Mechanical Mechanisms

Context: Team sponsor Johnson & Johnson tasked us with
creating a solution for the rampant plastic and metals waste
coming from single-use devices, desiring to position their
company as a leader when it comes to creating a circular
economy within the MedTech and Healthcare sectors.
​
Solution: The Pathfinder bin is a sorting and data tracking
product which enables discarded devices and high value
materials to enter the Repath system of recollection,
decontamination, recycling, and distribution of recycled
materials to enrolled parties across industries. It allows for
traceability of materials from point-of-origin (OR room)
through to distribution by utilizing sensors that send data to
the Repath Database, which is used to organize and send
appropriate data to stakeholder groups (i.e. the Repath
orchestrator/operator, the manufacturers, the recycling center,
and the hospitals). This solution also successfully met our
objective of creating a system that is minimally invasive to the
standard operations of medical professionals.
​
My role: User research/interviews, initial CAD assembly, researching and testing computer vision program, setting fixture parameters for physical implementation of computer vision sensors, database schema design, creation of live websites linked to database, hardware/platform/frame manufacturing and assembly
