Solution Overview
Problem
Existing sample handling systems face limitations in magnetic manipulation due to the magnetic linkage between the upper and lower magnets, which restricts the movement and positioning of magnetic beads, leading to inefficient purification of biological analytes.
Innovation Solution
The introduction of a magnet management component with ridges and metal plates allows for independent placement and securing of the lower magnet, decoupling it from the upper magnet's position, enabling more robust and faster magnetic bead manipulation and purification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lower magnet is magnetically linked to the upper magnet, then the magnetic manipulation system is simple in structure, but the movement and positioning of magnetic beads is restricted
Solution Approach 1:
The magnetic manipulation system is divided into two independent magnet components: an upper magnet and a lower magnet. Each magnet can be independently positioned and controlled, allowing separate optimization of their functions. The lower magnet is secured by ridges that allow lateral movement but prevent vertical displacement, while the upper magnet maintains magnetic linkage. This segmentation enables independent positioning of each magnet to optimize magnetic bead manipulation without requiring the entire system to move together.
2Productivity
If the lower magnet is independently positioned, then the purification efficiency is improved, but the device structure becomes more complex
Solution Approach 1:
The lower magnet incorporates a self-positioning mechanism through ridges that are integrally formed with the box structure. These ridges automatically guide and secure the lower magnet laterally without requiring external positioning devices. The ridges allow the lower magnet to move laterally for positioning while preventing vertical displacement, enabling the system to achieve precise magnet positioning and fast purification speeds through the magnet's own structural features rather than complex external mechanisms.
3Manufacturing precision
If the lower magnet is secured with ridges, then the magnet positioning precision is improved, but the manufacturing complexity increases
Solution Approach 1:
The ridges for securing the lower magnet are integrally formed with the box structure itself, merging the positioning feature into the primary component. This integration eliminates the need for separate positioning devices or assemblies, allowing the ridges to be formed directly during box fabrication through molding or machining. The ridges serve dual purposes: securing the lower magnet laterally and providing a simple manufacturing feature that can be incorporated into the box production process, thereby maintaining ease of manufacture while achieving precise magnet positioning.
