Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact-based detection methods (stethoscope or ultrasonic device) are used, then detection can be performed, but infection risk increases and requires specialized operators
Solution Approach 1:
The patent replaces mechanical contact-based detection (stethoscope, ultrasonic probe) with an electromagnetic field-based radar detection system. The radar device emits electromagnetic waves that reflect off the abdomen, allowing contactless detection of intestinal peristalsis through signal processing of the reflected waves, thereby eliminating infection risk while maintaining detection capability
Solution Approach 2:
The patent introduces electromagnetic waves as an intermediary medium between the detector and the patient's abdomen. Instead of direct physical contact, the radar device uses emitted and reflected electromagnetic waves to obtain information about intestinal peristalsis, serving as a non-contact mediator that eliminates infection risk
2Measurement precision
If ultrasonic wave instrument is used, then intestinal peristalsis can be detected, but the instrument is very expensive and cannot provide long-term monitoring
Solution Approach 1:
The patent employs a radar-based detection system that uses readily available radar components and signal processing techniques, avoiding the need for expensive specialized ultrasonic equipment. The system processes reflected electromagnetic wave signals to extract intestinal peristalsis information, providing a cost-effective solution suitable for long-term monitoring
Solution Approach 2:
The radar detection system is designed to be multi-functional, capable of detecting various abdominal movements including intestinal peristalsis. The same radar apparatus and signal processing methodology can be applied to different detection scenarios, reducing overall system cost and enabling long-term monitoring applications
3Loss of information
If stethoscopic or ultrasonic detection is used, then peristalsis information can be obtained, but quantification diagnosis is not achieved
Solution Approach 1:
The patent implements a feedback mechanism where the reflected electromagnetic wave signals are continuously processed and analyzed. The signal processing unit extracts peristalsis information from the reflected waves and provides quantitative feedback about intestinal activity, enabling objective measurement and diagnosis rather than subjective assessment
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 real-time, non-contact, and long-term monitoring of intestinal peristalsis, reducing costs and infection risks, and providing accurate quantification of intestinal activity without the need for specialized operators.
Implementation Method 1
the antenna receives the pulse signal to emit a pulse electromagnetic wave to the organism. When the pulse electromagnetic wave is reflected, the antenna receives the reflected pulse electromagnetic wave
Implementation Method 2
the mixer can combine the pulse signal and the response pulse signal
Data Source
AI summary
An intestinal peristalsis detecting device comprises a radio frequency (RF) signal generator, an antenna, and a mixer. After the RF signal generator sends a pulse signal, the antenna receives the pulse signal and emits a pulse electromagnetic wave to an organism. Thereafter, the antenna receives a response pulse electromagnetic wave reflected from the organism to generate a response pulse signal. The mixer couples with the RF signal generator and the antenna to mix the pulse signal and the response pulse signal.
