Magnetic Lid Lifter for Microplate Readers

The patent applies the dynamics principle by implementing an automated lid lifting mechanism that dynamically adjusts the lid position based on measurement requirements. The lid is automatically lifted during optical measurements to ensure accurate readings, then closed between measurements to prevent evaporation. This dynamic adjustment resolves the contradiction between maintaining sample volume and ensuring measurement accuracy.

The patent implements periodic action by automatically lifting the lid at scheduled intervals during measurements and closing it between measurements. This periodic opening allows gas exchange to occur at appropriate moments while maintaining evaporation prevention during incubation periods, thus resolving the contradiction between gas supply and evaporation control.

The patent applies the self-service principle by implementing an automated lid lifting mechanism that operates without manual intervention. The system automatically lifts and closes the lid based on measurement schedules, eliminating the need for manual handling while maintaining measurement accuracy and gas exchange requirements. This resolves the contradiction between measurement reliability and time consumption.

The patent extracts the lid lifting function as a separate, dedicated mechanism integrated into the microplate reader, rather than using a complex general-purpose robotic system. This specialized extraction approach provides automated lid handling with minimal additional complexity, resolving the contradiction between automation extent and device complexity.
