Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple nozzles with multiple movable axes are used to perform aspiration and discharge operations, then operational versatility is improved, but device complexity and size increase
Solution Approach 1:
The magnetic separation portion is designed to perform multiple functions: it separates magnetic particles from the reaction solution, positions the separated solution for aspiration, and enables discharge operations. By making the magnetic separation portion itself movable in vertical and horizontal directions, it becomes a multi-functional component that replaces what would traditionally require separate nozzles and multiple actuators, thereby reducing the number of movable axes while maintaining operational versatility
Solution Approach 2:
The patent combines the magnetic separation function with the solution transfer function into a single integrated system. The magnetic separation portion that normally would be stationary is now made movable, merging the separation operation with the aspiration and discharge operations into one coordinated mechanism, reducing the need for separate nozzle assemblies and their associated movable axes
2Manufacturing precision
If multiple nozzles with independent movement control are implemented, then operational precision is improved, but device size and cost increase
Solution Approach 1:
The movable magnetic separation portion serves as a universal platform that achieves precise solution transfer through its controlled movement in vertical and horizontal directions. This single multi-functional mechanism replaces multiple specialized nozzles with independent movement control, maintaining precision while reducing the overall device size and eliminating redundant components
Solution Approach 2:
The magnetic separation portion acts as an intermediary mechanism between the reaction container and the aspiration/discharge system. By controlling the position of this intermediary component, the system achieves precise solution transfer without requiring multiple independently controlled nozzles, thereby reducing device complexity and size while maintaining operational precision
