Pipette Single-Trigger Syringe Separation Mechanism

The patent combines the actuation of two separate syringe gripping levers into a single trigger mechanism. The trigger, when pressed, simultaneously actuates both gripping levers through a transfer element, merging two separate operations into one action. This resolves the contradiction by maintaining secure fixation during operation (reliability) while enabling rapid single-handed disconnection (productivity).

The patent introduces a transfer element as an intermediary mechanism between the single trigger and the two syringe gripping levers. This transfer element transmits the force from the single trigger to both gripping levers, enabling coordinated actuation. The intermediary allows a simple single-finger action to achieve the complex function of releasing both gripping levers simultaneously, improving disconnection efficiency without compromising fixation stability.

The trigger mechanism is segmented into distinct functional components: the trigger itself, the transfer element, and the connection points to the two gripping levers. This segmentation allows each component to perform its specific function independently while working together as a unified system. The modular segmentation reduces overall complexity by making each component simple and well-defined, rather than creating a single complex mechanism.

Instead of designing two separate triggers that each control one gripping lever, the patent inverts the approach by using a single trigger that controls both levers through a transfer element. This inversion simplifies the user interface (single trigger press) while the transfer element handles the complexity of distributing the actuation force to both levers, effectively moving the complexity from the user interaction level to the internal mechanism level where it can be managed more efficiently.
