Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If non-flexible electrodes are used to generate plasma, then plasma discharge can be achieved, but system design flexibility and adaptability are restricted
Solution Approach 1:
The patent applies flexible thin film electrodes that can be bent and shaped to conform to various surfaces, replacing rigid electrode structures. This enables the plasma generation system to be adapted to different geometries and applications while maintaining electrical functionality for plasma discharge.
Solution Approach 2:
The electrode structure transitions from static and rigid to dynamic and flexible, allowing the electrodes to be positioned and shaped as needed for different treatment areas and configurations, enhancing system adaptability without compromising structural integrity.
2Power
If helium or argon gas is supplied for plasma discharge, then discharge voltage is reduced, but supply gas facilities are additionally required
Solution Approach 1:
The system utilizes ambient air as the plasma discharge medium, eliminating the need for external gas supply facilities. The electrode structure is designed to generate plasma directly from atmospheric air, making the system self-sufficient and removing complex gas handling infrastructure.
Solution Approach 2:
The requirement for external gas supply is extracted and removed from the system by designing electrodes that can sustain plasma discharge using ambient air, thereby simplifying the overall system architecture while maintaining plasma generation capability.
3Productivity
If DBD-type or torch-type electrode structures are used in atmospheric pressure plasma, then plasma can be generated, but treatment sectional area remains small
Solution Approach 1:
The electrode system is divided into multiple flexible electrode elements that can be arranged and configured to cover large treatment areas. These segmented electrodes work in parallel to expand the effective plasma generation area while maintaining manageable individual component sizes.
Solution Approach 2:
The electrode configuration transitions from conventional two-dimensional planar structures to three-dimensional flexible arrangements that can wrap around or conform to large surfaces, effectively increasing the treatment sectional area through spatial optimization.
