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 occur
Solution Approach 1:
The handpiece is divided into multiple functional modules: transducer unit for ultrasound generation, thermoelectric cooling unit for temperature control, and electrode unit for impedance measurement. Each module operates independently but coordinates through the control unit, enabling safe fat removal while managing device complexity through modular design.
Solution Approach 2:
The device incorporates a feedback mechanism where the electrode unit measures skin impedance and transmits this information to the control unit, which then adjusts the intensity of vibration energy accordingly. This closed-loop feedback system ensures adaptability to varying skin conditions while maintaining safety, resolving the contradiction between reliability and device complexity.
2Productivity
If vibration energy intensity is increased for better fat removal, then treatment efficacy is improved, but skin burning and damage to surrounding tissues occur
Solution Approach 1:
The device converts the potentially harmful thermal effect of high-intensity vibration energy into a beneficial cooling effect by introducing a thermoelectric element that actively cools the handpiece surface. This allows the system to deliver high-intensity vibration energy for effective fat removal while preventing skin burning through active thermal management.
Solution Approach 2:
The thermoelectric element acts as an intermediary between the vibration energy source and the skin surface. It mediates the thermal interaction by absorbing excess heat and dissipating it, thereby enabling high-intensity treatment without direct thermal damage to the skin. This intermediary component resolves the contradiction between treatment efficacy and skin safety.
3Ease of operation
If fixed treatment parameters are used for simplicity, then ease of operation is improved, but adaptability to varying skin conditions deteriorates
Solution Approach 1:
The device performs self-measurement of skin impedance through the electrode unit and automatically adjusts vibration energy intensity based on the measured values. This self-service capability eliminates the need for manual parameter adjustment by the operator, maintaining ease of operation while achieving high adaptability to varying skin conditions through automated feedback control.
