Hi my name is Curtis Lindsey.
And my name is Heather Joannou.

and we're both fourth year bio-mechanical
engineering students

At Queen's University

For our fourth year Capstone Project

We developed a Pommel for
Advanced Mobility Systems

So our device is a wheelchair accessory
called a Pommel

And what it does is it helps people
who don't have control of their bodies

Sit in certain positions in the
wheelchair

Which is a wheelchair manufacturer
here in Kingston Ontario

So we started with their original Pommel
which had no adjustability in the cushion

As well as didn't optimize comfort for
the user

We modified their original design to be
more adjustable

And more comfortable for the user
as well as more functional

So we actually met with a

Resource Centre named Ongwanada
In Kingston

Where we got to meet with an
occupational therapist

and they tested the device on several
different clients there

They had really positive reviews

they talked about how easy it was
to use

And how the adjustability features that we
added

really made it more comfortable
and helpful to all their clients

So one of the major problems
that people were facing

Was that the cushion just came in
one size

So with our new prototype we have two
independent cushions

That are adjusted with the use of
an Allen key

So the user, when they first get
our Pommel

They don't have to worry about ordering
different size cushions based on their needs

they can fit it right with their
device that they buy

There is adjustability in where along the
thighs that you want to place the Pommel

So this so this is just a huge thing
for people with disabilities

Because often their legs aren't conformed
to the straight femur that's normal

So this adds comfort for whether they're
bow-legged or anything like that

And it can just comfortably sit
against their femur

So we've had a couple other projects
that we worked with clients

But not as closely as we have
with this project

So this project we had a full year with
the client

they helped us design
and look at our design

And say "no we don't really like that
or it would be easier to manufacture this"

A struggle with that though is that
it often got off our timeline

Because the company had big orders
they had to fill

And didn't have time to complete
our prototype

But the professors are very adaptable
and they gave us lots of time

To adjust or design and our reports

So the course just gave us a chance
to try out product development

Really follow a device from the
very beginning of the design

To an actual prototype and testing

Which was really cool to see it
from beginning to end

I think that this was a really cool
project because

It drew from both of our bio-mechanical
backgrounds

All the different courses
that we've completed

Over our time here
but then put it into

A real world experience, where we
have an actual problem

That we need to address and we have
real clients that have deadlines

And we work with closely
