Engineering Priorities

The Porticos engineering team focused on creating detailed volume-manufacturing specifications that maintained the precise design intent of the device:

• Design of Livi™’s adaptable pill-delivery system, which accommodates all dosage configurations (including size, shape, type, and combination of pills)
  The system can be configured to feed pills that measure less than 5mm and up 30mm in size. A single machine accommodates up to 15 different types of pills at once. A reliable pill feeding and counting mechanism was developed with many rapid iterations of 3D printed prototypes.
• Detail design of parts for production manufacturing processes, including injection molding
  Guided by preliminary industrial design sketches, the team created 3D models of complex exterior surfaces and developed the models into detailed part designs for injection molding. 3D printed prototype mechanism designs were evolved into detailed designs for high-volume injection molding. Internal structure was designed to utilize sheet metal parts for volume production and low tooling cost.
• Support user trials and FDA Certification by procuring materials for a 30-unit build and establishing the supply chain and coordinating the materials in the build process
  The team created and maintained a bill of materials and assisted in supplier selection. Our engineers fully assembled and functionally tested all prototype machines.
• Preparation of the units for internal pre-scans and IEC 60601-1, -1-2 and -1-11 testing
  The design was performed upfront to meet medical device requirements. Our team also incorporated rapid design changes in response to early testing results.
