Solution Overview

Problem

Existing methods for red light DNA phototherapy lack standardization in duration, intensity, and delivery mechanisms, leading to inadequate or excessive exposure, which can be harmful and ineffective in repairing DNA damage.

Innovation Solution

A DNA repair device with a housing containing a translucent platform, electromagnetic energy sources, a thermal sensor, heat exchanger, and control circuit that modulates light intensity and duration to provide safe and targeted red light therapy, using wavelengths between 620 nm and 640 nm, and adjustable intensity and duration between 0.18 mW/cm2 and 50 mW/cm2 for 5-60 minutes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If red light intensity is increased to enhance DNA repair effectiveness, then repair efficiency is improved, but tissue damage and carcinogenic side effects occur

Engineering Contradiction:

ImproveDNA repair efficiencyVSAvoidtissue damage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The device dynamically adjusts light intensity and exposure duration based on real-time temperature feedback from the thermal sensor. The control circuit modifies operational parameters to maintain optimal repair effectiveness while preventing tissue damage, transforming the static light delivery system into a dynamic, adaptive system that responds to tissue conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The thermal sensor provides continuous temperature feedback to the control circuit, which then adjusts the electromagnetic energy sources accordingly. This closed-loop feedback system ensures that light intensity remains within safe thresholds while maintaining sufficient repair effectiveness, preventing both under-treatment and over-treatment.

Inventive Principle:

Principle #23Feedback

2Duration of action of moving object

If red light exposure duration is prolonged to improve DNA repair, then repair effectiveness is enhanced, but excessive electromagnetic radiation causes further DNA damage

Engineering Contradiction:

Improvelight exposure durationVSAvoidDNA damage

Core Design Contradiction:

Duration of action of moving objectVSObject-generated harmful factors

Solution Approach 1:

The control circuit implements periodic or pulsed light delivery patterns rather than continuous exposure. By alternating between active light emission and pause periods, the system allows tissue recovery between exposures, preventing cumulative damage while maintaining repair effectiveness through repeated controlled doses.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system changes operational parameters (intensity and duration) based on real-time conditions monitored by the thermal sensor. The control circuit adjusts these parameters dynamically to optimize the balance between repair effectiveness and safety, preventing both insufficient and excessive exposure.

Inventive Principle:

Principle #35Parameter changes

3Object-affected harmful factors

If red light intensity is reduced to ensure safety, then tissue damage is prevented, but DNA repair effectiveness becomes inadequate

Engineering Contradiction:

Improvetissue safetyVSAvoidDNA repair effectiveness

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The system dynamically adjusts light intensity based on real-time temperature feedback rather than using a fixed low intensity. This allows the system to operate at higher effective intensities when safe and automatically reduce intensity when approaching safety thresholds, optimizing both safety and effectiveness.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The periodic action pattern ensures continuous therapeutic effect through repeated exposure cycles. By maintaining treatment over multiple controlled intervals rather than using a single prolonged exposure, the system accumulates repair effectiveness while preventing excessive damage through rest periods between exposures.

Inventive Principle:

Principle #20Continuity of useful action
