Solution Overview
Problem
Low level light therapy (LLLT) is underutilized due to poorly understood biochemical mechanisms, leading to anecdotal and empirical results, and existing delivery systems fail to provide well-defined dose applications, making it difficult to prescribe effectively for specific medical indications, with wearable devices lacking feedback mechanisms and remote monitoring capabilities.
Innovation Solution
A wearable LLLT device with a control module featuring a microprocessor, light sources, power source, memory, and communication modules, capable of delivering personalized light therapy with sensors to monitor treatment effectiveness and adjust dosages, and incorporating validation mechanisms to ensure authorized use and appropriate dosage delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If LLLT is applied with basic delivery systems, then treatment can be provided, but the dosage cannot be precisely controlled and monitored
Solution Approach 1:
The patent implements feedback mechanisms through sensors that monitor treatment parameters (light dosage, temperature, patient response) and communicate this data back to the control module. This enables real-time adjustment of treatment parameters to achieve precise dosage control while maintaining manageable device complexity through automated closed-loop control.
Solution Approach 2:
The patent replaces manual mechanical dosage control with electronic and optical control systems. Microprocessors control light source intensity and duration, while optical sensors and communication modules enable automated monitoring and adjustment, substituting mechanical precision requirements with electronic control capabilities.
2Ease of operation
If wearable LLLT devices are used for patient comfort, then portability is improved, but feedback and monitoring capabilities are lost
Solution Approach 1:
The patent integrates multiple functions into the wearable device including light therapy delivery, sensor monitoring, wireless communication, and data processing. This multi-functionality enables the device to maintain portability and wearability while simultaneously capturing and transmitting treatment feedback information to external systems for monitoring and analysis.
Solution Approach 2:
The patent uses wireless communication modules and intermediate data transmission systems to bridge the wearable device and external monitoring systems. This intermediary approach allows the wearable device to remain simple and comfortable while still enabling comprehensive feedback and monitoring capabilities through remote data access.
3Ease of operation
If LLLT treatment parameters are standardized, then ease of prescription is improved, but adaptability to individual patient needs deteriorates
Solution Approach 1:
The patent implements dynamic treatment parameter adjustment based on real-time sensor data and patient-specific factors. The control module can modify light dosage, wavelength, and treatment duration during the therapy session based on monitored parameters, enabling the system to adapt to individual patient needs while maintaining a standardized interface for prescription and delivery.
Solution Approach 2:
The patent enables changes in treatment parameters (wavelength, power, pulse duration, treatment time) based on patient-specific conditions and real-time feedback. This allows the system to start with standardized protocols and dynamically adjust parameters to optimize treatment for each individual patient's response and requirements.
