Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional air filtration methods are used, then dust and odor can be filtered, but air flow resistance increases and filtering effect decreases over time
Solution Approach 1:
The patent replaces the mechanical filtration system with a plasma ionization system. Instead of using physical filters that block particles, the invention uses plasma to ionize air molecules and charged particles to naturally migrate and collect pollutants, eliminating the need for mechanical filter media and maintaining consistent air flow without increasing resistance.
Solution Approach 2:
The patent changes the physical and chemical parameters of air molecules through plasma ionization. By applying high voltage to create plasma, the system transforms neutral air molecules into ionized states, enabling them to actively interact with and neutralize pollutants, thereby improving purification effectiveness without mechanical resistance.
2Reliability
If plasma air purifier uses board-to-board or wire-to-board structure, then ionization can be achieved, but purification speed is slow and fan assistance is required
Solution Approach 1:
The patent segments the electrode structure into multiple needle-like conductors arranged in arrays rather than using single board-to-board or wire-to-board configurations. This segmentation increases the total ionization surface area and creates multiple plasma discharge points, significantly enhancing purification speed without requiring fan assistance.
Solution Approach 2:
The patent transitions from two-dimensional board-to-board structures to a three-dimensional spatial arrangement of needle-like conductors. The needles extend into the air space, creating plasma fields in multiple dimensions and greatly increasing the effective ionization volume, which accelerates purification without mechanical assistance.
3Reliability
If integrated board structure is used for electrostatic precipitation, then dust collection can be achieved, but the device is not easy to set up and clean
Solution Approach 1:
The patent divides the electrode system into separate, modular needle-like conductors that can be independently positioned and adjusted. This segmentation allows for easy setup by simply placing the needle arrays into designated positions and enables simple cleaning by removing and washing individual components, eliminating the complexity of integrated board structures.
