I. Introduction For the final project, our group
wanted to tackle issues surrounding the
laundry process. As weekly users of the
laundry system, we felt there was room for
design improvement in terms of its usability
and aesthetics. We wanted to address
problems related to time and convenience
and have this in mind before we constructed a product solution. During the idea formulation process,
we found inspiration through some websites, particularly Yanko Design’s webpage that featured a
washer dryer combo model. After looking at these different designs, we saw many flaws that we wanted
to fix, and were able to come up with some different ideas for our product vision that drove it to the
next level. We felt that the user demographic should be a group that we were familiar with, thus it was
decided that college students would be the targeted user group. With the user and their needs in mind,
the concept of our product would involve a portable basket that could be implemented inside a washer
dryer combination machine. All of the different design ideas we had came together to create Oasis, the
all in one washer and dryer that makes doing laundry much less of a hassle.
II. Concept
Problem
The laundry process can be quite a hassle, especially for busy college students; it is a time
consuming routine that must be forced into a weekly schedule. Typically, a student must make three
trips to a community laundry room: the first involves bringing the dirty clothes to be washed, the second
4
involves switching the wet clothes from the washer to the dryer, and the third involves extracting the
dried clothes from the dryer. Although the community aspect of a college laundry room allows for
positive social interaction, items of clothing can be lost or stolen and handled carelessly by other
students impatiently waiting for their turn. Often, students will place already washed or dried loads on
the tops of the machines or other surfaces in the laundry room to make room for their own loads. This
poses the problem of an unhealthy setting, because other people are handling your clothing, and clean
clothes are often dropped on the dirty floor. Thus, we decided that the laundry process could be altered
to benefit the needs of the user more effectively.
User
A washing machine and a dryer are two machines that are integral to the clothes cleaning process.
Not all living areas have the space for modern machines which are fairly large, such as small apartments
and college dorms, and thus community laundry centers must be utilized. Landromats and campus
laundry rooms are examples of these centers. Our group decided to focus on college laundry rooms
because community centers, like a Landromat, are exploited by a larger user demographic with more
specific and complex needs. Therefore, it was decided that on-campus college students, aged 18-22,
would be the targeted user. As college students, we are subject to the laundry process on a weekly
basis; we have endured the hassles that come with the college laundry experience. We are experts on
understanding the user’s struggles and therefore can create a product solution that meets the user
needs.
Although college students are the targeted user demographic, this product would be advertised
towards those who are actually purchasing the product: colleges and universities. The name, cost, and
durability of this product were thought out with the consumers in mind, while the usability and
5
aesthetics of this product will be designed with the user in mind.
User Needs
A more time efficient laundry process to benefit busy schedules
A faster washing and drying time period
Eliminate some of the trips to and back from the laundry room
o a way to keep clothing from being dropped on the floor between cycles
Quick detergent measuring and application process
A simple and easy-to-understand user interface
o Ability to customize wash and dry cycle
A convenient laundry bag to carry clothes to and from laundry room
Appropriate spacing and arrangements of machines; there is a comfortable amount of space for
the user and it still promotes social interaction
Laundry room designed to handle chaos of crowded periods
III. Specs
Aesthetics/Usability
From a usability standpoint, the Oasis has many functions that directly assist the user in using
the machine. The washer/dryer will be mounted on the walls about three feet above ground level, a
height that is most convenient for people of all heights. This reduces the difficulty of putting the basket
into the washer by mounting at the average height that someone would carry a basket full of clothes. A
colorful stripe on the basket clearly shows the user which side should be facing outward when inserting
6
it into the machine. When the basket engages with the back blade, it
triggers a release of two retractable blades, which tumble the clothes in
the wash and dry cycles. The handles allow for easy carrying of the basket
for any position that the user finds comfortable. The handle on the
machine is a concave addition to the front that will fit any hand size, and
lifting the door open is made easier with a weighted back that will pull it
open after being raised to a certain point. The screen allows the user to
customize the wash and dry cycle combination, or to simply choose a
standard wash/dry cycle. The platform of the touch screen is at a 45
degree angle so it can be easily read and a selection can be made from any level. All of these functions
were designed with the user in mind, and make doing laundry a much more tolerable chore.
The Oasis will be modeled after classic washing machines in terms of materials. We need our
product to be as durable as a standard washing or drying machine in order to be a strong competitor.
There are many different kinds of laundry machines, including combination machines, which are
currently used mostly in Europe and Asia. LG Electronics, Whirlpool, Kenmore, Maytag and GE are all
large name brands of appliances that make competitive grade washing machines and dryers. In the US,
the current trend in washers and dryers are front loaders, which are more efficient and energy saving
when compared to top loaders: top loading washers use three times as much water as front loading
machines. In Europe front loading and washer/dryer combination machines are largely used; top loaders
7
have been almost completely phased out. According to Bryce Wells of Fisher & Paykel, front loaders are
popular in Europe because it is a more utilitarian model; they are frequently located in the kitchen and
used as a counter top, whereas in the US, laundry machines are generally located in the basement due
to ventilation needs. Our washer/dryer combo will utilize a vent-less drying system, so it will not be
necessary to have the machine condemned to the basement any longer, but instead will allow for
customization of location based on personal needs.
Laundry detergent is a fairly complex part of the process, and there are different kinds of
detergent for front loaders and top loaders. But there is a recent development called 3-in-1 Laundry
Sheets which have the detergent, softener and anti-static sheet all in one convenient sheet that you
place in the washer and then into the dryer. This product would perfectly accompany the Oasis machine.
The Oasis’s design is very aesthetically driven while keeping the user in mind. The very sleek
shape with the cylinder fitting into a boxy shell suggests a very clean look. Washing machines are
generally white or black, because those colors evoke a clean image. The Oasis is completely white with
accents of blue in the handle and touch screen platform. Sharp angles with a curved front are very
aesthetically pleasing, and the touch screen adds to the “technologically advanced” appearance. The
basket itself also has the fresh image, completely black with white stripes.

Mechanics
Put very simply, a combination washer dryer system works by first introducing water and soap
to the laundry load like a normal washer. The clothes are washed and tumbled in a horizontal drum for
a specific time depending on the wash setting that was previously selected. This process is made up of
many different spin speeds and additions of water to rinse out the soap. The metal drum that the
clothes are in is then heated, and the hot air takes up moisture from the wet clothes, which is circulated
through the machine and leaves through the water drainage tube in the form of water. Having a
washer/dryer is a huge space saver, as well as a time saver.
Another mechanical aspect of the Oasis is the door system. Because the basket is loaded
through the side of the drum, there are two water tight doors to open. The inner door slides similar to
the way a garage door opens using a
track system. The outside door is
fixed on an axis, and opens like a grill.
When the Oasis is not running, the
doors lock to each other and lift
together with one simple motion.
9
Once the door is closed and the wash/dry cycle is selected, the inside drum separates and spins freely,
leaving the outside door to lock and protect the user from contact with any moving parts.
Materials
As seen in the pictures and text description, there are many aspects to the Oasis. The outer
casing of our machine will be made of a thin polypropylene plastic sheet which encases all of the
mechanics as well as the spinning drum. Inside of the rectangular body seen there are four sections: the
part that encases the mechanics, the outer waterproof shell of the drum, the drum itself which spins,
and the laundry basket inside, connected to the drum during the washing and drying cycles. The outer
layer is what catches the water as it comes out of the main spinning drum. It will be injection molded
polypropylene plastic parts. This layer will also contain the outer layer of the door, so it will have a
watertight latch that will engage when the wash cycle begins. This latch will then disengage at the end
of the cycle and the door will align with the inner, spinning, cylinder so that the two doors open
together wide enough for the basket to be removed, as described earlier.
The next layer down is the drum of the machine. It is the part of the machine that spins in order
to tumble the clothing and allow the water and soap to circulate throughout all of the clothing. The
cylindrical layer is made out of sheet stainless steel, as it needs to be durable yet light enough to be
mounted on the wall and completely watertight. This type of material can be purchased for around $30
per drum made. This drum needs to be metal in order to allow assistance in the drying process because
the clothing dries partially due to touching the hot surface of the spinning metal. The steel will be
coated in zinc to improve rust resistance; this is a common process with modern washing machines. The
drum will be machined with a press; it will be pressed between two halves of a mold to form the
appropriate diameter drum. The washer blades that reside on the inside of the drum will be made from
polypropylene plastic, as they do not need to be metal since they are only tossing the wet clothing
10
around inside the metal drum. Each blade will be made of two slabs of this plastic as they need to be
able to lay flat and then bend up into a triangle, because two of the blades retract when the washing
and drying cycles end.
The transmission is usually made out of cast aluminum which starts as 20 pound slabs and is
then formed in die cast machines. The rough mold is then shaped by various machines that smooth it
out and shave off excess metal. These parts are then assembled manually and the machine is put
together.
The innermost level of our system is the laundry bag. It is made of polyester so as to be durable
yet flexible and breathable. It is important that the basket be breathable because clothing needs to be
able to air itself out while waiting to be washed. If it were trapped under layers in a non-breathable
material, the clothing could possibly become mildew covered. The basket contains three inlets where
the blades of the machine will match up and hook up to the basket. This way the inner drum of the
machine will have a tight fit to the basket and the basket will spin with the drum. Also, the mesh
polyester will align with the drum so that the heat from the drum can still be felt through the material. A
fourth striped section is located on the basket to allow the user to know which way to insert the basket
into the machine: stripe side out. The basket has support that keeps it upright but still pliable to allow
easy insertion into the machine by the user.
Environmental Impact
Electric washers and dryers can consume as much as 25% of the electricity used at home,
including hot water for the wash. As much as 90% of the energy consumed by washing machines heats
the water; reducing the water temperature reduces energy consumption. With these facts in mind,
there is definitely room for improvement. Over the past ten years, washer and dryer manufacturers
have made huge efficiency strides in reducing water consumption, energy required, and even detergent
11
needed to launder a clean load of wash. The front loading feature of our product with a horizontal drum
typically uses less water, heat, and detergent than that of a vertical drum; the horizontal drum spins out
most excess water, so that significantly less time is required in the drying cycle.
In terms of materials, the stainless steel of our product is environmentally friendly as this
material is 100% recyclable. Old re-melted steel scrap creates new stainless steel in the full life cycle.
The polypropylene plastic of the outer casing is one of the mostly environmentally friendly plastics to
choose from. Plastic is generally not recognized as an environmentally friendly material. It is important
to choose a plastic that is safe for both humans and the environment when deciding what material to
use to manufacture a new product. Polypropylene plastic is acknowledged by the Society of Plastics
Industry as one of the safer plastics. This plastic does release some harmful toxins, including BHT,
Chimassorb 81, Irganox PS 800, Irganix 1076, and Irganox 1010, but these toxins are far less severe than
those of most plastics. Polypropylene is a #5 plastic, which is recyclable. The waste produced from the
process of making the machine itself will be easily recycled and reused. The left over sheet metal can be
sold and used for a different manufacturing project. Thus manufacturing of this machine will not have a
huge environmental impact.
The mesh polyester of the laundry basket is considered to be detrimental to the environment.
Polyester, which is the most widely used manufactured fiber, is made from petroleum. The manufacture
of polyester and other synthetic fabrics is an energy-intensive process requiring large amounts of crude
oil and releasing emissions including volatile organic compounds, particulate matter, and acid gases such
as hydrogen chloride, all of which can cause or aggravate respiratory disease. Volatile monomers,
solvents, and other by-products of polyester production are emitted in the waste water from polyester
manufacturing plants. Many polyester manufacturing facilities are considered to be hazardous waste
generators. With this said, future iterations would call for a different material to be used for the basket,
12
but at this stage of our product, we found polyester to be the material best suited for the problem.
IV. Competition For a while now, the necessity to wash and dry clothing has been almost as basic as the need for
clothing itself. Washing machines have been in existence since the early 1800s, during the industrial
revolution, and the dryer came soon after. Overtime, the washer and dryer have become integral
components of the family household. Washer dryer combo machines, on the other hand, did not appear
on the market until the latter half of the twentieth century. Today, washer dryer combos are far more
popular in Europe and some countries in the East; in the U.S., these units are slowing gaining more
popularity as a practical and functional laundry solution. Combos are popular in smaller urban living
areas since these machines only need half the amount of space usually required for a separate washer
and dryer and they do not require an external air vent. This space-saving feature would be convenient
for the college laundry rooms, as it would allow room for more machines. The combos also allow clothes
to be washed and dried “in one go” saving time and effort for the user; this feature would be especially
beneficial for the user. While combo washer dryers are not as effective and efficient as some full-sized,
fully functional, separate washer and dryer machines, the combos provide a viable option for those who
can benefit from having a compact machine that is able to wash and dry clothes and gets the job done in
a shorter amount of time than the two separate machines. With that said, the washer dryer combo
machines serve to meet the needs of the user and the standards of the consumers.
Currently there is already the technology in place for a combination washer/dryer system,
however, our product will use this technology along with our new laundry basket design to break into a
new market niche. There are hundreds of washer dryer combo models made from numerous brands
including Whirlpool, Kenmore, Maytag, Frigidaire, Haire, Ariston, LG, and GE. The following models are
some of the more popular combos on the market:
13
Frigidaire GLEH1642FS
This model is considered a washer dryer combo, but it falls under the category of ‘stackables’: a dryer on
top of a washer. The washer is front-loading and has a capacity of 3.1 cubic feet. The dryer has a
moisture sensor, which can tell when clothes are dry so energy is not wasted. The fast drying times
would be beneficial for our user demographic; the compact size and energy efficiency would be
favorable to our consumers. However, the separation of the washer and dryer does not keep the user’s
need in mind.
Ariston AWD121NA
This model goes for a reasonable buy of an estimated $1000. This product is widely available in Europe,
but this company name is less well known in the U.S. It can wash thirteen pounds and dry nine pounds
of laundry per load, and if the user fills the washer up to capacity, they will have to remove some items
before drying. Other features include a delay start timer, electronic controls, nine wash cycles and a
one-year warranty. The difference in capacity between the washer and dryer are not very appealing for
the user, however the price may be favorable to the consumer.
14
Haier HWD1000
This model goes for a great buy of an estimated $700. It is one of the most inexpensive washer dryer
combos available and it is very compact. This product is very easy to use with a 1.7 cubic foot capacity,
even wash cycle, an electronic panel and a one year warranty. Although this product has many positive
features, it provides the user with damp and wrinkled laundry and leakage. These negatives would not
be beneficial for the both the user and consumer.
LGWM3431HW
This washer dryer combo product is one of the most highly reviewed products on the market. It goes for
an estimated $1,350; it is more expensive than the previous models, but it is worth the purchase. This
15
model is 24 inches wide with a 2.44-cubic-foot capacity, which is larger than most competing products.
It has nine wash/dry cycles, including a sanitary germ-killing cycle that heats water to 158 degrees
Fahrenheit, and a moisture sensor, which turns off the dryer automatically when laundry is dry. One of
the few negatives is that the drying process takes longer than most separate drying machines. The
features of this product would benefit the user, with an exception being the long drying time. The good
reputation of this model would be appealing to the consumer.
Market Potential
Our product, Oasis, is a good competitor in the market of all-in-one washing and drying
machines. The goal price is $1,100 per machine, and then each basket would be sold for $10, which is
around the same price as a current pop-up, stand alone laundry basket for a college dorm room. The
college would purchase as many machines as they would be able to fit in their current laundry facilities
(approximately twice as many washers as there are currently) and then sell a basket to each incoming
freshman. In this way, the institute will be able to regulate what kinds of baskets are placed into the
machines, and they can insure that it is only used appropriately. Additionally, the product works as a
normal washing machine if the basket is not purchased.

V. Overview The Oasis is a new way to do laundry without changing the habits which are already so ingrained
into our heads. College campuses have a community laundry facility that most students take advantage
of on a weekly basis, and our proposed solution is designed with the user in mind to reduce the chances
of other people handling clothing or dropping clothing in the process of washing. The sleek design
makes it aesthetically pleasing, and the mechanics of both the washer/dryer machine and the
interlocking doors allows our design to be above those that are already on the market in terms of
usability and satisfying user needs. The Oasis will constitute a complete overhaul of any community
laundry room on a college campus, but it will be in the college’s interest to switch over to our new
system as it will make the whole laundry process much easier for already stressed college students.
