Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional plasma discharge technologies are used for surface treatment, then treatment can be performed on objects, but uniform discharge is not achieved throughout the entire inside of the container
Solution Approach 1:
The container is divided into multiple discharge zones with multiple electrode portions (first electrode portion and second electrode portion) positioned at different locations. Each electrode generates plasma discharge independently, ensuring uniform treatment across the entire container interior including remote areas that would otherwise be difficult to reach with a single discharge source.
Solution Approach 2:
The invention transitions from conventional single-point or single-plane discharge to multi-dimensional discharge by positioning electrode portions at different spatial locations and orientations within the container. This includes electrodes on opposite walls or at different heights, creating discharge paths that cover the three-dimensional interior space uniformly.
2Reliability
If treatment targets are stored in packaging containers, then sterility and surface activation state can be maintained, but contamination or damage may occur during packaging, transportation, and opening
Solution Approach 1:
The treatment target undergoes plasma surface treatment and achieves a sterile, activated state before being placed in the packaging container. This preliminary treatment ensures that the surface is already in the desired hydrophilic state and sterile condition, maintaining these properties throughout storage and transportation without requiring additional protective measures during handling.
Solution Approach 2:
The packaging container is filled with an inert atmosphere (such as nitrogen or vacuum) to prevent contamination and oxidation of the treated surface during storage and transportation. This inert environment protects the sterility and surface activation state of the treatment target until the moment of use.
3Productivity
If dielectric-barrier discharge is generated through the permeable portion, then plasma treatment efficiency is improved, but stable electrical connection must be maintained
Solution Approach 1:
An electrical connection member serves as an intermediary element that bridges the external power source and the electrode portion inside the packaging container. This dedicated connection member ensures stable electrical contact while allowing the dielectric-barrier discharge to occur efficiently through the permeable portion, resolving the conflict between connection reliability and discharge efficiency.
Solution Approach 2:
The permeable portion is designed as a thin film or porous structure that allows electrical field penetration while maintaining the packaging's protective function. This thin film structure enables dielectric-barrier discharge to occur through it without compromising the electrical connection stability, as the connection is established through separate dedicated pathways rather than through the permeable material itself.
