Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an impenetrable separation element is arranged between the hydraulic portion and the magnet portion to prevent dirt particles from reaching the magnet portion, then contamination protection is improved, but response properties and fluid circulation are worsened
Solution Approach 1:
The divider element is designed with porous structure or flow connections that allow hydraulic fluid to pass through while still providing separation. This enables the divider element to filter contaminants from the fluid while maintaining adequate fluid flow to the magnet portion, thus protecting against contamination without compromising response properties
Solution Approach 2:
The divider element acts as an intermediary component between the hydraulic portion and the magnet portion. It provides a controlled interface that allows selective passage of fluid while blocking contaminants, mediating between the need for contamination protection and the need for fluid circulation
2Reliability
If a direct connection of the magnet portion and hydraulic portion is provided to facilitate fluid circulation, then response properties are improved, but contamination risks increase
Solution Approach 1:
The divider element introduces local quality differentiation by creating zones with different contamination levels. The side facing the hydraulic portion handles contaminated fluid while the side facing the magnet portion provides a cleaner environment, allowing direct connection benefits while mitigating contamination risks through localized filtration
3Ease of manufacture
If the divider element is made from synthetic materials with deformable sections for easy assembly, then ease of manufacture is improved, but structural strength may be reduced
Solution Approach 1:
The deformable section of the divider element is designed to be elastically deformable during assembly but maintains sufficient structural strength during operation. The dynamic property allows the element to be compressed or deformed for installation while returning to its original shape to provide the required separation and flow control functions
