution Approach 2:
The system incorporates feedback mechanisms where received signals from all array elements are processed and combined to reconstruct the complete echo information. This feedback processing allows the system to recover effective echo signals even from edge detection positions where direct reception would be insufficient, thereby preserving information while maintaining broad coverage.
