The present disclosure is generally directed to an attachment mechanism suitable for attaching for example a module to an object that is essentially cylindrical or polygonal in cross-section, e.g. to a portion of a drug delivery device. Further, the disclosure is directed to an electronic system, which is configured to be, e.g. releasably, attached to the drug delivery device as well as an assembly comprising the the electronic system as well as the drug delivery device. The attachment mechanism may comprise a housing, a gripping portion with at least one gripping ring and an actuator for operating the gripping portion between an open condition and a clamping condition.

Attachment mechanism, module and assembly herewith

The present disclosure is directed to an electronic add-on module configured for attachment to a drug delivery device and to an assembly comprising a drug delivery device and an electronic add-on module. The electronic add-on module may comprise a first portion with a main housing defining a longitudinal axis. The module comprises a gripping mechanism allowing attachment to drug delivery device dose dial user interfaces, e.g., a dial grip, and/or drug delivery device injection user interfaces, e.g., a dose button of varying diameters and shapes. The first portion comprises on an inner side of the main housing at least two elastically deformable arms each having a clamping section which is configured to be elastically deflected radially outwards with respect to the longitudinal axis from a unstressed, nominal position to a strained, deflected position.
