Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pain therapy technologies, such as TENS and implanted electric stimulators, are ineffective for high-grade chronic pain and neuropathic pain resistant to conventional analgesics, with unsatisfactory reproducibility and patient compliance issues due to limited dynamic range and recruitment of nerve fibers.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional TENS or implanted electric stimulators are used, then the apparatus is simple and easy to operate, but the analgesic effect is unsatisfactory for high-grade chronic pain and neuropathic pain
Solution Approach 1:
The patent implements dynamic frequency and amplitude modulation of the electrical stimulus, allowing the signal parameters to vary over time according to pre-programmed sequences. This dynamic adjustment enables the system to adapt to different pain states and nerve fiber recruitment requirements, significantly improving analgesic effectiveness for resistant pain types while maintaining reasonable device complexity through automated control algorithms.
Solution Approach 2:
The system employs systematic changes in multiple signal parameters including frequency (5-100 Hz), amplitude, and duty cycle, with automatic scanning capabilities that adjust these parameters in predetermined sequences. This multi-parameter modulation approach allows the apparatus to target different nerve fiber types and pain pathways, resolving the contradiction between signal complexity and therapeutic effectiveness.
2Extent of automation
If automatic frequency and amplitude scanning is implemented, then the operation is automated, but the reproducibility and patient compliance remain unsatisfactory
Solution Approach 1:
The patent pre-programs specific frequency and amplitude sequences that have been optimized based on clinical research and Gate Control theory principles. These predetermined scanning patterns ensure consistent and reproducible nerve fiber recruitment across different patients and treatment sessions, while maintaining full automation of the signal delivery process. The pre-programmed sequences eliminate operator variability and ensure clinically validated parameter ranges are always used.
3Reliability
If high-frequency stimulation is used to block pain transmission, then the analgesic effect is stronger, but the patient compliance decreases due to tolerability issues
Solution Approach 1:
The system uses periodic modulation of the electrical stimulus with variable duty cycles, alternating between active stimulation phases and rest periods. This periodic action allows high-frequency bursts sufficient for pain blocking to be delivered intermittently, reducing cumulative sensory overload and patient discomfort while maintaining effective analgesia during active phases. The automated programming ensures optimal rest-stimulation ratios are maintained throughout treatment.
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
The solution achieves high reproducibility and patient compliance by generating effective 'non-pain' information strings that provide immediate and long-term analgesia, overcoming limitations of existing technologies in treating resistant pain types.
Implementation Method 1
Pain therapy by electrostimulation is practiced with apparatuses normally producing wave trains ranging from 5 to 100 Hz
Implementation Method 2
More reliable is the explanation of operation according to Gate Control theory. Accordingly, these electric stimulations are deemed to have an inhibiting function on painful stimulus transmission, by blocking electric-type nerve conduction.
