Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the magnet is placed flat at the bottom of the cavity, then the device structure is simple, but the magnetic field near the abrasion zone is weak and particle collection efficiency is reduced
Solution Approach 1:
The magnet surface is transformed from a flat two-dimensional plane to a three-dimensional relief structure with raised areas. This dimensional change increases the effective surface area of the magnet that contacts particles, thereby enhancing the magnetic field's reach and strength in the particle generation zone without complicating the overall device structure.
Solution Approach 2:
The magnet surface is divided into different zones with varying heights - raised areas closer to the abrasion zone and lower areas farther away. This local differentiation concentrates the magnetic field strength where particles are generated, improving collection efficiency in the critical zone while maintaining structural simplicity overall.
2Device complexity
If the magnet is placed far from the front face of the lining, then the device structure is simplified, but the magnetic field strength near the abrasion zone is weak
Solution Approach 1:
By creating a relief structure on the magnet surface, the invention effectively reduces the distance between the magnet and the abrasion zone in the critical area without requiring complex repositioning mechanisms. The raised portions of the magnet surface extend closer to the particle generation zone, strengthening the magnetic field where it is most needed.
Solution Approach 2:
The magnet is designed with localized raised areas that position the magnetic field source closer to the abrasion zone specifically where particles are generated. This local optimization of magnetic field strength does not require moving the entire magnet assembly, thus maintaining structural simplicity while enhancing force in the critical zone.
3Productivity
If the magnet surface area in contact with particles is increased, then particle collection efficiency is improved, but the device structure becomes more complex
Solution Approach 1:
The magnet surface is given a relief structure with raised areas instead of remaining flat. This three-dimensional configuration increases the effective surface area available for particle attraction without adding separate components or complex assemblies. The relief structure is formed as an integral part of the magnet, avoiding additional complexity.
Solution Approach 2:
The magnet surface features localized raised areas concentrated in zones where particle contact is most beneficial. This selective increase in surface area at critical locations improves particle collection efficiency without uniformly complicating the entire magnet structure. The relief features are strategically positioned to maximize particle interaction while minimizing structural complexity.
