Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing stimulation systems use conventional waveforms, then the system structure remains simple, but the therapeutic efficacy cannot be optimized
Solution Approach 1:
The stimulation waveform is segmented into two distinct frequency components: a low-frequency component (1-100 Hz) that induces paresthesia for pain masking, and a high-frequency component (1-10 kHz) that provides spread-spectrum stimulation for enhanced therapeutic effect. This segmentation allows each component to perform its specific therapeutic function while maintaining overall system reliability
Solution Approach 2:
The system employs parameter changes by varying the frequency characteristics of the stimulation waveform. The low-frequency component operates at 1-100 Hz to produce paresthesia, while the high-frequency component operates at 1-10 kHz with spread-spectrum characteristics. This parameter differentiation enables optimized therapeutic efficacy for chronic pain and incontinence conditions
2Adaptability or versatility
If a single-frequency stimulation waveform is used, then the device operation is simple, but the adaptability to different therapeutic conditions is limited
Solution Approach 1:
The dual-frequency waveform generation system provides universal applicability across different therapeutic conditions. The low-frequency component addresses paresthesia-inducing requirements for pain relief, while the high-frequency spread-spectrum component addresses conditions requiring broader neural stimulation. This multi-functionality enables a single device to treat multiple conditions including chronic pain and incontinence
Solution Approach 2:
The system incorporates dynamics by enabling independent adjustment of the low-frequency and high-frequency components. The relative amplitudes, frequencies, and duty cycles of each component can be dynamically modified based on therapeutic requirements, allowing the device to adapt to different patient conditions and treatment protocols
