Executive
Summary
The objective for
Project Two was to design and fabricate a device to aid the Marianist community
in their universal goal. After interviewing a Marianist and conducting
research, the team had a general idea of the various options available. During
group discussion, each member presented ideas to the group for consideration. The
options were recorded and after deliberation many were rejected. After learning about elderly citizens
struggling to put on their socks, Team Zayad created the Ultra-Sock 2000. The Ultra-Sock
2000 is designed to aid the elderly and disabled with putting on their socks.
The Ultra-Sock 2000 has a frame in which to position the sock. The user, going
toes first, slips on the sock, guided by the plastic slide. The handles have
double features as a shoehorn and a sock grabber. With the completion of
fabricating the Ultra-Sock 2000, the team reached its objectives and goals with
convincing success. The Ultra-Sock 2000 works very nicely, helping to put on a
sock with great efficiency.
Introduction
The challenge for Project Two was to
design something which would help the Marianist mission. The team focused its
research on helping the elderly and disabled, and decided to work on a noble,
basic, and practical tool which can make the beneficiaries more independent and
able to overcome the difficulties that they face during their daily tasks. One
of the problems the elderly and disabled face is the need of others’ help to do
a simple task such as putting on their socks; therefore, the team worked on
easing the burden and make the targeted group more confident.
The team kept in
mind some objectives to reach. The first goal the team attempted to reach was
helping those people to feel more comfortable and able to perform their own needs
by themselves. The team set up a certain level of quality, durability, and
practical benefits which need to be achieved, for example, having an
appropriate size which covers as many foot sizes as possible, or using such
sturdy materials which will not add too much weight to the tool to increase
user friendliness. The team wanted their tool to be highly practical, so the tool
did not settle on being solely a sock “putter-onner”. The team went further to
create handles which work as a shoe horn and help taking the socks off or even
grab them from the ground when needed.
The team also
faced some constraints which need to be addressed. One of those constraints was
making reliable joints connecting sock “putter-onner” portion with the two
handles, which took some time until the team agreed and found the appropriate
materials for the joints. Another self imposed constraint the members faced
during their design selection was to stay within the goal agreed upon. The team
did not want to have a complicated tool requiring heavy detailed work or large
amounts of money, because the goal was making a practical tool which did not
cost a lot of money, but could support the targeted group, and could spread
widely.
Regarding the
requirements, the project’s supplies should not cost more than $60. The group
succeeded on not exceeding the limit, as the allocated budget was only $20. Finally, the
project was to be completed in time for the established due date.
The project leader
had made some calls and contacted some members of the Marianist community who
explained their needs, and after contacted, the targeted group of focus for the
team had been narrowed down. As a result, the team chose to aid the elderly and
disabled. So in order for the team to choose their final project, every member
has done his or her own research and looked up further information which helped
so much to arrive to the final idea, a combination between the members’ ideas.
Design
Alternatives
Team members did research about the Marianist Community to
know their goals. The team presented some difficulties the Marianists face,
such as how to help the elderly mobilize, education, help the elderly and
disabled in general to become more independent. Conceptual sketches can be seen
in appendices A and C. The team decided to concentrate on aiding the elderly to
become more independent rather than being dependent and waiting for people to
help them. The team members discussed helping the elderly and disabled to get
in a van by inventing a ramp which could help them to get in the van without
any help and with a small amount of money. (Appendix B) However, the team found
some difficulties on how they could build the ramp; so the team rejected the
idea. After, the team decided to find another way to could help the elderly
people to live a more independent life. The team came up with the idea of the
Ultra-Sock 2000, which could help the elderly and disabled to put on their
socks without any help. The next step was to discuss how the Ultra-Sock 2000
could be built.
The team came up
with many different designs for the Ultra-Sock 2000. Each team member presented
different designs of the Ultra-Sock 2000. The team then discussed the designs.
These designs were narrowed down to the features the team wanted to incorporate
on the final design. The team found a way to incorporate several features to
improve the final design. Some of the features the team conceived included a shoehorn,
and a sock picker-upper. The team voted on what aspects would be included in
the final design. A drawing of the final design was then made to show how the
elected aspects fit together. The final design was then assessed with the
measurements of each feature. The layouts of the final design pieces were then
drawn to show how the team would fit the pieces of the project together.
Design Selection
Each member of
the team developed different ideas for the sock “putter-onner”. The team met to
discuss the different options presented. The team decided the design should
include multiple functions because the target audience of the product is people
with limited mobility. The aspects of the design which would be focused on were
putting the sock on, taking the sock off, and helping to put on shoes. The
ability to use the product safely was also a key point in the design. Other
elements the team focused on when creating designs were ease of use,
flexibility, sturdiness, and movability of the parts of the product. The team
rejected some of the presented ideas because the designs did not meet the
requirements. One alternative design which was rejected was to have a wooden
base on the product. The wooden base was rejected because the team felt a base
would be too heavy and hinder ease of use. Another rejected alternative design
was to have a dual system unit. The idea was rejected because the team felt a
dual system unit would impede use for the target audience and cause safety issues.
(Appendix D)
Final Design
The final design
the team chose used a wire frame with a plastic slide and multifunctional
handles. The metal frame, constructed from 9-guage wire, was bent into a design
which could cradle a sock. The three-dimensional shape of the frame bends into
an L shape from a nearly nine-inch rise from the connection point, and bends
back down after about three and a half inches. From there it drops down for
another three inches and bends sharply out at a 90-degree angle. This loops
around in an arch until it returns up in the same way it bent down. The plastic
slide, measured at six and a half inches, is a half pipe cut from PVC piping.
The frame is connected two and a half inches down from one end of the pipe. This
orientation of the PVC pipe from now on to be referred to as the top, with the
reverse end described as the bottom. The multifunctional handles are connected
with very close dimensions to each corner of the top of the pipe—approximately
half an inch from the top and side. These handles are bolted on with loose
joints such that they have nearly free range with the exception of the wire.
The Ultra-Sock
2000 provides optimum sock “putting-on” experience. Offering multiple
functions, the Ultra-Sock 2000 boasts a durable and impressive sock putting-on
experience. However, the current version contains relatively sharp corners and
slightly heavy materials. This failed to meet one of our constraints, to make a
lightweight design. The weight of the sock putter-onner is not heavy or
cumbersome to use, but it is not lightweight. The weight would not be an issue
in the execution of use. A final weakness worth mentioning is the ease of use.
The Ultra-Sock 2000 is not necessarily an intuitive design. There are
specifications with how to mount the sock. However, it is not a difficult
process to learn, and the proper application of the sock results in an
exceptional sock putting-on experience.
Technical Aspects
The engineered
design for the Ultra-Sock 2000 required many scientific and mathematical
principles. Most of the math used in the design was used to measure the parts
of the design and the way of attaching them. The team decided to use a long
shoehorn to make using the Ultra-Sock 2000 easier with a length of 18 and a
half inches. The shoehorn cost the team $11.29. Also, the team used a PVC tube
as plastic slide and that cost $7.53. The team cut the PVC tube to make a
plastic slide; the team decided to cut this 6.5 inches in length with a diameter
of 4.25 inches as the width of the plastic slide. Moreover, the team bought a
metal wire for $10.98 to use as a frame of the Ultra-Sock 2000. The
measurements of the wire frame were 6.5 inches in length and 3 inches wide. In
addition, the team used nuts with blots to attach the parts of the Ultra-Sock
2000. The nuts were 5mm width and the team bought the nuts for $4.68. Also, the
blots were 5mm width by 25mm length and the team bought the bots for $1.97.
After attaching all the parts of the Ultra-Sock 2000 the total length came out
to be 23 inches with a width of 4.25 inches. In addition, the team achieved the
requirement of the project by being within the budget. The team spent only $36.45
on the Ultra-Sock 2000 which made the team spending about two thirds of the
whole budget and saving more than one third.
Testing the Design
The construction of the Ultra Sock 2000 began with the cutting of the
PVC pipe. The PVC pipe was to be used as a guide for the user’s foot. The team
first cut off a smaller section of the PVC pipe. The smaller section of the PVC
pipe was cut in half to be the semi-circle guide. The next step was to drill
holes for attachment purposes in the PVC pipe and shoehorns. One hole was
drilled in each of the shoehorns and four holes were drilled in the PVC pipe:
two for attaching the shoehorns and two for attaching the wire frame. The holes
for the wire frame, which would hold the sock, were drilled at an angle in
order to the keep the wire from sticking out too far. The wire was cut, shaped,
and attached to the PVC pipe. The shoehorns were attached to the PVC pipe with
a nut and bolt. Members of the team conducted the tests of the Ultra Sock 2000.
A member of the team tried to put on a sock using the device. From the first
test an issue became apparent, which was the sock not staying up on the wire
frame. The team resolved the issue by lengthening the wire frame and reshaping
the wire. A bend was put in the back of the wire in order to keep the sock from
sliding down. The team retried the test to put on a sock. At first the sock did
not go on how it should have, but with experimentation on mounting the sock in
the frame, the team found a solution. The test to put on the sock was
successful.
Results
When the building process of the
Ultra-Sock 2000 had reached its end, it was as same as the team conceived it to
be. The Ultra-Sock 2000 came up with the right measurements that can fit as many
different foot sizes as possible. The Ultra-Sock 2000 has also shown its
strength after being tested by the team, which removed all the concerns the
team had about the durability of the joints.
Conclusion
The design has met all the objectives and
goals which were set up by the team. The first goal for the team was building a
tool that can help elderly and disabled people and add something to the
community, and that was what the Ultra-Sock 2000 did. By using the Ultra-Sock
2000, wearing socks became easier. The technical goals of the project included
a frame size that could conform as many foot sizes as possible, and this is
what the team did. The team arrived, after two trails, to a frame size that
would fit different foot sizes. Another goal for the team was building durable
joints that last long and do not break easily, and the team succeeded in having
durable joints that show its strength after being tested. Another goal the team
worked on having in the device was making a tool that could be used for
different purposes, so the team did not only build a socks putter onner, but
also a shoe horn and a sock grabber. With all those goals accomplished by the
team, only $36.45 was spent from the $60 budget
supplied by the University of Dayton.
Recommendations
The team had several mistakes that they had
not thought of or planned for before starting to build their design. The first
problem the team struggled with was finding a way to cut the PVC pipe
perpendicularly into equal halves to get the half-moon shape which would be
used as a foot slider. However, the team used handsaws to cut the PVC pipe,
even though that created some unequal or sharp edges that the team had to
equalize and smooth off afterwards, it would have been more efficient and
easier if the lab contained a safe way to utilize electronic saws.
Another point that postponed finishing the
Ultra-Sock 2000 was not having a clear vision of the frame size, because there
was not enough information which the team can collect in order to choose a
frame size that can fit different foot sizes. Once the team had finished with
building the Ultra-Sock 2000 and started testing it, the device did not work
well because the size of the frame could not fit a normal foot size. However,
the team had enough time to rebuild the frame and get it done in a short time,
but with more practical frame size this time. So the team could have avoided
the problem by doing their own research and not relying on expectations.
One last problem faced the team while creating the frame was not having
a tool which could cut the wire into appropriate length; furthermore, there
were no tools to help shape the frame. In that case the team needed some manpower
in addition to the tools, so the members were using their power to cut the
sturdy wire, and to shape the final design of it using their own hands which
cannot be as accurate. However, if there were a safe way to heat and bend
the wire it would have been better, because that would make the metal wire
easier to control.
Recommendations
Size Adjustments
One recommendation that can improve the
Ultra-Sock 2000’s practicality, in the event it would be produced, is having
different sizes of the foot slider and the metal frame. The team tried their
best to come up with a size that perfectly covers as many different foot sizes
as possible; however, that size still has its limitations where it cannot fit
larger or smaller foot sizes.
Aesthetics
For
beauty and quality purposes, the Ultra-Sock 2000 was going to look better if it
was possible to paint it. The team did not paint the Ultra-Sock 2000 for several
reasons; one reason is that painting a tool that would be interacting with the
body needs specialists who can provide some paints with no side effects on the
skin of the human body. Another reason the team did not paint the Ultra-Sock
2000 was the possibility of paint rubbing off onto a piece of fabric that may
touch the tool, because the team did not want to ruin the users socks or
clothes.
Smoother Edges & Hide Bolts
Another point the team could work on
better was finding a way to hide bolts so it does not create any kind of
problems for the person who is using it. Also, the edges of the Ultra-Sock 2000
were a little bit sharp, so it needs to be smoother to avoid hurting the user’s
foot while using the tool.
