Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple periodic signal is used to drive the antenna, then the device complexity is reduced, but the treatment efficacy for neurodegenerative diseases is insufficient
Solution Approach 1:
The patent applies periodic action by organizing the electromagnetic signal into a hierarchical structure of base pulses grouped into packets, which are further organized into trains. This periodic modulation at multiple levels creates a complex frequency spectrum that resonates with neural tissues, thereby improving treatment efficacy while maintaining a systematic approach to signal generation
Solution Approach 2:
The patent implements dynamics by varying the timing parameters (packet duration, train duration, intervals) of the electromagnetic signal structure. This dynamic adjustment allows the system to adapt the frequency spectrum to match different resonance frequencies of affected neural tissues, enhancing therapeutic effectiveness without requiring complex hardware
2Device complexity
If a single frequency electromagnetic signal is applied, then the device complexity is minimized, but the resonance effects on different neural tissues are insufficient
Solution Approach 1:
The patent segments the electromagnetic signal into distinct hierarchical components: base pulses, packets containing multiple base pulses, and trains containing multiple packets. This segmentation creates a rich frequency spectrum from a relatively simple generating mechanism, enabling resonance with multiple neural tissue types simultaneously
Solution Approach 2:
The patent utilizes parameter changes by systematically varying the duration and spacing of base pulses, packets, and trains. These parameter variations generate a broad frequency spectrum that can resonate with different neural tissues having different characteristic frequencies, thereby improving adaptability without complex hardware

AI summary
A system for therapeutic treatments with electromagnetic waves is described. The system comprises an antenna and an apparatus configured to generate a supply current for the antenna in order to generate the electromagnetic waves. The apparatus comprises a digital processing circuit configured to generate a first PWM signal, a switching stage configured to generate an amplified PWM signal, an analog low-pass or band-pass filter configured to generate the supply current by filtering the amplified PWM signal, and a current sensor configured to provide a digital sample indicative of the amplitude of the supply current.Specifically, the digital processing circuit generates a sequence of first digital values of a periodic base pulse. Moreover, the digital processing circuit generates a second PWM signal having a packet switch-on period and a packet switch-off period, generates a third PWM signal having a train switch-on period and a train switch-off period, and generates an enable signal as a function of the second PWM signal and the third PWM signal. The digital processing circuit generates then a second digital value, wherein the second digital value is set to the first digital value when the enable signal has a first logic level and to zero when the enable signal has a second logic level.In particular, the digital processing circuit generates the first PWM signal as a function of a third digital value indicative of the duty cycle of the first PWM signal, and varies the third digital value via a discrete proportional-integral regulation configured to regulate the difference between the second digital value and the digital sample to zero.
