Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If needle-shaped electrification pins are used, then electrification function is achieved, but harmful ozone is generated
Solution Approach 1:
The invention changes the geometric parameters of the electrification element from needle-shaped pins to plate-shaped structures with rounded edges. This parameter change eliminates the sharp points that generate harmful ozone while maintaining the electrification function through the conductive microfiber layer on the plate surface.
Solution Approach 2:
The invention replaces durable but harmful needle-shaped pins with a conductive microfiber layer that can be easily replaced. The microfiber layer serves as a disposable or easily renewable electrification surface that prevents ozone generation while maintaining functionality.
2Ease of manufacture
If electrification plate and electrification pin are assembled separately, then assembly flexibility is improved, but relative position stability deteriorates
Solution Approach 1:
The invention merges the electrification plate and collector plate into a single integrated structure with grooves formed directly in the plate. This eliminates the separate assembly of pins and plates, ensuring consistent relative positions while maintaining manufacturing ease through single-piece fabrication or pre-formed groove structures.
Solution Approach 2:
The grooves for holding conductive microfiber are pre-formed in the plate structure before final assembly. This preliminary action ensures correct positioning of the electrification elements without requiring complex alignment during assembly, thus maintaining both ease of manufacture and position consistency.
3Manufacturing precision
If conductive microfiber is installed on frame with grooves, then positioning accuracy is improved, but installation complexity increases
Solution Approach 1:
The invention segments the plate into regions with grooves that hold conductive microfiber bundles. This segmentation provides clear positioning guides for installing microfiber while keeping the overall structure simple and modular, thus improving positioning accuracy without significantly increasing installation complexity.
