Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional high gradient magnetic separator is used to sort magnetically attractable and non-magnetically attractable substances, then separation function is achieved, but separation accuracy and separation efficiency are insufficient due to retention of unsorted substances in the magnetic separation flow path
Solution Approach 1:
The magnetic separation flow path is divided into multiple sections with different flow path cross-sectional areas. The flow path cross-sectional area is set to be larger at the introduction side than at the discharge side, creating distinct zones for different separation functions. This segmentation allows unsorted substances to be effectively managed while maintaining high separation accuracy.
Solution Approach 2:
The invention introduces a dimensional change in the flow path cross-sectional area along the flow direction. By varying the cross-sectional area from larger at the introduction side to smaller at the discharge side, the system creates a gradient flow pattern that enhances separation efficiency and prevents retention of unsorted substances.
2Productivity
If conventional magnetic separation flow path is used, then basic separation is achieved, but separation efficiency is reduced due to unintentional inclusion of unsorted substances
Solution Approach 1:
The flow path configuration dynamically adjusts the flow characteristics by varying the cross-sectional area. This creates a dynamic flow pattern where fluid velocity and pressure change along the flow path, enabling effective separation of magnetically attractable and non-magnetically attractable substances while preventing retention of unsorted materials.
Solution Approach 2:
The invention changes the geometric parameter of the flow path (cross-sectional area) along the flow direction. This parameter change creates a gradient effect that enhances the separation process, improving both separation efficiency and accuracy by preventing the retention of unsorted substances in the flow path.
