Engineering Contradiction Analysis
1Object-affected harmful factors
If TENS devices utilize electronic stimulation to mask pain, then pain relief is achieved, but the body's natural healing process is not actively assisted
Solution Approach 1:
The device incorporates detector circuitry that continuously monitors physiological signals (such as muscle response or skin conductance) and feeds this information back to the processor. The processor adjusts stimulation parameters in real-time based on the detected body response, creating a closed-loop system that adapts to the user's healing needs rather than using fixed masking patterns
Solution Approach 2:
The device dynamically changes stimulation parameters including pulse width, amplitude, frequency, and packet configuration based on detected physiological states. This allows the stimulation to evolve from initial pain masking to active healing promotion as the body responds, with parameters being adjusted to match the healing stage and tissue recovery needs
2Device complexity
If stimulation signals use fixed packet configurations, then device complexity is reduced, but adaptability to different body responses is limited
Solution Approach 1:
The device transitions from static, pre-programmed stimulation packets to dynamic packets whose configuration changes in real-time based on detector circuitry feedback. The processor modifies packet parameters such as number of pulses per packet, inter-packet intervals, and pulse amplitudes dynamically, allowing the system to adapt to varying physiological conditions during treatment
Solution Approach 2:
The stimulation signal is divided into discrete packets of pulses, where each packet can be independently configured and adjusted. This segmentation allows the device to apply different stimulation patterns to different physiological conditions by modifying individual packet parameters while maintaining overall signal structure, balancing complexity with adaptability
