Engineering Contradiction Analysis
1Reliability
If plasma treatment is applied to titanium surface, then cell adhesion ability and antibacterial effect are improved, but treatment process complexity increases
Solution Approach 1:
The patent applies plasma treatment with controlled parameters (gas type, power, treatment time) to modify the titanium surface properties. By optimizing these parameters, the surface achieves enhanced cell adhesion and antibacterial effects without requiring complex multi-step processes. The plasma treatment directly modifies surface chemistry and morphology through controllable physical-chemical reactions.
Solution Approach 2:
The patent replaces traditional mechanical or chemical surface modification methods with plasma treatment. Instead of using mechanical roughening or chemical etching, the plasma process uses ionized gas to directly modify the surface, simplifying the treatment system while achieving superior surface properties for cell adhesion and antibacterial performance.
2Object-affected harmful factors
If plasma treatment is applied to titanium surface, then antibacterial effect is improved, but treatment time increases
Solution Approach 1:
The plasma treatment is applied in controlled periodic cycles with optimized duration. By using pulsed or cyclic plasma exposure rather than continuous treatment, the patent achieves effective antibacterial surface modification within a reduced time frame, preventing excessive treatment while ensuring sufficient bacterial inactivation.
Solution Approach 2:
The patent optimizes plasma treatment parameters including power density, gas composition, and exposure time to achieve rapid antibacterial effect. By adjusting these parameters, the treatment time is minimized while maintaining effective antibacterial performance, balancing treatment efficiency with clinical practicality.
