We have a new group member
• Jordan Smith expert consultant on
all things computer
programming
Problem Statement
•Design an Accessible
Medication Dispensing
Device. The device must be
automated, and capable of
dispensing drugs only to a
specific patient, and with
patient-specific doses.
Aims
– Affordable
– Dependable
– Simple
– Safe
– Flexible
– Scalable
Specifications
Needs to:
–Cut pills into halves or
quarters.
–Dispense medications.
•Ideally, it will:
–Interpret a container’s bar
code
–Track medication expiration
dates
–Remind users to take their
medications
–Track what medications
have already been dispensed
Bar Code Scanners
• Two types of scanners:
– Serial
– Keyboard Wedge
• Three types of interfaces:
– Keyboard Wedge (Keyboard
Wedge Type)
– RS232 (Serial Type)
– USB (Either Type)
Bar Code Scanner Cost
• Available Options range between $150 to
$1000.
• We will need to spend between $200 –
$300 for an adequate scanner and
supporting software.
Three Ideas Thus Far
• Conveyor Belt
• Loadable Tray
• Blister Pack
Conveyor Belt
• Made a prototype
• Decided that the design was to complex
• Will need to simplify and redesign
Conveyor Belt
Conveyor Belt Cutting System
Loadable Tray Prototyping
• Built Prototype with epoxy
• Epoxy wouldn’t release from tray, kinda
ruined it
• Near impossible to keep razor blades at
90º angle
Loadable Tray
Blister Pack
• Have pills come in standardized blister packs
• Pros
– Pills separated
– Environmentally Sealed
– Ease in cutting and in dispensing
• Cons
– Less Convenient, relatively few medications currently come in
blister packs
– Not as universal
• We can make it work but requires implementation of
blister pack technology
Blister Pack Schematics
QFD
Where do we go from here?
• Discuss different designs
with our advisor and a
mechanical engineering
professor
• Working prototypes
• Refine ideas
