Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ultrasonic waves are radiated at a single pattern and intensity, then the device structure is simple, but treatment customization according to skin characteristics is not possible
Solution Approach 1:
The transducer is made movable in both X-axis and Y-axis directions through driving devices (linear motor and rotation motor), allowing dynamic adjustment of ultrasonic wave radiation patterns. This enables the system to switch between different treatment patterns (spiral, zigzag, wave shapes) and intensities, achieving treatment customization without requiring multiple static transducer configurations
Solution Approach 2:
The patent introduces two-dimensional movement capability (X-axis and Y-axis directions) to the transducer, transforming the traditional single-direction or fixed radiation pattern into a multi-dimensional adjustable system. This dimensional expansion allows complex radiation patterns to be generated by coordinating movements in both axes, enabling diverse treatment approaches from a single transducer
2Manufacturing precision
If simple ultrasonic wave radiation is used, then the device is easy to operate, but delivering ultrasonic energy to various layers of dermis is difficult
Solution Approach 1:
The control system receives information about skin characteristics and treatment purposes, then automatically adjusts transducer movement parameters and ultrasonic wave intensity. This feedback mechanism enables precise energy delivery to specific dermal layers by coordinating transducer position (through X-axis and Y-axis movement) with radiation intensity, achieving accurate depth targeting without requiring manual calibration by the operator
3Productivity
If high-intensity ultrasonic waves are radiated more than necessary, then treatment coverage is increased, but damage to skin tissue may be caused
Solution Approach 1:
The system applies different ultrasonic wave intensities to different regions and depths of the skin based on treatment requirements. By controlling transducer movement in X-axis and Y-axis directions while modulating intensity, the system can concentrate energy where needed (increasing treatment coverage) while maintaining lower intensities in surrounding areas, thereby avoiding unnecessary tissue damage and side effects
