Blender Locking Ring Stop System to Prevent Inadvertent Disassembly

The patent implements a preliminary locking action where the locking ring must be actively engaged with the bowl through a specific rotational movement before operation. The stop system is pre-configured to block the locking ring at assembly positions, ensuring that proper assembly has occurred before the device is activated. This preliminary securing action prevents inadvertent disassembly during operation while maintaining the ability to intentionally disassemble for cleaning when needed.

The patent merges the locking function with the existing assembly structure by integrating the stop system into the relationship between the locking ring and the bowl. Rather than adding a separate blocking mechanism on the motorized base, the invention uses the bowl's structure and the locking ring's geometry to create the stop system. This combining approach prevents locking ring rotation during operation while minimizing additional complexity by reusing existing components.

The patent employs asymmetric geometry in the stop system design, where the stop protrusion and its corresponding recess are positioned and shaped asymmetrically relative to the locking ring and bowl. This asymmetric configuration creates a unique assembly position that is easily recognizable and achievable through simple user actions. The asymmetry ensures that the components can only assemble in the correct orientation, guaranteeing reliable assembly while tolerating variations in manufacturing precision.
