Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If electrostatic atomization method is used to generate nano-sized mist, then nanoparticle formation is achieved, but a closed circuit with high voltage is required which increases device complexity and safety risks
Solution Approach 1:
The patent extracts the ground electrode from the external environment and integrates it into the device structure itself. The ground electrode is provided on the outer periphery of the discharge tube, forming a self-contained system that eliminates the need for external grounding circuits while maintaining the necessary electrical field for nanoparticle generation
Solution Approach 2:
The dielectric discharge tube serves as an intermediary component that enables plasma generation without direct high-voltage contact with the target. The dielectric material isolates the high voltage from the external environment while still allowing the necessary electrical discharge to occur, thereby reducing safety risks and device complexity
2Quantity of substance
If ultrasonic wave method is used to generate mist, then atomization is achieved, but an atomization mechanism such as ultrasonic transducer is required which increases device complexity
Solution Approach 1:
The patent replaces the mechanical ultrasonic atomization system with an electrical plasma-based system. Instead of using mechanical vibrations from an ultrasonic transducer to atomize the liquid, the invention uses dielectric barrier discharge to generate plasma that directly interacts with the liquid to form nanoparticles, thereby eliminating complex mechanical atomization mechanisms
Solution Approach 2:
The patent changes the fundamental parameter from mechanical vibration (ultrasonic frequency) to electrical discharge (voltage and current). By applying high voltage to the electrode within the dielectric discharge tube, plasma is generated which then interacts with the liquid feed to produce nanoparticles, representing a complete parameter transformation from mechanical to electrical domain
3Reliability
If direct plasma action is applied to the lesion, then treatment effectiveness is improved, but surgical burden on the patient increases
Solution Approach 1:
The patent creates a copy or replica of plasma effects through nanoparticle delivery. Instead of applying direct plasma to the tissue (which would cause surgical burden), the system generates plasma-derived nanoparticles that can be delivered to the target site, replicating the beneficial biological effects of plasma while avoiding its harmful thermal and mechanical impacts
Solution Approach 2:
The patent introduces nanoparticles as an intermediary carrier between the plasma generation system and the target tissue. These nanoparticles serve as a mediator that transports the therapeutic effects of plasma to the lesion site without requiring direct plasma-tissue contact, thereby maintaining treatment effectiveness while reducing surgical burden
