Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treatments for anxiety, insomnia, depression, and pain, such as TENS, provide temporary relief and require constant use due to lack of residual effect, leading to tolerance and limitations in long-term management.
Innovation Solution
A microcurrent electrical therapy (MET) system using a microcomputer-controlled device with a modified square, bipolar waveform delivered through electrodes or ear clip electrodes, providing long-lasting cumulative relief with adjustable current and timing for pain and cranial electrotherapy stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TENS devices are used for pain relief, then temporary relief is achieved, but residual effect is lacking and tolerance develops requiring constant use
Solution Approach 1:
The patent changes the electrical parameters from conventional TENS frequencies and amplitudes to microcurrent levels (microampere range) with specific waveform patterns (1000 Hz carrier frequency modulated at 0.5-10 Hz). This parameter transformation enables long-lasting cumulative relief by operating at a fundamentally different electrical scale that produces sustained physiological effects rather than temporary stimulation.
Solution Approach 2:
The patent employs periodic modulation of the microcurrent at low frequencies (0.5-10 Hz) while maintaining a high carrier frequency (1000 Hz). This periodic action pattern creates cumulative therapeutic effects over time, allowing the treatment to build up physiological changes that result in long-lasting relief without requiring constant device application.
2Reliability
If conventional electrical therapy is used, then pain relief is achieved, but side effects and physical limitations occur
Solution Approach 1:
The patent transforms the electrical parameters to microcurrent levels that are extremely low compared to conventional TENS therapy. This parameter change fundamentally alters the physiological interaction, producing therapeutic effects through subtle biochemical mechanisms rather than strong neural stimulation, thereby eliminating side effects while maintaining effectiveness.
3Duration of action of moving object
If microcurrent therapy is applied, then long-lasting cumulative relief is achieved, but device complexity increases
Solution Approach 1:
The patent uses periodic modulation techniques that simplify the device architecture by employing standard waveform generation circuits. The modulated microcurrent pattern (1000 Hz carrier modulated at 0.5-10 Hz) can be generated using conventional electronic components and timing circuits, avoiding the need for complex control systems while achieving long-lasting therapeutic effects.

AI summary
A device for controlling anxiety, insomnia, depression and pain utilizing a microcurrent and cranial electrotherapy stimulation. The device could also be utilized to treat other types of stress-related disorders. A relatively low level current having a particular frequency is produced by the device in two channels wherein the current for both of the channels can be different. Electrodes are placed at various points of the patient's body to relieve pain. When utilized to control anxiety, insomnia and depression, a single channel is produced which is applied to the patient's ear lobes by two ear clips.
