Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If focused ultrasound technique is used for subcutaneous fat removal, then fat removal effect and use safety are improved, but device complexity and lack of adaptability to varying skin conditions worsen
Solution Approach 1:
The patent implements dynamic adaptability by equipping the handpiece with sensors that detect skin conditions in real-time and automatically adjust treatment parameters. The control unit modifies energy intensity, frequency, and other operational parameters based on detected skin characteristics, allowing the device to adapt to varying skin conditions while maintaining safety and effectiveness.
Solution Approach 2:
The patent incorporates feedback mechanisms through sensors that continuously monitor skin conditions during treatment. The detected information is fed back to the control unit, which adjusts treatment parameters accordingly. This closed-loop control system enables the device to respond to skin condition variations, resolving the contradiction between maintaining fixed focused ultrasound parameters and adapting to different skin types.
2Productivity
If focused ultrasound technique is used for subcutaneous fat removal, then fat removal effect is improved, but device complexity and inability to offer multiple treatment methods worsen
Solution Approach 1:
The patent achieves multi-functionality by integrating multiple treatment modalities into a single handpiece. The device can switch between focused ultrasound treatment and other treatment methods such as radiofrequency or optical treatments. The control unit manages different treatment modes, allowing the device to offer multiple treatment approaches while maintaining the effective fat removal capability of focused ultrasound.
3Productivity
If high-energy ultrasound vibration is applied to rupture fat cell membranes, then fat removal effect is improved, but risk of skin surface burning worsens
Solution Approach 1:
The patent applies local quality differentiation by directing high-energy ultrasound vibrations specifically to the subcutaneous fat layer while using cooling mechanisms to protect the skin surface. The treatment energy is localized to the target depth, and the handpiece incorporates cooling elements that maintain skin surface temperature within safe limits, allowing effective fat cell membrane rupture without skin burning.
Solution Approach 2:
The patent implements protective measures before treatment by incorporating cooling systems in the handpiece that preemptively cool the skin surface during high-energy ultrasound delivery. This prior cushioning approach prevents skin surface burning by maintaining thermal protection throughout the treatment process, enabling effective fat removal with reduced harmful effects.
