Solution Overview
Problem
Existing laser-therapy devices are not optimized for efficient and economical treatment of acupuncture points, lacking advanced modulation techniques to effectively interact with the body's metabolism and nerve receptors, and do not provide precise targeting and power regulation.
Innovation Solution
A laser-therapy device with a control unit, laser emitting means, and modulation means that combine square-wave modulations at specific frequencies (100 Hz, 1-2 Hz, and 5-20 Hz) to create a time-modulated sequence for selective stimulation of acupuncture points, along with a point-targeting module for precise location and power regulation, ensuring effective energy delivery and diffusion along acupuncture meridians.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple square-wave modulations are combined to interact with different physiological mechanisms, then treatment efficacy is improved, but device complexity increases
Solution Approach 1:
The laser emission is segmented into multiple discrete square-wave modulations (first at 100 Hz for proteoglycan interaction, second at 1-2 Hz for opioid stimulation, third at 5-20 Hz for meridian diffusion), each targeting specific physiological mechanisms. This segmentation allows independent optimization of each modulation's parameters while maintaining overall treatment efficacy.
Solution Approach 2:
Multiple square-wave modulations are merged into a single composite modulation signal that drives the laser emitting means. The modulations are combined through logical operations (AND gates) to create a time-modulated sequence that delivers all three frequency components simultaneously, achieving synergistic physiological effects without requiring separate laser sources.
2Object-affected harmful factors
If precise power regulation is implemented to maintain physiological relevance, then safety is improved, but device complexity increases
Solution Approach 1:
The laser power delivery is converted from continuous to periodic pulsed action through square-wave modulations. The duty cycle of each modulation is precisely regulated to ensure the average power remains within safe physiological limits while allowing peak powers sufficient for effective tissue interaction. This periodic action inherently provides safety through temporal separation of high-power pulses.
Solution Approach 2:
The system regulates power by dynamically changing the duty cycle parameter of each square-wave modulation rather than adjusting peak power or frequency. This parameter change approach allows precise control of average power delivery while maintaining the physiological relevance of pulse timing and frequency characteristics, simplifying the control architecture compared to continuous power regulation methods.
3Reliability
If modulation frequencies are optimized for specific physiological interactions, then treatment effectiveness is improved, but ease of operation decreases
Solution Approach 1:
The system is designed with pre-optimized modulation frequencies (100 Hz, 1-2 Hz, 5-20 Hz) that correspond to known physiological resonance frequencies for proteoglycan metabolism, opioid synthesis, and meridian signal diffusion. The device automatically applies these scientifically-determined parameters without requiring the operator to perform complex parameter optimization, making the system self-sufficient in delivering effective treatment.
Solution Approach 2:
The system maintains fixed, physiologically-optimized frequency parameters while allowing flexible adjustment of the duty cycle parameter. This approach preserves the scientific validity of the frequency selections for specific physiological interactions while providing operational flexibility through duty cycle variation, balancing treatment effectiveness with ease of use.
