Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high energy laser radiation is used to reduce fat cells, then fat reduction effectiveness is improved, but risk of tissue damage and safety hazards increases
Solution Approach 1:
The patent divides the optical treatment system into multiple independent optical emitters (LEDs) arranged in arrays, each emitting at different wavelengths. This segmentation allows the energy to be distributed across multiple sources rather than concentrated in a single high-power laser, reducing the risk of localized tissue damage while maintaining overall treatment effectiveness.
Solution Approach 2:
The patent changes the fundamental parameters of the optical system by using multiple wavelengths (including 635 nm red light and other visible spectrum wavelengths) instead of single-wavelength high-power lasers. This parameter change enables photomodulation of cytochrome c oxidase at the cellular level, achieving fat reduction through biochemical modulation rather than thermal destruction, thereby eliminating tissue damage risks.
2Speed
If conventional laser beams are used for fat treatment, then treatment speed is improved, but uniformity of treatment coverage deteriorates
Solution Approach 1:
The patent uses arrays of multiple optical emitters arranged in grid patterns rather than single laser beams. This segmentation allows simultaneous treatment of multiple areas, maintaining treatment speed while ensuring uniform energy distribution across the treatment zone through the coordinated operation of multiple emitters.
Solution Approach 2:
The patent combines multiple low-power optical emitters into a unified treatment system where their effects are merged at the tissue level. The cumulative photomodulation effect of multiple LEDs working in unison achieves the same biochemical response as high-power lasers while providing uniform coverage across the entire treatment area.
3Area of stationary object
If multiple high-power lasers are used to treat larger areas, then treatment coverage is improved, but risk of eye damage and uneven results increases
Solution Approach 1:
The patent segments the optical treatment function across multiple low-power LED emitters distributed over a large area, eliminating the need for multiple high-power lasers. This segmentation approach provides broad treatment coverage while each individual emitter operates at safe power levels that pose no eye damage risk.
Solution Approach 2:
The patent replaces the mechanical laser beam system with an optical LED array system. This substitution eliminates the coherent, highly concentrated laser beams that pose eye damage risks, while the incoherent, distributed LED emissions provide safe yet effective treatment over large areas through photomodulation mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively decreases lipid content in adipocytes, promotes collagen and elastin production, and reduces visceral fat without adverse effects, offering a safer and more efficient alternative to existing methods with improved uniformity and safety.
Implementation Method 1
The optical output may be generated by a plurality of LED's cumulatively producing red light at approximately 635 nm
Implementation Method 2
Dr. Karu's results obtained evidence that cytochrome coxidase becomes more oxidized (which means that the oxidative metabolism is increased) due to irradiation at all wavelengths used. The results of that experiment supports the suggestion (Karu, Lasers Life Sci., 2:53, 1988) that the mechanism of low-power laser therapy at the cellular level is based on the electronic excitation of chromophores in cytochrome c oxidase which modulates a redox status of the molecule and enhances its functional activity.
