Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional plasma beauty care devices are used, then skin treatment function is provided, but portability is poor and safety is compromised
Solution Approach 1:
The device is divided into a handle portion and a treatment portion that can be detached. The treatment portion with the electrode unit can be separated from the handle, allowing flexible configuration that improves both portability and safety by enabling the use of a lighter, simpler treatment head while maintaining the power source in the handle.
Solution Approach 2:
A dielectric member (insulating layer) is introduced between the first and second electrodes. This intermediary prevents direct contact between electrodes, ensuring safety by preventing electric shock while still allowing plasma generation through dielectric barrier discharge. The dielectric member acts as a safety mediator that enables portable design without compromising user protection.
2Reliability
If atmospheric pressure plasma is generated for skin treatment, then skin density and elasticity are improved, but device complexity increases
Solution Approach 1:
The device operates at atmospheric pressure without requiring vacuum conditions, and uses a dielectric barrier discharge mode that generates plasma at lower temperatures. These parameter changes (pressure, temperature, discharge mode) enable effective skin treatment while simplifying the device structure by eliminating complex vacuum systems and high-temperature control mechanisms.
Solution Approach 2:
The dielectric member is configured as a thin film or layer between the electrodes. This thin film structure provides the necessary insulation for safety and plasma generation while minimizing the overall device thickness and complexity. The flexible thin film design allows for compact integration into the portable device structure.
3Reliability
If dielectric barrier discharge is used to generate plasma, then safety is improved through reduced temperature, but manufacturing complexity increases
Solution Approach 1:
By changing the discharge mode to dielectric barrier discharge and operating at atmospheric pressure, the plasma generation temperature is reduced to safe levels for skin treatment. While this introduces a dielectric member, the overall manufacturing becomes simpler by eliminating vacuum systems, high-temperature materials, and complex cooling mechanisms required in conventional plasma devices.
Solution Approach 2:
The dielectric member can be designed as a thin, inexpensive layer that is easy to manufacture and replace. This approach simplifies the manufacturing process by using readily available insulating materials rather than requiring complex high-temperature resistant components, making the device more manufacturable despite the added layer.
