Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic imaging methods for three-dimensional seismic models are limited and unable to achieve real-time imaging, particularly in complex geological structures, due to high requirements for probe directivity and consistency, and slow measurement speeds with low signal-to-noise ratios.
Innovation Solution
A real-time imaging system comprising an ultrasonic sensor network with a network of emitting and receiving probes, a hardware subsystem including a main control unit, acquisition unit, and industrial computer, and a software subsystem that uses pre-stack migration imaging algorithms to process wave train data and generate three-dimensional imaging maps without moving the probes, enabling panoramic imaging of complex geological structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two-dimensional array probes with phased array technology are used, then imaging directionality and consistency are improved, but scanning angle is limited and imaging region is restricted
Solution Approach 1:
The patent divides the imaging system into multiple independent ultrasonic probes arranged in a specific geometric configuration. Each probe independently transmits and receives ultrasonic signals, allowing the system to cover a wider imaging region while maintaining measurement precision through individual probe optimization.
Solution Approach 2:
The patent employs a nested probe structure where multiple ultrasonic probes are integrated within a compact positioning device. This nested arrangement allows the probes to maintain precise relative positions (improving consistency) while the entire assembly can be positioned to cover different regions (expanding imaging area).
2Device complexity
If mechanical scanning imaging with a single ultrasound probe is used, then device complexity is reduced, but measurement speed is slow and signal-to-noise ratio is low
Solution Approach 1:
The patent merges multiple ultrasonic probes into a single integrated system with synchronized control. By combining the transmitting and receiving functions of multiple probes and coordinating their operations through a unified control mechanism, the system achieves high measurement speed (improving productivity) while maintaining manageable complexity through integrated design.
Solution Approach 2:
The patent implements continuous ultrasonic signal transmission and reception across multiple probes simultaneously, eliminating the sequential scanning required by single-probe systems. This continuous parallel operation significantly increases measurement speed while the synchronized control system keeps device complexity at acceptable levels.
