Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only electromagnetic attraction and repulsion forces are used for centering the specimen holder, then the device complexity is reduced, but the centering accuracy deteriorates due to weight and frictional forces
Solution Approach 1:
A pressing mechanism with a pressing member is introduced as an intermediary device between the electromagnetic actuator and the specimen holder. The pressing member contacts the specimen holder to apply mechanical pressure, correcting positional errors caused by weight and friction. This intermediary mechanical connection ensures accurate centering without requiring complex electromagnetic control systems.
2Ease of operation
If the specimen holder is positioned inaccurately, then the ease of operation is improved by reducing control complexity, but the reliability deteriorates due to potential specimen container mishandling
Solution Approach 1:
The pressing mechanism serves as a reliable intermediary that mechanically ensures the specimen holder is accurately positioned at the center of the electromagnetic actuator. This mechanical guarantee prevents specimen container mishandling during insertion or removal operations, thereby improving reliability without complicating the control system.
Solution Approach 2:
The pressing member applies mechanical pressure beforehand to correct any positional deviations before the specimen holder is used. This preventive measure ensures that the specimen holder is accurately centered prior to any operations, preventing potential mishandling and ensuring reliable specimen container insertion or removal.
