Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional fractional laser technology is used for skin treatment, then treatment coverage is provided, but the ability to effectively stimulate deep dermal structures is limited without aggressive parameters
Solution Approach 1:
The patent employs a sequence of sub-pulses delivered at high frequency (e.g., 1000 Hz or higher) within each composite pulse. This periodic action allows cumulative thermal energy delivery to deep dermal structures while maintaining minimally invasive surface parameters, effectively heating collagen and elastin fibers without requiring aggressive single-pulse settings.
Solution Approach 2:
The invention changes the temporal parameters of laser delivery by using composite pulses containing multiple sub-pulses at high frequency. This parameter transformation enables the system to achieve deep dermal heating effects equivalent to aggressive parameters while maintaining lower peak intensities at the skin surface, thereby stimulating collagen remodeling without excessive thermal damage.
2Reliability
If aggressive laser parameters are used to stimulate deep dermal structures, then treatment efficacy improves, but recovery time is prolonged and procedure invasiveness increases
Solution Approach 1:
The high-frequency sub-pulse sequence delivers thermal energy cumulatively to deep dermal structures over time, achieving reliable collagen stimulation and treatment efficacy. Simultaneously, the brief duration of each sub-pulse and the cooling intervals between composite pulses prevent excessive thermal damage to the epidermis, thereby reducing recovery time and procedure invasiveness.
Solution Approach 2:
The laser system performs preliminary heating of deep dermal structures through the sub-pulse sequence before significant thermal damage can occur at the surface. This preliminary action on the target tissue (collagen and elastin fibers) achieves the desired remodeling effect while the skin surface remains relatively protected, reducing post-treatment recovery time.
3Reliability
If multiple treatments are required to achieve desired results, then treatment thoroughness increases, but total treatment time and patient burden increase
Solution Approach 1:
The high-frequency sub-pulse sequence within each composite pulse delivers cumulative thermal energy that effectively stimulates deep dermal structures in a single treatment session. This periodic energy delivery pattern achieves treatment thoroughness comparable to or exceeding multiple conventional treatments, thereby reducing the total number of sessions required and decreasing overall patient burden.
