Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If focused ultrasound technique is used to remove subcutaneous fat, then fat removal effect and use safety are improved, but device complexity and treatment adaptability to different skin conditions deteriorate
Solution Approach 1:
The patent implements dynamic adaptability by enabling the control unit to adjust treatment parameters (ultrasound energy intensity, vibration frequency, electrical current) based on real-time skin impedance measurements. The system dynamically modifies treatment conditions to match different skin types and fat distribution patterns, transforming a static focused ultrasound device into an adaptive treatment system that maintains safety while improving versatility.
Solution Approach 2:
The patent combines multiple treatment modalities (focused ultrasound, vibration energy, electrical energy, drug injection) into a single integrated device. This multi-functional approach allows one device to address various skin conditions and fat removal needs, replacing the need for multiple separate devices and improving treatment adaptability across different clinical scenarios.
2Productivity
If high-energy ultrasound vibration is transmitted to rupture fat cell membranes, then fat removal effect is improved, but risk of skin surface burning increases
Solution Approach 1:
The patent incorporates real-time feedback through skin impedance measurement using electrode units. The control unit continuously monitors skin impedance during treatment and uses this feedback to adjust the intensity of ultrasound and electrical energy delivery. This closed-loop control prevents excessive energy accumulation at the skin surface, thereby preventing burning while maintaining effective fat removal.
Solution Approach 2:
The patent dynamically changes treatment parameters (energy intensity, frequency, duration) based on real-time skin impedance measurements. By adjusting these parameters according to actual skin conditions rather than using fixed high-energy settings, the system maintains effective fat cell rupture while preventing skin surface damage.
3Productivity
If vibration energy intensity is increased to improve treatment efficacy, then fat removal effectiveness is improved, but skin impedance variation causes inconsistent treatment results
Solution Approach 1:
The patent uses skin impedance measurement as a feedback mechanism to determine the appropriate vibration energy intensity. The control unit measures skin impedance before and during treatment, then adjusts energy delivery to achieve consistent therapeutic effects across different patients and skin conditions. This feedback-based parameter adjustment ensures reliable and repeatable treatment outcomes.
Solution Approach 2:
The patent changes vibration energy intensity parameters based on measured skin impedance values. By establishing a relationship between skin impedance and optimal energy intensity, the system automatically adjusts parameters to maintain consistent treatment efficacy regardless of individual patient variations in skin properties.
