Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional invasive blood analysis methods are used, then measurement accuracy is maintained, but real-time monitoring capability is lost and patient comfort deteriorates
Solution Approach 1:
The patent replaces mechanical/invasive blood sampling methods with radio frequency electromagnetic field-based detection. The system uses RF signals to interact with blood analytes noninvasively, eliminating the need for physical blood draws while enabling continuous real-time monitoring without compromising measurement capability
Solution Approach 2:
The patent introduces radio frequency signals as an intermediary medium to detect blood analyte levels. Instead of directly sampling blood, the system uses RF waves that interact with the blood tissue, allowing indirect measurement of glucose and other analytes through their effect on RF signal properties
2Measurement precision
If traditional invasive blood analysis methods are used, then measurement capability is maintained, but patient comfort and safety during surgery deteriorate
Solution Approach 1:
The patent replaces invasive mechanical blood sampling with noninvasive radio frequency detection, eliminating needles and physical penetration of skin during surgical procedures, thereby removing associated pain, infection risks, and patient discomfort while maintaining analyte measurement capability
Solution Approach 2:
The system enables continuous automated monitoring of blood analytes without requiring repeated manual interventions. The wearable device continuously measures analyte levels autonomously, eliminating the need for multiple invasive blood draws during surgery and reducing overall patient exposure to harmful factors
3Object-affected harmful factors
If real-time noninvasive monitoring is implemented, then patient comfort and safety are improved, but measurement precision and reliability may deteriorate
Solution Approach 1:
The system incorporates machine learning algorithms that continuously learn from and adapt to individual patient physiological patterns. The algorithms analyze RF signal variations in real-time, compensating for environmental interference and motion artifacts, thereby maintaining high measurement precision despite the noninvasive approach
Solution Approach 2:
The patent utilizes changes in radio frequency signal parameters (frequency, amplitude, phase) caused by interactions with blood analytes. By monitoring multiple RF parameter variations simultaneously and analyzing their relationships, the system extracts accurate analyte concentration data from noninvasive measurements
4Loss of information
If continuous real-time monitoring is implemented, then clinical decision-making capability is improved, but device complexity and processing requirements increase
Solution Approach 1:
The system divides the complex monitoring task into separate functional modules: RF signal acquisition, preprocessing filters, machine learning inference engine, and communication interfaces. This modular segmentation allows each component to be optimized independently and simplifies the overall system architecture despite the complexity of real-time analysis

Data Source
AI summary
A system which includes an apparatus for generating radio frequency scanning data which includes a transmitter for transmitting radio waves below the skin surface of a person and a two-dimensional array of receive antennas for receiving the radio waves, including a reflected portion of the transmitted radio waves that is reflected from a blood vessel of the person. The wave signal is compared to known standard waveforms, and similar waveforms are input into a machine learning algorithm to determine one or more health parameters of the person. The system then notifies the person and/or health professionals of the person's health status. The health parameters can be used to trigger other software and hardware modules such as another measurement device, a medication scheduler or alert, medical recommendations, guidance software, a virtual assistant, or any other hardware and/or software which may help the patient or health professionals.
