Engineering Contradiction Analysis
1Power
If conventional portable plasma devices are designed for skin beauty applications, then the device form factor is compact and portable, but the plasma intensity is weak and unsuitable for biomedical field
Solution Approach 1:
The device is divided into distinct functional modules: a power supply unit, a plasma generation unit with electrode structure, and a control unit. This segmentation allows each module to be optimized independently - the plasma generation unit can be designed for high intensity while the overall device maintains portability through modular architecture.
Solution Approach 2:
The device incorporates adjustable plasma emission capabilities through controllable gas flow rates and variable power supply settings. This dynamic control allows the plasma intensity to be adjusted according to different biomedical application requirements, transforming a static low-intensity device into a dynamically adaptable high-intensity system.
2Ease of operation
If the plasma device is designed with fixed emission characteristics, then the device structure is simple, but it is difficult to adjust plasma intensity according to user intention
Solution Approach 1:
The device incorporates adjustable plasma emission capabilities through controllable gas flow rates and variable power supply settings. This dynamic control allows the plasma intensity to be adjusted according to different biomedical application requirements, transforming a static low-intensity device into a dynamically adaptable high-intensity system.
Solution Approach 2:
The device allows adjustment of plasma emission parameters including gas flow rate, power supply voltage, and electrode positioning. By changing these physical parameters, the plasma intensity and characteristics can be optimized for different biomedical tasks without requiring complex mechanical reconfiguration.
3Manufacturing precision
If conventional plasma devices use needle electrode structure with external gas injection, then plasma generation is achieved, but uniform and local treatment of microstructure inner surfaces is difficult
Solution Approach 1:
The device incorporates a gas injection system with multiple nozzles positioned at specific locations around the electrode structure. This allows localized gas delivery to specific regions of the plasma zone, enabling selective and uniform treatment of different areas of microstructure inner surfaces such as microwell plates.
Solution Approach 2:
The invention transitions from a simple linear needle electrode to a three-dimensional electrode structure with gas nozzles positioned at multiple spatial coordinates. This dimensional expansion creates a distributed plasma field that can uniformly treat complex microstructure geometries from multiple angles simultaneously.
4Weight of moving object
If the plasma device is miniaturized for portability, then the device becomes convenient to carry, but the plasma flame control and uniform treatment capability is reduced
Solution Approach 1:
The device uses a high-energy-density power supply system that delivers sufficient power for strong plasma emission in a compact form. By optimizing the electrical parameters and using efficient conversion circuits, the device achieves high plasma intensity without requiring a large power supply unit, thus maintaining portability.
Solution Approach 2:
The device is divided into distinct functional modules: a power supply unit, a plasma generation unit with electrode structure, and a control unit. This segmentation allows each module to be optimized independently - the plasma generation unit can be designed for high intensity while the overall device maintains portability through modular architecture.
