Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single array element and single channel are used, then the device complexity is low, but the measurement precision and dimensional information capability are insufficient
Solution Approach 1:
The ultrasonic probe is divided into multiple independent array elements (first array element, second array element, etc.) with corresponding independent channels. Each array element can be controlled separately by master processing modules and slave processing modules, allowing simultaneous multi-dimensional detection while maintaining manageable complexity through modular segmentation
Solution Approach 2:
The system transitions from single-dimensional detection to multi-dimensional detection by adding multiple array elements arranged in different spatial positions. The master processing module coordinates these elements to transmit ultrasonic waves in multiple directions simultaneously, enabling three-dimensional visualization and comprehensive viscoelasticity assessment
2Productivity
If multiple array elements and channels are added, then the productivity and detection efficiency improve, but the device complexity increases
Solution Approach 1:
Multiple processing modules (master processing modules and slave processing modules) are merged into a coordinated system where the master processing module generates synchronization signals that are distributed to slave processing modules. This merging enables synchronized control of multiple array elements, achieving high detection efficiency while managing system complexity through integrated control architecture
Solution Approach 2:
A synchronization signal transmission mechanism acts as an intermediary between the master processing module and slave processing modules. This intermediary ensures coordinated operation of multiple array elements by distributing synchronization signals, thereby improving detection efficiency without proportionally increasing control complexity
3Productivity
If ultrasonic waves are transmitted simultaneously by multiple array elements, then the detection speed and information acquisition rate increase, but the energy consumption increases
Solution Approach 1:
The system employs periodic transmission of ultrasonic waves through multiple array elements under synchronized control. The master processing module generates periodic synchronization signals that coordinate the timing of ultrasonic wave transmission across different array elements, enabling high information acquisition rates while managing energy consumption through controlled periodic operation rather than continuous operation

AI summary
A method for detecting biological signs based on an ultrasonic detection system includes: sending, by a second processing module, a detection instruction to a master processing module in a first processing module; generating, by the master processing module, a first synchronization signal based on the detection instruction, and sending the first synchronization signal to a synchronous distribution module, so as to make the synchronous distribution module send the first synchronization signal to the master processing module and a slave processing module in the first processing module, and enable the slave processing module and the master processing module to control array elements to which they are respectively connected to transmit an ultrasonic wave simultaneously based on the first synchronization signal and collect an echo signal; and processing, by the second processing module, the echo signal collected by each array element to obtain information about the biological signs of an organism.
