Auto-injector development carries a unique level of risk. Not because of any single challenge, but because product performance, manufacturability and scalability must all be achieved simultaneously. These requirements are often evaluated under different conditions and at different stages of development, limiting visibility into how design decisions will perform in high-volume manufacturing and automated assembly and in the hands of the end user.

When designs are translated into high-volume manufacturing and assembly, these gaps in visibility and alignment become operational constraints. Component design influences not only…
