Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional micro-plasma technology is used for skin tissue applications, then plasma treatment can be achieved, but thermal effects cause prolonged wound healing and increased risk of complications
Solution Approach 1:
The patent changes the physical parameters of plasma by using specific gas compositions (helium or argon as base gas with 1-10% oxygen or nitrogen) and controlling power density (10-100 W/cm²) to achieve low-temperature plasma with reduced thermal effects while maintaining therapeutic efficacy for wound healing
Solution Approach 2:
The patent uses inert or weakly reactive gases (helium or argon) as the primary plasma generation gas to create a controlled atmosphere that minimizes unwanted thermal effects and chemical reactions, while adding small amounts of reactive gases (oxygen or nitrogen) to provide beneficial biological effects without excessive heating
2Power
If high power is used to generate micro-plasma, then plasma excitation is achieved, but energy consumption increases and temperature rises
Solution Approach 1:
The patent optimizes the balance between power input and plasma temperature by using specific gas compositions and power densities (10-100 W/cm²), achieving effective plasma excitation for wound healing while maintaining low overall energy consumption and controlled temperature
Solution Approach 2:
The patent employs continuous or pulsed plasma delivery modes that maintain therapeutic effectiveness while optimizing energy utilization, ensuring continuous beneficial effects on wound tissue without excessive energy input or temperature accumulation
