Project Background Snug Seat Product Guide 2013 Pediatric
standers provide upright mobility for children with certain types
of disabilities, allowing the user to move and interact in a way
that is more natural than a standard wheelchair, while also
allowing the user to bear weight on their legs; a critical part of
current physical therapy practices. The ultimate end goal of this
project is to produce a safe and repeatable motorized attachment
for a pre- existing pediatric stander. 9/30/20143

Project Statement & Deliverables Problem Statement The
primary objective of this project is to deliver a working prototype
that will allow the client to control the movement of the stander.
Additionally, the care provider will be able to safely control the
movement of the stander, and override the user input with a remote
control. Finally, the project will be packaged and made available
for families with a disabled young person. Deliverables Functional
prototype Functional wireless remote control for client safety and
training DIY kit comprised of componentry, clear assembly
instructions, and support information 9/30/20145

Action Items 9/30/20146 VOC and VOE revised Customer Needs and
Engineering Requirements do not align CR18 redefined and quantified
CR18 Provide the user with a sense of freedom and independence
suggested to be too liberally worded and hard to define Currently
in progress FDA ban Stander availability Available funds Need to
define which stander to begin project work on

Physical Therapy could be performed on two students at once A
student could take one stander home No tear-down time Previous
teams modified past standers frame. Increased contact time between
P15045 and stander Cost Modify Blue Stander Cost Previous teams
documentation Tear down required Eliminate a useful stander Too
large for the majority of Lindas students Limited access to the
stander during rebuild Kitting would produce double components for
frame Modify Red Stander Stander fits a majority of students Cost
Tear down required Eliminate a useful stander Limited access to the
stander during rebuild Unclear documentation

Feasibility Analysis 9/30/201436 How much would a parent be
willing to spend on a DIY kit for a motorized stander? Rabbit
Stander: $2,070 Motorized Wheelchair: $4,000 Is it feasible to
produce a kit for $500? Original BOM cost : $1,600 Reduced BOM
cost: $1,400
