Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low Level Laser Therapy (LLLT) results in inconsistent and slow therapeutic effects due to a lack of understanding of its mechanisms, leading to variable outcomes depending on dosage, exposure rhythm, and tissue distance from the laser source, and is limited to inducing only photochemical and photothermal effects.
Innovation Solution
A device employing a pulsed laser source with a peak intensity fluence (PIF) of 0.1 to 1.0 J/cm³, capable of inducing photomechanical, photothermal, and photochemical effects through controlled peak intensity, pulse duration, and duty cycle, allowing for deeper tissue penetration and regenerative therapy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Low Level Laser Therapy (LLLT) is used with power between few mW and 1,000 mW, then the therapy can be applied safely to tissue, but the therapeutic results are obtained slowly and are inconsistent
Solution Approach 1:
The patent changes the key parameter of laser power from low levels (few mW to 1,000 mW) to high intensity levels (above 1,000 mW), specifically using pulsed laser beams with peak intensities of 1,000-50,000 mW. This parameter change enables both fast and consistent therapeutic results while maintaining safety through controlled pulse duration and duty cycle
Solution Approach 2:
The patent employs pulsed laser emission rather than continuous low-level emission. The periodic pulsed action with specific duty cycles (1-100%) allows high peak power delivery while providing rest periods, achieving both rapid therapeutic effects and tissue safety, thereby improving consistency and speed of results
2Productivity
If high intensity pulsed laser beam is used with peak intensity fluence (PIF) of 0.1 to 1.0 J/cm³, then photomechanical, photothermal, and photochemical effects are induced for faster tissue regeneration, but the risk of tissue damage increases
Solution Approach 1:
The pulsed laser delivery system delivers high intensity energy in periodic bursts rather than continuous exposure. By controlling pulse duration (microseconds to seconds) and duty cycle (1-100%), the system induces rapid photomechanical, photothermal, and photochemical effects during pulse peaks while allowing thermal dissipation during off-periods, thus achieving fast regeneration without tissue damage
Solution Approach 2:
The patent maintains continuous therapeutic action through optimized pulse sequences and duty cycles. The overlapping of pulse effects and continuous energy delivery at controlled intervals ensures sustained regenerative stimulation while preventing thermal accumulation that could cause tissue damage, bridging the gap between high intensity and safety
