Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ozone is supplied to treat moving objects, then sterilization effect is improved, but treatment efficiency is limited due to short lifespan of reactive oxygen
Solution Approach 1:
The plasma actuator generates ozone in advance and directs it through an induced flow toward the treatment target. This preliminary generation and directional delivery ensures that reactive oxygen reaches the moving objects effectively, resolving the contradiction between maintaining sterilization reliability and improving treatment efficiency for moving objects
Solution Approach 2:
The invention uses an induced flow (aerodynamic mechanism) to transport ozone from the plasma actuator to the treatment area. This pneumatic delivery system maintains the reactive state of oxygen species during transit, enabling effective treatment of moving objects while preserving both sterilization effect and treatment efficiency
2Reliability
If ultraviolet rays and ozone are used for surface treatment, then treatment effect is increased, but effectiveness on moving objects is limited
Solution Approach 1:
The invention replaces the conventional ultraviolet lamp system with a plasma actuator that generates ozone and induces directed flow. This substitution creates a mobile-friendly treatment mechanism that can effectively treat moving objects while maintaining high treatment effect, as the induced flow adapts to the movement of objects
Solution Approach 2:
The induced flow generated by the plasma actuator is dynamic and can adapt to moving objects. The flow direction and intensity can be adjusted to track and treat moving objects effectively, resolving the limitation of static ultraviolet-based systems when treating moving targets

Implementation Method 1
When a voltage is applied between the first electrode and the second electrode, the plasma actuator generates a dielectric barrier discharge from the first electrode to the second electrode
Implementation Method 2
the ozone decomposing device generates reactive oxygen in the induced flow by decomposing the ozone contained in the induced flow
