Project Track: Assistive Devices/Bioengineering
Project DescriptionOur customer has speech disabilities and needs a
special way to communicate with people who don’t know her well
Currently uses a picture bookDesigned to current customer’s needs but can be
adoptable to other customer’s with special needs
High Level Customer Needs / Engineering Specs
Adequate product size 9”x13”x3” Adequate product weight 7 lbs. Durable and robust drop from 40” Weather resistant enclosure Long battery life 16 hrs. Attached to wheelchair mechanical arm
Technical Risk Assessment Risk: Separated computer and power components
from LCD touch screen• Separated components require
• Power cable (to power the LCD)• Audio Cable (for sound)• Video Cable (for LCD touch screen)• USB Cable (for LCD touch screen) All these cables need to go through the arm & be
detachable
• Mitigation:• Using an all-in-one cable which will transfer video,
audio, USB and power from underneath the wheelchair to the LCD touch screen.
Current State of Design
• Design Meets Customer Needs• Design Meets all engineering specifications except:
• Battery components (life, weight and power output)• All-in one cable connectivity issues• Deflection of mechanical arm
• Computer box:• Delays with ordering from Taiwan• Slow response from the company• Backup computer costs more (around $400)
• Mitigations• Have a deadline for going with the backup computer• Use a cable conduit instead of all-in-one cable• Use rubber stops on tray for the deflection of the arm
