Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single beam is used for tissue treatment, then the treatment is simple and easy to control, but it cannot simultaneously treat different layers of tissue with varying penetration and thermal effects
Solution Approach 1:
The electromagnetic beam is segmented into multiple beams with different wavelengths (e.g., first beam at 1064 nm, second beam at 532 nm) that can penetrate to different depths in tissue. Each beam targets specific tissue layers independently, enabling simultaneous treatment of multiple layers without increasing overall system complexity.
Solution Approach 2:
A single therapeutic electromagnetic system is designed to generate multiple beams with different wavelengths and penetration depths. The system maintains a unified control structure while achieving multi-functional capability to treat various tissue layers (epidermis, dermis, subcutaneous tissue) simultaneously.
2Reliability
If multiple beams with different wavelengths are applied simultaneously, then treatment efficacy is enhanced, but the system complexity and control difficulty increase
Solution Approach 1:
Different wavelengths are assigned to target specific tissue layers based on their absorption characteristics. For example, 1064 nm beam penetrates deeper to treat dermal layers while 532 nm beam targets superficial epidermal structures. This local optimization of beam properties enhances treatment efficacy for each specific tissue layer.
Solution Approach 2:
The system pre-configures multiple beams with optimized wavelengths and parameters before treatment begins. The control system is programmed with predetermined settings for each beam based on the desired treatment depth and tissue type, reducing real-time control complexity while maintaining high treatment efficacy.
3Temperature
If laser pulse duration is extended for thermal effects, then tissue coagulation is achieved, but adjacent tissue damage increases
Solution Approach 1:
The treatment is divided into multiple beams with different pulse durations tailored to specific tissue depths. Shorter pulses (nanoseconds to microseconds) are used for superficial layers to minimize heat diffusion, while longer pulses (milliseconds) are used for deeper layers where thermal coagulation is desired. This segmented approach confines thermal effects to target zones.
Solution Approach 2:
The system dynamically adjusts pulse duration parameters for each beam based on the target tissue layer. By changing the temporal parameter of the electromagnetic energy delivery, the system achieves precise thermal control - using shorter pulses to limit heat spread to adjacent tissues and longer pulses when deeper coagulation is required.
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
Enables precise and efficient treatment of tissues by allowing for the simultaneous application of multiple energy beams with varying wavelengths and modes, enhancing treatment efficacy and reducing tissue damage.
Implementation Method 1
featuring transmitting windows with antireflective coatings
Implementation Method 2
Some wavelengths of laser energy are preferentially absorbed in a particular type of tissue when the tissue contains a particular chromophore that has a peak or relatively high absorption at the particular wavelength. After being absorbed in the tissue, laser energy transforms into thermal energy and results in a rise of temperature.
Implementation Method 3
Use of a laser beam matched to a peak or relatively high absorption in tissue to treat the tissue is referred to as 'selective photothermolysis.'
Implementation Method 4
Temperature increase leads to tissue coagulation.
Implementation Method 5
If the laser pulse is very short (typically between several nanoseconds [10-9 seconds] and one microsecond [10-6 seconds]) the tissue may be damaged due to explosion or evaporation in the area of laser absorption.
