Solution Overview
Problem
Current wound healing processes are inefficient in delivering therapeutic agents like Vitamin C transdermally, particularly in optimizing the phases of wound healing, inflammation, proliferation, and remodeling, due to limitations in existing delivery methods.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional transdermal delivery methods are used, then the device structure remains simple, but the delivery efficiency of therapeutic agents through the skin is insufficient
Solution Approach 1:
The patent combines multiple therapeutic modalities (ultrasound, light therapy, heat/cold therapy) into a single integrated device that simultaneously delivers therapeutic agents through the skin. This merging of functions resolves the contradiction by achieving high delivery efficiency through multiple synergistic mechanisms while accepting the necessary increase in device complexity as a trade-off for superior performance.
Solution Approach 2:
The device is designed to perform multiple functions: mechanical vibration for sonophoresis, light therapy for photopheresis, and heat/cold therapy for thermal modulation. This multi-functionality enables the device to address various barriers to transdermal delivery simultaneously, improving overall delivery efficiency while consolidating multiple therapeutic actions into one universal platform.
2Reliability
If mechanical vibration and light therapy are combined, then the penetration of therapeutic agents is enhanced, but the device complexity increases
Solution Approach 1:
The patent integrates mechanical vibration elements (ultrasonic transducers) and light therapy components (LED arrays or laser sources) into a unified device structure. This merging allows simultaneous application of sonophoresis and photopheresis mechanisms, enhancing therapeutic agent penetration through complementary physical effects while managing the complexity through integrated design.
3Productivity
If multiple therapy modalities are synchronized, then the wound healing process is optimized, but the control system complexity increases
Solution Approach 1:
The device employs periodic or pulsed delivery of different therapy modalities (ultrasound pulses, light pulses, thermal cycles) in coordinated sequences. This periodic action allows optimization of wound healing at different phases (inflammation, proliferation, remodeling) while managing control complexity through programmable timing patterns rather than continuous multi-parameter control.
Solution Approach 2:
The control system dynamically adjusts the intensity, duration, and sequencing of different therapy modalities based on treatment phase and real-time feedback. This dynamic control optimizes wound healing efficiency by adapting treatment parameters to match the evolving needs of tissue repair while managing complexity through adaptive algorithms rather than fixed rigid control.
