Gilead Sustainable Autoinjector Engineering Analysis
Abstract/Contents
- Abstract
- In 2017, nearly 17 million autoinjectors were sold worldwide -- a number that is projected to quadruple by 2030, as patient populations move from daily tablets to long-action injections. The only commercial method of disposal is incineration, motivating engineers to create a more sustainable single-use autoinjector that effectively decreases the irreparable environmental damage caused by high energy demands from current disposal methods and production of virgin plastic material. With the goal of reducing the volumetric contribution to landfill per injection, our team developed an autoinjector assembly that allows for the separation of the biohazardous injection mechanism and the recyclable outer shell. Leveraging the shear pin's characteristic to fail at specific torque loads and deter reassembly, and using the bayonet's characteristic to carry high axial loads, a hybrid of these elements has been extensively tested and iterated upon to create a two-step separable mechanism that culminates in the ability to recycle the appropriate autoinjector components.
