Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patch sensors for ultrasound imaging systems lack flexibility in adapting to different bandwidth and power consumption requirements, limiting their ability to transmit diverse medical data types without needing to be repositioned on a subject.
Innovation Solution
A patch sensor with a transducer array and dual processing pathways generates and transmits two types of medical data signals, switching between low-bandwidth and high-bandwidth communication modes based on available resources and connection types to optimize power and bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the patch sensor transmits high-bandwidth second signal carrying detailed ultrasound imaging data, then the quality and detail of medical data transmission is improved, but the power consumption and communication resource usage increases
Solution Approach 1:
The patch sensor dynamically switches between first communication mode (transmitting first signal with lower bandwidth) and second communication mode (transmitting second signal with higher bandwidth) based on available communication resources and power conditions, allowing adaptive adjustment of transmission quality and power consumption
2Adaptability or versatility
If the patch sensor transmits comprehensive medical data including both physiological and ultrasound imaging data, then the versatility and diagnostic value is improved, but the communication bandwidth requirement increases
Solution Approach 1:
The medical data is segmented into two distinct types: first type (physiological data) transmitted via first signal in first communication mode, and second type (ultrasound imaging data) transmitted via second signal in second communication mode, allowing selective transmission based on clinical needs
Solution Approach 2:
The patch sensor is designed with multi-functionality to perform both physiological monitoring and ultrasound imaging, transmitting different types of data through the same device depending on the communication mode activated, thereby providing versatile monitoring capabilities
3Loss of information
If the patch sensor operates in second communication mode transmitting large bandwidth data, then the information completeness is improved, but the loss of energy increases
Solution Approach 1:
The system dynamically adjusts the communication mode based on energy availability and clinical priorities, switching between first communication mode (lower energy consumption, less complete data) and second communication mode (higher energy consumption, more complete data) to optimize the trade-off between information completeness and energy loss
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient transmission of different medical data types, such as physiological and ultrasound imaging data, without repositioning the sensor, by adjusting bandwidth and power consumption according to available communication channels and power sources.
Implementation Method 1

Data Source
AI summary
A patch sensor adapted to process echo information to generate a first type of medical data and/or a second, different type of medical data using a respective processing pathway. A communications module of the patch sensor is adapted to be switchable between a first mode, in which only the first type of medical data is transmitted to a medical device, and a second mode, in which at least the second type of medical data is transmitted to the 5 medical device. The first type of medical data occupies a smaller bandwidth (during transmittal) than the second type of medical data.
